You move about a randomly generated maze, searching for three phantoms to kill. When you begin the game, you can select whether you want a simple maze, with lots of long hallways, or a complex maze, with lots or turns and dead ends. When you find a phantom, you shoot it. Once you kill a phantom, it regenerates in a random location in the maze. Each time you kill a phantom, they will then require more shots to kill. Also, in the maze, is a randomly placed teleport square that will charge you and place you in the center of the maze as well as briefly show you a map of the maze, including the phantoms. The teleport square regenerates after it is used.
