“This Teenage Mutant Ninja Turtles game is
based on the CG animated movie produced by Imagi Animation Studios and based on Mirage Studios’ Foot Clan-kicking Turtle heroes. The game takes place in a New York City plagued by secretive villains and
strange, otherworldly creatures. Faced with these perils, the Turtles will experience their most trying time as heroes and as a family, as Raphael, Donatello and Michelangelo lose their focus and struggle to
maintain their unity and ninja discipline.”
Let me tell you now though, those people expecting classic TMNT rock will be disappointed. Virt writes:
“If you’re looking for nostalgic rocking out, you’ll be incredibly disappointed – this is a much darker game than the old ones, so I wasn’t allowed to unleash the Konami rock fury, it’s mostly orchestral/electronic underscore and beats, with guitar in only a few tracks (as a motif for a specific character) Decision from up high, nothing we could do.”
He goes on to say more in this VGMix thread, which also has links to videos on IGN, showcasing the game and its music.
