Each code (including powerupzbutworks, TB4LIFE, tdxiswinning, and the other listed codes) can be claimed once per account. Switching devices does not let the same account claim it again.
Use the copy button for powerupzbutworks or another listed code, then remove spaces before or after it. Capitalization matters: keep uppercase and lowercase letters exactly as listed. Check its status in the active list and code history. A rejection alone does not confirm that it has expired.
Tower Defense X (often abbreviated as TDX) is a highly polished, military-themed tower defense experience on Roblox, developed by the prominent content creator JOHN ROBLOX (under the Tower Defense X group). Departing from the usual anime or fantasy themes, TDX leans heavily into a sci-fi/military aesthetic where players deploy GDA (Global Defense Agency) troops, experimental mechs, and heavy artillery to fend off waves of zombies and massive alien entities like the Eradicator. The game stands out for its deep strategy, intense boss fights, and a branching upgrade system where players must choose between distinct top and bottom upgrade paths for their units. While the gameplay is highly rewarding, there is a significant grind to unlock the late-game towers, making promo codes an essential boost for skipping the early-game currency hurdles.
Codes are sourced from the game's community.
Unlike many simpler tower defense games, TDX features a branching upgrade system. When leveling up a unit mid-match, you must eventually choose between a top path (often focusing on raw damage or specific utility) and a bottom path (often focusing on fire rate, range, or crowd control). You cannot max out both paths on a single unit, adding a layer of strategic depth to your formations.
Some codes have a fixed expiry date; others are withdrawn without a published deadline. Check any expiry shown beside a code, and redeem it while it is still listed as active. The expired-code list keeps older codes for reference.
