The new Zombies mode for Call of Duty: Black Ops 2 will actually feature three different modes to kill the undead in.
The first mode, Tranzit, will have players exploring a “big, giant, expansive world” either on foot or on a bus. While trying to survive zombies in this huge world, players can find items to make new weapons, tools and items.
The next mode, Survival, has players killing zombies in just a single area from the Tranzit world. This will play similar to the previous zombie modes.
The final mode, Grief, lets up to eight players team up in two teams of four to try and survive the zombies the longest. While players can’t kill each other, they can block passages or find other ways to grief the other team, hence the name.
