Kaiju Alpha Hub — Game Status, Codes & Guides

By Money Lord — Founder & Editor | Updated: August 19, 2026

Kaiju Alpha was an action-battlegrounds experience by the Roblox group SULU KAKA in which players took control of building-sized kaiju and fought in destructible arenas. As of August 19, 2026 it is no longer available on Roblox — so this hub now exists to tell you that plainly, keep the historical record honest, and point you at kaiju games that are still live.

Kaiju Alpha status: unavailable on Roblox

The standard Roblox liveness test is a redirect check. Request roblox.com/games/{placeId} with no slug: a live experience answers 301 and redirects to its own name, a removed one answers 302 and lands on /Title-Unavailable, and a place ID that never existed answers 302 to a generic request-error?code=404. On August 19, 2026 Kaiju Alpha's place ID 139769003880269 returned the middle case: 302 → /Title-Unavailable. We control-tested live games in the same minute and got the expected 301 to their own slugs, so the check itself is working.

The API agrees. Querying the games endpoint for the Kaiju Alpha universe on August 19, 2026 returns the name [TITLE UNAVAILABLE], creator [UNKNOWN], zero players, zero visits, and the universe flagged as restricted from public access. The last time we saw the game healthy was our July 31, 2026 check, when it was running Update 40 with roughly 9,100 players online.

Roblox does not publish a reason when an experience goes unavailable, and we are not going to invent one. Be aware that search engines are actively wrong about this right now: several indexed pages and even the Roblox game link itself still appear in results as though the game were live and updating. An indexed URL is not evidence that a game loads — the redirect test is.

What’s next for Kaiju Alpha?

There is no developer statement. We could not find any post from SULU KAKA, on the Roblox group feed or anywhere else, acknowledging the removal, and we are not going to paraphrase a rumour into a plan.

Two dated facts are worth recording. First, the community wiki was being edited as recently as August 14, 2026 (the last revision was to the Godzilla Ultima page) with no mention of a shutdown — the editors were still documenting kaiju as normal, which puts the removal somewhere in the last few days rather than weeks ago. Second, the same wiki’s history section records that Kaiju Alpha was already off Roblox once before and came back on May 27, 2026. That is a precedent, not a promise, but it does mean an unavailable Kaiju Alpha has not historically been a permanent one.

We re-run the liveness test on this game on every content sweep. If the experience returns, this hub and the Kaiju Alpha codes page are updated the same day — including the first genuinely verified code, if SULU KAKA ever adds a redemption menu.

All Kaiju Alpha guides

These are the two Kaiju Alpha pages we publish. Both have been updated to reflect the game’s current unavailable status — nothing on either page asks you to go and play right now.

Kaiju Alpha in numbers (historical)

None of these figures are current. They describe a game that is no longer on the platform, and each one carries the date it was measured.

The players and visits figures come from our own Roblox API read on July 31, 2026, the last date the game was live for our checks. The favourites and rating figures are the final recorded totals: the vote and favourite counters for the universe still respond even though the experience does not, and on August 19, 2026 they returned 170,904 favourites and 120,231 up-votes against 6,623 down-votes, which works out at 94.8%. Treat those as the numbers the game finished on, not as live traffic.

For the record, the developer was the Roblox group SULU KAKA, the genre was action battlegrounds, and the last update we verified in-game was Update 40 on July 31, 2026 — the developer never published patch notes as such, only rewrites of the Roblox game description, so the update history is not fully recoverable.

Live kaiju games to play instead

These are different games by different developers — not Kaiju Alpha sequels, spin-offs or re-releases, and we do not know of any connection between their teams. We ran the same liveness test on all three on August 19, 2026 and each one answered 301 to its own slug:

• Kaiju Universe by Prometeo Games — the biggest of the three at 768.3 million visits (August 19, 2026), and it runs a real code system: see Kaiju Universe codes.
• Kaiju Paradise by LAMINAX CO. — a survival-horror take rather than a battlegrounds one, 304.9 million visits (August 19, 2026). Codes: Kaiju Paradise codes.
• Kaiju Multiverse by EMJES — the closest in feel to Kaiju Alpha’s monster-vs-monster combat, 43.8 million visits (August 19, 2026). Codes: Kaiju Multiverse codes.

Frequently asked questions

Is Kaiju Alpha still playable on Roblox?

No. As of August 19, 2026 the experience is unavailable. Place ID 139769003880269 answers 302 to a Title Unavailable page instead of the 301-to-own-slug a live game returns, and the games API reports the universe as [TITLE UNAVAILABLE] with zero players and zero visits. Search results and cached links that still show it as live are stale.

Why was Kaiju Alpha removed from Roblox?

Roblox does not publish a reason when an experience goes unavailable, and SULU KAKA has published no statement we can find. We will not guess at one. What is documented is that the community wiki records the game being off Roblox once before and returning on May 27, 2026.

Did Kaiju Alpha ever have working codes?

No. There was no Codes button and no text field to type into when we checked the game in-game on July 31, 2026, so every Kaiju Alpha code list published elsewhere is invented. The full evidence is on our Kaiju Alpha codes page, and our method is documented in how we verify codes.
