Crash landing!
After a rowdy victory celebration following the battle of Europa, Bob goes for a stargazing trip out in the desert and wrecks his speeder. Stranded, he soon finds that he isn't alone. Harbeasts, the savage, fearsome, genetically engineered predators that roam the Martian deserts are hot on his trail!
With no water, no food, limited air supply, no working vehicle and the nearest way-station days away, Bob finds himself in a dogged fight for survival. Unfortunately, Bob soon finds that the harbeasts aren't the only predators out to get him!
