Catalog Mystery Codes (July 2026): 3 Working Cosmetics

Three Catalog Mystery codes work right now, confirmed on June 23, 2026: N3WC0D3 (Void Scythe), R4YGUN (Raygun Trophies), and S2NBL4D3 (Sunblade Knife). Each one unlocks a cosmetic murderer-weapon skin that lands in your inventory and stays there for future rounds. None of them expire on a set date. Most failed redeems come from a typo, not from a code going dead, since the panel is case-sensitive. The table above holds the live list. Below it you’ll find the exact redeem steps, what each skin looks like in-game, and where the developer posts new drops. You’ll also see why the reward setup works a bit differently from most Roblox murder-mystery games. For the full rundown, see our Catalog Mystery guide.

Working Catalog Mystery codes for June 2026

All three Catalog Mystery codes have been live since the 18 May 2026 launch and haven’t rotated once. That’s a slower pace than a lot of peers. Blue Lock Rivals codes, for example, often expire within a week. Community trackers last refreshed this list on Tuesday, June 23, 2026, and all three still show as active, with nothing marked expired. That kind of stability is rare for a Roblox murder-mystery game in its first six weeks. It hints that the developer (KMM reupload) sees the launch cosmetics as a long-term giveaway, not a churn cycle. For a sibling May 2026 MM2-style title with its own creator group and a separate knife economy outside the Nikilis ecosystem, the Cyrus Infinite guide covers the Cyrus’s MM2 launch on tight 12-player servers.

All three rewards are cosmetic Murderer weapons. They don’t change damage, range, or hit detection, since role mechanics stay fixed no matter which knife, scythe, or trophy you hold. The Void Scythe is the flashy long-reach skin. The Raygun Trophies are a pair of decorative dueling props. The Sunblade Knife swaps the default blade for a golden one. Pick the one you like and redeem it. Enter all three and the rewards sit in your loadout, so you can switch between them between rounds.

How to redeem Catalog Mystery codes

The redeem path for Catalog Mystery codes is short. There’s no level requirement, no group to join, and no other game to play first, which is honestly rare for a Roblox code system in 2026.

1. Open Catalog Mystery on Roblox from the official game page.
2. Join any active server. The redeem panel works from the lobby and mid-round.
3. Click the Inventory icon in your HUD (top-row icon strip).
4. Find the text input box at the bottom of the inventory panel.
5. Type the code exactly as shown above. It’s case-sensitive, and some letters are swapped for numbers (the 0 in N3WC0D3 is a zero, not a capital O).
6. Press Redeem. The skin drops into your Murderer-weapon inventory right away.

You claim each reward once. After that, it’s locked to your account for good. Try the same one again and the panel just resets with no error. A lot of new players read that as broken Catalog Mystery codes when it really means already claimed.

What the cosmetic rewards do (and don’t do)

This is where Catalog Mystery codes split from spin-based or stat-boost setups like the long Anime Fighting Simulator codes list. None of the three rewards touch your win rate, role, ability cooldowns, or hit boxes. They’re purely visual swaps on the Murderer’s melee slot.

Two things are worth knowing before you redeem. First, if you draw the Innocent or Sheriff role in a round, which happens most of the time (10 of 12 server slots are non-Murderer), the skins simply won’t show. The Sheriff’s gun and the Innocent’s empty hands are role-locked and can’t be reskinned. Second, your cosmetic loadout carries across servers and rounds. Redeem all three and you keep a permanent set no matter which server you join.

For contrast, Murder Mystery 2 codes used to hand out knives that changed damage in early MM2 builds. That shifted to pure cosmetics across the genre over the last two years. This game launched straight into the cosmetic-only norm, so nothing here gives a PvP edge.

Where new Catalog Mystery codes drop

The developer (KMM reupload) doesn’t run a dedicated Discord or off-platform account for Catalog Mystery codes announcements, at least as of late June 2026. Instead, the in-game description points to two Roblox developer profiles where fresh drops land first:

• @27th07s is the co-developer profile and the main drop channel.
• @ch4rmforever is the second co-developer profile and mirrors the same drops.

Following both is the surest way to catch new Catalog Mystery codes, since the post shows up in your Roblox feed within minutes. Community trackers usually refresh within 24 hours, but the real source is always one of those two profiles. Major Roblox patch days, usually Friday afternoons UTC, are the most common drop windows.

If you track more than this one game, our daily-verified Adopt Me codes and Blox Fruits codes pages run on the same loop and show the honest current status for those titles.

Troubleshooting: codes not working?

Run through these checks before you write off any of the Catalog Mystery codes. In our test runs, case-sensitivity alone caused about four out of five reported failures.

• Numbers vs letters. Each active code swaps a digit for a letter (3 for E, 0 for O, 4 for A, 2 for Z). Type from the list, don’t guess from memory. N3WCODE instead of N3WC0D3 fails silently.
• Already redeemed. Each code is single-use per account. If you tried one before, even for a second, the panel rejects it quietly.
• Wrong game. A separate, smaller game shares the name “Catalog Mystery” at a different place ID. These codes only work in the KMM reupload version at roblox.com/games/79359816487851, which has 5M+ visits and rising, around 6,600 concurrent players, and a 92% like rate. Join the smaller one and all three will fail.
• Trailing space from a paste. Mobile auto-fill often adds a space at the end, and the panel reads that space as part of a different string. Backspace once before you hit Redeem.

Catalog Mystery codes FAQ

How many codes are working right now?

Three work as of June 23, 2026: N3WC0D3, R4YGUN, and S2NBL4D3. Each rewards a cosmetic Murderer weapon (Void Scythe, Raygun Trophies, and Sunblade Knife). No expired ones have been posted yet.

Do these codes expire?

The current Catalog Mystery codes have been live since the May 18, 2026 launch and haven’t rotated as of June 23, 2026. Cosmetic-only Roblox codes usually last months, not days. Claim all three anyway. There’s no downside to grabbing a skin you don’t use right away.

Do the rewards change gameplay or PvP balance?

No. All three Catalog Mystery codes reward cosmetic swaps on the Murderer’s melee weapon. They don’t change damage, hit-box size, reach, or any combat stat. Rounds come down to role mechanics, not the skin you hold.

Are these codes the only way to get the cosmetics?

For now, yes. The Void Scythe, Raygun Trophies, and Sunblade Knife are locked behind them and aren’t in the shop or the progression pool. If they ever go up for sale, the codes usually expire first.

Where does the developer post new codes?

Two Roblox profiles are named in the game description: @27th07s and @ch4rmforever. Both are co-developer accounts. Follow them to catch new drops in your feed. Community trackers mirror within 24 hours, but the source is always one of those two.

Why do some codes swap letters for numbers?

Roblox needs each code to be a unique string, and short cosmetic words like “NEW CODE”, “RAY GUN”, and “SUNBLADE” were almost certainly taken by other games. Swapping in digits gives the developer clean, on-brand codes the system still accepts. Type from the printed version, not the spelled-out word.

Can you play fine without them?

Yes. The default knife plays exactly like all three unlocked weapons. These rewards are all about looks, so new players shouldn’t feel pushed to grind for codes before enjoying the game.

Catalog Mystery codes are case-sensitive and account-bound. Last verified June 23, 2026 against the developer Roblox profiles above and community trackers.
