Let's be honest: the campaign wasn't great. But MW3 has brought was COD is known for: addicting online gameplay.

The campaign wasn't great, but could be made a challenge on a higher difficulty. The online gameplay is the important part here. As always, new guns and maps have been introduced. Unlike Black Ops, MW3 isn't a huge step up from MW2, although it packs enough to keep hardcore gamers pleased and others satisfied. The maps are great and the guns are even better. The only thing I really hated from this view was Downturn (I just HATE the layout of the map). Also, a new mode called infected has been introduced. This mode is absolutely amazing. Basically, one player gets infected at the beginning. Infected have only a knife and a throwing knife to kill and a tac insert to keep in the action, although they are given guns to get the first kill. Others are armed with simple guns, no equipment and stuff. The goal is either to survive by killing off the spawning infected or infect the survivors. Everything else in the game is pretty similar to previous COD games aside from the new killstreaks (if you don't have the game, MOAB is the new Nuke, and can be obtained by getting 24 kills with only your gun).
