In this first expansion for Arctic Scavengers, the concept of tribe leader roles is added, providing each player with unique capabilities. Additionally, players each maintain a base camp (HQ) that can be upgraded adding an additional dimension to the game. An official 2-player variant is included with this game. The game consists of a 54-card deck containing: 10 Tribe Leader roles (providing unique player powers) 4 Buildings to flesh out your headquarters 3 Gangs (end-game victory condition similar to Catan's 'Largest Army' or 'Longest Road') 2 Mercenaries (Medic and Engineer) 2 New Tools (Rifle and Toolkit) A handful of additional Pills and Medkits (to balance out the new tools and keep the ratio in check)
