The players must battle to remain alive for as long as possible without hitting the trail of the "Acian energy" left by the opponent or one of the four walls.

The Players guide their craft in four directions by rotating to the left or right using one of two keys. Both Players scores are incremented while you are alive, but once crashed your score remains unchanged. The game continues until both of you have crashed. The Highest score is kept in the Hi-score table.
