Velius and I were talking about the new Gears of War for PC that is coming out soon and we got to lamenting how there are no more really good co-op games out anymore (GRAW was so painful!). I have been trying to keep up with E3 news this week and I saw this game Left 4 Dead under development.
It seems like the ultimate co-op zombie game! You play 4 survivors fighting off massive amount of zombies or for a change you can play zombies. I was watching a dev interview and it says the zombies have a AI director and are being procedurally generated based on survivor experience so you can never predict them. I think it will be really fun to play when it comes out. The graphics doesn't look too crazy either so our computer can probably handle it lol.
