Steam Achievements Leak Reveals Spoiled Worlds for Kingdom Hearts 4

Exophase, a platform for tracking video game achievements, and SteamDB, a comprehensive database for Steam content, have reportedly received a significant number of achievement lists for unreleased Steam titles. Among the most exciting is Kingdom Hearts 4, which is set to launch in late 2027.

While not every achievement in the leaked list for Kingdom Hearts 4 comes with a description, several provide intriguing hints about the worlds Sora and his friends will explore in this upcoming Disney action RPG.

The Star Wars universe seems to be confirmed, with the achievement “Desert Do-Gooder” referencing a “Galaxy Far, Far Away.” Additionally, the Haunted Mansion is explicitly mentioned in another achievement. Toy Story is making a comeback, as the Toy Box world appears again, and Zootopia is set to debut, with Savanna Central noted. The Land of the Dead from Coco is also included, which was previously revealed at D23.

Players will also revisit Quadratum, the Tokyo-inspired world introduced in Kingdom Hearts 3, accessible through Toy Box, which served as the backdrop for the fictional game Verum Rex. A new world called Monochrome Origins is hinted at in the achievement “Hotsy-Totsy Helper-Outer.” While it doesn’t seem to connect to any existing Disney property, Reddit user Quiccies speculates that it may be where players encounter Oswald the Lucky Rabbit, as “hotsy-totsy” is his catchphrase in other Disney games.

Another Reddit user, Kurai_46, has pointed out that Wall-E is likely to appear in Kingdom Hearts 4 as well. Although not named directly, the achievement “It’s Not Junk To Me” tasks players with “filling up the treasure collection of the custodian for a certain Quadratum rooftop,” which aligns with Wall-E’s role as a custodian robot who collects and treasures discarded items.

There’s also mention of a world called the “Imagineer Planet.” While it doesn’t seem to connect to any obvious Disney lore, Walt Disney Imagineering is the research and development arm for Disney theme parks in real life. Interestingly, while achievements for other worlds require completing all requests, “Planet Producer” only asks players to finish any mission. This raises the question: could the challenges in Imagineer Planet be infinite or particularly tough, making it impractical to require completion of all tasks?

The full list of leaked games, along with their achievement lists, can be found on a gaming subreddit. This includes major titles that are still far off, like Judas and Persona 6, as well as those with confirmed release dates such as Metro 2039 and Final Fantasy Resonance, and even unannounced games based on existing IPs, like a potential Twin Peaks game and a Sea of Thieves sequel or spin-off.

Mike “x3sphere” Bendel, the owner of Exophase, shared on a forum that he believes this leak stems from a mistake at Valve: “It seems like a possible screw-up on Valve’s end, as a bunch of games with achievements that should be private are currently accessible through the API, which is why they got scanned into the site. I usually never see games without an actual name pop up with achievements, yet over the past hour or so, a bunch have (when there’s an unknown name, we just set it to the AppID).”
