"In the indeterminable depths of space, Asteriod Sury-Ani 7 floats majestically in a 400 year orbit. The crater scarred surface obscures the danger that lies below - a danger conjured by man in his attempt to strive forward in space colonisation. Radio-active canisters that were due for disposal now lie exposed in Sury-Ani 7's mining complex. The human inhabitants have now departed and only you - a disposal droid remain to dispose of the canisters before they become critical and annihilate the whole complex" - from rear of cover
