GoKawiilDevelopers use AI agents to decompile a first-person shooter over three months
A developer and community collaborators spent roughly three months and 500 billion tokens directing AI coding agents to reconstruct a popular first-person shooter's source code in C++. The project used Claude Code and Codex CLI subscriptions, switching between multiple models including Sonnet 5 and Opus 5.5, and tracked progress through GitHub issues. The author removed two earlier blog posts about the project, citing pressure from the game's corporate rights holder.
