In the eerie underground of Subterrania you are being pursued by berserk aliens. You can race through the maze to avoid them and you can shoot at them to fend them off. Plug the joystick into port 2. Press the fire button to start on level one.
Move around the caves using the joystick. Wherever you go the aliens seem to follow. You have three lives, which you lose one of each time an alien comes in contact with you.
You can destroy an alien by shooting at it using the fire button. Each one you hit is worth 50 points. And you earn bonus points each time you reach a new room.
