From the publisher's website:
"The Chinese research outpost called Minotaur Station has gone silent . . . and in the early days of Mars exploration, everybody planetside helps everybody else, because they're all you've got for several hundred million miles. But why are the Chinese rescuers so hostile? And just where did everybody go?"
"Rescue Mission is an adventure for the 'Domed Mars' setting in GURPS Mars, and it's written by GURPS Mars author Jim Cambias. Can you solve the mystery and watch your back in an environment so unforgiving that the tiniest mistake could kill?"
