Robotron: 2084

You are a human mutant who, due to some strange quirk of nature, possesses the power to release energy pulses from your body in eight distinct directions. Your mission is straightforward: protect humanity against the ROBOTRONS they have created themselves. The gameplay is pretty innovative for its period. You can move and fire in any of the eight directions available. You are placed in a room with various dangerous foes lying about you, and your objective is to eliminate all of the robots while simultaneously locating a way to rescue humanity and keep yourself from being killed.
