In "We Love Katamari," players will find themselves in various new locations around Earth as the Prince and his cousins roll up different katamaris according to the fans’ requests. "We Love Katamari" continues the series’ trademark graphical style and musical excellence with an original soundtrack and hundreds of brand new items including Koi fish, angels and famous Earthly landmarks to roll up. The Prince’s celestial rolling has no boundaries; as his katamari grows larger, he can roll up literally everything in his path – from underwater creatures to mountains and even the Eiffel Tower itself!

Players can also roll with a friend in the all-new two-player cooperative mode. With each player controlling part of the clump, they will have to devise new strategies and communicate their rolling intentions in a new level of katamari madness. Battle Mode has also returned to "We Love Katamari" in extended form with three size scopes for competitive rolling action.
