WEAPON DUELS September 2026 Update
Monarch Bundle has ended, Season II Sea Serpent continues through 23 Sep, Season 4 speculation builds, and four active codes still redeemable.
September 2026 — What Shipped and What Is Coming
September 2026 brought several material changes to WEAPON DUELS by Twin Comets. The Monarch Bundle window closed on 5 September 2026, the game crossed 25.4 million visits, and the community’s attention has shifted toward Season 4 predictions while Season II Sea Serpent runs its final weeks. This page documents every verified September development so you know exactly what is live right now.
If you returned after a short break, start here. The short version: the Monarch Bundle is gone, four codes remain active, and Sea Serpent season pass is your main time-limited earn before the season closes on 23 September 2026.
What ended: Monarch Bundle (5 September 2026)
The Sun & Moon / Monarch Bundle expired on 5 September 2026 as scheduled. The timed shop SKU — which included a unique finisher and a chance at a prismatic variant — is no longer available in the store. Prismatic Monarch items that entered circulation during the window are now tradeable at whatever the community values them. If you missed it, the cosmetic is now purely a secondary market item; do not pay inflated Discord prices for something that was a limited-time purchase.
What is still live: Season II Sea Serpent (ends 23 September 2026)
The Season II Sea Serpent battle pass continues through 23 September 2026. Free track items and any purchased premium tiers are still claimable. If you have not finished the track, these final weeks are the highest-value play window — tier rewards include sea-serpent weapon skins that remain tradeable after the season closes.
After 23 September 2026, Twin Comets will likely begin the next seasonal cycle. Watch the Season 4 roadmap for speculation and the Changelog for verified dates the moment they appear.
Active codes right now (September 2026)
Four codes remain active and redeemable on place 82983707799188:
| Code | Reward | Status |
|---|---|---|
| DANGO | Dango cosmetic + Dango Gun | Active — printed on official Roblox description |
| Rad | Mythic Outfit (one copy) | Active — reported 30 Aug 2026 |
| PONY | Purple Pony weapon | Active — still listed on official description |
| Pew Pew | Pew Pew Gun | Active — tracked by code-update channels |
If any code fails, rejoin a fresh server before assuming expiration. Code cooldowns are tied to server sessions, not account locks. Full redemption walk-through with screenshots is on the Codes page.
Season II Sea Serpent: final three weeks
With the season closing on 23 September 2026, these three actions matter most:
- Check your battle pass tier. If you are within 5–10 tiers of a weapon skin you want, grind daily quests to close the gap.
- Hold Sea Serpent cosmetics for trading. Supply is still entering the market through late-season players, but demand from collectors peaks in the two weeks after the season closes.
- Redeem codes before the season ends. New accounts created during the Sea Serpent window may be more likely to receive milestone codes.
Season 4: where we stand
The Season 4 roadmap tracks publicly verifiable signals. No Twin Comets announcement had dropped at time of writing, but the community is watching for:
- A new themed battle pass following Sea Serpent
- A new map (a smaller arena has been discussed since Aztec Part II Runic shipped)
- Console support (listed as coming soon — see the Console roadmap)
Twin Comets has not confirmed any of these. The moment an official announcement lands, we will publish a dedicated Season 4 patch page.
Community health: September 2026
The game reached 25.4 million visits and approximately 605,000 favorites as of August 2026. The Twin Comets Discord remains the primary community hub; there is still no official Trello.
What to do right now
- Redeem DANGO, Rad, PONY, and Pew Pew if you have not. Steps are on the Codes page.
- Finish the Sea Serpent battle pass if you are close to a reward you want — only three weeks remain.
- Save Stars rather than spending on rotating shop items. A new season typically ships a fresh battle pass.
- Check the Changelog after every play session for hotfixes.
- Read Season 4 roadmap so you are not caught off-guard when the announcement drops.

Frequently Asked Questions
Quick answers to the most common questions.
Did the Monarch Bundle come back after 5 September 2026?
No confirmed return at time of writing. The 5 September expiration date was listed in public event data; treat it as a one-time window. Prismatic Monarch items from the window are now tradeable on the secondary market.
How many active codes does WEAPON DUELS have in September 2026?
Four confirmed active strings: DANGO, Rad, PONY, and Pew Pew. STARS30 remains unverified — try once on a fresh server but do not spam the box.
When does Season II Sea Serpent end?
23 September 2026 per public battle pass listings. After that date, the season track locks and premium tiers become unavailable for purchase.
Has Season 4 been announced?
No official announcement at time of writing. The Season 4 roadmap page tracks speculation from community signals. Check the Changelog and Discord announcements the moment a real update lands.
What should I do with my Stars before Season 4?
Hold them. New battle passes typically launch alongside new seasons and represent the highest-value Stars expenditure. Redeem all active codes first to reduce what you need to grind.
Where do I find new codes after September?
The official Discord at discord.gg/weapon-duels is the primary channel. Codes also appear in the Roblox game description and in-game banners. No official Trello exists.
