Hidden information: cards are mostly face down. If you look at something, it's
up to you to tell the others!
Semi-cooperative gameplay: there can be multiple winners or even none.
Everyone plays for their own survival, but you'll need to cooperate.
Condition system: health condition cards in your hand give clues about your
future. But you can never be sure about which one is going to be activated.
Several game modes: play the classic Semi-coop, try the game in Solo mode,
or survive in Full co-op or the competitive "Last Man Standing" game modes.
