Aw that sucks. My disk is all messed up now, but I downloaded the game onto the console before the disk got too messed up. I can still play it, but some of the textures are all wonky which is kind of annoying XP
But yus! If you got the money, get another disk. Cuz L4D is awesome XD
It's the best game that ever existed! I am the master of Dead Rising! Here's two quick examples of how outrageous it is, in DR2 Off the Record there's a weapon where you duct tape a sickle and a katana sword together for you to use. and an achievement where you have to kill 100,000 zombies to get it. http://www.youtube.com/watch?v=ZEn3QIzQcFA
