Avenged Sevenfold have released a new song for the video game Call of Duty: Black Ops. The track, appropriately titled "Not Ready To Die", is available on the latest CoD downloadable map pack "Escalation".

A7X frontman M. Shadows spoke with Revolver about the song.

"We had a little break between the Nightmare After Christmas tour and the Welcome to the Family tour," the singer said. "So it was written, like, in four days that we had off. So it was pretty rushed. It was pretty incredible, though, because we really wanted to do it. It was written, like, a month or two ago."

M. Shadows admitted to being a big video game fan and jumped on the chance to write a song for the popular Call of Duty series. "Not Ready To Die" is about Black Ops and its zombie story in particular.

"There’s a full backstory to what [the makers of Call of Duty] been doing for years with their 'Zombies' series," explained Shadows. "I’m a big fan of the game, I play it all the time, so I got caught up in the story. They sent me over the full storyline, so I made sure it was going along the lines of the zombie story. So that’s what it’s about."
