TDS Codes (October 2026)

Codes checked: 1 October 2026 · Game last updated by the developer: 25 September 2026

Looking for TDS codes? Every code that still works in Tower Defense Simulator, the co-op Roblox game where you place towers to hold back waves of zombies, is listed below with its reward, followed by the codes that have expired.

Current codes unlock tower skins rather than Coins or Gems, and a skin code only pays out if you already own the tower it belongs to. New codes are rare and tied to milestones and holidays, so claim them while they last.

All Working TDS Codes

• 2MILLION: Mercenary skin for Pursuit
• 1MILCOMMUNITY: Community skin for Shotgunner

You need to own Pursuit to claim the Mercenary skin and Shotgunner to claim the Community skin. Buy the tower first, then redeem.

How to Redeem TDS Codes

1. Launch Tower Defense Simulator and wait in the main lobby.
2. Click the codes button in the top-right corner of the screen, marked with the letters ABX.
3. Type a code into the Enter Code Here box.
4. Click Redeem, then open the tower’s skins to equip your reward.

Codes can only be redeemed from the lobby, not in the middle of a match.

What TDS Code Skins Do

Tower skins change how a tower looks, not how it performs, so the current codes are purely cosmetic. Both belong to the Traditional Code Skins series, which collects the skins handed out through developer codes, and most earlier skins in that series can no longer be claimed.

Older codes paid out Coins, Gems, EXP, crates, nametags, emotes and even whole towers, and some had limited stock or a 24 to 48 hour window. Separately, joining the Paradoxum Games group on Roblox gives you an extra $100 of starting cash in matches.

What Is Tower Defense Simulator?

Tower Defense Simulator is a co-op tower defense game. You place units to hold off hordes of zombies, team up with friends against tougher bosses, and unlock new towers with the Coins, EXP and Gems you earn after each match. Survival, Hardcore and PvP modes sit on top, and it runs on PC, mobile and consoles.

It is made by Paradoxum Games, the studio run by BelowNatural, and officially launched on 14 June 2019. As of 1 October 2026 it had more than 4.9 billion visits and 3.5 million favorites.

Where to Find New TDS Codes

New codes are announced on Paradoxum Games on X and in the official Discord, and now and then in the game’s Roblox description. They usually mark community milestones, such as likes, visits or Discord members, and holidays: Christmas brought a code every year from 2021 to 2025.

Frequently Asked Questions

Why won’t my TDS skin code redeem?

Skin codes only pay out if you already own the matching tower, so buy Pursuit or Shotgunner first. Then check the spelling and redeem from the lobby; if it still fails, the code has expired.

What does TDS stand for?

Tower Defense Simulator, the zombie tower defense game made by Paradoxum Games.

Do Tower Defense Simulator codes give Gems?

Not at the moment. The working codes give tower skins, while older codes gave Coins, Gems and crates.

Do TDS merch codes still work?

No. Codes that came with plushies and apparel stopped being issued in May 2025, and those items now come from the in-game Merch Shop.
