EA's Rock Band [App Store, $9.99] has appeared in the App Store, less than two weeks after word of the release was made public.
Rock Band offers a similar feel to the original console versions of the game, with some obvious differences due to the screen size and multi-touch interface of the iPhone. Players can to choose from guitar, bass, drum, or vocal tracks for each song, and player errors result in interruptions in music playback, providing integrated audio feedback on performance.
The game includes twenty songs in the basic package, with additional songs available for download via In App Purchase of two-track packs priced at $0.99. Also included is a local multiplayer mode via Bluetooth accommodating up to four players, Facebook integration, and a choice of single-song game modes or "World Tour" career mode.
