From the Quake 2 Manual: Another multiplayer mode is Cooperative or "co-op." In a co-op game, up to four players can join in a game to combat the monsters of Stroggos as a team. The rules for this method of play are similar to a single player game, except up to four people can go after the enemy together. If you are killed in co-op, you reappear at the start area, and have to catch up to your buddies.
A first-person shooter set in the Earth-Strogg war. You are a lone marine sent to the Strogg homeworld to destory a big cannon before the actual invasion force can land.
