Anime Astral Simulator updates

Astral Team schedules each Anime Astral Simulator update as a Roblox experience event, which means the release times are published by the studio before the update ships. This page reads them straight off that listing.

Release times

All times are UTC, taken from each update's own event listing. The summary column is Astral Team's wording, not ours.

Every earlier version

The table above covers the current release and what Astral Team has scheduled next. The history behind it comes from a second first-party source: the studio's own #game-logs channel, where the game owner posts full patch notes for every version and the old posts stay put — back to launch, with nothing missing. 29 versions in 94 days.

The headline column summarises the studio's notes rather than quoting them — several of those posts run to a few hundred lines. The dates and the version numbers are the studio's.

Two patterns worth knowing

Updates land at 20:15 UTC. Nearly every event recorded from the official feed opens within a minute of that same clock time. If you want to be online for a drop, that is the minute to be there — 21:15 in London, 16:15 in New York, 13:15 on the US west coast.

The outlier is worth knowing about, because it is the shape a slip takes: Update 10 opened at 20:45, half an hour after the usual slot, and one of the four codes it shipped with reads SORRY4DEL4Y! — the studio's own comment on the delay, not ours. When the slot slips it slips later the same day; none of the recorded events opened early, and none moved to a different date.

Whole numbers bring a map, half numbers bring fixes. Every full version is labelled Systems + New Map + QOL and every half-version Systems + Bug Fix + QOL. Updates 12 and 13 delivered maps; the scheduled Update 14 is labelled for one too. Updates 12.5, 13.5 and 14.5 are not. That distinction is the studio's own, repeated across the event listing, so it is a fair guide to whether a given update is worth clearing inventory space for.

The game's badge list backs it up from the other side, and it does it after the fact rather than on the studio's word. Astral Team creates a badge for each new world, and badges carry the timestamp they were made, so a map update leaves a dated trace nobody wrote for publication. Update 12 left exactly one: World 16, created 20:10 UTC on 29 August, five minutes before its event was due to open. Update 11.5 left none, which is what a half-version is supposed to look like.

The gaps run three to four days, alternating: 22 August, 25th, 29th, 1 September, 5th, 8th, 12th and 15th. At that cadence a new map arrives roughly once a week.

What Update 13 changed

Update 13 opened on 5 September 2026 with World 17, Kingdom of Lugunica: ten pets, seven avatars, a questline, a side quest, four accessories, one relic and a new world-boss title. Its main activity is Sanctuary Trials, three versions of the same raid set in the Past, Present and Future. One Sanctuary Key opens any version, but each timeline drops its own fragment.

Those trials feed the new SixFold Spirit Contract. Six spirits drop from their bosses and each boosts a different stat: Ia gives Power, Kua Yen, Aro XP, Ik Damage, In Luck and Nes Drop. Duplicate spirits raise that spirit to level 5; every six combined levels unlocks another equip slot. At 30 total levels the Perfect Sixfold Contract equips all six, strengthens them and awards the Spirit Knight title.

Update 13 also added Sanctuary Upgrades, up to four Commandment slots, a nine-item Relics of the Otherworld gacha reaching Astral rarity, Witch Progression, a one-click Max upgrade for relics, a Follow Party Retry setting, pet visual skins, two promotions, ten global quests, ten rankups and thirty achievements. Its five codes are on the codes page; the final two were appended to the studio's post after the first three appeared.

What Update 12.5 changed

The 1 September half-update added the Magic Squad gacha in Clover Island, paid with Magic Knight Tokens from Clover Raid and world enemies. Its eight squads run from Purple Orcas at Common to Black Bulls at Divine, with published power values from 1.25x to 15x. Promotion 35 now unlocks a second gacha slot, allowing separate machines to auto-roll at the same time with independent token pools and stop buttons.

The same patch expanded Player Stats from 13 lines to more than 70 across five tabs, exposing multiplier sources, luck-adjusted pull chances, pity progress and per-pool roll counts. It added a five-second DPS counter, granular Low Mode controls, two relic ascensions, a level-200 relic cap, a level-75 Genos cap and a Merit Stars leaderboard. The fixes include full gacha-speed scaling, working Star Speed runes and lighter teleports into raids and gamemodes.

What Update 12 changed

Update 12 opened on 29 August 2026 and its map is World 16, Tokyo Ward — one world, ten pets, seven avatars, a questline, a side quest and a world boss with its own title. The systems around it all run on the same material: a raid called Owl Suppression, 100 waves with a boss every fifth, entered with an Owl Key that the world's own enemies drop.

The part worth knowing is the kagune system. There is no machine to spin for one — every wave you clear in Owl Suppression hands you a free roll, so the gacha and the gamemode are the same activity. There are eight, one per rarity, and the one you equip is visible on your character. They then upgrade by feeding them RC Cells from the same raid, up to three boosts each, with the second and third only unlocking once enough cells have gone in — and each kagune keeps its own cells, so switching costs you nothing you already invested.

The full Update 12 write-up has the eight kagunes by rarity, the new Insane trial difficulty, the Friends leaderboard tab, the reworked Low Mode, the three codes it shipped with, and the follow-up post the owner added afterwards.

What Update 11.5 changed

The studio titled it MINI UPDATE 11.5 QOL, and most of it is exactly that. One thing in it is not: a new progression system called the Hunter License, started by talking to the examiner in Zaban City.

It runs from a base license up to three stars, and each rank is a permanent boost that stacks with the last. The base license gives Power, one star adds XP, two stars adds Drop, three stars adds Luck. Astral Team's own note is that the boosts you already hold get stronger each time you rank up, so a three-star license is worth more than those four rewards added together. It does not say by how much.

Each stage sets two tasks at once. One is always a hidden item you have to walk to and pick up yourself, and it only appears in the world once you have the task. The other varies — killing a specific enemy, reaching a wave in Zaban Rush, spending Yen, collecting an item. Nothing you did before accepting counts, so both start from zero.

The rest is quality of life, and the useful ones are: an Auto Spawn toggle on the Z City boss that keeps resummoning it about two seconds after each death and carries on while you farm elsewhere, stopping itself when you run out of keys; a search bar on the Exchange that matches both sides of a trade and accepts a world number or name, so typing 14 or tempest both work; Equip Best now handing your pet accessories to the right pets and applying the whole lineup at once instead of one pet at a time; and a new gacha, Humanity Arsenal, in Titan Wall (World 4).

What Update 11 changed

During Update 11 the experience title read [NEW RARITY] Anime Astral Simulator. Astral Team puts the headline feature in that bracket and changes it with major updates — it reads [SPIRITS] after Update 13 — so the new rarity was the studio's own framing of what Update 11 added, not a label inferred from the badges.

The game's badge list dates that precisely. Badges are created by the developer and carry the date they were made, so they act as a changelog the studio did not mean to publish. Four of them — World 12 through World 15 — were created on 22 August 2026, the day Update 11 opened, while Worlds 1 to 11 all date from 23 July.

Only one of those four is Update 11's map. The notes name a single new world, Zaban City, and list the other three under new badges (added missing ones): Lion Kingdom, Z City and Tempest Federation had already shipped in Updates 8, 9 and 10 and were simply missing a badge until that day. The 23 July cluster is the same effect — badges were only added to the game in Update 7, so every world built before then got its badge in one batch.

Two more badges share that 22 August date: First Pet Astral! and First Gacha Astral! The new rarity is called Astral, it applies to both pets and gacha pulls, and the name comes from the studio rather than from anyone's guess.

Codes

Every version in both tables above shipped with codes, and the studio posts them in a #codes channel in its own Discord on the day of the update. How soon varies more than you would expect: two minutes after the event opened for Update 11, two hours and six minutes for Update 11.5, and for Update 12 a minute before the slot it was scheduled for. They are listed in full on the codes page, filed by the update each one shipped with, along with the ones Astral Team has since retired.

Check this yourself

None of the above needs to be taken on trust, and it should not be. Open the experience page on Roblox, look under Events below the play button, and press See More. Every scheduled update is there with its own date, under the same titles used in the table above.

Expect to find finished updates still sitting there too — the feed keeps them for a while and we have not worked out the rule. On 26 August it was still listing Update 9.5 from the 11th, fifteen days old, as active. The schedule table here drops a version once the next one ships, so if you see rows on Roblox that are not here, those are the ones: look for them further down in the archive instead.

If a row here ever disagrees with what that page shows, the Roblox listing is right and this page is stale — tell us and it gets fixed the same day.

The day the game moved

Anime Astral Simulator's Roblox page says the experience was created on 14 July 2026. That date is real but it is not the launch — the game had already shipped thirteen versions by then. Astral Team re-uploaded it to a new experience that day, and the old one, place 113236157544232, is the link the studio printed in its own Update 1 notes back in June.

Three things make the move visible rather than assumed. The Update 8.5 notes state it outright — data migration from the old game's experience was switched off on 4 August. A patch three weeks earlier mentions players stuck on a migration screen. And the codes issued the day after the move read 2MVISITSNEW and LIKES3KNEW, because the visit and like counters had restarted from zero while the old experience was already past forty million visits.

It matters here for one reason: any site that reads the launch date off the Roblox API will tell you this game is younger than it is, and will have nowhere to put Updates 1 through 5.5. The archive above starts on 30 May 2026, the date of the studio's own release post.
