First, and most importantly, the campaign. You play as Troy Baker clone number 9000, a man who Kevin Spacey doesn't like. Kevin Spacey had a son, who got killed because of you, but nobody knows that it was because of you. Those helicopter doors don't troll anyone by themselves. Then you get a new arm as a reward. An arm that would disappoint Adam Jensen. There's also a woman, with a slow, Russian accent, who owned everyone in grenade training. Well, a lot to talk about. You're going to have to play it yourself.
The multiplayer is back! But now, everyone has a jetpack that only seems to work in bursts. And then there's shooting.
The great Spec Ops Survival co-op returns from Modern Warfare 3! But now, enemies don't care about taking cover and think they're in a match of Unreal Tournament. They also come in numbers and have guns.
