The player controls the Predator, who must proceed through a warehouse-like area to eventually find and defeat the Alien queen. Each level is laid out like a maze with a series of platforms and ladders. The Predator must find a key located somewhere in the level and use it to pass the exit door for the level (presented as a thick black block). A map is drawn at the top of the screen and is filled in as the player explores the level to aid in navigation. The Predator has an energy meter that starts at 50 and gradually decreases over time. Once the meter has emptied, the Predator's map will slowly be completely cleared. Some levels feature an energy power-up that will refill the energy meter.
