The player's character is Roddy, a sixteen-year-old boy at the helm of an all-terrain combat vehicle, S.O.P.H.I.A. The player pilots SOPHIA through a labyrinth of 3D rooms in search of clues to the enemy's movements. Occasionally the player will encounter enemy installations or limiting topography that will force Roddy to leave Sophia, and advance on foot. As the game progresses, new equipment will be made available for SOPHIA, allowing access to new areas.
