Konami Digital Entertainment announced today that it is developing Walk It Out, a rhythm-based physical fitness title for the Nintendo Wii. In Walk It Out, players stroll through a virtual world that evolves in sync with an on-screen avatar's footsteps. Skyscrapers, windmills, and lighthouses will spring up as players successfully step to the beat of a background music track. Walk It Out uses the Wii Remote and Nunchuk to track player movement. The game also supports the Wii Balance Board peripheral, and is compatible with Konami's own Dance Dance Revolution dance mat controller. 120 songs are featured in Walk It Out, including "Boom Boom Pow" by the Black Eyed Peas, "La La Land" by Demi Lovato, and Jesse McCartney's "How Do You Sleep?" Walk It Out is the latest Konami release to feature gameplay that focuses on physical fitness and exercise. Previous fitness-oriented Konami games include Let's Pilates and Let's Yoga for the Nintendo DS, the Japanese PlayStation 2 title Aerobics Revolution, and the multiplatform Dance Dance Revolution series.
