Activision has released a trailer for Call of Duty: Black Ops 2 DLC pack Revolution, out over Xbox Live on 29th January for 1200 MP. The pack adds four new multiplayer maps, a bonus multiplayer weapon in the form of the Peacekeeper SMG, and the opportunity to play as the undead in new Zombies mode, Turned.
You'll get the barest whiff of all that in the trailer, though, which mostly consists of live-action humour. Verdicts on the latter will probably vary. Go on, meet the Replacer. Let us know if you make friends.
