What is Kaiju Alpha?

Kaiju Alpha is a Roblox kaiju fighting and progression game by SULU OPPA. You pick a kaiju, spawn onto one of five islands, and flatten buildings and other players for cells and XP — then spend the cells on the next kaiju, or on Limit Break, which lifts a kaiju's level cap to 200. Servers hold 25 players, and the endgame is a short list of very expensive kaiju gated behind levelling other kaiju first: Destoroyah Final Form wants 1,500,000 cells plus two other forms at level 100 with 100 kills each.

The place people are playing right now was created on 17 August 2026 and has already taken 6,037,970 visits at a 94.5% like ratio — but the game itself is years older, and is currently on Update 45. That gap is why so many Kaiju Alpha guides read wrong: several of the biggest are still describing an Update 24 meta from May. Everything here is keyed to the live place — the update log carries Update 45's actual stat changes, the kaiju list says "not published" instead of guessing, and what happened to Kaiju Alpha untangles the August place change with dates.

Get Started in 5 Steps

  1. Redeem the codes first. One of the codes live right now pays 30 million cells and 30 million EXP, which is more than any farming session will give you this week. The codes page has the redemption steps — the field is at the bottom of the OPTION panel and there is no confirm button, which is where most people get stuck.
  2. Learn the two roars before you need them. R roars standing still, T roars moving, and you cannot attack while roaring. Full keybinds are on the controls page.
  3. Farm on the right island. Tokyo has the most buildings and the most people trying to kill you; the Forest has no buildings at all, but its trees pay cells and XP just the same. Pick by how much interruption you can tolerate — see cell farming.
  4. Buy Biollante at 50,000 before anything else in that bracket. Wide area damage and 4,900 HP is what lets you sit inside a crowd and keep earning, and every later unlock is paid out of that income. Prices for everything else are on unlock requirements.
  5. Pick one endgame chain and commit. Space Godzilla and Destoroyah Final Form want different kaiju levelled to 100, so splitting your time means arriving at neither. The tier list explains what each one buys you.

FAQ

Is it Kaiju Alpha or Kaiju Universe?

They are two different Roblox games. Kaiju Universe has been the default answer to "Roblox Godzilla game" for years, so people often assume Kaiju Alpha is a successor or a rename. It is not — Kaiju Alpha has its own history going back to at least 2022, and the roster overlap comes from both drawing on the same films.

Is Kaiju Alpha gone or banned?

It is live. The experience most people are playing was created on 17 August 2026 under the group SULU OPPA and has passed 6 million visits. If an old bookmark 404s, it is pointing at the previous place. See our what happened page for the dated timeline.

Does Kaiju Alpha actually have codes?

Yes. The official experience description for Update 45 lists "New code in #Code" among its patch notes, which is the developers pointing players at their own Discord channel. Some guide sites still argue the game has never had codes; that argument is built on captures taken before this update.
