Oh no a mainstream game, better hate it immediately.
Anyway, it's pretty fun. Campaign was actually kind of engaging, though it does stick to the "Oh stuff if you don't succeed the US will be forgeted" formula most of the games have been using. The multiplayer isn't that different in comparison to the others, but there's definitely some new gameplay elements that set it apart from the rest. Zombies is cool I guess; I'm not any good at it.
