Blabbermouth has posted footage of an early teaser trailer for the forthcoming Metallica version of Guitar Hero due out in 2009.

The video prompts players to “unleash your inner metal god” while Metallica’s seminal 1986 thrash classic “Master of Puppets” plays in the background. Very metal, though it shows no in-game footage.

Widely considered the “Heavy Metal CNN,” Blabbermouth reports the footage is included on the Guitar Hero: World Tour game disc.

Metallica’s latest album Death Magnetic will be available as DLC for Guitar Hero: World Tour, which also includes the individual song “Trapped Under Ice” from their 1984 album Ride the Lightning.
