Alien Swarm is a free game and Source SDK release from a group of talented designers at Valve who were hired from the Mod community. Available free of charge, the game thrusts players into an epic bug hunt featuring a unique blend of co-op play and squad-level tactics. With your friends, form a squad of four distinct IAF Marine classes.
Although the game works in 3x1 surround, I couldn't play like this as it is too important to keep an eye on your ammo/health/teammate health and to time your reloads. Having the player info on the left screen was a no go; no time to look over there in this game, plus most of the game involves vertical movement and I have 3x1 landscape, so not helpful.
