There are no working murder mystery 2 codes in June 2026 — every code ever released has expired, and the developer hasn’t issued a new one in years. That’s the short answer. The longer answer is more useful: MM2 still hands out free knives and pets, just through different systems, and knowing how the old codes worked helps you spot the fake “new code” videos that flood YouTube every month. This page covers the real history, the genuine expired list, and the methods that actually earn you items today. For an active MM2-format alternative built on the same 1-vs-All knife format, the Cyrus Infinite guide covers the survival game from the Cyrus’s MM2 creator group — 12-player servers, custom knife skins, and cross-game rewards.

What happened to Murder Mystery 2 codes

Codes were a real feature in MM2’s earlier years. Nikilis, the game’s developer, released short text codes — mostly through his Twitter/X account and through collaborations with YouTubers like The Pals — that players typed into their inventory for a free knife or pet. The MM2 wiki’s codes page documents the full run: it started with F1RSTC0D3 (the Gifted knife) and ended with COMB4T2, the Combat II knife and the only code released during Season 1.

After that, the pipeline simply stopped. The wiki has listed “no working codes” for years, and as of June 2026 nothing has changed — code trackers at PCGamesN and Pocket Gamer both confirm zero active codes this month. Nikilis shifted MM2’s free-item economy toward seasonal events, crafting, and trading instead, and there’s no announced plan to bring codes back.

So when you search murder mystery 2 codes today, what you’re really looking for is one of two things: the historical list (below), or the current ways to get free items without codes (further down). Both are here.

The real expired Murder Mystery 2 codes list

The table above shows the genuine codes from MM2’s history, as documented on the community wiki. All of them are expired — typing them into the game today does nothing. They’re listed for reference because plenty of sites and videos recycle these exact strings as “new working codes,” and recognizing them instantly tells you a source is recycling dead data.

A few notes on the list:

  • COMB4T2 was the last code ever released. Nikilis added it during Season 1 after sustained community demand for one more code knife.
  • HW2017 (the Pumpkin pet, Halloween 2017) was the only pet ever distributed by code — everything else was a knife.
  • AL3X, C0RL, D3NIS, SK3TCH, and SUB0 were a themed set based on The Pals, the YouTuber group, released around their MM2 collaborations.
  • F1RSTC0D3 gave the Gifted knife, the only uncommon-rarity code item; every other code knife was common rarity.

A handful of other real codes existed too — R3PT1L3, PATR1CK, B4CK2SK00L, G003Y, N3XTL3V3L, N3ON, PR1SM, and the literal code 2015 — all common knives, all equally dead. If you see any string outside this documented set advertised as an MM2 code, it was never real.

How redemption worked, and how to test a claimed code

When codes were live, redemption happened in the lobby: open your Inventory, find the code entry box, type the code exactly, and confirm. The box still exists in the interface, which is part of why rumors persist — players see an input field and assume something must work in it.

If you ever want to verify a claimed code yourself, that’s the test: open Murder Mystery 2 on Roblox, paste the string into the inventory code box, and see what happens. Every claimed code in June 2026 returns an invalid/expired result. The only source that would matter for a genuine new code is Nikilis’s own X account — a real drop would spread through the community within hours, and you would not need a YouTube thumbnail to find it.

How to get free knives and pets without codes

This is the practical replacement for murder mystery 2 codes, and the systems are better than the codes ever were — code knives were almost all common rarity, while these methods can reach legendaries.

  • Coins and boxes. Every round you play, you collect coins on the map. Coins buy weapon and pet boxes in the shop. It’s the slow-and-steady baseline — innocent rounds spent looting coins add up faster than most players expect.
  • Crafting. Open your inventory and enter the crafting station (the “view” button at the bottom right). You salvage duplicate weapons into crafting materials, then craft them into a random uncommon, rare, or legendary weapon — even a seer or painted seer. If your inventory is full of duplicate commons, this is the single best free upgrade path in the game.
  • Trading. Once you reach level 10 (a requirement added in December 2021 to fight duping), you can trade weapons, pets, and miscellaneous items with other players. Smart trading compounds: a few good swaps turn box-luck commons into a respectable inventory. Check our Murder Mystery 2 tier list before accepting any trade so you know what your items are actually worth.
  • Seasonal events. Covered in detail below — these are where the genuinely free, genuinely good items live now.

Trading value basics

Item value in MM2 isn’t a single number. The community measures it across base value, demand, rarity, and stability — a “rare” tag alone doesn’t make something tradeworthy if nobody wants it. Effects, emotes, and radios can’t be traded at all, so don’t bank value in those categories.

Two beginner rules cover most mistakes. First, never trade based on rarity color alone; demand moves prices more than tier labels do. Second, event items tend to appreciate after their event ends, because supply is capped forever. That’s the full extent of what this page will say on value — for per-item rankings and which knives are worth holding versus flipping, the Murder Mystery 2 tier list is the dedicated guide, and the Murder Mystery 2 game hub collects everything else we’ve written about the game. The same demand-over-rarity logic drives every Roblox trading economy — the Adopt Me tier list ranks pets on the same principle, where 2019-era event legendaries sit at the top purely because their supply is frozen forever.

Seasonal events: where free items actually come from now

Events are the real successor to the code system. Nikilis runs them on a recurring calendar — the wiki documents the Christmas Event 2025 and the Valentines Event 2026 as the most recent — and each one introduces an event currency you earn by playing during the event window, then spend on limited knives, guns, and pets. Halloween and Christmas are reliably the biggest drops of the year.

The catch is the window: when an event ends, its items become unobtainable except through trading, which is exactly why event items hold and gain value. If you’re playing in June, the practical advice is to stack coins and crafting materials now so you can convert playtime into event items efficiently when the next event lands in the fall.

If you’re collecting codes across Roblox more broadly, the code systems in other big games are still fully active — see our Adopt Me codes (game hub), Blox Fruits codes and the Blox Fruits tier list for fruit rankings, Blade Ball codes, Pet Simulator 99 codes and Pet Simulator 99 tier list, Grow a Garden codes, Anime Story 2 codes, DOORS codes (the Doors game hub collects all Doors content — codes, monsters guide, and walkthrough — in one place), and Bee Swarm Simulator codes pages — each with its own current active list. Bee Swarm Simulator is the most striking contrast to MM2’s retired system: 13 codes are working as of June 2026, including seven that have been redeemable continuously since 2018. If the Innocent / Sheriff / Murderer roles format itself is what you’re here for, the Catalog Mystery guide covers a newer Roblox roles game that uses the same three-role structure across three distinct game modes — and the Catalog Mystery codes page lists three live cosmetic-unlock codes, unlike MM2. See the Catalog Mystery game hub for all related content and game stats. Beyond Roblox, the 007 First Light hub covers IO Interactive’s Bond spy-stealth game — the site’s first non-Roblox title.

Murder Mystery 2 codes FAQ

Are there any working Murder Mystery 2 codes right now?

No. As of June 11, 2026, there are zero working murder mystery 2 codes. The MM2 wiki, PCGamesN, and Pocket Gamer all independently list no active codes, and the last real code released was COMB4T2 during Season 1.

Will Murder Mystery 2 codes ever come back?

Nothing is announced. The code input box still exists in the inventory UI, so the system could technically be revived, but Nikilis has favored seasonal events over codes for years. If a new code ever drops, it will appear on his X account first.

Why do YouTube videos claim new MM2 codes every month?

Because “murder mystery 2 codes June 2026” gets searched constantly, and thumbnails promising free godlies get clicks. The strings shown in these videos are either the real expired codes from the list above or invented ones. None redeem.

What did codes give when they worked?

Almost entirely common-rarity knives — Alex, Denis, Prism, Infected, and similar. The two exceptions were the Gifted knife (uncommon, from F1RSTC0D3) and the Pumpkin pet (from HW2017, Halloween 2017).

What’s the fastest way to get a good knife without codes?

Salvage your duplicate weapons and craft toward a legendary at the crafting station, then trade up from there once you hit level 10. Use the Murder Mystery 2 tier list to avoid lowball trades.

For active knife-throwing gameplay on Roblox, the Splatter Knives Museum guide (game hub) covers the June 2026 action title where players throw knives through museum rooms for splatter scores — a contrast to MM2’s knife-trading economy.
