Not sure if I posted this one yet, just came out recently. I loved Zombies on BO's 1.0 and looks like 2.0 Zombies are going to be great. From what I've heard, there is going to be an actual campaign in Zombies. Plus you can also square off against other teams in Zombies mode. Meaning 4v4+Zombies= SHTF quick!!
