Ratatan guide
Ratatan.pro editorial team · Updated 2026-10-16
The loop
Pick a Ratatan, bring Cobuns, enter a world, and give commands on the beat. Between runs, spend materials in Rataport. The official Full Release FAQ explains Welcome Mode, Options > Audio > Calibration, Ratatan Dock, Support Desk, Oath Level, Goddess Games, and suspend save. Welcome Mode can be changed at any time but is disabled in co-op.
The community command page, checked 16 October 2026, documents Onbeat and Offbeat timing and the command labels Fall In, Jump, Attack, Guard, Hustle Tech 1, and Hustle Tech 2. Treat its mechanics as community documentation, not a complete current official command chart.
Where to go next
Start with how to play, then choose bosses, Cobuns, weapons, role comparisons, Ratakaruta cards, saves, PC settings, or campaign length. The role page is not an evidence-free S-tier ranking.
The 14 October v1.1.9 notes confirm Episodes 3/4, World 6 and its final boss, four new Dark Ratatan fights, and weapon level 100. The 16 October announcement acknowledges an Episode 3 progression bug and achievement issues. Do not assume an older five-world guide or an upcoming patch is the current full-release state.

Questions
Is there an official English strategy guide?
No. ratatan.wiki.gg was still a WIP shell on 16 October 2026. The detailed pages are on ratatanwiki.com in Japanese.
What is a Melodium?
The official English word for the magic instrument, 奏具. It is not the name of a character skill. The character ability is Ratatan Skill.
