Modern Warfare 3's Survival mode shown off on US TV

Developers play the new Spec Ops game with funnyman Simon Pegg

Activision showed off Modern Warfare 3's new wave based co-op 'Survival' mode last night on American TV.

Publishing CEO Eric Hirshberg, Infinity Ward's Robert Bowling and Sledghammer's Glen Schofield appeared on Late Night with Jimmy Fallon to publically reveal the mode, and fellow guest Simon Pegg got in on the action too.

The mode, which comes as part of the new game's updated Spec Ops suite, has players competing against increasingly difficult waves of enemies across Modern Warfare 3's multiplayer maps. Get more details here, or just watch the video below.
