Jimmy Fallon has once again put his hands on an upcoming game - this time it's Call of Duty: Modern Warfare 3 that Fallon, together with Simon Pegg, got to play. The New York-level we saw at E3 was shown, together with a "wave" from the game's Spec Ops-mode.
Considering that it seems to be a pretty slow news day, you might as well have a look over on YouTube for the whole thing.
