- This action/strategy game, released in 2009, starred actor/musician Jack Black as a roadie fighting evil in a heavy-metal inspired fantasy world
- Ozzy provided his voice and likeness to the Guardian of Metal character, who aids the main character Eddie Riggs in upgrading his equipment throughout the game
- Other metal legends that lend their voices to the game are Rob Halford, Lemmy Kilmister of Motörhead (who wrote several songs with Ozzy in the ‘90s) and Lita Ford (whose biggest pop hit, the Top 10 “Close My Eyes Forever,” was written and performed as a duet with Ozzy)
