Priced at $0.99 for the regular version or $1.99 for the iPad and iPhone 4 'HD' edition, Mutant Bash TV is based upon Rage's gladitorial game show of the same name.
"This is the perfect setup for a quintessential first person shooter game play experience," Carmack has explained. "You pick your targets, aim your shots, time your reloads, dodge the bad guys, and try and make it through to the end of the level with a better score than last time."
Rage itself is slated for a PC, Xbox 360 and PlayStation 3 release on September 9, 2011. Another, unrevealed mobile Rage game is also due to arrive around then.
