War in the future is going to be fought by small Metal Mickey-type characters in brick mazes. You are a Combat Warrior Droid. Equipped for battle, but with various types of battle to fight, you must customise your kit according to the combat arena you are in. The more armour and weaponry you take on board, the heavier you become and the slower you run.
However, in order to upgrade, you have to trade with local merchants, some more honest than others. Other aspects include insuring the droid, the repair shop and the bookies.
It is a sort of poor man's Alien Breed but good fun nonetheless.
