I would talk about how amazing everything is in Left 4 Dead, but at this point the awesomeness should be obvious. I was actually not sold at all on this game and was about to write it off as another generic shooter... then I played the demo. Needless to say, trying to beat that demo on expert with any 3 friends I could track down online has proven to be more important than sleep lately. Check out the demo and ramp up the difficulty, its not fun until your shrieking with fear as hordes of zombies meet you at every turn or when a smoker pulls you away when you thought everything was finally OK. I am very excited for the final product, no idea how I will manage to beat the full campaign on expert, but I will damn well try.
