One of 2012's must-play games is, of course, Call of Duty: Black Ops II. Along with introducing new weapons, terrains and even zombies, the second chapter of the Black Ops franchise also includes an in-game performance by Avenged Sevenfold.

The brand new track 'Carry On' is not only a part of the game's soundtrack, but a part of the game itself. Singer M. Shadows and guitarist Synyster Gates deliver a few lines as bad-ass versions of themselves right before the entire band is joined by a couple of characters for a performance of 'Carry On' during the closing credits.
