Ratatan 1.0 Launches Oct 15: Patapon Successor Guide

Cute one-eyed Cobun soldiers marching in formation through a colorful world — Ratatan rhythm gameplay

Pata-pata-pata-pon! The rhythm-marching roguelike Ratatan hits version 1.0 today, October 15, 2026, exiting Steam Early Access and launching on Nintendo Switch 2, PlayStation 5, Xbox Series X|S, and PC. For fans of Sony's beloved PSP classic Patapon, this is the big one — Ratatan is its spiritual successor, built by the original creators.

After a last-minute delay from July and more than a year in early access, Ratatan is finally crossing the finish line. Here's what the game is, who's making it, and what to expect.

What Is Ratatan? Rhythm Roguelike, Patapon DNA

If Patapon's marching eyeball armies live rent-free in your head, Ratatan will feel like coming home. You play a pint-sized critter — a titular Ratatan — conducting an army of Cobun, one-eyed fuzzy soldiers, through colorful 2D worlds. You bark orders by drumming button commands to the beat: attack on the rhythm, defend on the rhythm, march on the rhythm. Keep the beat tight and your army grows stronger.

What makes it more than a tribute act is the roguelike layer. Each run through the world of Redo generates fresh challenges, and over 100 Cobun can be collected, customized, and taken into battle with different weapons and upgrades. Online co-op for up to four players lets whole squads march together.

From the Minds Behind Patapon

This isn't a clone by admirers — it's a reunion. Creative director Hiroyuki Kotani and composer Kemmei Adachi, two of the original minds behind Patapon at Sony Japan Studio, founded Ratata Arts to build a modern follow-up. The project began as a Kickstarter in July 2023, where 14,598 backers blew past the ¥20 million goal to raise nearly ¥220 million.

The soundtrack carries that same bouncy, chant-driven energy that made Patapon unforgettable — the kind of music you'll be humming for days.

The Delay and the Early Access Verdict

Ratatan was originally slated for July 16, 2026, but Ratata Arts pushed it to October 15 to squash bugs and polish multiplayer stability based on Early Access feedback. The Steam Early Access community has been kind: the game sits at 90% positive ("Very Positive") on Steam.

Critical first impressions are more mixed but affectionate. Reviewers praise the nostalgic charm and faithful Patapon feel while noting the roguelike structure doesn't always fully modernize the classic formula. In other words: if you loved Patapon, you'll love this — just don't expect it to reinvent the genre.

Platforms, Price, and Physical Edition

  • Launch date: October 15, 2026 (1.0 / full release)
  • Platforms: Nintendo Switch 2, PS5, Xbox Series X|S, PC (Steam)
  • Physical edition: Available on Switch 2 for $39.99 / £39.99

Note: versions for the original Switch, PS4, and Xbox One were cancelled along the way — Ratatan is current-gen (and Switch 2) only.

Why Ratatan Matters

Patapon was one of the PSP's most inventive first-party experiments, and its spirit has been largely absent from modern PlayStation. Ratatan picks up that dropped torch and marches it into a new era — with online co-op, roguelike depth, and the original creators at the helm. In a fall packed with blockbusters, it's the charming oddball worth your attention.

Tips for New Ratatan Players

If you're jumping in on day one, keep a few things in mind. First, protect your rhythm above all else — missing beats breaks your combo and leaves the Cobun vulnerable, so start on easier difficulties until the drum patterns click. Second, experiment with Cobun loadouts: different units counter different monster types, and the roguelike structure rewards adapting your army to each run's challenges. Finally, try co-op early — coordinating four conductors is chaotic, but it's easily the most fun way to play.

When does Ratatan 1.0 come out?

October 15, 2026. The game exits Steam Early Access and launches on Nintendo Switch 2, PS5, Xbox Series X|S, and PC the same day.

Is Ratatan a sequel to Patapon?

Not officially — it's a spiritual successor. But it's led by Patapon creator Hiroyuki Kotani and composer Kemmei Adachi, and it plays like Patapon in everything but name.

Does Ratatan have multiplayer?

Yes — online co-op for up to four players, each conducting their own Cobun army through the roguelike runs.

How is Ratatan rated on Steam?

Very Positive, with 90% of user reviews recommending it after more than a year in Early Access.
