The expansion takes place on Sahal, a snow-covered volcanic archipelago covering an area of 83 square kilometers. With the new location, the game now has more complicated gameplay due to the climate — for example, there is a frostbite mechanic, and the proximity to volcanoes will threaten natural disasters. To survive, you will need to look for sources of heat and stock up on clothing. In addition, there are new types of animals and improvements for fishing.
