Murder Mystery 2 has been one of Roblox's most-played games since developer Nikilis launched it in 2014, and players still hunt for codes hoping to snag a free knife skin or cosmetic. The honest answer heading into April 2026 is that there are zero active codes right now. There haven't been any since late 2017, according to tracking by Twinfinite. That's a long drought. Still, knowing the full picture, including every expired code and exactly where to watch for new drops, puts you ahead of the crowd if something does land.
Are there any active Murder Mystery 2 codes?
No. As of April 2026, there are no working MM2 codes. Multiple sources, including Beebom, Twinfinite, and PCGamesN, confirmed this after checking in the first week of April 2026. The game continues to receive updates and stays popular, but Nikilis has not released a new code in years.
warning
Any site claiming to have active MM2 codes right now is either outdated or misleading. Every code listed below is expired and will not work.
Twinfinite notes one exception worth mentioning: the code FL4M (Flamingo Knife) appears in their database, but its active status is unconfirmed and it may have expired without wide documentation. Treat it as expired unless you can verify it yourself in-game.
Every expired MM2 code and its reward
All of these codes were distributed between 2015 and 2017. Entering them now will return an error. The table below is sourced from G2A, Twinfinite, and Beebom cross-referenced for accuracy.
Every reward here is a knife skin or cosmetic pet. No codes ever gave in-game currency or gameplay advantages, which lines up with how MM2 handles progression generally.
How to redeem Murder Mystery 2 codes
When new codes do arrive, you'll want to move fast. Codes in MM2 are redeemed per account, and each code can only be used once. Here's the process, confirmed across all sources:
- Launch Murder Mystery 2 on Roblox.
- Once in the lobby, click the Inventory icon on the left side of the screen.
- Look for the Enter Code box in the bottom-right corner of the inventory panel.
- Type the code exactly as shown, including numbers replacing letters (typos will cause it to fail).
- Click Redeem to claim your reward.
info
Copy and paste codes directly rather than typing them manually. MM2 codes use number-for-letter substitutions like 3 for E and 0 for O, which makes typos easy.Why doesn't MM2 have codes anymore?
Nikilis has not publicly explained the absence of new codes. Based on the pattern documented by sources like Beebom and Twinfinite, the last confirmed code drop was HW2017 for Halloween 2017. That's over seven years without a new one. The game itself keeps getting content updates, which suggests the decision to stop releasing codes was intentional rather than the game being abandoned.
G2A notes that when codes do appear in MM2, they tend to coincide with events, updates, or holidays. That's the window to watch.
info
Each MM2 code can only be redeemed once per account. There's no way to reuse a code, even if you missed it the first time around.
Where to watch for new MM2 codes
If Nikilis ever drops a new code, these are the places it will show up first:
- X (formerly Twitter): Follow @NikilisRBX directly. This is the primary channel the developer uses for announcements.
- YouTube: The official Nikilis YouTube channel occasionally posts game updates.
- Discord: The MM2 Discord server is where community announcements land. Joining it costs nothing and puts you in the right place.
- This page: Bookmark it. Sources are checked weekly.
For a broader look at what's currently redeemable across Roblox, VG247 maintains an updated MM2 codes tracker that pulls from the developer's official channels. BlueStacks also keeps a running list, and their Murder Mystery 2 codes page confirms the same no-active-codes status as of April 2026.
info
Codes in MM2 disappear fast when they do drop. Having the redemption screen memorized means you can claim in under 30 seconds instead of fumbling through menus.
What rewards do MM2 codes give?
Every code released by Nikilis has given a knife skin or a cosmetic pet. No code has ever provided Robux, in-game currency, or gameplay-affecting items. The rewards are purely visual, which means missing a code drop doesn't hurt your ability to play, just your ability to flex a rare skin.
The rarest cosmetics from the code era include the Pumpkin Pet (from HW2017) and the Flamingo Knife (from FL4M), both of which are no longer obtainable through codes.
