Mysterious Murderers Expired Promo Codes
Historical code list for Mysterious Murderers—know what no longer works and where to find replacements.
Promo codes in Mysterious Murderers do not last forever. Granturismo Games rotates strings around updates, seasons, and social milestones—and when a code dies, social media keeps sharing it for weeks. This archive lists expired Mysterious Murderers codes so you stop wasting lobby time typing rewards that Roblox will reject with “invalid” or “expired” messages.
The game launched on 15 April 2026 under creator Winng3447 as a 12-player murder-mystery title with Murderer, Sheriff, and Innocent roles. It is not Murder Mystery 2; old MM2 compilations are a common source of false hope. For working rewards, use Active Codes instead. For menu help, see How to Redeem Codes.
Why expired codes still appear online
Short-form videos and repost accounts optimize for clicks, not accuracy. A code that worked on launch day may die after a patch while thumbnails still show ICE or FreeCoins. Developers rarely publish end dates, so wiki archives rely on community confirmation—when multiple players on fresh servers report failure, we move a string here.
Expired codes do not damage your account; the redeem box simply refuses them. The real cost is opportunity: minutes spent in Inventory could have been spent claiming OCEAN, SEASON4, or other active strings from our working list.
Confirmed expired codes
Do not expect these to return unless Granturismo explicitly re-enables an event. Typing them exactly will fail on current builds.
| Code | Known or suspected reward | Why it expired |
|---|---|---|
| ICE | Ice-themed weapon cosmetic | Launch/event window closed |
| PO1S | Poison or themed knife variant | Limited promo; leetspeak strings rotate quickly |
| IC3 | Ice-themed reward (alternate string) | Superseded by newer seasonal codes |
| R3D | Red-themed cosmetic | Short hype campaign |
| C0RRUPT | Corruption-themed skin | Event-limited |
| B4NN3D | Ban-hammer or joke themed item | Viral promo with short lifespan |
| 2023 | Legacy coin or cosmetic | Year stamp codes rarely stay live after calendar roll |
| E1ECTR0 | Electric-themed weapon | Replaced by newer energy skins like FUTURE |
| B4LCKNWH1TE | Black-and-white knife variant | Style drop expired after update cycle |
| SH4RKS33K3R | Shark-seeker themed reward | Seasonal beach tie-in ended |
| D4RTBR1NG3R | Dart/bringer themed cosmetic | Limited leetspeak promotion |
| M1DNIGH7 | Midnight-themed item | Time-limited release |
| FreeCoins | Coin bundle | Generic coin codes disable fast after economy tuning |
| UPDATEHYPE | Pre-update teaser reward | Tied to a specific patch trailer |
| PINK1 | Pink weapon cosmetic | First pink wave; see uncertain PINK2 on active list |
If you successfully redeem any code on this table on a current public server, treat that as a reactivation and notify friends—but default assumption is dead.
Uncertain overlap: PINK2 and FR33C4ROMA
PINK1 is archived here, while PINK2 remains on Active Codes with a “verify in-game” note. Color-themed promos often arrive in pairs; when PINK2 fails widely, it will move to this page.
FR33C4ROMA (Free Chroma) blurs the line between promo code and group milestone reward. The 50,000 member Free Chroma unlock for Granturismo Games may not require typing a string at all. If FR33C4ROMA fails, join the group and inspect Inventory before assuming chroma is unavailable.
What to use instead
Focus on codes players still confirm:
- Weapon cosmetics: OCEAN, GREEN, LAVA, BLU3CU4LASS, KNIFE, GUN, SEER, BEACH, WAVES, FUTURE
- Utility and currency: K3Y, SEASON4 (2500 Coins when live)
The Mysterious Murderers Codes Hub summarizes all three code pages. Cross-linking active and expired lists prevents duplicate work—bookmark both if you collect cosmetics across Murderer and Sheriff roles.
How expiry usually happens
Granturismo typically retires codes when:
- Season content ships — Season 4 brought SEASON4 coins while older hype strings stopped working.
- Economy patches land — FreeCoins-style bundles disappear after coin shop adjustments.
- Social campaigns end — Leetspeak joke codes (B4NN3D, C0RRUPT) were never meant to persist months.
- Cosmetic replacements release — Electric themes moved from E1ECTR0 toward newer laser items.
None of this is announced on a public timetable. Play for a week and you will feel the rhythm: new trailer, new code, old codes silently fail.
Avoiding fake codes from other games
Search algorithms mix Mysterious Murderers with Murder Mystery 2, Murder Mystery X, and unrelated Roblox horrors. Strings from those games will fail here 100% of the time. Read Mysterious Murderers vs Murder Mystery 2 if you are unsure which experience you installed.
Also verify you launched the correct experience via Play on Roblox—creator name Winng3447 / Granturismo Games on the official page.
Research habits that save time
- Test on a public server after joining from the official game page.
- Screenshot successful redeems with date visible for your friend group.
- When a code fails, check this page before trying random variants (extra spaces, wrong case).
- After major updates, skim Active Codes first—developers sometimes add replacements with similar themes (ice → waves → beach).
Inventory clutter and expired attempts
Failed redeems do not consume inventory slots, but repeated confusion leads players to misblame lag or role bugs. If Redeem greys out, see troubleshooting on How to Redeem Codes—the issue is often UI focus, not expiry.
Historical note for collectors
Even expired codes matter to completionists documenting Granturismo’s launch year. 2023 and UPDATEHYPE mark specific hype cycles; SH4RKS33K3R and BEACH-era themes show how beach and shark motifs rotated before BEACH and WAVES became active replacements. Keeping an archive helps new players understand why their favorite YouTuber’s list no longer matches reality.
When in doubt, play a round, enjoy the 12-player chaos, and redeem only from maintained lists. Expired pages age better than repost feeds—return after each patch so your inventory stays current without chasing ghosts.
Frequently Asked Questions
Quick answers about Mysterious Murderers, codes, and this wiki.
Does ICE still work in Mysterious Murderers?
No—ICE is confirmed expired. Use active alternatives like OCEAN or WAVES for themed weapon cosmetics.
Why do YouTubers still show FreeCoins?
Old videos stay up for views. FreeCoins was a limited coin promo and no longer redeems on current servers.
Can expired codes come back?
Rarely, during anniversary events. Do not rely on it—watch Granturismo announcements and our active list instead.
Is PINK1 the same as PINK2?
No. PINK1 is expired. PINK2 is a separate string—check the active page and verify in-game.
What happens if I type an expired code?
The game shows an invalid or expired message. Your account is fine—try a working code from the active list.
