This is a track pack for the Rock Band games and in the United States it was only available at the Wal-Mart and Sam's Club chains of stores. The original game is not required to play and Volume 2 includes all eighteen songs of the album Live at Donington by rock band AC/DC. Contrary to the other track packs, it does not include many of the regular game features such as avatar customization or online play. The game also includes a code to export the songs to a hard drive for use in other Rock Band games (PS3/Xbox 360).
