36gF6eiCsqU	2024-08-04	HLX Files #0	The Half-Life 3 Leaks We’ve Been Waiting For - HLX Files #0	The-Half-Life-3-Leaks-Weve-Been-Waiting-For-HLX-Files-0-36gF6eiCsqU.en.md	1	Voice actor résumé reveals the “Project White Sands” casting codename	Fact — the claim rests on a named primary artifact, a voice actor’s résumé leak, which Tyler presents as real and says came from “a screw up by one of the voice actors on the project.”	Development state	Voice actor résumé leak, reportedly written and posted by the actor’s agency, as described by Tyler.	A voice actor’s résumé, apparently posted by the actor’s agency, revealed that Valve is casting for an internal project under the cover name “Project White Sands.” Tyler says this is the codename Valve uses to hide the real project name while casting voice actors and connects it to the HLX project. He stresses that someone at the agency or the actor’s representation made a mistake, not necessarily the actor, and asks viewers not to identify or harass the individual.	None identified in this video.	needs follow-up — an archived copy of the résumé or casting listing, without identifying the individual, would confirm the “Project White Sands” name and its association with HLX.

Development state	Résumé of a former Valve employee who left the company in 2023, as described by Tyler.	A second résumé, from a different former Valve employee who left the company in 2023, stated that between 2020 and 2023 they worked on level design layouts, lighting, combat encounters, and puzzles for an unannounced title. Tyler presents this résumé as surfacing around the same time as the Project White Sands leak.	None identified in this video.	needs follow-up — an archived copy of the résumé or employment record would confirm the dates and described responsibilities.

Tyler says “Project White Sands” is probably a deliberate obfuscation rather than a story clue. He compares it to other random Valve casting codenames: “Hot Dog” for Left 4 Dead VR and Left 4 Dead 3, and “jameroquai” (as transcribed) for Half-Life: Alyx. He explicitly declines to read meaning into “White Sands.”	None identified in this video.	unverified — casting records, agency listings, or datamined references for “Hot Dog,” “jameroquai,” and “Project White Sands” would corroborate the pattern.

Development state	Tyler’s analysis of accumulated HLX datamines.	Tyler concludes that HLX is “a fully-fledged non-VR Half-Life game,” rejecting earlier arguments that the codename might represent only an engine feature or a file format for saves. He says it is something that seemed too good to be true and that he wanted to be very sure of before publishing.	Tyler recalls the earlier argument that HLX might be an engine feature or a save-file format; this video rejects that interpretation.	needs follow-up — continued datamining of Source 2 builds and evidence of a playable project structure would confirm or refute the “full game” conclusion.

Development state	2021 HLX datamine discovery and Tyler’s reconstruction of the Half-Life: Alyx timeline.	Tyler says Valve and the Half-Life: Alyx team started pre-production on a single-player title after Alyx was announced but before it was released to the public. The codename HLX was discovered in 2021. He notes the subsequent argument over whether HLX represented a full game, an engine feature, or a save format.	References the 2021 HLX codename discovery and the later debate over whether it was a game, engine feature, or save format.	needs follow-up — 2021 Source 2 datamine references and Valve production timelines would confirm the pre-production date.

Development state	Tyler’s account of a 2020 statement by Robin Walker’s team to Geoff Keighley.	Tyler identifies the Half-Life: Alyx team as Robin Walker’s development team, which in 2020 told Geoff Keighley it was trying to get “out of the Wilderness.” He says that team’s time since then has gone into the next major single-player title, codenamed HLX.	None identified in this video.	needs follow-up — the 2020 Geoff Keighley piece would confirm the “Wilderness” quote; staffing and project assignments would confirm the HLX link.

Development state	Tyler’s play of the Deadlock build and datamined Source 2 project files.	Tyler says several Source 2 features were long attributed to Citadel, also known as Neon Prime and later Deadlock: voxel-based destruction, voxel-based hair follicles, vehicle simulation, and Xen creatures. After playing Deadlock, he says none of those features belonged to Citadel, and that references to Half-Life were eventually removed from what became Deadlock.	References his 2024 effort to predict what eventually became Deadlock; no specific earlier video is named. The change is that he now separates Deadlock assets from Half-Life assets.	needs follow-up — comparing Deadlock build strings and depots with Source 2 updates and archived Half-Life references would confirm the removal and reassignment.

Gameplay	Datamined strings from Dota 2 and Counter-Strike 2.	Datamined strings in Dota 2 and Counter-Strike 2 indicate that the character the player controls in HLX wears an HEV suit, transcribed as “H suit,” and that internal strings refer to the setting as “offworld.” Tyler cites these strings as evidence that HLX is a Half-Life game.	None identified in this video.	needs follow-up — searching current Dota 2 and Counter-Strike 2 game files for “offworld” and HEV-related strings would confirm; the transcript gives no file paths or build numbers.

Gameplay	Datamined strings from Dota 2 and Counter-Strike 2.	The same strings reportedly mention workers, entities called “STS,” “pentat tanks” (as transcribed), and feral manhacks. Tyler presents these as HLX content found inside Dota 2 and Counter-Strike 2.	None identified in this video.	needs follow-up — locating the exact string tokens in Dota 2 and Counter-Strike 2 files would confirm the names, which may differ from the auto-transcript.
36gF6eiCsqU	2024-08-04	HLX Files #0	The Half-Life 3 Leaks We’ve Been Waiting For - HLX Files #0	The-Half-Life-3-Leaks-Weve-Been-Waiting-For-HLX-Files-0-36gF6eiCsqU.en.md	10	Xen gorillas and cut Xen fauna are in development	Mixed — the Alyx reference and datamined updates support the creatures’ presence in Valve’s files, but whether they remain in active development is Tyler’s hedged inference (“at one point or even now”).	Lore	Half-Life: Alyx “zoo” level content and datamined Source 2 project updates.	Tyler says Xen gorillas are real and that Valve has developed them, at least at one point. He traces the idea to an off-hand reference in the zoo level of Half-Life: Alyx and says Valve tested gorillas alongside Xen swoopers and Xen jellyfish, creatures initially cut from Alyx that have continued to receive some form of development according to recent Source 2 project updates.	None identified in this video.	needs follow-up — Alyx asset references to Xen gorillas, swoopers, and jellyfish plus current Source 2 build strings would confirm; active development status is harder to establish.

Gameplay	Datamined Source 2 project updates.	Tyler says the datamines include “a very detailed simulation of drivable vehicles” among HLX’s features.	None identified in this video.	needs follow-up — vehicle-simulation code or strings in current Source 2 depots, plus any HLX map or entity references, would confirm.
36gF6eiCsqU	2024-08-04	HLX Files #0	The Half-Life 3 Leaks We’ve Been Waiting For - HLX Files #0	The-Half-Life-3-Leaks-Weve-Been-Waiting-For-HLX-Files-0-36gF6eiCsqU.en.md	12	Single-player, cooperative, or both remains unknown	Unclear — Tyler explicitly states there is no answer and does not cite evidence for any option.	Gameplay	Tyler’s statement of uncertainty; no artifact cited.	Tyler says it is unknown whether HLX is single-player, cooperative, or both: “it’s up in the air we don’t know.” He offers no evidence either way.	None identified in this video.	unverified — an official announcement or a reliable datamine of game-mode and player entities would resolve it.
36gF6eiCsqU	2024-08-04	HLX Files #0	The Half-Life 3 Leaks We’ve Been Waiting For - HLX Files #0	The-Half-Life-3-Leaks-Weve-Been-Waiting-For-HLX-Files-0-36gF6eiCsqU.en.md	13	Development pace suggests completion is approaching	Mixed — the architecture trend is presented as a datamine observation, but the completion-date conclusion is Tyler’s inference.	Release date	Tyler’s inference from datamined Source 2 architecture trends.	Tyler says datamined “systems architecture” appears to be slowing down while “features architecture” is speeding up. He reads that as work happening quickly and a completion date approaching “sooner rather than later.”	None identified in this video.	needs follow-up — longitudinal comparison of Source 2 depots and build activity would test the trend; no release date is given.

Development state	Tyler’s inference from the HLX datamines and the Project White Sands leak.	Tyler says that if he goes “out on a limb,” HLX “could very well be a Half-Life 3,” while stressing that he has to be careful answering. He describes it as a non-VR Half-Life game with an HEV-suited player character that has been in development for over four years.	None identified in this video.	needs follow-up — an official Valve announcement, store listing, or unambiguous shipping build would confirm or refute it.

Valve’s Up to Chicanery! - HLX Files #1	2-New-Half-Life-Games-Valves-Up-to-Chicanery-HLX-Files-1-FNNZUjkN3Qg.en.md	1	Half-Life 2 20th-anniversary testing branch	Fact — the branch is presented as an observed Steam depot/branch change rather than an announcement; the anniversary interpretation is Tyler's inference.	Development state	Steam branch tracking observed by Tyler (comparable to the SteamDB branch tracking he cites for Half-Life 1).	"Tyler reports that ""only a couple of days ago"" Valve opened ""a brand new testing Branch for halflife 2,"" ahead of the game's 20th anniversary. He notes he deliberately waited until after Thursday to judge whether it was worth reporting, because ""nine times out of 10 they're going to launch something on a Thursday"" and Thursday is Steam's lowest-traffic day. Thursday passed with no launch, so the purpose of the branch remains unknown."	None identified in this video.	needs follow-up — confirm the existence and contents of the new Half-Life 2 testing branch in Steam depot/branch records and whether any build was pushed.

Release date	SteamDB tracking of Half-Life 1 test branches and the November 2023 Half-Life anniversary update.	Tyler recaps that about a year earlier Valve had secret testing branches attached to Half-Life 1 that were caught by SteamDB; these were separate builds used to test features pre-release. In November 2023 it became clear the work was for a 25th-anniversary content drop that included a completely revamped front end and engine plus new and obscure content officially added to the build.	None identified in this video.	verified — the November 2023 Half-Life anniversary update and its contents are publicly documented.

Marketing	Official Valve anniversary releases and the Noclip documentary.	Tyler notes the Half-Life 25th anniversary was also marked by the release of a small amount of official cut content and a full-length documentary made by the people behind Noclip.	None identified in this video.	verified — both releases are publicly available.

Release date	Tyler's inference from HLX development tracking and community speculation.	"Tyler says that following recent news of the next Half-Life game, many people speculate the Half-Life 2 20th anniversary could be when Valve starts teasing the franchise's future. He concedes it ""remains possible"" but argues Valve ""very rarely is capable of adhering to even internal deadlines,"" and that although HLX has been in development at least four years, it is not far enough along to release before the end of 2024 or the first half of 2025."	None identified in this video.	unverified — would require an official Valve announcement or a shipping build.

Valve’s Up to Chicanery! - HLX Files #1	2-New-Half-Life-Games-Valves-Up-to-Chicanery-HLX-Files-1-FNNZUjkN3Qg.en.md	5	Pyro's claim of two unannounced Valve games	Mixed — the claim originates from Pyro and is explicitly labeled unsubstantiated by Tyler, while Tyler's subsequent source-checking is asserted but not shown.	Other	Pyro's reaction video to Tyler's prior HLX video, plus Tyler's own follow-up conversations with sources.	"Tyler describes a reaction video by Pyro to his previous HLX video in which Pyro said, characterized by Tyler as ""unsubstantiated,"" that they knew about Deadlock four years ago and that Valve currently had two different games in development outside of things like Counter-Strike and Deadlock. Tyler states Pyro is not a source he takes at face value, but says the remark was made a little under two weeks earlier and that he began asking around afterward and ""did learn a few things."""	Tyler's previous HLX video, which Pyro was reacting to; the video does not restate that video's specific claims beyond the reactions to them.	unverified — would require corroborating evidence of two additional Valve projects or an on-record source.

Hardware	Tyler's sourcing conversations following Pyro's claim; no named document or datamine cited.	"Tyler says that after asking around he learned the Deckard, described as Valve's next flagship VR headset, is ""still very much in production"" and that Valve still intends to ship the hardware."	None identified in this video.	needs follow-up — would be confirmed by import/transport records, certification filings, or an official Valve statement.

Development state	Tyler's accumulated datamining of HLX-related code and his prior video.	"Tyler states that HLX, as currently known, is not a VR game, and that this ""has become even clearer following the release of the last video."""	Tyler's previous HLX video, which he says made the non-VR status clearer.	unverified — would require HLX build or configuration evidence showing no VR/OpenVR requirements.

Hardware	Tyler's inference from the Deckard's continued development and the Half-Life Alyx/Index precedent.	"Tyler argues that a game built to showcase the Deckard's features ""is very much going to happen,"" by analogy with Half-Life Alyx showcasing the Valve Index. He suggests that if Pyro's claim is accurate, the second unannounced game is more than likely a VR title paired with the Deckard."	None identified in this video.	unverified — would require a Valve VR title announcement or Deckard launch lineup.

Gameplay	Long-circulating community rumor predating Half-Life Alyx's announcement; no document or datamine cited.	"Tyler recounts an old rumor from about a year before Half-Life Alyx was announced: an asymmetric multiplayer Half-Life game where one player is in VR as Alyx Vance and one player is on PC as Gordon Freeman, with the two games interacting and cooperative elements between Alyx's story and Gordon's story. He labels it ""just a rumor"" that has circulated for years."	None identified in this video.	unverified — no primary evidence presented; would require project documentation or an official reveal.

Development state	Gabe Newell's public remarks after Half-Life Alyx's launch, plus Tyler's inference from continued team activity.	"Tyler says the Half-Life Alyx team is ""deep in halflife development right now across the board,"" citing Gabe Newell's statement shortly after Alyx's launch that the team's enthusiasm and efficiency were at an all-time high even after shipping. Tyler concedes the fruits of that labor have not been seen publicly."	None identified in this video.	needs follow-up — the Newell quote is checkable; current team assignments are not.

Technology	Datamine of Valve's shipped code/tools, specifically the latest Dota 2 update's external bug-reporting configuration.	"Tyler describes internal tooling details: Half-Life assets are specifically labeled with an alien head for anything related to Xen; the ""build break master"" that checks whether the build works is depicted as Gordon Freeman with a crowbar; and the external playtester bug reporter is now publicly known because of a leak in the latest Dota 2 update that lists HLX as one of the modes within the external bug reporting system."

Other	Tyler's own account of his datamining workflow.	Tyler says he has spent the better part of three weeks going through every piece of code Valve shipped in calendar year 2024 and is nowhere near finished; he originally expected to wrap the project in two weeks. Rather than wait until October or November for one long video, he is splitting the work into parts, intending to ship a video every two weeks (later in the video stated as every two to three weeks) covering everything found up to that point.

Technology	Dota 2 update release plus Tyler's analysis of Valve's shared engine codebase across branches.	"Tyler notes the Dota 2 ""Puppet Master"" major content update and The International 2024 content update shipped the day before, meaning engine changes had to be dug through. He says Valve ""reportedly uses the same code base across all projects,"" sharing it across branches and modes keyed to each project's codename, so a large Dota 2 update means HLX-related code can surface even though Dota 2 does not use the entire HLX codebase."	None identified in this video.	needs follow-up — compare Dota 2 and HLX build strings to confirm shared code and codename-based branch separation.

Development state	Tyler's comparison of HLX-related strings across Valve builds before and after his prior video.	"Tyler says Valve responded to his previous video by ""removing and renaming pretty much everything"" he had directly reported on: the ""Xen gorilla"" has been removed completely, and ""Houndeyes"" and the ""HEV suits"" have been renamed to ""NPC monster"" and ""Burbank suits,"" respectively."	Tyler's previous HLX video, which reported the Xen gorilla, Houndeyes, and HEV suit strings; this video reports they were removed or renamed afterward.	needs follow-up — diff the relevant HLX strings across consecutive builds to confirm the removals and renames.

Development state	Tyler's analysis of Valve's public project slate and approximate headcount.	"Tyler says Valve is working on Deadlock, Counter-Strike 2, a hardware team, SteamOS and Proton, small amounts of Team Fortress 2 support, and a dedicated Half-Life 3 team of ""a few dozen people,"" against a headcount he puts at ""300 plus employees.""

Engine feature	Datamine of the Deadlock surface-attribute system, plus Tyler's comparison to the 2015 account.	According to Tyler, a surface's flash point and heat conductivity can be altered by the type of fuel attached to it — pouring gasoline on a surface changes both values.

Development state	Tyler comparing new LinkedIn profile material with the source cited in his first HLX video.	"Tyler ties the hiring evidence back to ""the person that we talked about in the very first hlx video we made,"" who stated that between 2020 and 2023 they were working on level design layouts, lighting, combat encounters, and puzzles. He frames the new LinkedIn material as reinforcing that earlier account."	HLX Files #1 (the first HLX video) — the 2020–2023 level design, lighting, combat encounter, and puzzle claim is restated without change; this video adds hiring and LinkedIn material as purported corroboration.	needs follow-up — the original source's identity and any documentation of that 2020–2023 work would be needed.

Other	Tyler's own statements in the video; no external document.	"Tyler restates that instead of one massive HLX/HL3 video he releases smaller ones periodically, since otherwise he would be datamining every day of his life and would likely publish after the game's trailer. He says these are findings from the last month and a half, that he is in the middle of moving (move-out date Halloween 2024), and that datamining and research time is reduced until then, after which he will resume full-time. He also proposes live datamining streams on Twitch and YouTube, noting that with Deadlock now public he can ""dig through that code publicly without any threat of being in trouble with valve legal."""

Development state	Datamine of the latest Dota 2 update's shipped files.	"Tyler says that in the latest Dota 2 update — the one that added the bird — ""somebody screwed up and shipped the symbols of Arty."" He counts 21 `.h` files (not `.pdb` files), describing them as build files that are ""as close as you can get to the source code without it actually being source code,"" exposing class names, function names, and variable names.

Development state	The Final Hours of Half-Life: Alyx plus the newly datamined Arty `.h` files.	Tyler explains that Arty was a cancelled Valve game developed after the cancellation of Left 4 Dead 3, while Valve waited for Source 2 to become feature-complete. He describes it as an entirely voxel-based engine with player destruction, akin to a basic immersive sim with large procedural destruction potential, and says the only prior evidence came from The Final Hours of Half-Life: Alyx — story treatments, screenshots, and general developer descriptions.	References prior community knowledge of Arty from The Final Hours of Half-Life: Alyx; the new files greatly expand what is known.	needs follow-up — would require cross-checking the `.h` file contents against the Final Hours descriptions.

Gameplay	Tyler's inference from Source 2 voxel code and the Arty file leak.	"Tyler says the community previously speculated that voxel work in Source 2 was for Neon Prime, but concludes ""it had to do with HLX"" and that Half-Life 3 ""is going to have voxel based destruction in some form."" He argues Valve would reuse Arty's existing voxel technology rather than rewrite it."	Explicitly revisits the earlier community claim that Source 2 voxel work was for Neon Prime and reverses that attribution.	needs follow-up — would require HLX-specific voxel destruction code or assets, not shared engine tech.

Development state	Datamine of Arty `.h` files shipped in a Dota 2 update.	Tyler says the leaked files include NPC spawners, gun logic, game mode info, and multiplayer logic, and that these systems from the old game are being ported into the modern Source 2 engine. He specifically names vehicle simulation, buoyancy simulation, fluid simulation, and voxel destructibility as systems previously assumed novel to Half-Life 3 that appear to have originated in Arty.

Gameplay	Tyler's analysis of datamined systems and prior HLX reporting.	"Tyler says Valve is pushing ""physical fidelity"" rather than graphical fidelity, simulating many systems independently so they can interact, and describes the result as resembling a next-generation immersive sim. He says Half-Life 3 is not an immersive sim at its core but will have more immersive-sim elements than prior Half-Life games, citing the Quest NPC system, procedural generation, and side-level designs. He rejects the open-world reading and describes the structure as ""open linear,"" closer to Uncharted 4 than Fallout."	Addresses earlier community speculation that the game would be open world, which he says was a misunderstanding.	needs follow-up — would require map/level structure data or official material showing the quest and side-level systems.

Hardware	Tyler's inference from Valve's historical performance record and the Steam Deck.	"Tyler raises the computer cost of running the game at a good frame rate, notes that Valve's games have historically run well from Half-Life 1 onward, and says Half-Life: Alyx now runs on a ""toaster"" while Half-Life 2 ran on almost anything.

Engine feature	Tyler's account of Source 2 file datamining (VPulse files) and observation of Counter-Strike 2 and Dota 2.	"Tyler describes the ""Pulse"" scripting system as a flowchart tool comparable to Unreal Engine 4 Blueprints that lets developers wire game systems, NPCs, entities, and AI rules together. He says the files are called VPulse, that the system is partially used in Counter-Strike 2 and Dota 2, and that the code exists in Source 2 but no public user interface allows development with it.

Technology	Datamine of the latest Deadlock update localization strings.	"The latest Deadlock update reportedly added localization strings for surface attributes tied to flammability: ""heat aura"" (how close an object must be to a surface to be heated), ""burn damage"" (how much the surface changes fire damage dealt on it), and ""instant ignition"" (whether entities touching the surface ignite immediately).

I don't know all the factors that will affect this system,"" and the gravity-gun example is his illustration."	Gameplay	Tyler's inference from the Deadlock surface-attribute strings and Source 2 physics capabilities.	Tyler connects the flammability attributes to a broader system where liquids and materials coat objects and change both the object and its surroundings, described as a more sophisticated version of Portal 2's gels: gasoline or enemy blood can cover level geometry, and a flammable object can be ignited and launched with the gravity gun for extra damage. He notes that water, blood, object temperature, and flammability all interact, and frames it as an attempt to recreate the E3 2003 Half-Life 2 physics reaction.

Technology	Pastebin datamine published by Gabe Follower (Maxim), compared against Tyler's notes.	Tyler credits Gabe Follower (Maxim) with conducting his own datamines and publishing them on Pastebin, and says comparing notes surfaced items he had not covered.

Tyler argues that a complete save/load rewrite does not change how the game plays and is the kind of work done at the end of development, comparable to FSR implementation.

Engine feature	Datamine of surface-property/audio strings and Tyler's analysis.	Absorption coefficients in code refer to sound absorption, not liquid/material absorption — the dampening effect of materials on sound waves. Previously separate surface attributes were set per frequency band (high, mid, low); now sound absorption, scattering, and transmission based on material properties are refactored into one cleaner, cheaper, more optimized system. Tyler notes absorption and transmission no longer use separate frequency band ranges.	"Earlier episodes' discussion of the surface property system is referenced (""we have discussed at length""), but no episode is named."	needs follow-up — comparing old and new surface property definitions in engine files/builds would confirm the merge of frequency-band attributes.

"New flags cover hit groups, damage, kill, and triggers that change behavior on death, including ""destruction death behavior"" with options do not kill, kill, gib, or remove, plus ""MC_B keep loaded ammo."" Tyler says these come from the latest Counter-Strike update but are unrelated to Counter-Strike; they enable Doom-style destructible enemies whose body parts can be shot off, damage can trigger map events, and corpses can still react to later damage. He stresses the functions have been evidenced for about two years and this is a tool cleanup/refactor, not their introduction."

"A small new icon labeled ""science assets"" appeared in the Counter-Strike update of October 15, used by Valve's tools to denote a group of assets marked ""science."" Tyler says its meaning is completely unknown and rejects the ""Portal 3"" reading.

"Tyler argues the announcements ""have not ended,"" reasoning that if Valve had announced a console, a VR headset, a controller, and a full-blown Half-Life sequel on the same day, nobody would have been talking about the hardware.

"Tyler pushes back on the theory, circulating on the Half-Life subreddit, that the Half-Life project would be announced around November 18 or 19 because of a gap in Steam events, and on claims that a Steam event was rescheduled to make room for a large software announcement. He states that Steam events, sales, and fests have no bearing on the announcement or release of Valve products, that ""November 18th is a rumor,"" that anyone claiming it as the exact date likely got it from someone who got it from Reddit, and that there is nothing directly suggesting any specific date."

"Tyler reads from a Half-Life subreddit post by Jason Schreier, who wrote: ""As some of you may know, I report on the video games industry and often break news based on inside information. As some of you may have seen, thanks to Tyler McVicker and other hype merchants, I predicted at the beginning of this year that a new Half-Life would be announced."" Schreier continued that his predictions are explicitly not based on inside information, as stated each year on his Triple Click podcast, and that ""I have no idea whether or not Half-Life is being announced this year."" Asked why he clarified, Schreier said he takes his track record of accuracy seriously and did not want people saying he got something wrong when he never reported it. Asked what prompted the prediction, he cited the ending of Half-Life Alyx making clear Valve wants to keep going and the roughly six years since that game, about as long as big games take."

Development state	Datamine of the November 8 updates, cross-referenced with Valve's statement to Upload VR.	"Responding to Valve's statement that no demos are in development for its hardware, Tyler concludes ""the code name TF is not a demo,"" repeated twice, and notes TF received a lot of attention in the updates datamined on the 8th of November.

He also closes by saying this may very well be the final episode of the HLX Files, noting he has followed the Half-Life 3 story since a July 2011 video about the future of Half-Life 2: Episode 3, made when he was 14 and he is now 28."

Technology	Tyler's analysis of how Valve develops Source 2.	Source 2 began around 2009, near the time of Left 4 Dead 2, and evolved from what Tyler calls an unfinished mess partly to blame for Valve's dark times into an easy-to-use engine. Valve does not fork Source 2 per project: engine code pulled to build any one game is the same across all titles, so a system built for Deadlock can be adopted by Dota with little work compared with porting between branches. The stated downside is that features built for an unannounced project are eventually folded into the base engine of shipped games.	None identified in this video.	needs follow-up — comparing engine depot or branch structure across shipped Source 2 titles would confirm or refute the shared-code claim.

Technology	Tyler's description of his own research method.	Because Valve's Source 2 multiplayer titles are actively updated, comparing each patch of Dota 2, Deadlock and Counter-Strike 2 against its previous version exposes newly added engine functionality; cross-referencing across the library over months or years yields a technical picture of internal Valve projects. Tyler says this is how HLX became known, and that the series will cover every significant HLX finding from the previous five years, all derived from publicly available Valve software and patches rather than internal sources, leaks or rumors.	None identified in this video.	needs follow-up — the method is reproducible in principle by diffing public builds, though the interpretive conclusions are not directly checkable.

Tyler defines VData as designer-driven gameplay data that lets designers add or modify mechanics without code, noting that post-2021 Source 2 games are heavily VData-driven, including Aperture Desk Job, Counter-Strike 2, Deadlock and Dota in some instances. FGD (Forge Game Data) is a plain-text entity definition file used by modeldoc, the Pulse editor, VData and Hammer, listing available entities (NPC, item, weapon types, physics props) and their customizable flags. I/O are entity commands used by level designers as basic logic in the map editor. Schemas are class descriptions exposing systems, properties and tools in human-readable form.

"Quoting Geoff Keighley's ""The Final Hours of Half-Life: Alyx,"" Tyler recounts that in January 2019 Eric Wolpaw, on an elevator ride to the Valve offices, suggested to artist Jim Murray (described as a British comic book artist known for work on 2000 AD and Judge Dredd) that the GMan take the player to the end of Half-Life 2: Episode Two and save Eli's life; Wolpaw first called the idea ridiculous, then allowed it might work. On January 21, 2019 the four-person story team pitched the retcon to the larger team in the fishbowl room, framing it as option A with an option B ready if rejected; the pitch was received as a bold idea that added levity against the game's horror elements."

Tyler describes the Gabe Newell approval step and its origin: in the final months of Episode Two production in 2007 the team planned to end on a gag with Lamarr, Kleiner's pet headcrab, floating in orbit outside the White Forest rocket, but Newell wanted a bigger shock and a major character death to pay off in Episode Three.

Business/legal	"""The Final Hours of Half-Life: Alyx,"" quoted in the video; Index pricing."	The plan had been to ship Half-Life: Alyx alongside Valve's Index headset, but the new narrative and art requirements — rebuilding the White Forest base from Episode Two and creating three new character models (an older Eli Vance, Dog, and Gordon Freeman) for a post-credits tease — made a joint launch untenable unless Index slipped six months or more.

In an October 9, 2020 update to Artifact Foundry (the short-lived Artifact 2.0), the box creature test model used across Source 2 games for animation and rendering testing had an HLX-specific animgraph baked in, indicating animations were being attached to the model for testing under the HLX codename.

Engine feature	Comparison of 2021 Sandbox builds with current Source 2 tooling.	Voxel-based destruction and voxel geometry, once speculated to be part of HLX, are not part of it. Tyler says that even if Valve experimented with them when they were first found in 2021, they were never included in the Half-Life tool set in Hammer and have seen no real updates since at least late 2021. The `create_iso_surface` command in one of the original 2021 Sandbox builds is how Hammer refers to voxels, and that command is absent from current Source 2 builds.

Gameplay	Valve's public statements, Source 2 tooling comparison since Alyx, and Tyler's analysis.	"Tyler argues HLX is not VR: Valve has gone on record multiple times saying it wanted to make a non-VR Half-Life game after finishing Half-Life: Alyx; HLX has significant drivable-vehicle functionality and Super Mario Galaxy-style gravity shifting, both uncomfortable to reproduce in VR and contrary to Valve's stated ""never move the player"" philosophy; there have been no VR improvements to Source 2 since Alyx; and Alyx's TAA-based anti-aliasing does not work well in VR."

Gameplay	Inspection of Hammer limits and Source 2 lighting systems, plus Tyler's analysis.	"Tyler rejects the open-world reading on technical grounds: Hammer's walk limit is still 16,384 units, tiny relative to an open-world map; Source 2's baked light maps have been overhauled multiple times since Alyx and remain central to its optimization, with no traditional global illumination; although HLX appears to support ray tracing in the tools, Source 2 is a baked-lightmap engine first; Neon Prime was lit mostly by dynamic lighting and light probes, and Deadlock introduced distance fields but still has only baked indirect lighting. At most HLX is ""open linear,"" comparable to Doom 2016's Foundry level or open-ended Uncharted 4 levels."	None identified in this video.	needs follow-up — map compilation limits and lighting documentation would confirm the technical premises; the level-design conclusion is not directly testable.

Tyler describes vehicle configuration options: whether exits are allowed midair or when both sides of the vehicle are blocked, and a parameter for the maximum speed at which a player can enter or exit a moving vehicle. Vehicles can be overturned or flipped onto their heads similarly to Half-Life 2, wheels are highly customizable and can emit smoke under friction, and passenger use can be allowed or disallowed. Vehicles have separate hit groups — driver, driver-side entry, passenger, passenger-side entry, rear entry, front entry, and top entry — which Tyler says exist so occupants can still take damage; he deduces that drivers and passengers can be hurt while the vehicle is moving. Depending on vehicle type, vehicles may have rear, front, and top entries, and enemies can seemingly enter vehicles.	None identified in this video.	needs follow-up — inspect the vehicle schema for exit-blocking, entry-speed, rollover, wheel, passenger, and hit-group fields, and test occupant damage in-engine.

Gameplay	Datamine of Source 2 NPC animation and vehicle-related parameter lists.	"Tyler lists possible NPC animation parameters, from which he says NPCs can be stunned, play a death animation based on the final hit location, react to an attacker's strength, open doors by pressing the handle, have a flight speed (which he says confirms flying enemies), detect enemies while inside vehicles, and use melee weapons while in vehicles. He says it is unknown whether enemies can actually enter the player's vehicles or whether NPCs will fight each other inside a vehicle driven by an NPC or the player. He states this does not suggest a co-op system and that HLX is ""a single-player game as far as we understand."""

Gameplay	HLX hint-node datamine (`combine sniping position`); Tyler's analysis.	"Combine snipers are likely to return. Tyler presumes that, unlike Half-Life 2 snipers, they will take part in the active battlefield rather than only hiding in windows and being vulnerable to grenades. The hint node ""combine sniping position"" is a dynamic position, allowing level designers to define multiple positions a sniper can move between so it is not pinned to one location and can move with active combat."

Lore	Half-Life 2-era Overwatch/public-address dialogue quoted by Tyler; community speculation on Combine origins.	"Tyler separates the ""off-world"" from the Xen border world and notes heavy speculation that the off-world is where the Combine originate. He supports the concept's existence with Overwatch announcements from the games, quoting lines about rule-breaking Civil Protection officers facing ""permanent off-world assignment"" and citizens facing ""permanent off-world relocation."""

Valve has expanded Half-Life: Alyx's limited destructible mechanics (shooting a Combine grunt's backpack to make it explode, shooting off antlion legs to make them vulnerable) into a full game system. The destructible part system allows every body part to be destroyed — legs, arms, head, chest, gear, and so on.

Engine feature	Datamined Source 2 engine files described by Tyler, including observation of recent file removals.	"NPCs can enter a temporary ragdoll state when hit by a vehicle and do not necessarily die, unlike the Hunters in Episode 2; vehicle damage must pass a threshold to kill. The duration of the temporary ragdoll scales with damage — a crate causes a short ragdoll, a car much longer.

Engine feature	Datamine of the Deadlock update of 2026-02-05.	The new particle-based volumetric smoke system exposes three interaction types — emission, sink, and repel — and two creation types — continuous injection from particles and instant impulse on each particle event. Particle parameters listed include position, velocity, radius, density, temperature, fuel source, dust, lifespan, magnitude, kill radius, and falloff. Tyler describes these as protobufs for particle-based volumetric smoke, similar to the CS2 system but game-specific and particle-driven.

Tyler notes that many people read the cutscene/choreography tooling as evidence the game is much further behind than previously thought, then argues the opposite: Half-Life 2 leaked about a year before release with no choreography work completed — only stopgap cutscenes and voice acting — and animated first-person choreography was not shown until E3 2004.

Engine feature	Source 2 animation tooling and Animgraph 2 file definitions.	Tyler says Animgraph 2 is the new animation resolve system intended to replace Animgraph 1, which was not networked efficiently in multiplayer titles and caused large bandwidth consumption. Instead of one Animgraph file containing animation and skeleton data in the VModel, Animgraph 2 stores animations in separate `VNM clip` files and skeletons in `VNM skull` files, so they no longer need to be present in the VModel. Skeletons support bone-level LOD, with significantly fewer bones at low LOD levels. Graphs can have multiple variations: core graphs contain purely resolve logic, while specified variations can reference overridden animation clips and overrideable graphs. The state-machine resolve is completely different and lacks some Animgraph 1 features for optimization.

It can create an AnimGraph 2 graph, convert a render mesh file into an AnimGraph 2 skeleton, and convert all animation sequences referenced in a model into Animgraph 2 clips. The clip creator also respects the subtractions used to create additive animations and anim events, converting them to a new legacy format. The same update adds AnimGraph 2 list and skeleton list support directly into Model Doc so newly authored Source 2 models can reference Animgraph 2 resources.

Development state	Tyler's analysis of Valve's VR software strategy and platform requirements.	Tyler argues Valve is not creating a new flagship VR game, instead porting a six-year-old VR title and asking third-party developers to port software to an ARM-compatible Linux environment. He says this is harder than porting from Quest 3 because it is a different environment, and that VR is fragmented across PC VR, Quest, Steam Frame, and PSVR, with Valve adding another segment.

"Tyler describes the held-object system's evolution as rules added to items the player holds: some objects cannot be broken until they are set on fire, and whether an object catches fire may depend on the ignition temperature of its materials and whether it is impregnated with oil. He also reports rules requiring an item to be in hand for a certain amount of time before it can be broken, and calls the physics system ""really cool."""	None identified in this video.	needs follow-up — the item rule definitions and material ignition properties would confirm the mechanics and their dependencies.

Engine feature	"Datamine of the three engine updates, ""Half-Life Hammer"" feature-set strings, plus Tyler's explanation of Source 2 tooling."	"Tyler explains that Valve does not create separate engine branches for its projects — there is no ""version of Deadlock on Source 2,"" Deadlock simply runs on Source 2 — so tools adapt through feature sets chosen when Source 2 tools launch. Half-Life is one such feature set, and he says it was recently updated to allow completely recalculating surface graphs from scratch when building a map, with surface graphs tied to precipitation effects and their reflection on specific surfaces."	None identified in this video.	needs follow-up — launching the Source 2 tools with the Half-Life feature set would confirm the surface-graph rebuild option.

Engine feature	"Valve's ""Valve's Approach to an Open and Flexible Audio Engine"" talk at the Game Sound Convention, as described by Tyler."	"Tyler says the fog, rain, and wind systems are ""incredibly detailed"" and constantly refined, and that in the convention talk many sound operators related to precipitation — in this case rain — change meaning depending on where the rain falls, the materials it falls on, and whether the player is indoors or outdoors."	None identified in this video.	needs follow-up — the talk recording or slides would confirm the rain-operator parameters and their material and indoor/outdoor conditions.

Development state	Tyler's analysis of the audio talk and the datamined strings shared between HLX and Deadlock.	Tyler argues the talk seems to be trying to hide that Valve is demonstrating features created for HLX by directly porting them to Deadlock. As evidence he cites details a fast-paced competitive game would not need: trains that fly in the air, headcrab sounds, and rainfall audio far more detailed than Deadlock requires, especially since Deadlock had no rain at the time of writing.	None identified in this video.	unverified — an HLX build, a Valve statement, or Deadlock shipping these features would test the porting claim.

Engine feature	"Datamine of the three engine updates, ""HLX Basic Projectile Emitter Helper"" strings and tooltip."	"A second direct HLX link is the ""HLX Basic Projectile Emitter Helper,"" another Hammer support tool that visualizes projectile release randomization from a base seed inside Hammer. Tyler says the tooltip explicitly states that the randomization can be visualized and that each load will produce something new, and he notes the emissions look like particles even though the tool is a projectile emitter."	None identified in this video.	needs follow-up — the helper's seed and randomization parameters would confirm the behavior it previews.

Engine feature	Kayla's datamine of the Source Filmmaker 2 updates, quoted by Tyler, plus the HLX tracking board.	"Tyler quotes dataminer Kayla from his Discord server, who reported that the last two updates changed the file Source Filmmaker uses to classify bones by body part, ""SFM default animation groups,"" to add bone names for a new rig called Gen Biped (generic biped). Deadlock, Dota 2, and CS2 do not use those bone names in their released assets, and Kayla says the names are commonly used by MetaHuman-compatible tools, though she is ""not entirely sure."" Tyler ties this to the DNA bones and DNA-format animations he has been tracking on the HLX Miro board, notes SFM 2 is external animation tooling, and concludes ""This is for HLX"" rather than Deadlock."	"Tyler explicitly references ""the last video"" for the DNA bones; the new element is the SFM 2 bone-classification change and the Gen Biped rig."	needs follow-up — the SFM default animation groups file and the Gen Biped bone list can be re-read, and comparing the names against MetaHuman rigs would test the compatibility claim.

Development state	Public Source 2 commit numbers in CS2, Deadlock, and Dota 2 updates, plotted by Tyler.	Tyler explains that every Valve update carries a public commit number tied to internal commits rather than public pushes, so the total reflects overall studio productivity, though individual commits vary enormously in importance. His graph of internal commits since Rush Hour, City Never Sleeps, and Inside the Trove of Terror shows sharp growth, which he compares with the productivity increase before Half-Life: Alyx was announced. He notes Deadlock has been making incremental public changes for about a year and a half and has been in internal development since 2018.	None identified in this video.	needs follow-up — reproducing the commit-number chart from the public builds would confirm the trend, though not its cause.

Development state	Tyler's account of references to AI tooling in Valve's development since 2024.	"Responding to the expected ""they switched to Claude Code"" reaction, Tyler says there have been direct references to AI use in Valve's development since 2024, that this is nothing new, and that it is unknown how many people at Valve use AI. He does not think the recent commit growth is only due to more programming agents because the practice has been going on for some time."	None identified in this video.	needs follow-up — the referenced 2024 material would need to be identified, and commit composition is not public.

Release date	Tyler's inference from the commit-number trend and development signals.	"Tyler says he thinks HLX is ""currently in intensive development mode"" but does not believe it will be announced in 2026, a forecast he says he left open in the original cut of the video before viewer complaints. He acknowledges he could be wrong and says viewers can laugh at him if so, but repeats that he does not believe it will happen this calendar year."	Tyler says the original version of this video left the question open and that he is now stating a view after feedback; no earlier episode is cited.	unverified — an official announcement before the end of 2026 would refute it.

Other	Tyler's account in the post-credits segment.	"In the post-credits segment Tyler proposes interviewing Mike Morasky on the channel and says they almost arranged one, but someone intervened with the comment, ""we have a strange relationship with Valve."" He frames it as something to try again."	None identified in this video.	unverified — only a published interview or a statement from the parties involved would confirm the account.
