Nuclear war plunged the Earth into an endless winter, and the civilization that survived the bombs has not survived entirely intact. You lead a group of survivors in an improvised colony, keeping them alive through extreme cold, regular encounters with mutant creatures and zombie swarms, and the persistent erosion of food and supplies. Frozen ruins surround the colony and may hold what you need, but exploration carries its own risks. Keep the colony warm. Make hard decisions about who gets what when there is not enough of anything. Every choice about loyalty and sacrifice shapes whether the group survives or fragments.
