If the amount of assets being released is any indication, Activision is pretty excited about Guitar Hero Metallica, especially now that it's available for purchase.  Or maybe they just want you to buy, buy, buy.

Either way, the newest video is a U.S. launch trailer, featuring in-game footage and brief commentaries from the band members, accompanied by little quips here and there.  Supplemented by tunes most of us recognize off the bat, this latest Guitar Hero Metallica trailer will get any metal fan going. 

And as we mentioned before, you're getting more than Metallica with this game.  King Diamond and Lemmy make guest appearances, and players will be getting a healthy dose of Queen, Judas Priest, Alice in Chains, Foo Fighters, System of a Down, Slayer, and many more -- with an emphasis on many.
