A substantial leak originating from Steam achievements has seemingly revealed multiple worlds slated for inclusion in the highly anticipated Kingdom Hearts 4. Websites like Exophase, which tracks game achievements, and SteamDB, a Steam database, have reportedly acquired achievement lists for unreleased titles, including Square Enix's upcoming action RPG.
The leaked achievements offer significant clues about the destinations Sora and his companions will visit. Evidence suggests a journey to a "Galaxy Far, Far Away," hinting at the inclusion of Star Wars content, and the Haunted Mansion will also feature, as directly indicated by an achievement description. The Toy Box world is set to return, and Zootopia will make its debut, with Savanna Central being referenced.
Additionally, the world of Coco, Land of the Dead, which was previously announced, appears in the leak. The game will also revisit Quadratum, the surreal, Tokyo-inspired setting introduced in Kingdom Hearts 3 as the backdrop for the fictional Verum Rex game. A new world named Monochrome Origins is also mentioned. It is theorized by Reddit users that this world will be the home of Oswald the Lucky Rabbit, based on the achievement "Hotsy-Totsy Helper-Outer" and the character's known catchphrase.
Further speculation points to the inclusion of the WALL-E character. An achievement titled "It's Not Junk To Me" requires players to "fill up the treasure collection of the custodian for a certain Quadratum rooftop." This has led to the interpretation that the custodian could be WALL-E, a robot known for collecting and treasuring discarded items.
Another world mentioned is the "Imagineer Planet." While its direct connection to existing Disney media is unclear, it is likely linked to Walt Disney Imagineering, the research and development arm of Disney theme parks. The achievement associated with this world, "Planet Producer," only requires completing any mission, unlike other world-based achievements that necessitate finishing all tasks. This could imply that the challenges within the Imagineer Planet are either exceptionally numerous or significantly more difficult.
This extensive leak reportedly extends beyond Kingdom Hearts 4, encompassing achievement lists for other anticipated titles such as Judas, Persona 6, and unannounced games based on existing IPs. The source of this data breach is believed to be an error on Valve's part, which made private achievement lists publicly accessible via the Steam API. This error allowed sites like Exophase to scan and record information for games that had not yet been officially revealed or detailed.
