Thruster Ball

Published in Zzap!64 Megatape #19. The object of the game is to shut down 40 or more reactors dotted at various points throughout the map. To aid you in this task extra weapons and pick-ups can be acquired. On shooting a wave of aliens either a crystal or pick-up will be released. On picking up a crystal you are given a credit towards the purchase of an extra weapon. If, on the other hand, you acquire a pick-up you may be given a bonus or something to hinder your progress. In one person play you have a drone that follows you, it's armaments may be upgraded. In two player, the drone is controlled by player 2 and can go places the Thruster Ball cannot.
