Turn a single-player game into co-op with an agent
A poster shares a repo whose instructions let Claude Code revive or build co-op mods for games; it lists Deus Ex as released and Ocarina of Time as fully synced.
Done with Claude Code
What they did
A poster shared a repo with instructions for coding agents. You paste two lines naming a game. The agent either repairs a broken co-op mod or reverse engineers the game to add one. It then tests with real game clients and opens a draft change for review.
How it went
The post says Deus Ex co-op is released and Ocarina of Time is fully synced. Several other games and 230+ mods are listed as in progress or gaps.
Worth knowing
Some games take far more agent hours than others. The rules require owning the game, a copy per player, and no touching anti-cheat or others' online play.
