Left 4 Dead, Valve Software, zombies, co-operative multiplayer, PC (and Xbox 360).
I can't really think of any additional words that you'd need to hear to awaken a spark of interest in this game. Let's just say that it was one of the few games that really grabbed my attention at E3 (hardly surprising as it was one of the few PC-based FPS games). It is shaping up to look very cool and after the brief chunk I got to play I can't wait to take the final game for a spin with some mates.
