"Surprise," the new live-action ad for "Call of Duty: Black Ops 2," turned out to be appropriately titled. The commercial features a series of gamers thinking they've just earned the upper-hand in an online firefight, only to be sneaked up on by another player.

One of the those gamers ends up being Iron Man himself, Robert Downey Jr.

"Guess who brought a jet to a gun fight," he quips in the most Downey-esque way.

The cameo actually makes sense considering that it was directed by Downey chum and "Sherlock Holmes" director, Guy Ritchie.

"Call of Duty: Black Ops 2" hits Playstation 3, Xbox 360, and PC on November 13.
