 At an earlier stage in its development, "Savage Skies" had been set for release as "Ozzy’s Black Skies", complete with an endorsement from Black Sabbath front man Ozzy Osbourne.In the original concept, each of the game's three playable factions would have been led by a different ‘Ozzy character’.The game was also to feature music from Osbourne, including "Crazy Train" and "Paranoid," as well as a track recorded specifically for iRock (the song was called "Black Skies").
