Developer uses AI agents to reconstruct Modern Warfare 2's source code in C++
Maurice Heumann spent three months and an estimated 600-700 billion AI tokens using Claude and Codex agents to decompile and rebuild the C++ source code of 2009's Call of Duty: Modern Warfare 2. He reports 99% of the game's functions have been recreated, with 83% matching the original code, and says the game is now fully playable. Two earlier blog posts and a video of the project have since been taken down following a copyright report from the rights holder.
