All Star Tower Defense remains one of Roblox's enduring anime-inspired tower defense experiences, and its September 2026 code selection offers useful resources for players building out their unit rosters. Whether someone is putting together a first capable squad or chasing the materials needed for another summon, the currently listed rewards deliver a sizable batch of Gems and Stardust, plus one unusual special unit.
There are three active All Star Tower Defense codes in this update. Redeeming every one of them gives players 12,000 Gems and 300 Stardust in total. The beginner-focused code also includes an Otherworldly Pickle. As with many promotional codes in live Roblox games, these offers can disappear without much warning, so the sensible move is to enter them while they are still active.
The rewards matter because Gems and Stardust support the process of summoning new units. In a game centered on preparing a team for increasingly demanding stages and boss encounters, an extra injection of summoning currency can help players pursue new options, improve the depth of their roster, or simply recover after an unlucky run of pulls.
Active All Star Tower Defense codes
The following codes are listed as active as of September 9, 2026. Codes must be entered exactly as written, including capitalization.
For useful background on this topic, read Professor Layton and the New World of Steam Sets December 2026 Release.
- ReturnOfTheLobbies -- 4,000 Gems and 150 Stardust
- ALateSummerAwaits -- 4,000 Gems and 100 Stardust
- AwesomeBeginnerCode -- 4,000 Gems, 50 Stardust, and 1 Otherworldly Pickle
That makes ReturnOfTheLobbies the best individual choice for Stardust among the currently active set, while all three provide the same 4,000-Gem payout. There is no reason to choose between them, however: each code can be claimed once, allowing their rewards to stack.
AwesomeBeginnerCode is especially notable because it grants a unit in addition to currency. Special code units can range from novelty additions to genuinely useful characters, and the Otherworldly Pickle is a reward worth collecting even for players who are primarily after Gems and Stardust. A unit reward should also be more obvious than a currency-only claim, as it can trigger a pop-up after successful redemption.
How to redeem ASTD codes
The code redemption process takes place inside All Star Tower Defense rather than through a separate Roblox page. It only takes a few steps:
- Launch All Star Tower Defense.
- Select the Settings button in the upper-left corner of the screen.
- Look at the bottom of the Settings window for the code entry field.
- Type or paste an active code exactly as displayed.
- Press Enter, or use the equivalent input command on the platform being used.
Players should not expect a large confirmation banner after every successful claim. Currency redemptions do not necessarily produce an on-screen success message. Instead, check the Gem and Stardust totals visible beneath the Settings window after submitting a code. If the numbers increase, the redemption worked. A code that awards a unit is more likely to display a dedicated notification.
This understated confirmation method makes it worthwhile to check currency totals before and after entering each code. It can prevent confusion when a player has successfully redeemed a reward but did not see an obvious visual acknowledgement. If the totals do not change, double-check the spelling, capitalization, and whether the code has already been used on that account.
Why Gems and Stardust are valuable
All Star Tower Defense is built around assembling a lineup of anime-styled champions and deploying them against waves of enemies. That basic tower defense loop places a premium on roster growth. New units can create additional strategic possibilities, while a wider selection of characters can help a player adapt to different encounters and boss fights.
Gems and Stardust are both tied to summoning units, which is why even players who have been with ASTD for years can benefit from a fresh code drop. For newer players, a few thousand Gems can make an immediate difference when establishing a usable team. For veterans, Stardust and Gems can still contribute toward another attempt at expanding or refining their collection.
The game has maintained an audience for more than six years despite the crowded field of Roblox anime tower defense titles. Longevity alone does not guarantee that every player will enjoy it, but it does mean ASTD has continued to give fans a reason to return, build teams, and test them against the next challenge. Promotional rewards fit naturally into that routine, offering a quick way to reduce some of the resource pressure around summoning.
Redeem the codes promptly
All Star Tower Defense codes are temporary. The three codes above are active in this September 2026 update, but there is no stated expiry date for any of them. They could remain available for a while, or they could be removed when the next event, lobby change, or game update arrives.
That uncertainty is the key reason to claim them as soon as possible. There is little advantage in saving a code for later, since its listed rewards are fixed and redemption does not require players to spend anything. Entering them now ensures the Gems, Stardust, and Otherworldly Pickle are attached to the account before the promotion ends.
Players returning after a break should be particularly careful. It is easy to see a code list, plan to redeem it later, and discover that the promotion has vanished by the next login. The same issue applies to players who are waiting for a better summoning banner or a future unit release. Claiming the currency does not force an immediate summon; it simply makes the resources available when the player decides to use them.
Expired ASTD codes to avoid
The following codes are no longer active. They are useful as a reminder that even generous ASTD giveaways eventually expire, but entering them now will not deliver their former rewards.
- FusionReborn -- formerly 4,000 Gems and 150 Stardust
- TheOverlordArrives -- formerly 4,000 Gems and 250 Stardust
- WhoInvitedThisGuy -- formerly 4,000 Gems and 250 Stardust
- tboicats -- formerly 3,000 Gems and 170 Stardust
- sorryfordelayandmonkeyking -- formerly 4,000 Gems and 280 Stardust
- yickadee -- formerly 2,000 Gems and 230 Stardust
- twete93dont -- formerly 2,700 Gems and 170 Stardust
- tungtungnobannersahur -- formerly 2,700 Gems and 170 Stardust
- cosmicrebel -- formerly 2,700 Gems and 170 Stardust
- omgupdate2026 -- formerly 2,700 Gems and 170 Stardust
- fordanielxd -- formerly 67 Gems and 67 Stardust
Expired codes are not a sign that something is wrong with an account or the redemption screen. They simply reflect the rotating nature of promotional rewards. If an older code fails, move on to the active list rather than repeatedly trying to submit it. Players may also encounter outdated code lists in community discussions, so checking the most recent active selection before entering a batch can save time.
September 2026 ASTD code recap
For now, the current All Star Tower Defense code list is short but valuable. ReturnOfTheLobbies, ALateSummerAwaits, and AwesomeBeginnerCode collectively provide enough Gems and Stardust to give summoning plans a meaningful boost. The final code's Otherworldly Pickle also adds a special-unit incentive beyond the usual currency haul.
Open Settings, find the redemption field at the bottom of the window, and enter each code with the correct capitalization. Then watch the currency totals for confirmation. With ASTD codes known to expire over time, claiming this trio promptly is the safest way to make sure those 12,000 Gems, 300 Stardust, and the Otherworldly Pickle do not slip away.
