PC Couch CoopThis site has one purpose...to help PC Gamers, like yourself, find local coop (couch coop) & local multiplayer PC games. We're talking about games that allow two or more individuals to play simultaneously on the same PC (not over a LAN or over the internet, but in the same room, on the same couch, eating out of the same bag of cheezy poofs...the way video games were meant to be played).
