Murder Mystery 2 on Roblox has used limited-time codes in the past to hand out free knives, guns, and even a Halloween pet. In January 2026, however, there are no working codes, and every known promo has expired.
Current Murder Mystery 2 codes (January 2026)
As of January 2026, there are no active, redeemable Murder Mystery 2 (MM2) codes. The game has gone several years without a new promo, and all historic codes that once granted knives or pets are now disabled.
The Inventory screen in MM2 still shows the EnterCode box and Redeem button on platforms that support it, but entering any of the old codes will only result in an “Invalid” or “Expired” message.
There is also a strong indication that on some platforms (such as console versions of Roblox) the code entry field no longer appears at all, suggesting that the system is effectively retired even though the UI may linger on other devices.
Expired Murder Mystery 2 codes and rewards
MM2 used to rotate through a series of promos that primarily unlocked cosmetic knives for the Murderer role and, in one case, a seasonal pet. These codes now all show as expired in-game and cannot be redeemed.

On some regional guides, an additional code FL4M is listed for a Flamingo Knife. In practice this behaves like the other promos and no longer redeems in-game.
These knives and the Pumpkin pet now only exist in the trading ecosystem. Players who redeemed them years ago can still use and trade them, which is why they are often treated as collectible, high-value cosmetics.
Why Murder Mystery 2 codes are no longer active
MM2 has a player-driven trading economy where rarity and demand determine the value of knives, guns, and other cosmetics. Community “value lists” track how desirable different items are, and older event or code rewards tend to rank highly because they can no longer be obtained directly.
Handing out new freebies through widely shared codes would immediately increase the supply of those items. If a powerful or sought-after knife were distributed to a large part of the player base overnight, its trading value would collapse. Limiting or stopping codes helps preserve scarcity and keeps trading meaningful.
Seasonal events such as Halloween and Christmas still introduce new knives and effects, but players are expected to earn those through gameplay or purchases instead of universal codes. That structure supports the long-term health of MM2’s economy.
How to redeem Murder Mystery 2 codes (when available again)
If the developer ever decides to re-enable codes, the redemption flow is straightforward. The Roblox experience link for MM2 is available at https://www.roblox.com/games/142823291/Murder-Mystery-2.
Step 1: Launch Murder Mystery 2 on Roblox and wait until you are fully loaded into the lobby. Make sure you are on a platform that shows the full Inventory interface.
Step 2: Click the Inventory button on the side of the screen. It uses a treasure-chest style icon and opens a window with tabs for knives, guns, pets, and other cosmetics.
Step 3: Look to the lower-right area of the Inventory window. When the system is enabled, you will see a small text field labelled EnterCode alongside a Redeem button.
Step 4: Carefully type a valid code into the text box, matching capitalization and numbers exactly, then press the Redeem button once.
Step 5: If the code is active, a pop-up will show the new item and it will appear in the relevant Inventory tab. If the code is expired or invalid, the game will display an error message and no item will be granted.
Currently, pressing Redeem does nothing for any known code, and some clients do not show the EnterCode field at all. That behavior is consistent with the code system being shut down rather than temporarily empty.
How to get free MM2 items without codes in 2026
With promos inactive, progression in MM2 comes from playtime, trading skill, and community participation. Several approaches are widely used to build an inventory without relying on codes.
Play matches and grind coins. Regularly completing rounds as Innocent, Sheriff, or Murderer earns coins. Over time, these can be spent on in-game crates and shop items, which roll for knives, guns, and effects. Consistent play is the most reliable path for newer players who do not already have valuable items to trade.
Focus on seasonal events. Limited-time events around holidays introduce exclusive cosmetics that can become highly valued once the event ends. Actively playing during these windows, completing event challenges, and investing your event currency efficiently can yield skins that later serve as strong trade pieces.
Trade up intelligently. The core of MM2’s economy is trading. Many players start with low- or mid-tier items and negotiate incremental upgrades, using community value expectations as a reference. Being patient, avoiding panic trades, and learning which skins are stable or trending upward in value is often more important than any single code ever was.
Enter legitimate giveaways only. Streamers and community creators occasionally run item giveaways. When joining these, never share your password or enable anything that asks for off-platform login. A genuine giveaway only needs your Roblox username so a trade request can be sent while you are in-game.
Checking for any future Murder Mystery 2 codes safely
Because MM2 remains a popular Roblox experience, interest in “secret” or “new” codes is constantly exploited by scammers. The safest way to track any genuine future promo is to rely on official developer channels rather than random generators or suspicious links.
Developer communication for MM2 historically runs through the creator’s social media and the official MM2 community spaces. If new codes are ever reintroduced, they are expected to be announced clearly there, and they will redeem directly inside the MM2 Inventory screen as described earlier.
Anything that claims to generate unlimited knives, asks for your Roblox password, or redirects you through multiple unknown websites should be avoided. These schemes commonly lead to stolen accounts rather than free items.
For now, Murder Mystery 2 is effectively a no-code game in 2026. Building a strong inventory depends on playing matches, participating in events, understanding item values, and trading carefully with other players, while treating any claim of new universal codes with skepticism unless it comes straight from the game’s official channels.
