The Sacred Armour of Antiriad

A passive and peaceful society established on Earth by the year 2086 has its idyllic existence shattered by an invasion of an alien attack force. The populace are sent to work in the aliens' mines. Some rebelled, but one stood out as the most hardy and courageous. Named Tal, he was instructed by the elders to explore the land in search of the legendary item which humans had worked so hard to perfect. Once you've managed to get hold of the armour, the next problem is to seek out the various items which will make you even more magnificent - anti-grav boots, particle negator, pulser beam and implosion mine are the vital elements. The implosion mine is perhaps more important than any of the other items. This is the object needed to destroy the aliens' base.
