Releasing these new screenshots, Microsoft has announced that Boom Boom Rocket, a music game developed by Bizarre Creations, the company behind Project Gotham Racing 3 and Geometry Wars: Retro Evolved, will be available for download for Xbox 360 beginning Wednesday, Apr. 11, at 0900 GMT (2:00 a.m. PDT). In Boom Boom Rocket, players trigger rockets to the beat of the music while traveling through a 3D cityscape. The better the player times the explosions, the more spectacular the fireworks effect. The fireworks are choreographed to 10 original tracks created by Ian Livingstone, who recently scored Batman Returns and Project Gotham Racing 2.
