Untitled Defense Codes: 5 Working Codes (October 2026)
Untitled Defense has five live codes right now. The two that still carry a published payout hand over 1,000 Gems and 300 Trait Rerolls between them; the other three are listed as working without an itemized reward. Redemption happens entirely in game: walk to the Codes Area near the Spawn Point, step inside, and the Codes Tab opens.
All 5 working Untitled Defense codes
Every code below appears on a tracker page that was still being updated in the second half of October 2026. The long list of visit and member milestones that older pages carried has been retired; those codes now sit in the expired section further down.
Sources checked: the official Roblox experience page, its community group, and two Roblox code trackers updated in October 2026. The official description lists no codes, so tracker pages are the only record of these.

Case matters. newrebalances is all lower case, while 2KCCU and 10KMembers mix capitals and digits. Bleach is a single capitalised word. A single wrong letter is the most common reason a code fails.

How to redeem a code in Untitled Defense
There is no website and no external redemption portal. Everything happens inside a Roblox server:
- Launch Untitled Defense on Roblox and load into a server.
- Walk to the Codes Area near the Spawn Point — look for the marked code zone in the lobby.
- Step inside it and the Codes Tab pops up.
- Paste or type the code into the box, then press Redeem.
- Your Gems and Trait Rerolls land in your account straight away.
Run the first redeem in a regular public server. A reward pop-up you have not seen before is a good sign the code registered on your account rather than the server.
Spend the payouts in this order
The published payouts add up to 1,000 Gems and 300 Trait Rerolls, and those two currencies do very different jobs. Gems are what you summon units with. Trait Rerolls are what you improve traits on units you already own. Neither job works without the other currency holding it up, so the order matters.
Spend Trait Rerolls first, in batches. Rerolls are the scarcer resource relative to what they do, and they are the part that gets wasted fastest. Open the reroll menu, decide which single unit is worth chasing, and dump a large number of rerolls into that one target rather than tapping reroll once and re-checking. Players in this game's community have reported burning 2,000-plus rerolls for one desired trait roll — drip-feeding the button just loses rerolls faster.
Hold Gems for a summon, not for rerolls. Gems are the currency you spend at the summon screen, and this batch alone hands you roughly 1,000 of them. That is a small top-up rather than a banner, so do not trickle it away unit by unit while you are still undecided. If you are not sure who to pull, our tier list page covers how to decide without wasting a banner.
Three of the live codes are named after server milestones: 1KCCU, 2KCCU and 10KMembers. Earlier milestone codes have already been retired — 100CCU, 300CCU, 1KMEMBERS, 25KVisits, 40KVISITS, 100KVISITS and THANKSFOR10KVISITS all sit in the expired list. New milestones mean new codes, so check back rather than treating this list as permanent.
Codes that have already expired
These twenty-five codes have been retired. Current tracker pages no longer list any of them as active, so there is no point spending a redeem slot on them.

Searching for Untitled Defense codes surfaces pages mixing in codes from Untitled Tower Defense Game, a much older and completely different Roblox game, and from Universal Tower Defense X and Z. Those games have their own currencies and their own Trait Reroll systems. A code that works in UTDX will not pay out here.
FAQ
Are all 5 codes working right now?
Four of the five sit in the active block of both tracker pages this list was checked against. 1KCCU is the exception: Pocket Tactics still lists it as working after its October 19, 2026 check, while Destructoid has moved it to its expired list. It is kept here because 100 Trait Rerolls is worth a try, but if it fails for you treat it as retired and move on.
Why does my code say it is invalid?
Three causes cover nearly every failure: wrong letter case, a code that has already expired (see the list above), or a code copied from a different Roblox tower defense game. Codes here are not case-insensitive, so Bleach and bleach are not the same code.
Does redeeming take Gems or Trait Rerolls away from me?
No. Redeeming is a one-time grant. Codes add to your balance, they do not consume it. The only cost is the walk to the Codes Area.
Do the milestone codes expire?
They do. 1KCCU and 2KCCU are live while 100CCU and 300CCU are dead, which means a code can pay out once and then be switched off after its milestone passes. Redeem milestone codes the day you see them instead of saving them for later.
Where else should I check for new codes?
The official server is the fastest channel — see our Discord page for the discord.gg/untitleddefense invite and what to watch there. The Roblox group also posts milestone announcements. Codes also tend to appear alongside updates, so our UPD2 page is worth a look after any patch.
