Alpha Prime

Somewhere deep in space, hidden in the infinity of the Universe, there is
a treasure trove just waiting to be opened by the eager hands of a daring
explorer. A mere asteroid, a piece of rock, a speck of dust lost in the
boundless void, yet priceless to humanity. For under its frozen crust there
are rich veins of the most precious substance known to man - hubbardium.
This "liquid metal" is a key ingredient in the fuel of interstellar ships,
thus enabling mankind to spread across the Universe from its base on Earth.
Its importance is the reason why it is monopolized by the State Business
Federation, a huge multinational corporation which is given control over
every single step in production of hubbardium, from exploration to
distribution.

And so, when this asteroid, subsequently named Alpha Prime, and its fabulous
riches were discovered, the Corporation quickly came, and a huge, sprawling
base was promptly built on its surface as the giant mining machines begun
its work.

But all was not well on Alpha Prime. While its hubbardium veins might be
plentiful, some of them were also dangerous. They slowly intoxicated the
minds of human workers, and damaged the positron brains of the artificial
ones, including the central computer. Conditions on the base became highly
unstable and the Corporation finally decided to seal off the entire facility
and leave......

Now, illegal visitors have seized control of the facility... and it's down
to you help sort out the situation...
