Activision has finally opened the floodgates and revealed a torrent of information about Call of Duty: Black Ops 4. In addition to all-new Specialists and multiplayer options, this year's installment of the popular shooter franchise will also come with a Zombies story mode.

In Zombies, four characters travel through time to battle an evil cult, while killing hordes of the undead along the way. It's set across three unique missions, each of which has its own map: The Nine, Voyage of Despair, and Blood of the Dead.
