Personally finds and maintains every code on this page, with around-the-clock help from the rest of our Code Guardians.

Roblox Den's code tracker continually scans Roblox.com, social channels, user reports, game developer networks and other sources, and we've had 731,015 reports from players on Works, Doesn't work and new codes. But before any code is listed on our site, or marked as Expired, our Code Guardians check in-game that it works and that its rewards and requirements are right. That's why every code you try on Roblox Den works.

  1. Checks every code in-game

    Nicole tests every new Murder Mystery Duo code in-game, and re-checks any code that enough players report as not working.

  2. Keeps this page up to date

    When Murder Mystery Duo changes how codes are claimed, adds a new requirement or launches a new promotion, Nicole makes sure it's covered here first.

  3. Lists exact rewards and requirements

    Every code shows exactly what it gives and any level or gamepass it needs, so you know what you're getting before you redeem it.

Nicole isn't the only Code Guardian around here: Erwin and Renato check new codes for this game whenever Nicole is away or asleep.

About Murder Mystery Duo

Murder Mystery Duo is a thrilling multiplayer Roblox game where each player is randomly assigned one of three roles including, Innocent, Murderer, and Sheriff.

The Innocent players must escape the Murderer who is trying to kill them. They can also help the Sheriff catch him. The Murderer’s goal is to kill all Innocents and avoid the Sheriff. And lastly, the Sheriff must catch the Murderer and protect all Innocent players.

There’s a slight twist in this Murder Mystery game where players can also open cases and collect various weapons and items. You can trade these items and gain an advantage depending on your current role.
