Secret Game: Killer Queen Portable

13 people are locked inside an abandoned building, none of them remember how they got there. Each has a PDA representing a playing card from A to K and a collar device locked around their necks. Each of the 13 PDAs correspond to a different set of objectives ranging from simply surviving to eliminating everyone else. If a player fails to fulfill their PDA’s objective within 72 hours or breaks any of the game’s rules, their collar will activate and they will die.
