How co-op works
Online co-op for up to four players synchronizes rhythm-based commands to control squads in side-scrolling battles. Teammates coordinate drum-pattern inputs to trigger attacks, movement, and abilities across roguelike runs.
About this game
Ratatan blends rhythm game mechanics with roguelike action, placing players in command of squads that respond to drum-pattern commands. Each run unfolds as a side-scrolling battle where timing and coordination determine every attack, movement, and defensive maneuver. With more than 100 characters available, the roster offers diverse unit types and tactical possibilities across procedurally generated encounters.

Gameplay revolves around inputting rhythmic sequences that translate into on-screen actions. Players issue commands in time with the beat, directing units to charge, retreat, or unleash special abilities. Online co-op intensifies the challenge as four players must align their inputs, balancing individual timing with group strategy to maintain momentum and avoid breaking the rhythm chain.
The roguelike structure ensures each session brings new enemy formations and loot opportunities. Progression between runs unlocks additional characters and upgrades, encouraging experimentation with different squad compositions. Communication-heavy teamwork and run-based replayability make every attempt a test of synchronized execution and adaptive tactics.

Frequently Asked Questions
How many players can team up in co-op?
Ratatan supports online co-op for up to 4 players. You'll need to coordinate your rhythm inputs together, so timing and communication become crucial when playing with a full squad.
How does the rhythm mechanic work in co-op?
You input drum-pattern commands in time with the beat to control your units-attacking, moving, and defending based on your timing. In co-op, all four players need to sync their inputs to maintain the rhythm chain and keep momentum going, which makes teamwork essential.
Does progression carry over between runs?
Yes. While each run is procedurally different enemy formations and loot, you unlock new characters and upgrades between attempts. With over 100 characters available, you can experiment with different squad compositions as you progress.
Is voice chat or communication important for co-op?
Absolutely. Since all players need to align their rhythm inputs and coordinate tactical decisions in real time, communication makes a huge difference. Staying in sync and calling out commands or strategies helps maintain the rhythm chain and prevents breaks in your combo.
