Murder Mystery 2 Codes (September 2026)

Murder Mystery 2 codes give players free knives and pets that add cosmetic flair to rounds spent as the innocent, sheriff, or murderer. Redeeming a code takes seconds through the in-game inventory menu, and the rewards carry no gameplay advantage beyond looking good while you sneak or hunt.

Working Murder Mystery 2 codes

No codes are active in Murder Mystery 2 right now. Nikilis, the game’s developer, hasn’t released a new code in years, favoring seasonal events, crafting, and trading as the main ways players earn free knives and pets. This list will be updated the moment a new code goes live.

How to redeem Murder Mystery 2 codes

Code redemption happens entirely inside the game’s inventory screen. Follow these steps whenever a new code becomes available.

Launch Murder Mystery 2 on Roblox and wait for the lobby to fully load.

Click the Inventory option on the left side of the screen.

Find the code entry box and type the code exactly as it’s shown, matching capitalization and any numbers or symbols.

Click Redeem. A successful code adds the reward directly to your inventory, where you can equip it from the same menu.

Where new codes get announced

New Murder Mystery 2 codes, if and when they return, would appear first through Nikilis’s own channels rather than any third party. The official Murder Mystery 2 Discord server is the most direct place to catch an announcement, since code drops historically spread through the community within hours of going live.

Keep in mind that scheduled maintenance and content updates can temporarily affect code redemption even when a code is technically active, so if a valid-looking code fails to redeem, it’s worth trying again after the game finishes loading fully.
