While pirates and ninjas may have had their time in the sun, these days mark the rule of the undead as they feast on all the brains they can find and absentmindedly shuffle around to find more yummy brains. The original Left 4 Dead took the zombie apocalypse and made it rather enjoyable by allowing up to four players to band together and survive the tireless horde. Also, if you ever tired of playing the good guys, the game's versus mode let you take the horrid abominations for a spin, killing those good-for-nothing "normals" in all sorts of grotesque ways. Less than a year later, Valve is going back to the zombie well with Left 4 Dead 2, and it's even better than the original masterpiece in every way."
