Nature of the Beast: Polar vs. Prairie is a game of strategy that focuses on recruiting animals and gaining control of your playing field. The first player to fill his entire field with animals wins. Players recruit animals, promote leaders, purchase equipment, find locations, enlist legendary animals, and befriend human allies. Players also keep track of two tallies during the game: Favor and Fury. Favor indicates how much "pull" you have with humanity. Fury indicates how much of a threat humanity sees you as. Fury is gained by attacking your opponents. Gaining Fury can allow you to take advantage of sinister "Dark Nature" cards, but gaining too much can eliminate you from the game. This Battle Box features two 70-card faction decks: Prairie and Polar. Prairie Animals are clever opportunists. Polar Animals are pragmatic survivalists.
