BMXtreme

BMXtreme is an extreme sports game released in 2000 for the PlayStation and Dreamcast, developed by Quarantine Development as their first excursion into original games and published by Crave Entertainment. A Nintendo 64 version was planned, but cancelled at the behest of the developers.

Gameplay
The game is set into two different modes, story mode and free ride. In free ride, you could play four different challenges, racing, pulling tricks, duel and ramp jumping.

In the story mode, six youths run afoul of an extra terrestrial being who wants to convert the town's biking population into human mice to power their ultimate weapon. You choose one from six characters and you travel through ten levels collecting parts, keys for the exit and other items. The game ends with the youths gaining alien powers and beating up the alien leader, reconverting their ship into a new bike park for everyone to play in.
