Duty Calls is a parody game of Call of Duty. there er... isnt much to describe about this game(im serious, there really isnt anything to describe it) Just think Call Of Duty made funny.
Duty Calls parody game viciously sums up the Call of Duty experience in one painfully funny four-minute experience complete with boring briefings, bloody screens, and the obligatory slow-motion shoot-out.
