The Date: 2593 A.D.
The Planet: Alpha Centauri 3, 8.6 Light-years from Earth.
Background: Originally settled by human colonists for the purpose of mining the rich ore deposits and shipping them back to the resource-depleted Earth.
Recent Events: A predator drone ship placed alien eggs onto the planet, which hatched and produced a fine crop of alien prey. The human population was eradicated in the process. A predator hunting party then arrived to hunt the aliens, but the number of aliens was underestimated and all the predators were, in turn, wiped out.
Theory: An alien queen is present, which would explain the larger-than-anticipated population of aliens.
Mission: It is now up to you, the last of your clan, to regain the predators' honor. And your own.

You control 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.
