BUNKER is an intense social multiplayer survival game for 4–10 players where deception is your primary tool. Every player begins with a secret, dynamically generated Player Card that defines their role in the bunker, encompassing a critical set of attributes: Profession (Skill), Health, Psychological state (Psychics), and a Personal Item. Crucially, each player holds a unique, hidden Target Goal (e.g., "You must survive," "Everyone must die") that guides their negotiation strategy and determines their final win condition. The environment is set against a backdrop of a randomly determined global cataclysm, which shapes the final survival criteria, such as a Nuclear War or an Alien Invasion. The game progresses in rounds consisting of phases—Reveal, Discuss, and Vote—where players must use the integrated Push-to-Talk voice chat to form alliances and selectively disclose their attributes to prove their worth. Strategic depth is added by the optional Linear Mode (Turn Mode), which enforces a strict turn order during the critical Reveal Phase, muting all other players to maximize pressure on the acting player. Furthermore, each player is assigned a Super Ability, chosen from 17 powerful options, that can be used once per game to dramatically alter the characteristics of others—for example, "Genetic Experiment" to swap Health and Psychics, or "To rejuvenate" to lower a player's age. When a player is eliminated by the vote, they do not leave but become a Ghost, retaining the ability to move freely and express their frustration or approval using unique, non-verbal emotional animations. The final outcome is calculated based on the surviving group's collective traits against the backdrop of the set apocalypse scenario.
