A few days ago, we reported that promotional images of the new Revolution DLC for the Black Ops 2 had been leaked online. However, no official comments were given confirming the validity of the images or the existence of the DLC.
Yet despite the silence of the developers, the DLC was confirmed earlier today when a promotional image along with a teaser trailer made an appearance on the official mobile site of the game albeit briefly.
The Revolution DLC is rumored to be released on the 29th of January, and it will most probably be a timed Xbox 360 exclusive according to leaks on the internet.
Furthermore, a Call Of Duty forum member claims to have gotten hold of the information regarding the Zombie map, Die Rise, and the Achievements/Trophies in the DLC. You can read that post here.
