Masters of Mayhem is a free-to-play social deduction game with roguelike twists for 4–15 players. Players work together to restore abandoned facilities and contain terrifying monsters — unless you're an impostor, in which case you unleash mayhem. The core gameplay loop revolves around asymmetric objectives: Innocents complete tricky and tactile tasks while watching for suspicious behavior, while Impostors take out Innocents while remaining undetected. At the start of each game, you're secretly assigned the role of Innocent or Impostor, and only Impostors know who the other Impostors are.

The game distinguishes itself through its roguelike progression system layered atop traditional social deduction mechanics. Players mix and match abilities to create their own playstyle through roguelike perks every run. The game is stacked with environmental hazards and tools designed to maximize the mayhem. Players plead their case in voting rooms, frame others, share evidence and theories, and voted-out Impostors fall into the abyss but can still influence the game in the afterlife.

Two maps are available to explore—the frozen Arctic and ancient Temple, each hiding a monster the Impostors are plotting to unleash. The game supports 4–15 players with public and private lobbies, or matchmaking queue options. Vibrant characters feature unique lore, animations, and personality.

Masters of Mayhem is built by Super Studios, led by industry veteran Rick Ellis (Valve, Team Fortress, Half-Life 2). The title appeals to players seeking social deduction gameplay with mechanical depth—combining the deception and discussion elements of party games with roguelike progression and environmental interaction. It's designed for groups seeking cooperative gameplay with built-in conflict, making it ideal for friends and streamers alike.
