Mars: Grendel
The terraforming of Mars continues¸ with the inevitability of a giant machine rolling across the red dust of Sol's fourth planet... but there are still those who would like nothing more than to throw a planet-sized monkey wrench into that machine. The ecoterrorists (or preservationists¸ depending on your point of view) of Red Mars usually like their sabotage loud¸ flashy¸ and destructive - but this time they're trying something subtle. Can your Mars Defense Force team figure out who's the saboteur at the research station on the Hellas icecap - and where else their plans may lead? "Grendel" is written by Jim Cambias¸ author of GURPS Mars. (This is a digital reprint of a GURPS Third Edition product.)
