MM2 KIDS Expired MM2 Codes Archive
Historical promo strings that no longer redeem — useful for spotting fakes and learning code history.
This archive lists expired Murder Mystery 2 codes so kids stop wasting rounds on dead strings. As of August 2026, the Active Codes list is empty. Everything below fails in the Inventory Enter Code box. Keep this page bookmarked next to How to Redeem and the parent Codes Hub.
Rewards listed are historical community records. Exact reward names can vary slightly across older write-ups; the important fact for families is status: expired.
Seasonal and recent expired codes
| Code | Historic reward notes | Status |
|---|---|---|
| SPRINGTIDE26 | Springtide Bloom Knife (seasonal) | Expired |
| NIK1LIS | Nikilis Knife | Expired |
| COMB4T2 | Combat II Knife | Expired |
| HW2017 | Pumpkin Pet (Halloween-era) | Expired |
SPRINGTIDE26 is the most common “is it still up?” search in 2026. It is not. Summer Event 2026 also did not revive it or ship a replacement string.
Classic creator and milestone codes
These older strings shaped MM2’s code culture. None work in August 2026:

Spelling variants appear because community lists disagree on exact capitalization. If any variant still fails, treat the code family as dead.
Why keep an expired archive?
- Stops scam loops — Fake “working code” videos reuse COMB4T2 and HW2017 thumbnails forever.
- Teaches leetspeak — Kids learn
4=A,0=O,3=Epatterns for future real codes. - Protects trades — Someone offering “unreleased code knives” after showing an expired string is waving a red flag; read Trading Safely.
- Supports history — Creator knives are part of MM2 collecting culture even when unobtainable from codes.
What expired does not mean
- It does not mean your already-redeemed knife disappears. Items stay in Inventory.
- It does not mean the knife has zero trade interest. Some old code knives still circulate — check Demand Explained and Godly Tier List for how collectors think (most code knives are not top Godlies, but nostalgia matters).
- It does not mean Nikilis will never release codes again. It only means these strings are finished.
How codes usually die
Codes expire when the developer ends the promotion, when a time window closes, or when a seasonal campaign ends. Players cannot “reactivate” them with VIP servers, alt accounts spam, or capitalization tricks. If Active Codes is empty, grind real rewards instead:
- Summer Event Shells and Summer Box ‘26
- How to Get Weapons box and coin paths
- Role skill from How to Play and Tips and Tricks
Parent tip: verify before you type
If a classmate or Discord user pastes a “new” code:
- Search it on this Expired archive.
- Check Active Codes.
- Only then open How to Redeem.
- Never install a helper app.
MM2 KIDS is built for kids and families — we would rather show an empty active table than recycle dead hope.

When a brand-new code finally appears, it will not be in this archive — it will headline Active Codes. Until then, treat every nostalgic string above as history, not homework.
Frequently Asked Questions
Quick answers to the most common questions.
Does SPRINGTIDE26 still work?
No. SPRINGTIDE26 is expired. As of August 2026 there are no active MM2 codes.
Will redeeming an expired code ban me?
No. Entering an expired code usually returns an error. It does not ban you, but spamming random strings wastes time.
If I redeemed COMB4T2 years ago, do I keep the knife?
Yes. Expired only means new redeems fail. Items already in your Inventory stay yours.
Why list codes that do not work?
So families can spot recycled fake “working code” posts and learn real MM2 code history.
Is NIK1LIS an active developer code?
No. NIK1LIS is an expired historic code tied to the Nikilis knife reward era.
