User Rating: 9 | Left 4 Dead PC
Valve has always been known for making great FPS games, and while Left 4 Dead might not seem like much on the outside, it packs enough innovative features to make it a surprisingly excellent title. L4D plays out like a classic zombie apocalypse movie. You have four survivors from different backgrounds joining up to survive an endless horde of zombies and escape from the dangers. Left 4 Dead is divided up into 4 "movies" or chapters. Within each movie is four levels which makes for a total of 16 levels. In-between each level is a safehouse were you can stock up on weapons, ammo, and health packs. Left 4 Dead might only feature 6 basic weapons (pistol, Uzi, pump-shotgun, assault-rifle, auto-shotgun, hunting-rifle) they're enough to keep you going. And you'll need all the ammo you can get because you will be taking on A LOT of zombies. The standard zombies or "infected" aren't your stereotypical Dead Rising zombies. These guys will sprint at you in huge crowds and won't stop until your dead. Fortunately, they can't take much damage. But the real threats in Left 4 Dead are the boss infected. These zombies range from the Smoker who grabs enemies with his long tongue, the Hunter who moves extremely fast, the Boomer who is an obese zombie who vomits on people, the tank who is a zombie on steroids, and the witch who is a powerful female zombie who rips you to shreds. In the game's versus mode, 4 players assume the role of the survivors while 4 other player control the boss infected. This makes the game much more intense since people control the most powerful zombies. (Although you can't play as the witch because she's too powerful.) You can play the game by yourself with your buddies being controlled by bots, or you can play online with human controlled survivors. But what keeps Left 4 Dead from being to repetitive is the AI Director. The AI Director controls were the enemies are located (including boss zombies) as well as weapon and item placement which makes no two games alike. So once you complete the somewhat short game (4-6 hours), here's a trick, play it again. I guarantee the experience will be much different. So when you put all of this together, you get a surprisingly fun experience that any FPS gamer must see for themselves!
