Zombies are fast. Zombies are hungry. Just remember that it you don't have to be the fastest person out there -- you just need to be faster than the guy next to you. This direct-feed footage from Left 4 Dead show four survivors (sorry, no footage of someone playing as a super zombie) making their way through a bloodied, abandoned subway system. It looks intense; it should make for an interesting team game when it hits Xbox 360 and PC in early 2008.
