The full source code for the MGS2 HD remaster (Vita/Xbox 360 ports by Armature Studio) leaked on 4chan as of May 1, 2026.
Key Takeaways
The leak covers the 2011 HD remaster’s PlayStation Vita and Xbox 360 port code, developed by support studio Armature, not the original PS2 build.
Conflicting reports: one source claims 30GB of uncompressed unused assets included; Kotaku reports the leak is code-only with no assets.
Unused material and cut content may be present, opening potential for preservation projects and mods similar to Zelda’s Ship of Harkinian.
Master Collection Volume 1 remains the current recommended way to play MGS2; decompilation work is just beginning.
Hacker News Comment Review
Authenticity debate surfaced immediately, with one commenter raising whether this could be an AI-assisted decompilation reconstruction rather than a genuine internal leak.
Evidence pointing toward a real leak: original Japanese comments describing cut content and scrapped game logic are present in the code, which would be hard to fabricate via decompilation agents.
Notable Comments
@AnotherGoodName: Raises plausible alternative – LLM-assisted decompilation can produce compilable, structured source from machine code, making synthetic leaks hard to rule out without internal markers.
@bigyabai: Original Japanese comments describing cut content and scrapped logic are “probably” confirmation this is a genuine internal leak.
