Dead of Winter is a meta-cooperative psychological survival game. This means players are working together toward one common victory condition — but for each individual player to achieve victory, he must also complete his 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 looking out only for his own interests!
Dead of Winter has players making frequent, difficult, heavily- thematic, wildly-varying decisions that often have them deciding between what is best for the colony and what is best for themselves.
