LEFT 4 DEAD RULES
the one the i didn't like (the only thing) is that all the levels of difficulty are relatively easy, other thatn expert ofcourse. You build up to expert easily, and then finally start playing on it. I found that expert is a huge jump from the other difficulties. I'm hoping that changes in the sequel.
other than that left 4 dead is an extremely creepy and pleasing game. I'm looking forward to the new game. HURRAY FOR CHAINSAWS!
