About this wiki
Ratatan Wiki is built by the community, for the community. Our goal is to keep the best information about rhythm commands, characters, bosses, weapons, builds and progression systems in one place that everyone can access for free.

What is Ratatan?
Ratatan is a rhythm roguelike action game developed by TVT Co. Ltd. and Ratata Arts and published by Game Source Entertainment. You command a Cobun army across the world of Redo, tap rhythm commands on the beat to issue orders, and stack Ratakaruta modifiers as each run pushes deeper toward The Everafter. It is the spiritual successor to Patapon, with original creator Hiroyuki Kotani on game design.
