Today we bring you the Roblox MM2 codes with the most up-to-date list of codes that you can redeem for free knife skins. These codes don’t do much in the game, but collecting different knife skins is one of the most fun aspects of playing MM2, so don’t miss out on them.

In Murder Mystery 2 you will take on the role of an innocent, a sheriff or a murderer, the innocent must run, hide and evade the murderer and hopefully eventually use their detective skills to find out which player is the murderer. The Sheriff seeks to work with the innocent to find out who ends up being the Killer. If you’re the Sheriff, you’ll be the only other player with a weapon, so you can take down the Killer if you find out who he is. The Assassin is the main baddie of this scenario and seeks to eliminate any player who crosses his path. You’ll want to try to be sneaky so you don’t get caught and get shot by the Sheriff.

Redeeming codes in Murder Mystery 2 is quite easy. On the side of the screen while in the lobby, look for the inventory button. Click on that and you will get a popup window. At the bottom right of this window, you will see the EnterCode area with the Redeem button below it. Click “EnterCode” and enter one of the codes below. Once you have entered it correctly, you will only have to press the Redeem button and you will receive the reward. If the code is valid, the button will be displayed in blue.
