Mysterious Murderers Codes
Working promo codes, expired archives, and a full redemption walkthrough for Granturismo Games' murder-mystery Roblox title.
Mysterious Murderers is a Roblox murder-mystery experience from Winng3447 and Granturismo Games, released on 15 April 2026. Up to 12 players per round take on the roles of Murderer, Sheriff, or Innocent—and promo codes are one of the fastest ways to unlock cosmetic weapons, currency, and special items without spending Robux. This hub collects everything you need: what is still working, what has expired, and exactly how to redeem rewards in-game.
Codes in Mysterious Murderers are case-sensitive strings entered through the Inventory menu on the left side of the screen. Rewards typically land in your inventory immediately, though server lag or an already-claimed code can make it look like nothing happened. Because the developers rotate promotions around updates and seasons, treat every list—including ours—as community-tracked: always verify in your own lobby before you share a code with friends.
What codes give you
Most active codes reward melee skins, gun cosmetics, coins, or utility items like the Mystery Key. Seasonal strings such as SEASON4 have handed out large coin bundles, while weapon-themed codes like OCEAN, LAVA, and FUTURE unlock themed swords, hammers, and laser gear that stand out in the lobby. These items are generally cosmetic or inventory flair rather than direct gameplay buffs, but they help you personalize loadouts across Murderer and Sheriff rounds.
Granturismo also ties some rewards to community milestones. Joining the official Granturismo Games Roblox group and helping the community reach 50,000 members unlocked the Free Chroma milestone reward—separate from typed promo codes but worth claiming if you have not already. Group perks and code redemptions both flow through the same Inventory system, so once you learn the menu once, every reward type feels familiar.
Where to go on this wiki
Use the pages below instead of scrolling random social posts—each one is maintained for a specific job:
- Active Codes — the full working list with reward names, notes on uncertain codes like FR33C4ROMA and PINK2, and tips for double-checking status after patches.
- Expired Codes — a historical archive so you stop re-typing dead strings such as ICE, PO1S, and UPDATEHYPE.
- How to Redeem Codes — step-by-step redemption with troubleshooting when the Enter Code button greyed out or rewards fail to appear.
- Codes Checklist — track which promos you already claimed so you do not waste lobby time re-typing dead strings.
Some community strings need a live-server test before you share them — CWAVES, EGUN, EKNIFE, and COCEAN flip with patches more often than staples like SEASON4 or OCEAN. Use the checklist tool after each successful redeem and cross-check Active Codes when a verify code fails on one server but works on another.
If you are new to the game itself, pair this section with the Getting Started guide for role basics and the Sheriff guide or Murderer guide once you know how redemption works.
How often codes change
Mysterious Murderers receives updates tied to seasons, maps, and weapon drops—Season 4 codes appeared alongside broader content pushes, and limited strings often expire quietly after a few weeks. Developers sometimes re-enable fan-favorite rewards for events, but never assume an expired code will return. When a new trailer or update drops, check Active Codes first, then skim Expired Codes so you recognize renamed or replaced promotions.
Bookmark this hub if you play regularly. Murder-mystery sessions are short, and missing a single active code can mean losing a free knife skin before the next balance pass. We update tables when the community confirms changes in-game— not from rumor threads alone.
Quick redemption reminder
Open Inventory (left side) → Enter Code → type the string exactly → Redeem. Copy-paste when possible; swapping a letter for a look-alike number is the most common failure. One code per account unless stated otherwise. If you need screenshots and fixes, the dedicated How to Redeem Codes page walks through mobile and desktop layouts.
Not Murder Mystery 2
Search results often confuse this game with Murder Mystery 2. Mysterious Murderers is its own Roblox title with separate codes, maps, and creators. MM2 codes will not work here. For a full comparison, read Mysterious Murderers vs Murder Mystery 2 on our Links hub.
