Set in an art museum, this is an asymmetric competitive death game where players are divided into the "Guard Side (Detectives/Police)" and the "Recovery Side (Phantom Thieves)" to fight over hidden treasures. Basic Information Game Type: Competitive / Asymmetric Survival Game Total Players: 60 (Detective Side: 40 / Phantom Thief Side: 20) Stage (Venue): Art Museum Issued Weaponry: 6-shot revolver (common to all players) Issued Outfits: Costumes corresponding to each faction (detective suits, police uniforms, phantom thief attire, etc.)

Game Rules & Victory Conditions While it has aspects of a team battle, it is essentially an individual battle where "personal life or death" is at stake. Detective/Police Faction (Guard Side: 40 players) Tasked with protecting the "treasures (exhibits)" within the museum from the phantom thieves. Clear (Survival) Condition: Protect the treasures until the end of the game. Penalty: Every time a treasure is stolen (taken outside the building), a random player from the Guard team is killed. 怪盗陣営 (Recovery Side: 20 players) Tasked with stealing the treasures hidden or displayed within the museum. Clear (Survival) Condition: Successfully take at least one treasure outside the museum (to a designated exit). Faction Advantages: "Hidden entrances" and "secret escape routes" available only to the phantom thieves are prepared in advance. Special Notes Asymmetric Balance: Numerically, the Detective side (40) seems to have the advantage, but the Phantom Thief side (20) has structural advantages like hidden passages. Linked Death Penalty: Due to the penalty when a treasure is stolen, the Detective side constantly carries the risk of "dying unfairly even if they made no mistakes, simply because they failed to protect the treasure." Therefore, the Detective side is forced into perfect collective coordination.
