On July 25, 2025, Ratatan— the eagerly awaited spiritual successor to Sony’s beloved Patapon series— will drum its way into Steam Early Access. Created by Ratata Arts under the direction of Patapon veteran Hiroyuki Kotani and featuring a score by composer Kemmei Adachi, this roguelite rhythm-strategy hybrid blends twitch-based drumming mechanics with procedurally generated stages and four-player online co-op.
If you’ve ever tapped your foot in time with Patapon’s iconic drum calls, Ratatan will feel both familiar and fresh. The game adopts the same charming 2D silhouettes and on-beat commands—“Pata-Pata-Pata-Pon!”—but injects roguelite progression into each run. Levels, enemy formations, traps and treasures are all shuffled by a procedural generator, so no two expeditions into Ratata territory ever play out identically.
Each failed drumming sequence can cost you cobun soldiers, shrinking your unit count on the field. Yet land enough perfect rhythms, and you’ll unleash Fever Mode, powering up the entire squad with damage boosts, speed surges or healing pulses. On successful runs, leftover resources feed into a meta-progression tree, unlocking new drum patterns, unit classes and environmental modifiers for subsequent attempts.
One of Ratatan’s biggest departures is the emphasis on online multiplayer. Up to four players can now take up drumsticks together, coordinating combos to trigger massive team-wide effects. “We wanted that sense of communal pulse,” says Kotani. “Hitting that perfect chain in unison is like casting a spell.”
The free demo currently offers two introductory worlds, giving solo explorers or small groups a taste of procedural combat. In playtests, perfectly synced Fever Mode activations light up the battlefield, while mistimed inputs or spotty connections can leave your cobun army scrambling. Ratata Arts has promised to refine netcode and timing windows throughout Early Access, based on closed feedback channels with backers.
Kemmiei Adachi’s soundtrack marries tribal percussion with electronic flourishes, evolving dynamically based on in-game performance. Early feedback highlights the catchy motifs that ramp up intensity as players string together combos. Visually, the game retains a high-contrast silhouette aesthetic, accented by vibrant particle effects whenever power-ups or boss attacks erupt.
Ratatan’s journey began on Kickstarter, where the project raised over $1.2 million from more than 25,000 backers. Many contributors have since joined closed alpha tests, offering suggestions ranging from fresh enemy archetypes to QoL improvements like adjustable input latency settings. “Our backer community feels like an extended development team,” Kotani notes.
Throughout the Early Access window, Ratata Arts plans bi-weekly patches. Roadmap highlights include new worlds, boss échelons, additional unit types and community-requested challenge modes. Developer livestreams and play sessions will keep fans in the loop as the team polishes core systems ahead of a full release.
At its heart, Ratatan aims to revitalize niche rhythm-strategy gameplay for a modern audience. If Ratata Arts can sharpen network performance, diversify procedural encounters and expand co-op balance, Ratatan may well spark a new wave of drum-based adventures. We’ll be on hand for launch-day analysis, interviews with the development team and deeper dives into this marching movement when Early Access goes live on July 25.
