Trench Decay Codes
Community-reported promo codes for medals, Enlisted crates, and cosmetic rewards — redeem before they expire.
TRENCH: DECAY is an early-access WW1 squad PvE FPS on Roblox by studio rook., and promo codes are one of the fastest ways to stock medals and Enlisted crates without grinding every deployment. This hub tracks every code players are reporting as working during beta, explains what each reward does, and links to step-by-step redemption help.
Codes are community-reported and can stop working after balance patches or milestone events. Treat the list below as a living checklist: redeem everything you have not claimed yet, then bookmark this page and check back after major updates.
August 2026 community checks
As of August 2026, Discord threads and Roblox experience comments still report the table below as redeemable after joining studio rook. — but beta milestones rotate fast. Community spot-checks in late July and early August confirmed most milestone strings still return success popups on fresh servers. If a code fails despite correct capitalization, assume it expired rather than blaming your account.
After any patch flagged on the Updates Hub, rerun every unclaimed code. studio rook. often ships secret or unannounced hotfixes alongside visit milestones; players who only check social media miss short-lived promos like 5KMEMBERSPEAK! that community trackers label as new.
Requirements before you redeem
Every working Trench Decay code currently requires you to join the studio rook. Roblox group while logged into the same account you use in-game. Some players also report needing to favorite the experience on Roblox before the Supply Codes button accepts input. If redemption fails, fix group membership first — see the full walkthrough on the how to redeem codes page.
Active codes (community-reported)
Copy codes exactly — capitalization matters. Rewards below come from community reports and official milestone posts; studio rook. may change values without notice.

If a code returns an error despite correct typing, assume it expired. No publicly confirmed expired list exists yet, but beta milestones rotate quickly.
What you actually get
Medals are the premium currency used in the depot for spins, crate purchases, and selected cosmetics. Enlisted crates roll random rewards by type: Cosmetic (uniforms and flair), Firearms (primary weapons), and Melee (trench clubs, shovels, and similar). Codes stack with in-run loot — they do not replace squad play on the Live War Map, but they shorten the early grind.
For a full breakdown of each crate type, medal sinks, and how code rewards compare to mission payouts, read the code rewards guide.
Quick redemption steps
- Join studio rook. on Roblox with the account you play on.
- Launch TRENCH: DECAY and load into the hub.
- Click Supply Codes on the right side of the screen.

Stuck on a failed redeem? The how to redeem codes guide covers group delays, mobile keyboard issues, and the difference between “Invalid code” and “Requirements not met.”
When to check back
studio rook. ships frequent beta patches — visit milestones often tie to new codes (visit counts, front-page features, major updates). After each patch notes post, run through the table above and cross-check Discord or the experience description for fresh strings.
New to the game itself? Pair code redemption with the Getting Started guide so your first squad deployment is not wasted loot. Progress saves during beta unless studio rook. announces a wipe.
Frequently Asked Questions
Quick answers to the most common questions.
Do Trench Decay codes expire?
Yes — codes are tied to beta milestones and can stop working after updates. Redeem community-reported codes as soon as you join the studio rook. group; this page tracks what players still report as working in August 2026.
Why does my code say requirements not met?
You almost certainly need to join the studio rook. Roblox group on the same account you use in-game. Favorite the experience if redemption still fails, then rejoin a fresh server.
Where is the Supply Codes button?
After loading into TRENCH: DECAY, look at the right edge of the screen for Supply Codes. Tap it, type the code exactly as written, and press Redeem.
Can I redeem codes on mobile?
Yes. Join the group in the Roblox app first, launch the game, open Supply Codes, and paste carefully — mobile autocorrect often breaks capitalization-sensitive codes.
What is the best code for new players?
Community reports rank 1MVISITS and 1KCCUREWARD among the largest bundles — 800+ medals plus multiple crates. Redeem every code you can; rewards stack.
Is 5KMEMBERSPEAK! still working?
Community trackers flagged it as new in mid-2026. Join studio rook., redeem on a fresh server, and report failures on Discord — milestone codes can vanish without announcement.
