Anime Ultron Simulator Codes (Active and Expired)
Last checked August 4, 2026 (UTC)
Anime Ultron Simulator is on the Update 3.0 cycle and Nv Good Games drops a code with nearly every patch, apology, and milestone, so this list moves fast. I cross-checked every entry against Try Hard Guides and Beebom before posting it, and right now SOLO and SHADOWS are the two you want first.
Anime Ultron Simulator codes are the short strings Nv Good Games hands out for updates, like milestones, and the occasional server meltdown, and they pay straight into your grinding stash for free Gems, Dungeon Tokens, Exchange Tokens, dungeon Keys, and stacks of boost Potions. everything in Anime Ultron Simulator comes back to farming stronger units through dungeons and the exchange machine, so the free Keys and Exchange Tokens are the real prize here. Gems speed up your pulls, Potions multiply what you earn per run, and a code like SHADOWS that hands you ten of every key is basically a free evening of dungeon clears.
Quick tip. pop your Potions before a long dungeon session rather than the second you redeem, because they run on timers. I redeem the whole list in one sitting, bank everything, then burn the boosts in one focused grind. That gets far more value out of them than redeeming casually between matches.
Active Anime Ultron Simulator codes (20)
Every code below worked when I ran the full list against Try Hard Guides and Beebom on today's check. The game is generous right now, twenty live codes is a lot even by anime simulator standards, so clear the whole stack in one sitting.

If one comes back invalid, check that you actually joined the Nv Good Games community first, because that is the failure nine times out of ten. If you are in the group and it still refuses, the code likely just got retired and I will have it moved down on the next sweep.

Anime Ultron Simulator codes FAQ
What do Anime Ultron Simulator codes actually give you?
Gems, Dungeon Tokens, Exchange Tokens, dungeon Keys, and boost Potions. The Keys and Exchange Tokens matter most, since dungeons and the exchange machine are where the stronger units come from. Nothing cosmetic, it all feeds progression.
Why do my codes keep saying invalid?
Almost always because you have not joined the Nv Good Games Roblox community. The game silently rejects every code until you are a member. Join from the game's Roblox page, hop back in, and try again before assuming a code is dead.
Are the codes case sensitive?
Yes, and this list mixes styles freely. SHADOWS is all caps, Tensura is not, SummerPt2 and SummerPT1 differ by one letter's case. Copy and paste rather than typing, one wrong capital and the game rejects it.
When do new Anime Ultron Simulator codes come out?
With practically every patch. Nv Good Games ships codes for updates, like milestones, event parts, and even as apologies for shutdowns and delays, which is why the list is this long. Big updates like the current 3.0 cycle are the most reliable trigger.
Is there a code for Robux or free spins?
No. Rewards are in-game currency and consumables only, so treat any site or video promising Robux codes for this game as bait. The real codes all come from the developer's community posts.
How long do these codes last?
Longer than most. The developer has only retired one code so far, the launch Release code, and everything since has stayed live. Event-tagged codes like the Summer pair are the obvious candidates to die next, so redeem those first.
