But nothing could have prepared us for this weekend\u2019s \u201cterarelease\u201d encompassing more than 12TB of content related to seemingly every title available on Steam between 2003 to 2013.<\/p>\n<p>What\u2019s being sold as an \u201cas-complete-as-possible \u2026 content server dump\u201d of Steam\u2019s defunct \u201cSteam2\u201d server architecture from that time period is now circulating around via a BitTorrent tracker that Valve seems unlikely to ever completely purge from the Internet. The massive collection includes <a href=\"https:\/\/steam2-db.pages.dev\/\" rel=\"nofollow noopener\" target=\"_blank\">thousands of \u201cdepots\u201d<\/a> representing what seems to be every version of every game uploaded to those old Steam2 servers. That includes public release builds, of course, but in many cases also covers previously unseen pre-release, prototype, and playtest versions of popular titles published by Valve and third-party Steam publishers.<\/p>\n<p>Steam2: Electric Boogaloo<\/p>\n<p>The reason this weekend\u2019s leaked content cuts off abruptly in 2013 is because that\u2019s when Valve <a href=\"https:\/\/developer.valvesoftware.com\/wiki\/SteamPipe\" rel=\"nofollow noopener\" target=\"_blank\">updated its content distribution system from \u201cSteam2\u201d to the current SteamPipe system<\/a>. In moving from a proprietary file distribution format to standard HTTP file trees, the new system <a href=\"https:\/\/www.pcgamesn.com\/tf2\/what-steampipe\" rel=\"nofollow noopener\" target=\"_blank\">removed various update approval bottlenecks<\/a> on Valve\u2019s end and streamlined update and patch downloads so they only reflected file differentials.<\/p>\n<p>Publicly accessible early versions of some games released before this SteamPipe transition <a href=\"https:\/\/www.reddit.com\/r\/DataHoarder\/comments\/1dwx1s8\/does_anyone_have_steam_installs_from_before\/\" rel=\"nofollow noopener\" target=\"_blank\">had been considered lost content by archivists<\/a>, no longer accessible from Valve itself and living on only as local downloads on aging machines. Apparently all that content wasn\u2019t as lost as many thought, though. Longtime Valve watcher and data miner Gabe Follower (<a href=\"https:\/\/arstechnica.com\/gaming\/2024\/05\/leaks-from-valves-deadlock-look-like-a-pressed-sandwich-of-every-game-around\/\" rel=\"nofollow noopener\" target=\"_blank\">previously<\/a>) <a href=\"https:\/\/x.com\/gabefollower\/status\/2093847346245230797\" rel=\"nofollow\">wrote on social media this weekend<\/a> that he had \u201cverified that everything in Steam2 Teraleak was obtained via a publicly accessible [API] endpoint. It\u2019s Valve\u2019s fault\u2026\u201d<\/p>\n<p>Spanish-language <a href=\"https:\/\/www.youtube.com\/@Scolcer\" rel=\"nofollow noopener\" target=\"_blank\">Valve streamer and analyst<\/a> Scolcer <a href=\"https:\/\/x.com\/scolcer_\/status\/2093858629967360017\" rel=\"nofollow\">also said on social media<\/a> (via machine translation) that the teraleak was \u201cobtained from a site that was 100% accessible to the public. It was there for everyone to download. No passwords. Nothing. Hidden in plain sight, but with no protection whatsoever.\u201d<\/p>\n<\/p>\n<p>\n      Gabe Follower walks us through some of what\u2019s been found in the teraleak thus far.<\/p>\n<p>What\u2019s unclear right now if that API and publicly available Steam2 server content were accessed recently or if this weekend\u2019s leak represents content that was privately archived before the 2013 server transition and is just now being made public. \u201cIt could more-so be a collection of different people that knew about it and accumulated whatever people had downloaded back then into this massive archive,\u201d said The One Epicplayer, a moderator on the Valve Cut Content (VCC) Discord, which has long followed Valve betas and leaks.<\/p>\n<p>\u201cI haven\u2019t been filled in on the full details but my suspicion is that these depot [files] were downloaded a long time ago and sat in a private collection,\u201d CrazyBubba, another VCC Discord moderator, told Ars. \u201cThere were a lot of leaks a few years back and many folks hoarded files for years. \u2026 historically there have been issues with people lording content over other members.\u201d<\/p>\n<p>A readme file included with the leak offers \u201cwarm n good wishes to all hoarders who had stuff from this collection &lt;3\u2033 and encourages users to mirror and share it as widely as possible. On the VCC Discord, a user purporting to be the original uploader of the teraleak (who offered screenshots of a 22TB server upload log among their evidence) wrote that \u201cgetting this out really took a significant amount of effort from me and I would like it if it didn\u2019t go to waste.\u201d<\/p>\n<p>Now you\u2019re thinking with old Portals<\/p>\n<p>Regardless of the hows and whys of the leak, eager gaming communities have wasted no time in digging through the \u201cteraleak\u201d <a href=\"https:\/\/hiddenpalace.org\/Steam2_Content_Server\" rel=\"nofollow noopener\" target=\"_blank\">in search of cut content and playable early versions<\/a> of many now-classic PC games.<\/p>\n<p>Multiple playable pre-release versions of Portal 2 contain some of the most intriguing cut content discovered so far. Already, teraleak diggers are finding deleted sequences including <a href=\"https:\/\/x.com\/TheJeremy__\/status\/2093817196744933745\" rel=\"nofollow\">new dialogue from GLaDOS<\/a>\u00a0and <a href=\"https:\/\/www.youtube.com\/watch?v=5C7zqm7t3v4\" rel=\"nofollow noopener\" target=\"_blank\">Aperture CEO Cave Johnson\u2019s consciousness trapped in a cube<\/a> (\u201cMy life is torture, please kill me,\u201d a scratch track version of Johnson says in cut dialogue that was <a href=\"https:\/\/combineoverwiki.net\/wiki\/User:Sandvich18\/List_of_scenes_in_Portal_2\/The_Reunion\" rel=\"nofollow noopener\" target=\"_blank\">previously seen in a text file included with the game<\/a>). The early development version also apparently includes fun features like <a href=\"https:\/\/x.com\/gabefollower\/status\/2093836902835093984\" rel=\"nofollow\">perfectly circular portals<\/a>, an <a href=\"https:\/\/x.com\/scolcer_\/status\/2094026326202024358\" rel=\"nofollow\">adhesive gel and slow-motion guns<\/a>, and <a href=\"https:\/\/x.com\/HL_Alyx_NoVR\/status\/2093813696602533978\" rel=\"nofollow\">an interesting looking weapon model<\/a> that was <a href=\"https:\/\/combineoverwiki.net\/wiki\/Unidentified_Half-Life_2:_Episode_Three_weapon\" rel=\"nofollow noopener\" target=\"_blank\">previously seen<\/a> in <a href=\"https:\/\/arstechnica.com\/gaming\/2024\/11\/newell-says-he-was-stumped-on-how-to-finish-half-life-2-episode-3\/\" rel=\"nofollow noopener\" target=\"_blank\">official Valve documentary footage<\/a> of the unreleased Half-Life 2: Episode 3.<\/p>\n<\/p>\n<p>\n      \u201cMy life is torture, please kill me\u201d<\/p>\n<p>While there are no playable \u201cHalf-Life 3 confirmed\u201d depots included in the leak, data trawlers have <a href=\"https:\/\/x.com\/scolcer_\/status\/2093884437750587773\" rel=\"nofollow\">reportedly found some \u201cep3\u201d data files<\/a> seemingly related to <a href=\"https:\/\/arstechnica.com\/gaming\/2016\/05\/celebrating-ten-years-of-half-life-2-episode-3-not-coming-out\/\" rel=\"nofollow noopener\" target=\"_blank\">the perpetually delayed expansion<\/a>.

And while that list won\u2019t contain the early versions of those games that stayed on developers\u2019 local computers and office networks, the playtest versions that were often uploaded to Valve\u2019s servers near release often still contain some interesting content.<\/p>\n<p dir=\"ltr\" lang=\"es\">Habilidades eliminadas de la beta de Portal 2:<\/p>\n<p>-Gel adhesivo<br \/>-C\u00e1mara lenta<br \/>-El weaponizer de Half-Life 2: Episodio 3 probablemente se usaba de placeholder para el arma de pintura <a href=\"https:\/\/t.co\/qQgfS76EXs\" rel=\"nofollow\">pic.twitter.com\/qQgfS76EXs<\/a><\/p>\n<p>\u2014 Scolcer (@scolcer_) <a href=\"https:\/\/x.com\/scolcer_\/status\/2094026326202024358?ref_src=twsrc%5Etfw\" rel=\"nofollow\">August 30, 2026<\/a><\/p>\n<p>Even though this weekend\u2019s leak doesn\u2019t contain any games released in the last 13 years, the major publishers affected likely still won\u2019t be too happy that Valve\u2019s lax security apparently led to their previously unreleased early work product leaking out to the public (not to mention the piracy implications of releasing such a complete, if outdated, collection of Steam content). The teraleak highlights how Valve\u2019s own servers now serve as an extremely high-profile single point of failure for the security of a massive chunk of PC game development history.<\/p>\n<p>Some are worried about the legal implications of handling such large quantities of previously private game builds as well. \u201cThat archive contains a significant amount of 3rd party content, meaning we are dealing with a dramatically more dangerous situation than if it were just some Valve builds,\u201d longtime Valve watcher Tyler McVicker <a href=\"https:\/\/x.com\/Tyler_McV\/status\/2093848662895902856\" rel=\"nofollow\">wrote on social media<\/a>. \u201cDon\u2019t touch it, it\u2019s HOT.
