Tom clancys endwar is pretty fun Also crysis 2 but it can be boring after a while, but my favorite is boderlands
crysis 2 homefront dirt3 blackops dukenukem la noir border lands + the dlc double pack disk you get darkside of the moon red faction armagedon theres loads m8 the possibilities are endless when you can play backups
Duke Nukem and Homefront were failures. Homefront is 75% sniping and Duke Nukem has horrible gameplay.
