Left for dead on the nightmare planet, your only hope of escape is to find the Doctor deep down on Level 7 and pay him 10 bags of gold to transport you to safety in his time machine.

The monsters get stronger the further you descend into the heart of the Base. A good strategy, therefore, is to build up strength on the upper, easier levels by killing monsters and collecting gold before progressing downwards.

After the instructions have been displayed and the final part of the program has loaded, there will be about a 10 second wait while the game is set up.

Z - Left, X - Right, * - Up, / - Down, T - Take a Hulk Pill, P - Pick up Gold

To pick up the Gold, move into the corner of the room and press P for each bag of Gold. You will not be able to do this if there is a monster in the room.

Taking a Hulk Pill doubles your strength for five seconds and allows you to walk through walls, but when you revert back your strength diminishes to one third of its original value.

For details of the many types of monsters you will encounter, see the instructions included in the program. Good luck!!
