Tower Defense X (TDX) is a military-themed tower defense game on Roblox developed by Top Down Games.

How to Redeem Codes in Tower Defense X
Redeeming codes in TDX is straightforward once you know where to look. The code input is accessed through the megaphone icon, which is easy to miss if you are not looking for it. Follow these steps:
- Open Roblox and launch Tower Defense X from the game page.
- Once you are in the game, look for the megaphone icon on the right side of your screen.
- Click the megaphone icon to open the code redemption panel. A text box will appear where you can enter your code.
- Paste your code into the text box exactly as shown. Codes are case-sensitive, and some include spaces or special characters that must match precisely.
- Press Enter on your keyboard to submit the code.
- If the code is valid, your rewards will be added to your account instantly. Check your inventory or currency balance to confirm the items arrived.
If a code does not work, double-check the spelling, capitalization, and any special characters. Pay special attention to codes with spaces like "cookies :3" since missing that space will cause the code to fail. If it still does not go through, the code has likely expired.
All Expired Tower Defense X Codes
The following codes have been deactivated and no longer work. We keep them listed here so you do not waste time entering codes that have already been removed from the system.
| Code | Status |
|---|---|
| SPOOKY2024 | Expired |
| SUMMER2024 | Expired |
| SPRING2024 | Expired |
| 100MVISITS | Expired |
| RELEASE | Expired |
The expired list reveals a clear pattern. Seasonal codes like SPOOKY2024, SUMMER2024, and SPRING2024 are tied to holiday events and get deactivated once the season ends. Milestone codes like 100MVISITS celebrate visit count achievements, and RELEASE was a one-time reward for early players. Expect new codes with future updates, seasonal events, and the next big milestone.
What Do Tower Defense X Codes Give You?
TDX codes reward a wider range of items than most Roblox tower defense games. Understanding what each reward does helps you make the most of your freebies.
Gold
Gold is the primary currency in Tower Defense X. You spend it on purchasing new towers, upgrading existing ones mid-match, and unlocking higher-tier units. Codes like tb4life (1,000 Gold) and XMAS24 (3,500 Gold) give you a meaningful head start. For new players, that early Gold injection means you can afford better towers from the beginning instead of grinding easy maps with starter units. Veterans can funnel the extra Gold into experimenting with different tower compositions on harder maps.
Crystals
Crystals are a premium resource used for special upgrades and rare content. The nightmare! code alone gives you 100 Crystals, which would otherwise take several play sessions to accumulate. Spend them on permanent upgrades rather than one-time consumables when possible.
Tactical Items
Several codes give you powerful consumable items that can turn the tide of a difficult match. Airstrikes deal massive area damage, Healing Fields restore base health, and the powerupzbutworks code is particularly valuable — it hands you A-10 Strafe Runs, an AC-130 Run, Stealth Sensors, Cash Crates, Health Crates, and Air Strikes all in one redemption. On nightmare difficulty, a single well-timed airstrike can save an otherwise lost run.
Drop Pods and Envelopes
Drop Pods contain randomized rewards with a chance at rare items — the goodbyexwm code provides them for free. Envelopes from lny2026 are special Lunar New Year items with themed rewards. Both are worth redeeming immediately since they cost you nothing.
Tower Placement and Strategy Tips for TDX
Codes give you resources, but knowing how to use them effectively is what separates players who clear nightmare maps from those who stall out on medium. Here are strategies to get more value out of every piece of Gold and every tactical item. For a full breakdown, check out our Tower Defense X free Robux guide.
Master chokepoint placement. Every TDX map has natural chokepoints where enemies are forced through narrow paths or tight turns. Placing your highest-damage towers at these points maximizes the time enemies spend in each tower's range. A single well-placed tower at a chokepoint often outperforms two or three towers scattered across the map. Before you spend any Gold upgrading, study the map layout and identify the spots where enemies slow down or cluster together.
Start with cost-efficient towers. When you are in the early waves of a match, resist the urge to immediately place your most expensive tower. Instead, use affordable starter towers like the Scout or Militant to handle the first few waves while you accumulate Gold. These low-cost towers deal enough damage against weak early enemies, and the Gold you save can be invested in placing a much stronger tower before the mid-game difficulty spike hits. Think of the first five waves as your economy phase.
Upgrade before you expand. A common mistake in TDX is placing too many towers at low upgrade levels instead of fully upgrading a smaller number of units. In almost every situation, a max-level tower outperforms two half-upgraded towers of the same type. Focus your Gold on pushing your core towers to their highest upgrade tier before branching out. This is especially true for towers with powerful final upgrades that unlock new abilities or dramatically increase their fire rate.
Save tactical items for emergency moments. Those free Airstrikes, Healing Fields, and Strafe Runs from codes are not meant for easy waves. Hold onto them for the late-game surges when boss enemies or massive waves threaten to overwhelm your defenses. A well-timed Healing Field during the final wave of a nightmare map can be the difference between a victory and a restart. Think of tactical items as insurance, not regular tools.
Balance single-target and area-of-effect towers. Some waves send a few high-health enemies, while others flood you with dozens of weak ones. If your entire setup is single-target towers, you will struggle against swarm waves. If it is all splash damage, bosses will walk right through. Build a balanced composition with AoE towers near chokepoints and single-target damage dealers focused on tanky enemies.
Where Do New Tower Defense X Codes Come From?
Staying ahead of code releases means knowing where the developers announce them. Here are the main sources for new TDX codes:
Official Discord server: The TDX Discord is the fastest place to find new codes. The developers post them in announcement channels, and community members share them within minutes.
X/Twitter and social media: Top Down Games posts codes alongside update announcements on social media. Discord typically gets codes a few minutes earlier, but social media is a solid backup.
Game updates and events: Major patches, seasonal events, and holiday celebrations almost always come with at least one new code. The expired list shows this clearly — XMAS24 for Christmas, SPOOKY2024 for Halloween, and so on.
Visit milestones: The 100MVISITS code was released when TDX hit 100 million visits. With the game at around 383 million now, the next milestone will almost certainly bring a new code.
We monitor all of these sources and update this page as soon as new codes are confirmed.

Frequently Asked Questions
Launch Tower Defense X on Roblox and wait until you are in the game. Click the megaphone icon on the right side of the screen to open the code redemption panel. Paste your code into the text box and press Enter. If the code is valid, your rewards will appear in your account immediately.
The most common reasons are expired codes, already-redeemed codes, or typos. TDX codes are case-sensitive, and some contain spaces or special characters that need to match exactly. Copy and paste directly from this page rather than typing codes manually. If a correctly entered code still fails, it has been deactivated by the developers.
New codes typically arrive alongside major game updates, holiday events, and visit milestones. The developers at Top Down Games do not follow a fixed schedule, but codes tend to appear every few weeks. Following the official Discord server is the fastest way to catch them when they drop.
No. Each code can only be redeemed once per Roblox account. If you try to use a code you have already claimed, the game will reject it. There is no way to redeem the same code on the same account twice.
Yes. Most TDX codes have a limited availability window. Event codes like XMAS24 and SPOOKY2024 expire when the event ends, and update codes may be deactivated when the next patch goes live. The developers can remove codes at any time without prior notice, so redeem them as soon as you see them.
TDX codes give a variety of rewards including Gold (the main currency for buying and upgrading towers), Crystals (a premium resource for rare upgrades), Drop Pods (randomized loot containers), and tactical consumables like Airstrikes, Healing Fields, Stealth Sensors, and Strafe Runs. The powerupzbutworks code alone gives you six different types of items.
