Co-op Anything

NewgamesOpen source

Co-op Anything lets you point your AI coding agent at a single-player game and have it build or revive a co-op mod, so you can play it with friends online or split-screen. The project gives the agent a step-by-step method for working out what has to be synced between players (the story, enemies, the world, items and players seeing each other) and testing it. Its website is a searchable directory of every co-op mod made this way, with player ratings, how much of each game works in co-op and how active each project is.
