You're probably tired of clicking on those sketchy sites that promise "10,000 Gold" only to find out the codes expired back when the game first hit Roblox. It's frustrating. Honestly, hunting for tower defense x beta codes feels like a game of whack-a-mole because Paradoxum Games—the developers led by the well-known Tower Battles creator, Planet_Milo—doesn't just hand them out like candy.
TDX is different. It’s gritty.
Most tower defense games on the platform are bright, colorful, and frankly, a bit too easy. Tower Defense X (TDX) leans into a more "military sim" aesthetic that requires actual brainpower to beat. Because the difficulty curve is so steep, getting a boost from a code can be the difference between clearing a wave and watching your base health hit zero while you're still trying to afford a basic Ranger.

Why the Beta Codes Are So Hard to Pin Down
Let's be real about the "Beta" tag. TDX spent a massive amount of time in private testing before its public launch, and many of the codes floating around the internet today are artifacts from that era. They don't work anymore. If you see a code like "beta" or "release," chances are it's been deactivated for months.
The game’s economy is tightly balanced. Paradoxum Games uses codes primarily to celebrate major milestones, like hitting a certain number of likes on the Roblox page or reaching a specific player count. They aren't just random strings of text; they are rewards for the community’s growth.
Current Active Codes and What You Get
As of early 2026, the pool of working codes is smaller than most people expect. You aren't going to find 50 active ones. Usually, there are only two or three live at any given time.
johnroblox — This is the classic. It’s usually active and gives you a bit of XP and Gold to get started. John Roblox is a massive part of the game's identity, and this code is a nod to his influence on the project.
atlonglast — This one was released to celebrate the massive update that overhauled the UI and added new towers. It provides a decent chunk of Gold, which is essential because, let's face it, the starting towers in TDX are "okay," but you need the heavy hitters if you want to survive Intermediate or Expert modes.
60MVISITS (or similar milestone variations) — These change. You have to keep an eye on the official TDX Discord or Planet_Milo's Twitter (X) account. When the game hits a big number, a code usually follows within 24 hours. If you try a code and it says "Expired," it’s not a bug. The devs are notoriously quick about turning these off once the celebration period ends.
The Problem With Fake Generators
Stop. Don't do it.
If a website asks you to "verify you're human" by downloading an app or taking a survey to unlock tower defense x beta codes, you are being scammed. There is no such thing as a code generator for Roblox. Codes are hard-coded into the game’s script by the developers. No third-party tool can inject a new code into the game's database.
I’ve seen players lose their accounts because they entered their Roblox password into "code leak" sites. It’s not worth it for 500 Gold. Just play the game. Even a losing round gives you some XP and Gold, and in TDX, the grind is actually part of the fun because you're learning the tower placements.
How to Redeem Your Rewards
It’s not hidden, but if you’re new, the UI can be a bit overwhelming.
Look at the right side of your screen when you’re in the main lobby. You’ll see a megaphone icon or a button labeled "Codes." Click it. A text box pops up. Copy and paste the code exactly—TDX codes are usually case-sensitive. If the code is JOHNROBLOX and you type johnroblox, it might not work. Hit enter, and if you see green text, you’re rich (relatively speaking).
Making the Most of Your Gold
Once you've used your tower defense x beta codes, don't just blow the Gold on the first thing you see. The meta in TDX shifts constantly.
Initially, you’ll want to focus on towers that have good "Gold-to-DPS" ratios. The Shotgunner is a fan favorite for a reason; it’s cheap and punches way above its weight class in the early game. If you’ve managed to save up a few thousand Gold from codes and a few matches, look into the Farm. Like any good tower defense game, your economy is everything. If you don't place Farms early, you won't be able to afford the Railgunner or the X-01 Power Armor later on.
The Strategy Behind the Beta
The "Beta" in the title is more than just a label. It means the game is still being balanced.
Sometimes a tower you bought with code-provided Gold might get "nerfed" (weakened) in a Tuesday update. Don't get salty. This is part of the process. The developers are trying to make sure the game isn't just "spam one tower to win." They want you to use a mix of air defense, ground troops, and support units like the Medic.
If you're struggling even after using codes, try joining the "Endless" mode with higher-level players. You'll gain XP much faster, which unlocks the ability to buy even better towers. The community in the lobby is usually pretty helpful, provided you aren't "leaking" (letting enemies past your defense) constantly.
Where to Find New Codes First
If you want to be the first to get the newest tower defense x beta codes, you need to be where the devs are.
- The Official Discord: This is the gold mine. They have a specific channel for announcements. When a code drops, the "ping" will go off, and you'll know instantly.
- Planet_Milo on Twitter: He’s the lead. Sometimes he drops "hidden" codes in screenshots of upcoming towers. You have to look closely at the background.
- The TDX Wiki: It’s maintained by players who are obsessed with the game. They are usually very good about marking which codes are "Active" and which are "Expired."
Actionable Next Steps
Don't let your Gold sit idle. The best way to progress is to use those rewards to bridge the gap between "Beginner" and "Intermediate" maps.
- Check the Discord daily: Join the Paradoxum Games server and mute everything except the #announcements channel.
- Invest in the Farm: Use your code Gold to buy or upgrade your income-generating towers first.
- Watch the Meta: Before buying an expensive tower, watch a recent YouTube video from 2026 to see if it’s still viable or if it’s been nerfed into the ground.
- Focus on XP: Codes give you a head start, but your level restricts what you can buy. Use the Gold from codes to buy towers that help you survive longer, which in turn grants you more XP per round.
Playing TDX is a marathon, not a sprint. The codes are just the fuel to get you through the first few miles.
