About This Package
Trust No One. Survive the Night.
Murder Mystery is a social deduction multiplayer game where paranoia is your only companion. A routine gathering goes horribly wrong when a ruthless murderer hides among you.
Your goal? Work together to survive, gather clues, and unmask the killer before it’s too late. Or, if the knife has found your hand, eliminate everyone without a single witness.
Connect with our community on Discord for lobbies, updates, and to report feedback.
How It Works: The Roles
In every round, roles are assigned randomly. Your alliances are temporary, and every action is suspicious.
- Innocents - Keep your head down and stay alert. Your main tool is observation. Collect coins around the map and buy pistol. Study everyone’s behavior, help the Sheriff piece together the truth, and just survive.
- The Detective - Armed with the only pistol. It’s your duty to protect the Innocents and take down the Murderer. But be extremely careful: a single misstep or a shot at an Innocent will cost you your own life.
- The Murderer - Arm yourself with a knife and a perfect alibi. Blend in, create chaos, and pick off targets one by one. Use the environment, the dark, and your best lies to deflect suspicion and remain undetected.
Key Features:
- Social Deception & Bluffing: Communication is key. Use in-game voice chat to plant seeds of doubt, make false accusations, and coordinate your defense or attack.
- Dynamic Environments: Navigate varied maps with secret passages, vents, and clever places to hide your evidence (if applicable).
- Quick, High-Tension Rounds: Experience quick, intense matches with constant action and heart-pounding suspense.
- Customization: Win rounds to earn currency and unlock new cosmetic knife skins and special nick effects.
