No MM2 code works today. The community wiki says it plainly ("There are no working codes right now"), and the comments under every "new codes" video agree: "none of these work", "when I put them, it doesn't give me anything".
I know it is not what you wanted to read, but it saves you from typing in the same strings from a dozen videos. Below is the full list of old codes and what each one gave.
Why "working codes" videos don't work
Videos titled "NEW ALL WORKING CODES 2026" collect over a hundred thousand views, and the comments are full of "fakes". Two reasons:
- The old codes are expired, so the lists in the video just repeat them.
- Many videos mix in promo codes of third-party shops. Those are codes of a website, not of the game.
A promo code from an item shop is a discount or a bonus inside that shop. It does not work in MM2, and a shop that sells game items for money breaks the Roblox rules.
How codes worked
Codes were a small reward system, like promos. A player typed a short string into a field in the inventory and, if the code was active, received an item. Most of the time it was a knife, but one code gave a pet. Codes were usually announced on the developer's Twitter page and sometimes on a YouTuber's channel.
Codes were active for a limited time. After that the code was disabled, and the item stayed with those who redeemed it.
All old MM2 codes
All of these are expired.

| F1RSTC0D3 | Gifted knife | Uncommon |
| R3PT1L3 | Reptile knife | Common |
| 2015 | 2015 knife | Common |

| N3ON | Neon knife | Common |
| INF3CT3D | Infected knife | Common |
| PR1SM | Prism knife | Common |
| AL3X | Alex knife | Common |
| C0RL | Corl knife | Common |

The spelling of some strings differs between sources, so do not treat the table as a typing guide. It is a record of what existed.
What is worth knowing about them
- Gifted and Reptile were the first code knives in the game. Gifted is the only code item that is uncommon.
- Pumpkin (2017) is the only pet that was ever given for a code.
- TNL is named after the Twitch series The Next Level, which several Roblox employees ran from 2014 to 2016.
- Skool came out when students went back to school.
- Alex, Corl, Denis, Sketchy and Sub are based on the members of a popular Roblox YouTuber group.
- Combat II is the first and only code of Season 1. The developer released it on 2 May 2020 after many players asked for a new code knife.
Code items are common, so their value is low. Old ones are still fun to collect, and you can find them through the common list.
Codes from toys: the other kind
Two unique guns came with real toys. The Nerf blasters Dartbringer and SharkSeeker included a code printed in the box, and entering it gave the matching gun in MM2. Those are Dartbringer and SharkSeeker. They were a promotion tied to the physical product, not a free code.
What to do instead of looking for codes
If you want items without paying, you can still get them:
- Play events for the battle pass, see how to get a godly.
- Open the daily box.
- Trade up from commons with the trade calculator.
Do not enter your Roblox password anywhere for a code. A page that asks for it is a phishing page.
