Intervention

A dark ugly shape appeared close to Mars, and proceeded to wipe out the mining colonies there. It looked as if Earth would be next, so a probe was sent up to investigate - it disappeared in a puff of dust. The only hope mankind had was to approach the alien vessel undetected - which seemed to be an impossibility. A team of four very brave astronauts undertook the seemingly impossible mission, to pit their wits against an alien technology of immense power. If they didn't succeed, humankind would be assigned to the pages of history - an alien history, for that was all that would be left.
