Call of Duty: Black Ops 2 is getting an expanded co-op mode called "Tranzit" that'll send four survivors on a zombie road trip across the US. As one of those survivors you'll get to bus from place to place, mounting heroic stands against the zombie army at each location. IGNmention "buildables" that con be constructed to furnish you with new weapons, or open up extra areas, which are probably full of more zombies.

The latest Black Ops 2 zombies trailer shows a fuel stop, a diner, a farmhouse reminiscent of Left 4 Dead's Blood Harvest finale, a power station and a town center blighted by lava pools. Zombies AND lava? It's the doompocalypse alright. You'll find the video stamped into the page below.

Parts of the video show a tiny snippet of someone shooting zombies of the roof of the bus in first person, suggesting that we'll have to defend against legions of zombie marathon runners as the bust travels between locations.

As well as "Tranzit" there will be a versus mode that will put two four-player teams into the zombie apocalypse and encourage them to compete for zombie kills without killing each other. There will be a more traditional survival zombie mode for fans of Treyarch's previous efforts.

Treyarch could probably spin zombies into a separate release if they wanted to. It's been a fan favourite since its cheeky first appearance in World at War. Is the zombie mode your favourite part of Treyarch's CoD games, or just a fun distraction?
