Left 4 Dead 2
I could write about the games new features and how excited I am about it but I think I'll just let the videos do the talking.
"It is true, that which I have revealed to you; there is no God, no universe, no human race, no earthly life, no heaven, no hell. It is all a dream - a grotesque and foolish dream. Nothing exists but you. And you are but a thought - a vagrant thought, a useless thought, a homeless thought, wandering forlorn among the empty eternities."
