Everything you need to march your Cobun army from Redo to The Everafter.
What is Ratatan?
Ratatan comes from TVT Co. Ltd. and Ratata Arts, the studio founded by members of the Patapon team, including original creator Hiroyuki Kotani. Instead of tapping drum beats on a fixed march, you steer your Ratatan freely across a side-scrolling battlefield and punch in rhythm commands on the beat to send Cobun charging, retreating or concentrating fire.
Four-Beat Rhythm Commands
You move freely and issue orders on the beat. Land the input inside the rhythm window and your Cobun respond instantly; miss it and the whole line hesitates.
Cobun Armies
Chorus become Cobun once a Ratatan gifts them a Medama. Each character reshapes the army, so your roster choice changes how a stage plays out.
Ratakaruta Stacking
Roguelike modifiers that define a run. Hold two of the same element to trigger an Elemental Force, capped at three active Forces out of six elements.
Online Co-op and Crossplay
Teams of up to four play online with room codes or platform invites, and cross-play covers Steam, Nintendo Switch 2 and Xbox Series X|S.
Each run sends you deeper into a world of episodic stages toward The Everafter, where the Goddess is said to live. Between runs you bank tokens into the Ratatan Dock, unlock higher Oath Levels to reach later episodes, and gamble Goddess's Lottery pulls for the Mythic weapons and Decorune that carry you through the eight assembled Dark Ratatan and the story's final boss. The full 1.0 release arrived on October 14, 2026 after roughly a year in Early Access, adding Episodes 3 and 4, World 6, the complete Dark Ratatan roster and new Mythic gear.

Frequently Asked Questions
What should I do first in Ratatan?+
Finish the tutorial stages so the rhythm command window is explained, then immediately check Options, Audio and Calibration to fix your input timing before you blame the game for missed beats. Play your first runs on the default difficulty, learn how the Melodium redirects your Cobun line, and only after your first clear start spending tokens at the Ratatan Dock. Setting the Oath Level in Goddess Games unlocks Episode 2, so treat that as the real end of the tutorial rather than an optional extra.
How do Ratakaruta and Elemental Force work?+
Ratakaruta are the run-defining modifiers you pick up between stages. Hold two Ratakaruta of the same element and you gain that element's Force effect, and you can keep up to three active Forces at once out of the six available elements. Because the cap is three, most strong runs intentionally commit to two or three elements instead of collecting one of everything, and the Lightning Force is generally the most consistent because Shock application and Autocharge+ turn status effects into MP sustain.
How many bosses are in Ratatan and which is hardest?+
The 1.0 release assembled all eight Dark Ratatan, and each world also has mid-bosses such as Captain Barbatoid of the Paraddean Sea and Scorpswoosh Bill of Yeehawler Mountain. Episode 4 closes the arc with the final boss in World 6. Difficulty depends heavily on your Ratakaruta setup, but the Hard Boss modifier escalates any encounter, and the Target Timer phase event is the usual run-ender because missing the timed objective hides the reward chest.
Which characters and Ratakaruta are strongest?+
Community rankings put Barrier Swell MP regeneration, Chilly Challenge strength above 75% HP, Autocharge+ MP recovery near Shocked enemies and Whirlwind Strike critical chance on normal attacks at the top of the Ratakaruta pool. Among characters, Keroronpa is the loudest support pick, Nyandola bursts single targets as an assassin, Mimizukyun locks on from range as a sniper and Harigittan anchors a defensive line. Balance patches move these values, so confirm the tier list after every update before you commit resources.
How does Ratatan multiplayer work?+
Open the multiplayer menu, choose friend matchmaking and share the room code, or skip the code on Steam, PlayStation 5 and Xbox Series X|S by using that platform's own invitation feature. Cross-play covers Steam, Nintendo Switch 2 and Xbox Series X|S, with PlayStation 5 cross-play planned. Console play needs Nintendo Switch Online, PlayStation Plus or a Game Pass tier with online multiplayer. There is no local split-screen, and Welcome Mode is disabled once a second player joins.
What should I upgrade first at the Ratatan Dock?+
Adventure upgrades at the Ratatan Dock and the Support Desk come first because they are the difference between a wall and a clear when you keep dying on the same stage. Cosmetics can wait. After that, raise your Oath Level each time you want to reach the next episode, and spend Goddess's Lottery pulls deliberately because from Episode 3 onward the altar pools change. Bank Goodie Gate pickups and use suspend saves carefully, since 1.0 fixed cases where already-collected items could be re-obtained after resuming.
Which platforms can play Ratatan and does progress carry over?+
The 1.0 release launched on PC via Steam, PlayStation 5, Nintendo Switch 2 and Xbox Series X|S, with versions for the original Nintendo Switch and for GOG in preparation. Early Access save data continues to work in the full release, and requirements you already completed during Early Access retroactively unlock the matching achievements. On consoles, online play requires the platform subscription, and multiplayer progress still saves to each player's own save file rather than a shared host save.
