Here's a new video showing gameplay from the Apocalypse DLC for Call of Duty: Black Ops 2, which launches tomorrow for the Xbox 360 edition of the military shooter sequel, and will come soon to Windows and PlayStation 3. Here's the pitch: "Call of Duty®: Black Ops II Apocalypse marks Treyarch's fourth and final DLC map pack for Call of Duty: Black Ops II, capping-off the year with two all-new Multiplayer Maps, two re-imagined fan-favorite Multiplayer classics, and an alternate-reality Dieselpunk Zombies experience that transports players to the undead-infested trenches of a World War I battlefield."
