Game is alright unless you want to do anything besides multiplayer. Campaign: I honestly finished the final mission and went "Oh, that was it?" Co-op: The missions aren't hard until you get to the part where the enemies spawn faster then you can kill them and then the game decides to throw multiple bullet drinking juggernauts at you. I've tried all of the missions with a group of 3 experienced fps friends and we only finished 2 of them. Don't even touch the "Classic Co-op" because it's the same as normal but you can play it without 4 people. Good luck.
Multiplayer: The normal COD experience where you will get magically head shot by the person you shot in the "shoulder" and when you stop watching a corner the entire enemy team decides it's time to peak.
As much as this game infuriates me I keep coming back to it, but I will uninstall it if they don't fix the dumpster fire that is the barrack missions.
