The Soundgarden compilation album bundled with initial shipments of Guitar Hero: Warriors of Rock was Telephantasm.
Released in 2010, Telephantasm collected songs from Soundgarden’s career and included “Black Rain,” a previously unreleased track. That song was also added to Warriors of Rock as a playable song, linking the promotional album directly to the game’s soundtrack. The bundle gave game buyers a substantial piece of Soundgarden’s catalog rather than a newly recorded game-exclusive album.
The promotion had an unusual commercial result: because more than one million copies were shipped with Warriors of Rock, the Recording Industry Association of America certified Telephantasm platinum based on those distributed units. It became a notable example of a video-game promotion helping an album achieve a major sales certification. The other options are Soundgarden releases or related titles, but none was the album included with the game’s initial shipments.
