You know you want it. Just looking at that above graphic makes you desire the 4 player co-op zombie slayer Left 4 Dead from Valve Software. It's got zombies. It's got co-op. It's got car alarms.
The game is coming out on both the Xbox 360 and the PC, and right now you can preorder the PC version via Valve's Steam service for $44.99. So do yourself a favor, if you don't plan on snagging the Xbox 360 version of the game, go preorder this now from Steam, save a few bucks - and save yourself any wait time on November 18th from playing!
