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.
