TB II Tower Defense X BETA Working TDX Codes

Promo codes are one of the fastest ways to stockpile Gold, XP, cosmetic tags, and combat consumables in Tower Defense X (TDX). This hub lists codes that community sources still report as redeemable in October 2026, explains exactly how to redeem them, and shows how those rewards feed into early progression, co-op Expert clears, and the ongoing TB II Collab event.

Codes expire without warning when JOHN ROBLOX or the Tower Defense X group rotates them. Treat every entry below as time-sensitive: redeem as soon as you join, then spend Gold on towers you actually need instead of hoarding forever. If a code fails, check casing first — TDX codes are case-sensitive — then assume it expired and move on.

New players should redeem everything here, then jump into the Guides hub (especially Getting Started) so the free Gold and power-ups actually land on a coherent loadout. Veterans can skim the active list, claim what is left, and route rewards into farming or Expert practice covered on the Tier List and Players hubs.

Active codes (October 2026)

Rewards below are what multiple code trackers report. Exact payouts can differ by account or patch, and some codes may already be dead by the time you read this. Always paste carefully.

Code	Reported reward
tdxiswinning	TDX Name Tag and/or Gold (trackers disagree on the exact Gold amount; many list a Name Tag)
TB4LIFE	Gold — sources vary from about 1,000 to 10,000; try this exact casing first
johnrobloxforever	500 Gold + 1,000 XP
powerupzbutworks	Free power-up pack (commonly listed as A-10 Strafe, Cash Crates, Health Crates, Air Strikes, Stealth Sensors, AC-130, and similar consumables)

Notes on casing and payouts

• TB4LIFE vs tb4life: Some older lists used lowercase. Start with TB4LIFE. If that fails, try the lowercase variant once before marking it expired.
• tdxiswinning: Often tied to a TDX Name Tag; some roundups also mention Gold. Redeem for the tag and any Gold that comes with it.
• johnrobloxforever: One of the most consistent entries — 500 Gold and 1,000 XP across recent lists.
• powerupzbutworks: The big consumable dump. Use the crates and airstrikes on hard waves or co-op pushes instead of burning them on Easy farming you already clear cleanly.

If a code returns an error after a clean paste, it is almost certainly expired or already redeemed on that account. Do not spam-redeem; it will not force a payout.

How to redeem codes in Tower Defense X

You redeem inside the experience, not through Roblox chat or the website.

1. Launch Tower Defense X from Roblox (place ID 9503261072, currently branded around the TB II Collab / Raze the Void era).
2. Open the codes UI — either the megaphone control on the side of the lobby/HUD, or the three-dots menu (often top-left) → Codes.
3. Paste one code into the ENTER CODE field. Codes are case-sensitive; copy-paste beats typing.
4. Press Redeem (or Enter, depending on the UI build) and wait for the success or failure toast.
5. Repeat for each remaining code. Check inventory / currency counters so you know Gold, XP, and power-ups actually landed.

No special level gate is required for normal promo codes. You do need a working Roblox account and a server that still has the Codes menu enabled. If the menu is missing after a major update, rejoin or wait for a hotfix — do not assume codes moved to Discord chat.

What to spend code rewards on

Gold is the long-term meta currency for unlocking and progressing towers outside a match. Cash is the in-match economy for placing and upgrading during a wave. Codes that grant Gold help your account power; codes that grant crates, airstrikes, and sensors help a single hard clear.

Practical spend order for most accounts:

1. Unlock or shore up a reliable early tower line you will actually place (see Tier List and Players for current picks).
2. Keep a buffer of Gold for Battle Pass / event sinks if an active pass is running — Tokens and event shops rotate with updates.
3. Dump power-up packs into Expert or collab content where a failed wave costs more time than Easy autofarms.
4. Use the XP bump from johnrobloxforever as a small account push, then keep leveling through normal clears and the Updates event track.

Crystals, Tokens, and other currencies usually come from gameplay, shops, or Battle Pass tracks rather than these four codes. Treat code Gold as acceleration, not a full economy replacement.

Expired and unreliable codes

Treat the strings below as expired (or unreliable across trackers). Paste them only if you enjoy watching failure toasts — they are listed so you can stop chasing old screenshots.

Expired / unreliable code	Notes
nightmare!	Old difficulty meme drop — dead
ez	Short meme code — expired
lny2026	Lunar New Year 2026 seasonal — expired
TDX25	Anniversary-style string — expired
cookies :3	Meme / seasonal — expired
America250	Patriotic seasonal — expired
FREEDOM	Same window as America250-style promos — expired
XMAS24	Christmas 2024 — long expired
goodbyexwm	One-off farewell string — expired
GiftFromXonaeAndLora	Creator gift drop — expired
Numbered johnroblox* variants	One-off JOHN ROBLOX numbered drops (any trailing digits / suffixes) — treat as dead
atrazine	Old meme / community string — expired
PowerUpz	Predecessor to powerupzbutworks; this exact casing is expired
Cost efficiency	Phrase-style promo — expired
FREEMLG	Old freebie string — expired

TB II launch note: The Raze the Void collab that went live on 26 September 2026 did not drop a fresh public code wave with the update. Keep redeeming the four actives above; do not expect a hidden TBII string that trackers somehow missed.

TB4LIFE caveat: Reward reports still disagree — about 1,000 Gold on some lists versus about 10,000 Gold on others. Redeem the exact TB4LIFE casing once, take whatever lands, and move on. Do not re-paste hoping for the higher number.

Older roundups still float more Christmas leftovers and random Discord leaks. This hub stays focused on the short active set so you are not pasting twenty dead strings. When Discord or the official X/Twitter account announces a new drop, we will refresh this page.

Never buy “private code lists” from random sellers. Official promos are free. If someone DMs you a “working code pack” behind a paywall, treat it as a scam.

Codes, co-op, and the TB II Collab

TDX is built for online co-op with land, air, and sea placement, dual upgrade paths, and towers that can take damage. Free Gold and consumables matter more when your squad is pushing Expert or collab maps where a single leak ends the run. Redeem before you queue so everyone starts with the same power-up floor.

During the TB II Collab (Raze the Void) window that began in late September 2026, expect more limited-time rewards from events than from evergreen codes. Still redeem the four actives above — they stack with event progress instead of replacing it. Pair this page with Updates for patch notes and Guides for farming and boss routes.

Staying current

• Check this Codes Hub after major updates or livestreams.
• Follow official channels listed on Official Links (Discord, X/Twitter, Roblox group).
• After redeeming, continue with Getting Started if you are new, or jump to Scripts only if you accept the account risks of automation tools.

Redeem early, spend deliberately, and let the rest of the wiki turn free Gold into stable clears.
