In space, all that matters is survival.
Renton and the crew set about getting Moon Base Delta back online. No simple task. Their efforts are further complicated by refugees arriving in from other areas of the Moon as the ongoing conflict for control of resources is making survival for those caught up in the crossfire almost impossible.
Yet without access to basic resources the colonists in the base can only survive for so long. They soon realize that if they are going to have any chance of surviving then they have no option but to fight for it.
