BETRAYAL MECHANICS
Systems that allow — or engineer — the breaking of trust: hidden traitor roles, alliance-breaking, backstab bonuses, coups, and defections, making loyalty itself a resource players manage.

Among Us builds an entire social genre on it: impostors perform cooperation while sabotaging it, and every discussion is a trial of credibility. Crusader Kings III systematizes betrayal at scale — vassals scheme, claimants press, and your own council will join factions against you, with hooks and secrets as the currency of leverage. Designers use betrayal to generate the strongest emotions multiplayer can produce (paranoia, vindication, outrage) and, in single-player, to make political worlds feel alive — a court that never plots is furniture. Betrayal also creates self-balancing politics: the leader attracts knives. Key decisions: whether betrayal is a designed role (dealt by the game, absolving the traitor socially) or a free choice (which can poison real friendships), what the mechanical payoff and reputation cost are, and how victims get counterplay — spies, tells, insurance. Pitfall: betrayal without cost or telegraph reduces trust to noise; if everyone always betrays because it's strictly optimal, the game loses the cooperation that made betrayal meaningful.
