This is an awsome game there are 8 campain missions + all the campian maps but you can choose how you do them and stuuf(custom mission).There are about 20-30 primary weapons(assalt rifles, snipers,machine guns rpgs etc.) and about the same secondary(pistols and subs) its a very fun/realilistic game.Theres also online play where you can play with other people...I highly suggest this game =)
