Update: Checked for new Murder Mystery 2 codes on June 05, 2026.
Murder Mystery 2 is a Roblox game where each round assigns players one of three roles — innocent, sheriff, or murderer — and survival depends on reading the room before it's too late. Developer Nikilis periodically releases promo codes that reward free items, mostly knives with unique designs, directly to your account.

MM2 codes are case sensitive, so enter each one exactly as it appears above — a single wrong character will prevent it from going through.
How to redeem MM2 codes
Step 1: Open Murder Mystery 2 on Roblox and wait until the game has fully loaded.
Step 2: Click the Inventory icon on the left side of the screen. It's the first icon on that panel and is labeled "Inventory" — it resembles a wooden crate.
Step 3: Find the field labeled "EnterCode" in the bottom right of the Inventory panel. Type or paste your code into that box and press Redeem. A confirmation message will appear on screen once the reward has been credited to your account.
