Beat Hazard Ultra, the procedurally generated twin-stick shooter by 1-man indie powerhouse Cold Beam Games, is now available as a Universal App for iOS devices. As with the PSN, XBLA and Steam versions, Beat Hazard Ultra uses music stored on your device to generate its levels. The game can also use streaming radio apps as its musical muse, a feature which is unique to this version.
Beat Hazard Ultra supports Game Center leader boards and achievements, although the PSN version's online multiplayer fails to make the jump to iOS. Between Survival, Boss Rush and Chill Out modes, though, it certainly sounds like you'll get your dollar's worth out of the title, which happens to be the app's limited introductory price.
