With the official Call of Duty website updating yesterday after the announcement of Call of Duty: Black Ops 3, Charlie Intel discovered that the source code includes the game description.
Confirming a future setting and the return of Zombies, here’s what the source code says about Black Ops 3:
Call of Duty: Black Ops 3 is the first title for next-gen hardware in the critically acclaimed Black Ops series. Developed by Treyarch, the award-winning creator of the two most-played games in Call of Duty history. Call of Duty: Black Ops 3 deploys players into a dark, twisted future where a new breed of Black Ops soldiers emerges and the lines are blurred between our own humanity and the technology we created to stay ahead, in a world where cutting-edge military robotics define warfare. With three unique game modes: Campaign, Multiplayer, and Zombies, providing fans with the deepest and most ambitious Call of Duty ever.
