Murder Mystery 2 Wiki — Knives, Trading & Role Guides

Each round assigns exactly one murderer, exactly one sheriff and everyone else as an innocent. The murderer wins by killing the lobby before the timer ends, the sheriff wins by shooting the murderer, and innocents win by surviving. When the sheriff dies the gun drops on the floor and any nearby innocent can pick it up, so a round is never decided the moment the sheriff falls.

Most knives come from mystery boxes opened with keys earned through play, and limited-time bundle game passes pair a godly knife with a matching godly gun and an effect. Trading is the third route and the fastest way to fill gaps in a collection. The game itself does not publish an official rarity list, so rarity tiers come from community value trackers.

A trade is built inside the in-game window from both players inventories. Community value lists are the shared reference, but value and demand are different: a knife can be expensive and still slow to move. Never trade outside the game window and never follow a link from a trader, because the recurring scams all start by moving the conversation off-platform.

The rotation reported by players includes Bank 2, Bio Lab, Factory, Hospital 3, Hotel 2, House 2, Mansion 2, Mil Base, nStudio, Office 3, Police Station, Research Facility and Workplace. Maps are numbered by revision because earlier versions such as Bank 1, Hospital 1 and 2, Hotel 1 and the original Milbase were retired. This list is community-reported rather than an official published table.

It depends on which model you want. Bundle passes ship a godly knife, a matching godly gun and an effect, single-weapon passes sell one weapon, and EVO knives start at Rare and evolve as you earn XP while using them. Battle passes reward play instead of spending. The pass text itself warns buyers not to delete a game pass and notes a second knife copy can be bought in the in-game shop.

The Halloween 2026 update brought the Emberscythe, Emberbow and Embersickle weapons along with the Mortal Knife and Immortal Gun, plus a battle pass, an event mystery box, a Bingo Board, daily quests, trophies and lobby secrets. Event rewards arrive through several routes, so it is worth comparing the bundle price against the unboxing and battle-pass routes before spending Robux.

MM2 has been live since 18 January 2014 under developer Nikilis, and its cadence is event-driven rather than weekly: the biggest content drops land around seasonal events. The October 2026 snapshot puts the game at roughly 31.4 billion visits with about 270,000 players online. Smaller balance changes can land between events without a full patch note.
