All Active MM2 Codes (November 2026)

Murder Mystery 2 codes work differently from most Roblox promo codes since they almost always reward a cosmetic knife rather than currency or stat boosts. That's why each one carries more weight than a typical code, a free knife can turn into one of the most sought-after items in the trading market once the code itself is gone for good.

Redeeming one takes seconds through the Enter Code box tucked inside the Inventory menu, though finding a working code tends to be the harder part. Nikilis has always tied releases to specific milestones or events rather than a fixed schedule, which keeps the trading economy from getting flooded with free items. In this article, we'll explore every active MM2 code and its reward, along with the exact steps to redeem them.

MM2 Codes

Murder Mystery 2 was created by Nikilis and has remained one of Roblox's most popular games since its launch, built almost entirely around collecting and trading knife skins. Codes have always played a small part in that setup, usually rewarding a single exclusive knife.

New codes are rare by design, since flooding the game with free knives would collapse their trading value. Most players today are far more likely to trade for an old code's reward than to see a brand new one appear.

Active MM2 Codes

Codes for MM2 don't stay live long once they drop, so the table below is the fastest way to check what's redeemable without digging through outdated lists.

Expired MM2 Codes

MM2 has released a small but memorable set of codes over the years, almost all of them tied to a single exclusive knife. None of the codes below still works.

HW2017 stands out as the only code on this list that didn't give out a knife, rewarding the Pumpkin Pet during Halloween 2017 instead. Every other code follows the same pattern, a single cosmetic knife tied to one release.

How to Redeem Codes in MM2

Redeeming a code in Murder Mystery 2 is a lot simpler than in most Roblox games, since everything happens inside a single menu without any traveling required.

1. Launch Murder Mystery 2 on Roblox.

2. Click the Inventory icon on the left side of the screen.

3. Find the EnterCode box in the bottom right corner of the inventory window.

4. Type the code exactly as it's written, since codes are case-sensitive.

5. Press Redeem to claim your reward.

Your knife or item should show up in your inventory right away. If the code doesn't go through, double-check for typos first, since that's the most common reason a valid code gets rejected.

Where to Find More MM2 Codes

Nikilis posts new codes through official channels rather than letting them leak out first, so following those directly is faster than relying on third-party trackers. The MM2 Discord server's announcements channel is usually the first place a code shows up, with the @NikilisRBX account on X picking it up shortly after.

The Nikilis YouTube channel is also worth keeping an eye on, especially around Halloween or Christmas, since past codes have lined up with those seasonal events more than any other time of year.

This page gets updated as soon as a new code is confirmed working, so checking back here saves you from cross-referencing multiple trackers every time.
