id Software has dropped the price of the iOS version of its Rage game to free for a limited time. Rage for iOS is an arcade style rails-shooter that has been adapted from the upcoming PC and console version due later this year. The iOS version came out back in November:
RAGE for iOS begins with a selection of three levels (or, "seasons" of the Mutant Bash TV show) along with difficulty levels ranging from "easy" to "nightmare". The goal is to make your way through each of these levels and earning as much in-game cash as possible. RAGE for the iPhone is entirely on rails, and it plays a lot like other arcade-style rails shooters like Time Crisis. The game runs you through each level and you control your field of view, aiming at things with a crosshair in the center of the screen.
The price drop was in response to a Facebook related promotion and will be free for the next week. Both the standard version [App Store] and iPad versions [App Store] are free.
