August 4, 2026: Following the release of the Summer update, some people have claimed that there are new MM2 codes. However, this is not true, and these codes don't work when entered into the game. We have checked and verified this, and there are still no working Murder Mystery 2 codes.
Murder Mystery 2 codes are still desired by the game's thousands of players, which isn't surprising given they are mentioned in several places across the experience. Unfortunately, these are just references left over from a bygone era, as there have been no new MM2 codes for some time now.
MM2 is still hugely popular among the Roblox community, so there are always fresh faces arriving who don't know the history behind these mysterious codes. There are also often false claims that codes have returned, which isn't helped by the lingering presence of a codes redemption box in-game. With all this in mind, here's the latest update on MM2 codes.
While it's disappointing, there are still plenty of blanket Roblox promo codes that can be claimed for cosmetic items to add to your avatar across experiences.
Murder Mystery 2 codes
There are currently no active Murder Mystery 2 codes available, though there have been in the past.
As mentioned above, you can still see a sign within the game stating that if you're looking for free item codes then you should follow developer @NikilisRBX, however it has been years since they last revealed a promo and that account is largely inactive these days.
However, the creator did share in July 2026, following the release of the Summer update, that another huge update is on the way, so perhaps some new codes may be added in the future.
How to redeem Murder Mystery 2 codes in Roblox
While there are no MM" codes right now, there is still a codes redemption box in-game.
When Murder Mystery codes were available, you would need to open the Inventory menu and then type them into the EnterCode box before hitting the Redeem button.
However, at the time of writing this process appears to have been disabled, as there's no response when you press the Redeem button no matter what you type into the box. Furthermore, on newer systems such as Roblox on PS5 or PS4, the code entry box doesn't appear at all, adding further evidence that this feature may now have been permanently retired.
Expired Murder Mystery 2 codes
The following Murder Mystery 2 codes were valid at some point in the past, but all of them have since expired so the associated items can only be obtained by trading with other players, if you can find someone willing to part with them.
