AI agents rebuild a shooter's source code in three months
What happened
A project on the Hacker News front page on October 11 used AI agents to decompile a first-person shooter. Over three months the team rebuilt the game's C++ source, covering 99% of functions, with 83% of them byte-exact. Early generated code ran but was semantically wrong, so the team switched to the original compiler and byte-match checks, refreshing instructions hourly to stop agents drifting off task or editing the verification scripts. The headline says 500B tokens; the author estimates 600 to 700 billion.

Over three months a team used AI agents to rebuild the C++ source of a first-person shooter, covering 99% of functions, with 83% matching byte-for-byte. Early code ran but was semantically wrong, so the team switched to the original compiler and byte-match checks, refreshing instructions hourly and blocking agents from drifting off task or editing the verification scripts. The author estimates real usage at 600-700 billion tokens, calls the project done, and will keep the code private.
