Untitled Defense Codes: 12 Working Codes (October 2026)
Untitled Defense is running a big batch of live codes right now — twelve of them, all paying out Gems and Trait Rerolls. Redeem every one and you pocket 22,000 Gems and 1,200 Trait Rerolls for free. Redemption happens entirely in game: walk to the Codes Area near the Spawn Point, step inside, and the Codes Tab opens.
All 12 working Untitled Defense codes
Every code below was listed as active on both Pro Game Guides and Destructoid, each with the page updated on October 4, 2026. If a code is not on this list, it is not confirmed working right now.
Sources checked: Pro Game Guides — Untitled Defense Codes and Destructoid — Untitled Defense codes. Both carry the same twelve codes and the same payouts.

Case matters. 100KVISITS is typed in all upper case and 200KVisits in mixed case, and they are two different codes. thankyouguys, sorryforfate and luvfromcashmere are all lower case with no spaces. A single wrong letter is the most common reason a code fails.

100KVISITSis the highest-value code in the list at 5,000 Gems and 150 Trait Rerolls. If you only have time for one, do that one first.
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 full batch is worth 22,000 Gems and 1,200 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 22,000 of them. That is enough to make a real dent in a banner, so do not trickle them 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.
Five of the live codes are named after server milestones: 1KCCU, 400CCU, 600Members, 100KVISITS, 200KVisits. Earlier milestone codes have already been retired — 100CCU, 300CCU, 1KMEMBERS, 25KVisits, 40KVISITS, 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 thirteen codes were listed as inactive. Available sources only show "Free Rewards" for them now, so the payout amounts are no longer published and 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 12 codes working right now?
All twelve were listed as active on two separate Roblox code trackers, both updated on October 4, 2026, and the amounts they pay match on both. Neither site confirms redemption by logging into a server, so if one fails for you it was likely retired between their update and your attempt. Skip it and move to the next one.
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 BATTLEPASS and battlepass 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 400CCU 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. Codes also tend to appear alongside updates, so our UPD2 page is worth a look after any patch.
