Zombie modes detailed for Call of Duty: Black Ops II

Activision have at last lifted the lid on the oft-teased return of zombies within Call of Duty: Black Ops II.

Alongside a gameplay trailer it has been announced that there will be two new modes, Tranzit and Grief, according to Polygon.

Tranzit sees players travel between different zones in a fortified bus, and is a co-operative story mode, whereas Grief is a competitive mode in which two teams of up to four humans must lure zombies at each other to kill their opponents.

Call of Duty: Black Ops II is confirmed as a Wii U launch title.
