This is the day gamers have been waiting for! ‘Call of Duty: Black Ops II,’ which hits shelves today. It was previously announced that Avenged Sevenfold‘s song ‘Carry On‘ would be part of the game’s soundtrack, but now we have learned the band makes an appearance in the game, as well.

The ‘Call of Duty’ games are massively popular. The first ‘Call of Duty: Black Ops’ game was the largest ever entertainment launch, bringing in a staggering $650 million within five days of its release. That record was broken by ‘Call of Duty: Modern Warfare III.’ Could ‘Black Ops II’ be the biggest seller yet? We’ll find out.

If you stick around until the end of the credits, a virtual A7X performs ‘Carry On.’ In addition to the band, characters from the game join in as well. A nervous Raul Menendez plays guitar, and Sergeant Frank Woods is behind the drum kit.
