The game is good but not great. In the first one the maps (dead air,deth toll,ect.) did not tie together in the start and end it was just survive, it never showed how you got there or anything. In l4d2 they tie together. After you get out of the mall in dead center you take the car and the naxt map the car is on the highway and can't go any more. After that map when you get in the chopper it crashs in the swamp (where the next map starts) It is more of an online game so if you don't have xbox live than it gets boring after a while. But its a good gam so i say give it a try.
