I got this as part of the
Indie Royale Debut Bundle #2. And basically...yeah, it's pretty fun. It's got all the Punchout! stuff here with ridiculous characters [with their own special moves and particular strategies] and the standard array of punches [jabs, uppercuts, hooks, ect.], but it's all together in a pretty nice package and it does introduce a stat/equipment system to distinguish itself. The controls are nice and smooth and it's compatible with the Xbox360 controller. Plus, I mean, your coach is a pig wearing a hat and a Hawaiian T-shirt.
Beast Boxing Turbo, along with the others games in the bundle, are all on Steam Greenlight:
