Collider writes: "I have always been a fan of games made by Valve. Whether it be the original Counter-Strike or Half Life, or last years remarkable Orange Box, they are one of the best game developers around. That being said, Left 4 Dead is an absolutely incredible game and needs to be in any gamer's collection. Though it does have a few short comings, they are easy to ignore when the game play is this fun and intense. Valve has definitely done it again, and all will enjoy this game in any of its various modes. Though the co-op is really the star of the show here, nobody will be disappointed by the single player or versus experience."
