Why we do it
Some of the best games ever made were built for one player. We think they deserve a second.
How it works
Single player in, co-op out
Every project here takes a game designed for one and makes room for more.
- 01
Pick a solo classic
We start with great single player games that never shipped with multiplayer, or only ever dreamed about it.
- 02
Add co-op
We add co-op to the game, so the story you know can be played with friends.
- 03
Grab a friend
Install the mod, invite a mate through Steam, and replay the game you love together. Everything lives on GitHub.
