Art dealer Sal Abbinanti has revealed Alex Ross' cover for Origins, the Zombies map included as part of the upcoming Apocalypse downloadable content package for Activision's Call of Duty: Black Ops II.

From the sound of it, Origins is pretty much what you'd imagine, with players fighting to survive wave after wave of the undead. Only in this case, it's set during World War I, with giant mecha and the like -- which you can see looming in Ross' art, below.
