ESRB entries and leaked achievement lists be damned! MTV Games and Harmonix have officially announced the Rock Band Metal Track Pack, a stand-alone disk with 20 tunes guaranteed to shake the very foundations of heaven.
On top of the five songs already revealed through the various leakages, the Rock Band Metal Track Pack features fifteen songs previously released for the game and one additional exclusive track, Rage Against the Machine's "Bulls on Parade". Each of the six exclusive tracks will be available in the Rock Band Store after everyone who wanted to buy the retail disc has done so.
The rest of the songs in the collection have already been released in the store, but store-less PlayStation 2 owners are sure to appreciate the effort.
The Rock Band Metal Track Pack hits retail store shelves on October 13 for the Wii, PlayStation 2, PlayStation 3, and Xbox 360.
