This expansion introduces a fifth round of play, featuring a fresh card deck, an Arctic Tundra drinking spot, a 'cold die' that implements the new Cold Level system, an updated player reference guide, and supplementary rules for single-player mode.

In Arctic Tundra, creatures fight to sustain viable numbers amidst unforgiving conditions where intense cold threatens all forms of life. The Arctic Tundra module captivates players who seek punishing gameplay challenges.
