What we all have been waiting for, the full confirmation about the news of Call of Duty: Black Ops II integrating Zombies on its features.
After a lot of advertising by the publisher by posting screenshots and art designs, we have been given an teaser trailer for this, showing the co-op mode, which is called "Tranzit" on something which might remind us a little bit about L4D times, as on this campaign, four survivors are on a zombie road trip across the US. Each player will take place of one of said survivors and get into a bus to go from place to place.
Something to be aware of is that there are hordes of hungry zombies out there, which will be waiting for said survivors to appear, and players will need to definitely cooperate between them to be able to survive the waves of zombies on each location of this campaign.
Another interesting feature of the game is the versus mode, in which two teams of four players each are placed into this zombie apocalypse and will be competing to get the most zombie kills, without killing each other.
