Tower Defense Simulator codes unlock tower skins and, in past promotions, crates, coins, gems and experience. The game comes from Paradoxum Games, the Roblox studio behind Alter Ego, and it is one of the platform's most established tower defense titles: nearly 5 billion visits since its June 2019 launch, around 3.5 million favorites, and roughly 17,000 players online at any given moment. Codes arrive rarely here and are usually tied to milestones such as 1 million community members or 2 million likes. We check every code in the lobby each day and move anything that fails into the expired list below.

About Tower Defense Simulator
Tower Defense Simulator is a cooperative tower defense game on Roblox in which a team of players places towers along a fixed path to stop waves of zombies from reaching their base. Each tower has a cash cost, a placement limit and a set of upgrades bought with the money earned from kills, so a match is a constant trade between spreading defenses early and saving for high-level upgrades before the boss waves. Towers are unlocked with coins between matches, and the roster runs from the starter Scout up to intermediate units such as the Pulse Trooper and endgame towers earned through Hardcore mode.
The game was published by Paradoxum Games in June 2019 and has since passed 4.9 billion visits, 3.4 million favorites and 6 million group members. Modes include the standard difficulty ladder, Hardcore, a Story Mode with cutscenes, and rotating seasonal events, each with its own crates, skins and emotes. Progression is driven by coins, gems and a battle pass, and the store sells skins on a rotating schedule.
What is new right now
Version 2.10.0 added the Pulse Trooper, a 3,250-coin ground tower that fires a piercing pulse in a full 360-degree arc and unlocks a map-wide Sweeper ability at Level 4. It has a placement limit of seven per player and gains lead detection from Level 2. The update before it, 2.9.0, closed out the summer skin rotation with a final wave of skins and a Labor Day sale of up to 30 percent off, according to the official Roblox page.
Codes matter here because Paradoxum rarely gives towers or skins away outside of them. Both codes that work today are milestone rewards, one for a 1 million community milestone and one for 2 million likes, and each grants a skin you cannot buy in the store. Older codes have handed out crates, coins, gems, experience and even whole towers such as the Hunter, so it is worth redeeming anything new the day it appears, since many codes have carried stock limits or short expiry windows.
Where new codes come from
Codes are announced by Paradoxum Games on the Tower Defense Simulator Roblox page, on the studio's X account and in the official TDS Discord server. The Codes page on the Tower Defense Simulator Wiki keeps a dated log of every code and its expiry.

Tower Defense Simulator codes FAQ
Why does 2MILLION or 1MILCOMMUNITY not give me anything?
Both codes are tower skins. 2MILLION gives the Mercenary skin for Pursuit and 1MILCOMMUNITY gives the Community skin for Shotgunner, so you need to own that tower before the code will redeem. Buy the tower in the store, then enter the code again.
Where is the code box in Tower Defense Simulator?
It is in the top-right corner of the lobby screen, shown as a small icon marked ABX. It is only available in the lobby, not during a match.
Are Tower Defense Simulator codes case-sensitive?
Yes. Codes such as NOTESLA? and TDS5YEARS! have included punctuation, and lowercase codes like beachglad2022 have been used, so copy each code exactly as it appears.
How often does Paradoxum Games release new codes?
Rarely. Codes typically mark milestones such as visit counts, like counts or Christmas, and several past codes had limited stock or expired within 24 to 48 hours. Both current codes date from June 2026.
Do the old plush merchandise codes still work?
No. Since May 2025 the plush skins are no longer given out as codes; they are obtained through the in-game Merch Shop instead.
