Rock Band is about to get a little more metal, with the impending release of another metal-heavy track pack featuring Motörhead, Blue Oyster Cult and...Hawkwind.

News of the pack comes via two sources; an ESRB rating and a leaked achievements list, which when combined give us the following songs:

The Haunted: DOA
Blue Oyster Cult: Transmaniacon MC
Nazareth: Hair of the Dog
Hawkwind: Master of the Universe
Motörhead: Killed by Death

Those might be the only songs the pack includes, it might just be a selection from a much larger pack, we don't know. All we do know is, this game needs more [insert favourite metal band from the 80's/90's]
