1UP has a short, but sweet preview of Valve's Left 4 Dead.
When your batting average is 1.00, nobody doubts your skills. And our playtests have only confirmed this. The zombie setting is scary as hell (hooray for fast zombies!), and the co-op gameplay, with small, great touches like the ability to pull zombies off your friends, is both easy to get into and ripe for longer-term mastery. Like Portal, Left 4 Dead originally had a much lower profile in Valve's arsenal of games (when the Half-Life franchise is in your portfolio, it's hard to compete), but now that it's nearing release, Left 4 Dead is taking center stage, and is more than holding its own there. Look for it to dominate the multiplayer shooter scene when released this fall.As mentioned, Left 4 Dead will be made available on November 4, 2008 for the PC and Xbox 360.
