From the publisher's website:

Crossroads is a new series from Plaid Hat Games that tests a group of survivors' ability to work together and stay alive while facing crises and challenges from both outside and inside. Dead of Winter is the first game in this series, designed by Isaac Vega and Jon Gilmour. It puts 2-5 players together in a small, weakened colony of survivors in a world where most of humanity are either dead or diseased, flesh-craving monsters. Each player leads a faction of survivors with dozens of different characters in the game. Dead of Winter is a meta-cooperative psychological survival game. This means the players are working together toward one common victory condition--but for each individual player to achieve victory, they must also complete their personal secret objective. This secret objective could relate to a psychological tick that's fairly harmless to most others in the colony, a dangerous obsession that could put the main objective at risk, a desire for sabotage of the main mission, or worst of all: vengeance against the colony! Certain games could end with all players winning, some winning and some losing, or all players losing. Work toward the group's goal but don't get walked all over by a loudmouth who's only looking out for their own interests!
