Konami has released its DanceDanceRevolution S game for the iPhone and iPod touch. Based on the popular arcade dancing game series, the main Game Mode requires users to tap on the screen to the rhythm of the song, with upcoming arrows rising from the bottom of the screen. Two other game modes are available, including Shake Mode, in which players shake the device in the direction of the arrows, and Training Mode, which helps novice players acclimate themselves to the main game mechanics. In addition, the game offers 26 and 18 playable characters, with a soundtrack featuring both new and old tracks from past DDR titles. DanceDanceRevolution S is available now and sells for $7; a free Lite version is also available.
