The game starts by choosing one of the 3 classes with their own special weapon preferences. After joining you find yourself next to your crashed ship on Borridor and quickly notice you are not alone.
While you hold off waves of hostile Borridorians and other creatures you must try to collect craft materials. Use your compagnion robot 'Craftbot' to create weapons and items to assure you are ready to take on the spacecops.
When the space police notices something is going on on Borridor they will send in squads to stop the chaos. The spacecops carry 'Ship fuel'. This is the key element needed for your ship to take off and escape.
