October 15, 2026 — Ratatan’s 1.0 after a July slip for co-op polish
Ratatan ships Thursday, October 15, 2026 as a full 1.0 across PS5, Xbox Series, Switch 2, and PC. Ratata Arts and TVT — with Game Source Entertainment publishing — pushed the date roughly thirteen weeks past July 16 after Early Access feedback ballooned the fix list, especially online multiplayer stability.
The pitch is a rhythm roguelike side-scroller: march on the beat, fever when the timing sings, up to four players online, and a chaotic cast measured in the hundreds. Think Patapon’s pulse married to run-based action, not a PSP remaster cart.
Confirmed: Oct 15 current-gen launch — not PS4/Switch, not a Bandai Patapon sequel
Confirmed: delayed from July 16 to Oct 15 2026, Steam EA continues, Kotani collaboration, four-player co-op focus, Switch 2 (not Switch) on Nintendo. Not confirmed as NanaOn-Sha’s sole studio credit or that every Kickstarter stretch goal survives unchanged. Scrapers still listing PS4/Switch day-one are outdated.

They canceled Switch and PS4 so the rhythm co-op could afford to be good
Most delays just move a Friday. Ratatan also shrunk the platform matrix: licensing math for legacy hardware could not justify finishing those SKUs while shipping a full online title as an indie team. Switch 2 replaced Switch; PS4 left the sheet.
That honesty is the interesting calendar fact — October 15 is not only “more polish,” it is the date attached to a smaller, sharper hardware bet after ~100K Early Access players told them what broke in co-op.
Frequently asked questions
Quick answers about this release date.
1When does Ratatan launch?
October 15, 2026 for the 1.0 multiplat release — moved from the earlier July 16, 2026 date so Ratata Arts could finish bug fixes, online co-op stability, and polish after Steam Early Access feedback.
2Which platforms?
PlayStation 5, Xbox Series X|S, Nintendo Switch 2, and PC (Steam). Original Switch and PlayStation 4 SKUs were canceled so the indie team could fund quality on current hardware; Kickstarter backers were offered platform swaps.
3Is it a new Patapon?
It is a spiritual successor: rhythm-action DNA with four-beat inputs and fever highs, built with Hiroyuki Kotani (Patapon series designer) in the mix — but it is Ratatan from Ratata Arts / TVT, published by Game Source Entertainment, not a Bandai Namco Patapon 4 box.
4Do Early Access owners buy again on October 15?
No. Steam Early Access players keep access through the extended window and into 1.0 without a second purchase. Console buyers get the finished multiplat build on the October day.
