Here's the first glimpse of Zombies mode in Call of Duty: Black Ops 2. Apparently one level will be set on a moving bus—a first for the series.

The trailer reveals little else, but expect more next week—Activision has promised the Black Ops 2 Zombies "world premiere" next Frida, Sept. 26.

Will moving vehicles make a solid addition to the Call of Duty Zombies formula?
