After months of dilly-dallying with meaningless teaser trailers, Activision's finally dug up the details on Call of Duty: Black Ops 2’s zombies component. As expected, the mode will be significantly more ambitious than previous endeavours – boasting new game types for up to eight-players.

In addition to the usual Survival option – in which groups of players work together to fend off waves of the undead – the game will also feature Tranzit and Grief modes.

The former will be a story-heavy mode set in an “expansive world” where players can ride a fortified bus to reach different districts of the map. Apparently, your actions in last year’s Moon DLC (released for the original Call of Duty: Black Ops) will have an effect on what happens in the sequel. "If you played Moon, the actions you had there may have had some impact on what happens in Black Ops 2 Zombies,” Treyarch’s Mark Lamia teased.

Meanwhile, Grief pits two teams of four against each other with participants unable to attack each other directly. Instead, you’ll need to lure zombies towards your opponents, and let them do the nasty business for you.

There's a reveal trailer embedded below. Let us know what you think in the comments section.
