The source code for multiple versions of Metal Gear Solid 2 has reportedly leaked online via a 4chan thread. The files, dated March 4, 2007, include code for HD ports on PlayStation 3, Xbox 360, and PlayStation Vita, as well as unreleased versions for PC and Nintendo Wii of Metal Gear Solid 2: Substance. The leak surfaced on May 1, 2026, prompting speculation about its authenticity and origin.
An anonymous individual uploaded the source code to a thread on 4chan's /vr/ board, with a partial download link on Pixeldrain. The files total 155.8 megabytes and contain no game assets, focusing solely on code. Initial screenshots and comments from users, including a post by Vinícius Medeiros on X stating, 'Metal Gear Solid 2 source code (HD version) just leaked alongside raw uncompressed assets. Yes it's real, I never thought this would happen,' suggest the leak may be legitimate despite its 4chan origin, which typically invites skepticism. A later thread appeared on the /v/ board.
