MM2 codes are not giving items right now. There is no confirmed working code in Murder Mystery 2, and the old knife codes such as C0RL, SK00L or HW2017 are from years ago. The code box is still in your inventory, so it looks like it should work. Below is what each old code gave, why some lists still call them active, and the free routes to knives and guns that work every round.
Is there a working MM2 code
No code is confirmed active. A few code pages still show C0RL, D3NIS, SUB0, SK00L and HW2017 as working, while others list the same codes as expired. When the sources do not agree, the safe answer is that the code does not work, and if you want to try, typing it costs you nothing.
Nikilis, the developer, has not posted a new code in a long time. A monthly list of “new MM2 codes” is just the old ones in a different order.
Every old MM2 code
| Code | What it gave |
|---|---|
| C0RL, D3NIS, SUB0, SK00L, AL3X, PATR1CK | Knives named after YouTubers and the developer’s friends |
| R3PT1L3, PR1SM, N3ON, INF3CT3D, SK3TCH | Themed knives |
| COMB4T2 | Combat II knife |
| HW2017 | Pumpkin pet, the only pet ever given by code |
| F1RSTC0D3, 2015, B4CK2SK00L, N3XTL3V3L | Early event items |
If you want one of these items today, the only way is trading with a player who owns it.
How the MM2 code box works
- Open Murder Mystery 2 and go to your Inventory.
- Find the EnterCode box in the bottom right.
- Type the code, capitals and zeros exactly as written, and press Redeem.
MM2 codes use numbers in place of letters: 0 for O, 1 for I, 3 for E, 4 for A. Typing CORL with the letter O will never work. On PlayStation the box is missing.
The free way to knives: coins and crates
Every round drops coins on the map. You can collect up to 40 per round, or 50 with the Elite pass. A Mystery Box costs 1,000 coins. The game shows the odds for each box, and a Godly is rare, about 0.2 percent in the first box, so think of crates as a long collection, not a quick win.
- Collect coins as Innocent. You have the most time to roam.
- Stay alive. Dying early ends your coin collecting for that round.
- Recycle duplicates. Duplicate weapons turn into fragments of the same rarity, and fragments craft new items.
Trading safely
Trade only with the in-game trade window, where both sides see the items before accepting. Never accept “give first and I will send it later”, never trade for Robux outside Roblox, and never log in to a site that promises free Godlies. Those are the most common ways MM2 accounts are stolen.
Where a new code would show up
If Nikilis releases codes again, they will appear on the developer’s official X account and in the game’s Discord, usually tied to a big update or the Halloween and Christmas events. Until then, the code box is a museum.
Events: the real free knives
Halloween and Christmas are when MM2 gives the most. Events bring their own currency that you collect by playing rounds, and that currency buys event knives, guns and pets without Robux. If you play MM2 only a few weeks a year, make it those weeks.
Level up
Every round gives XP, and levels show your progress to other players. Surviving and winning rounds as Sheriff or Murderer gives more than dying early.
Know values before you trade
Players trade using community value lists. Check a value before you accept: a Godly that looks fancy can be worth less than a plain old knife. Never rush a trade because the other player says the offer ends in seconds.
How to collect more coins per round
Learn the maps. Coins spawn across the whole map, and the corners and upper floors are often empty of players. As Innocent, keep moving along walls and away from groups, where the Murderer looks first. As Sheriff, collect while you watch, and shoot only when you are sure. A full bag of 40 coins every round is what turns a free account into a box opener.
Frequently asked questions
Why does Redeem do nothing
The code is no longer active. There is no error message, the box just does nothing.
Is there an MM2 code for a Godly
No. No public code has ever given a Godly.
Can I get the Pumpkin pet now
Only by trading. HW2017 was a Halloween 2017 code.
When is the best time to get free items
During Halloween and Christmas events, when event currency buys knives and pets.
