Tippytap, badaboom and "Ratatan" across the battlefield in this latest roguelike adventure from the creators of the beloved rhythm classic, Patapon! March across the world of Redo, build your Cobun army, and combine forces with your closest chums to defeat any evildoers silly enough to stand in your way!

Players can move to the groove alone or team up with friends in online multiplayer mayhem suitable for up to four players! Engage in huge melee brawls with more than 100 characters duking it out for supremacy. Defeat your enemies by riding the rhythm of Ratatan's catchy soundtrack in this delightful, heartfelt adventure!

In the vast and peaceful sea lies Rataport, a vibrant island bustling with life. Here, the Ratatans, mysterious yet charming creatures, live in harmony with their friends. Though they differ in appearance and personality, they share a single dream: to journey to The Everafter and meet the legendary Goddess said to reside there. Fueled by hope, the Ratatans set out on their adventure, undeterred by failure, determined to one day stand before her.

The Ratatans are groove-loving adventurers that use the power of song and magical instruments called Melodium to command their armies of Cobun. Lead your troops by issuing rhythmic commands, guiding them through massive dynamic battles where strategic positioning, timely orders, and well-planned retreats will be the key to your success!

Developer Ratata Arts is excited to announce that Ratatan will launch in Steam Early Access on September 19, 2025, beginning at 12:00 a.m. JST / 3:00 p.m. UTC / 8:00 a.m. PDT.

The announcement was made as a surprise during an exclusive Ratatan Play Session held on August 7 in Tokyo. The event brought together members of the Japanese press and streamers, who enjoyed hands-on time with the latest build, a talk session with the development team, one-on-one interviews, and even a live DJ set featuring new tracks from the game — creating a lively and memorable atmosphere.

Newly Revealed Content

World 3: Jam Jammer Jungle Journey
 A dense jungle where the ruins of ancient drums lie hidden. Swamps and fierce wildlife stand in the way, while deep within, the priestess Tolja So prepares a dark ritual to resurrect an evil god.

World 4: Frozen Flower Fantasia
 A garden of eternal spring… or so it seems. Now completely frozen over, this frigid domain is ruled by the icy Glaciera and her loyal followers.

New Ratatans
 Several previously unrevealed Ratatans made their debut during the event. New weapon types — including staves, bombs, scythes, and hammers — will add greater variety to the battlefield.

"To everyone who joined us at the event and all those supporting us online — thank you so much. With the Early Access version, we’ll be incorporating your feedback to make Ratatan even better. Let’s make this world an amazing one together!" said Producer Kazuto Sakajiri.

On Sunday, 14th September, just days before Early Access begins, a special livestream will be held on the YouTube program “AGRS Channel”, hosted by voice actor Tomokazu Sugita.

The stream will feature the latest updates, our post-launch roadmap, and information on upcoming events — so be sure to tune in!

Feel the beat and use rhythm commands in time with the music to order your Cobun in the direction you want them to go. The Ratatan can be moved freely, so use your better judgment to decide where best to give orders, where to stand when on the offensive, and when to retreat. A sense of rhythm and strategy is crucial in order to survive long adventures while losing as few Cobun as possible!

Keep to the beat and your party will enter FEVER MODE, a feature no good rhythm game can do without! Feel the vibes shift as the background music dynamically changes and your Cobun erupt in a flurry of frenzied dance moves that'll really get the heart pumping! And if everyone's party goes into FEVER MODE at the same time, you'll really bring the house down!

Ratatan makes use of charming 2D animation with movements filled with vivid personality. The Cobun, your faithful and lovable servants, will wibble-wobble as they follow your orders, while your enemies will try to intimidate with their often hilarious movements, breathing even more life into the world of Ratatan.

Now, what kind of troupe would you be leading without the perfect tune to march your minions to?! Worry not! We've got you covered with the perfect musical accompaniment by veteran composer Kemmei Adachi for crushing your enemies in a wave of adorable terror!

Ratatan features 100+ controllable characters, rhythm-driven combat, and a vibrant world of music, monsters, and multiplayer madness. The soundtrack features music by veteran composer Kemmei Adachi, with a special guest track by David Wise.

Ratatan is in development for Nintendo Switch, PS4, PS5, Xbox Series X|S and PC (Steam).
