It's the year 2575. You are one out of over 1,500 humans to be enrolled as a student of Earth for Luna University, a College that had recently been set up and sponsored by the E.T.A.S.S. (The Extra Terrestrial Alliance of Sapient Systems). It's been set up on the Moon within a Bio Dome settlement as big as a large city.

For whatever reason, you've found yourself outside long after the university's evening curfew. Whether you couldn't sleep, were returning from a late-night study session, or simply wanted to explore campus after dark is entirely up to you. Whatever the case, the distant sound of cheering draws your attention toward Luna University's outdoor skatepark, where one engineering student's latest experiment is about to make campus history—or become another spectacular disaster.
