The game is centered around a research scientist called Travis who works at a high energy institute experimenting with dense matter and the theoretical creation of black holes for interstellar travel.

One experiment goes wrong and Travis is trapped in an anti-matter bubble world. Travis can wander around a level freely to search for the radioactive deposits that will send him home. There are 5 sections to the world where deposits of the material can be found. Travis must traverse each level, looking for all the deposits that exist there before he can afford to waste the energy for the short jump to the next section. When all of the radioactive deposits on a level have been collected, the level fades away as Travis tele-ports into the unknown.
