A massive leak of Steam achievements has revealed new details on dozens of upcoming games, including Kingdom Hearts 4. Revealed through the game’s Steam achievements are several new worlds for Kingdom Hearts 4, including one for the Star Wars franchise. While these worlds have not been officially revealed, the datamined Steam achievements points towards them being accurate to the final game.
Kingdom Hearts 4 was first announced back in 2022, and only showcased Sora in the new, original world of Quadratum at the time. While the game has been relatively quiet in the years since, Square Enix has started ramping up the details it’s willing to share about the game, starting with a new look at Kingdom Hearts 4 via a trailer out of the recent D23 expo. With a firm commitment to a 2027 release, the floodgates for Kingdom Hearts 4 are finally starting to open and leaks are slipping through the cracks.

It’s unclear if this is a complete list of Kingdom Hearts 4 worlds, but these are the ones that appear to have achievements tied to completing them in the game. Kingdom Hearts 4 is planned to release in 2027, so it’s likely that much of the game’s data has already been added to Steam’s backend if these achievements are available.
Kingdom Hearts fans will likely notice a few exciting new worlds aside from Star Wars among this leaked list. A world based on the Haunted Mansion and Zootopia are both making their Kingdom Hearts debut in the upcoming game. Additionally, returning worlds like Toy Story‘s Toy Box from Kingdom Hearts 3, and Hercules‘ Underworld from Kingdom Hearts 2 are also included in this leak.
Most interesting perhaps are the worlds titled “Monochrome Origins” and “Imagineer Planet.” The former could refer to the original black and white Disney cartoons like Steamboat Willie, and may be a world similar to Timeless River from Kingdom Hearts 2. Even more intriguing is the “Imagineer Planet” world, which could refer to Disney’s real-world engineers and park designers, who are known as “Imagineers.” With Kingdom Hearts 4 exploring the real world with the inclusion of Quadratum, it may be that Imagineer Planet is another nod to Disney’s real life theme parks.
