Los Angeles-rockers Thirty Seconds to Mars are the headline act on the Dragon Age: Origins soundtrack, BioWare and Electronic Arts announced today.

The group’s new album, “THIS IS WAR” doesn’t release until December 8, but we know you. You care not for calendars and their silly numbers because you can hear it today, in the game!

“EA has always had a forward-thinking relationship with Thirty Seconds to Mars and we are overwhelmed with excitement about the band’s involvement and creative contribution to Dragon Age: Origins,” said Steve Schnur, Worldwide Executive of Music and Music Marketing at EA. “This exciting song debut exemplifies our continued commitment to working with great bands that move the needle to where music is going.”

“We always like to push the envelope in the entertainment and media space and debuting our title track in a game of this caliber is a great way to communicate our music to fans around the world,” said Jared Leto, lead singer of Thirty Seconds to Mars. “We’ve come a long way from having to rely solely on radio to approach and engage music fans, and Dragon Age: Origins is the perfect game to do this with.”

If you picked up a copy of Dragon Age Origins for PC, PS3, or Xbox 360 already played the game, you probably already heard the tune, but for those who haven’t, BioWare and 30 Seconds compiled this trailer, showing you all you’re missing.
