About Once Upon A KATAMARI
Once Upon A KATAMARI delivers a fresh Katamari Damacy adventure that adds new eras to explore and a brand‑new soundtrack. Players roll a growing katamari through periods such as the Jurassic, Ice Age, and historic Japan while trying to restore the sky’s scattered stars after the King’s accidental destruction.
The title introduces a magnet tool, extensive cousin selection with visual customization, and a four‑player KatamariBall mode that can be played online or against CPU opponents. It runs on Windows with full controller support, Steam achievements, cloud saves, and family sharing.
01 / THE GUIDE
New Stages and Soundtrack
The game announces “new stages and a fabulous new soundtrack,” expanding the rolling experience beyond earlier entries. Each stage presents a distinct visual theme that matches its historical period, giving players fresh environments to collect objects.
The accompanying music is described as “fabulous,” implying that each era’s soundtrack is tailored to its setting. This pairing helps players identify the current stage by auditory cues as they progress.
- Listen for changes in the music to confirm you have entered a new era.
- Survey the entire stage to locate objects that match the period’s theme.
02 / THE GUIDE
Magnet Tool
A “magnet to draw in nearby objects” is listed as a never‑before‑seen support tool. When activated, it pulls surrounding items toward the katamari, allowing rapid growth in dense clusters.
The description notes the tool’s effect is limited to “nearby objects,” so timing its use when surrounded by many small items maximizes its benefit.
- Activate the magnet in areas with a high concentration of tiny objects.
- Reserve the magnet for tight corridors where manual rolling is slower.

03 / THE GUIDE
Rolling Through the Ages
Players travel “through the Jurassic Era, Ice Age, historic Japan, and more eras” to rebuild the sky’s dazzling field of stars after the King’s mishap. Each era supplies period‑specific objects for collection, such as dinosaurs or ancient artifacts.
The narrative links the rolling mechanic to a restoration goal, giving purpose to gathering items across time and tying each visual style to the overall star‑rebuilding objective.
- Prioritize era‑specific items for higher point values.
- Use the magnet in eras with many small debris to speed up growth.
04 / THE GUIDE
Cousin Customization
The game lets you “play as The Prince, or choose among his 68 cousins and kin,” each of which can be recolored and given a new face. This creates a large pool of visual variations for player avatars.
Customization is purely cosmetic; it does not alter gameplay mechanics but allows players to personalize their character’s appearance before rolling or competing.
- Select contrasting colors to make your katamari easier to track in multiplayer.
- Save favorite designs for quick access when joining online matches.
05 / THE GUIDE
Celestial 4‑Player KatamariBall PvP
“Compete in Celestial 4‑Player KatamariBall” adds a galactic sport mode where up to four players roll simultaneously. The mode supports both online matches against other players and offline matches against CPU opponents.
This competitive layer lets participants hone skills in solo practice before testing abilities against human opponents, providing a distinct multiplayer experience from the single‑player rolling stages.
- Practice offline first to learn arena layouts and item spawn patterns.
- Coordinate movement with teammates in four‑player matches to control space.
