"Left 4 Dead is a great addition to the zombie game genre. It's a complete other direction from Dead Rising, which is a good thing since Left 4 Dead is one of the best co-op shooters around. Great graphics, great sound, great cinematic, great gameplay, almost everything about L4D is great. The only downside is that, no matter how good the gameplay is, the single player mode feels a little empty after playing through a few co-op levels. But this is where the game shines, even with one friend and two AI assisting this game is great."
