A massive SteamDB leak reportedly exposes Kingdom Hearts 4 achievements, worlds, gameplay systems, and potential secret boss encounters months early.
Kingdom Hearts 4 has endured one of the worst leaks in the franchise's history, with the entire list of achievements reportedly leaking on SteamDB. That leak is particularly fascinating given that the Square Enix game, which is incredibly hotly anticipated, has not yet been launched and its full promotional push seems to have barely started.
The leaked document reportedly includes the game's milestones for the game’s worlds, story progression, gameplay elements, and other activities. Most of the list seems to be in place; however, some of the achievement descriptions are not complete. This makes the leak a lot bigger than the typical achievement leaks that pop up right before a game is released.
The timing is all the more surprising. Usually you can see the list of achievements closer to the release date (sometimes only a few weeks or months before). In this case, the information has supposedly been leaked while Kingdom Hearts 4 is still in development. As such, the leak gives fans potentially significant information about the game ahead of when Square Enix and Disney decide to present it to the public.
A Kingdom Hearts 4 achievement leak could give us some big upcoming reveals for the game.
The worst part about the leak is that it’s purportedly showing all of the worlds in Kingdom Hearts 4. Achievement games do not mention Disney or franchise properties directly but are said to mirror the unique naming conventions associated with Kingdom Hearts settings. This means that the information might have to be interpreted, but evidently fans of the series are capable of figuring out what several of the names mean.
Thus, significant global announcements that would normally be saved for trailers and promotional events may already be online. This is especially troublesome considering very little information about the worlds of the game has been officially revealed so far. And the next marketing cycle would be slowly revealing new locations, features, characters, and systems through trailers and other releases.
This leak could therefore threaten one of the most exciting elements of the game’s commercial drive. Fans could learn about things like new planets months before Square Enix is ready to tell them, instead of finding out through official trailers. The list of achievements, according to reports, includes more than just world-famous names.

It also looks to be referencing certain systems and activities such as elements from special encounters and secret boss fights. There are other story-related achievements, but many of them have incomplete descriptions. Some story achievements reportedly use placeholder text rather than finalized descriptions.
The leaked achievement list is purported to show worlds and game elements months ahead of time.
But it seems the names are there; thus, it looks like the fundamental framework of the achievement list has been built already. The leak has been compared to the Kingdom Hearts 3 Monsters Inc. world leak of 2017. But the existing leak could be a lot larger, as it is said to contain data from all throughout the game and not just one area.
The intrusion reportedly affects a number of additional undisclosed or highly anticipated games. The same leak on SteamDB apparently listed games including Persona 6, Attack on Titan 3, Judas, Rayman Legends, Star Wars Galactic Rangers, Dragon Ball Xenoverse 3, and Stranger Than Heaven.
Where the information is from is probably connected to how SteamDB stores metadata provided by publishers and developers. When information is submitted to Steam, SteamDB can automatically save the metadata. That could be how the achievement data got leaked if Square Enix leaked the Kingdom Hearts 4 material early.
Which makes it all the more amazing that the information appears to have been leaked before the publisher was ready to make it public. The most major impact for fans is how long the leaked information could remain online. There is no official release date for Kingdom Hearts 4 at this time, so we might continue to see leaked material for months until the game really lands in stores.
Fans now have to sit through months of potential spoilers before Kingdom Hearts 4 is released.
Fans who want to enjoy the marketing campaign without major spoilers should be careful when browsing social media, forums, and gaming communities. World names and achievements may be posted in posts, pictures, videos, or chat without notice. With how much hype there is for the next major marketing push for Kingdom Hearts 4, the leak is doubly bad.
Instead, there is a significant amount of information at once in the achievement list. You can’t guess everything from just the name of an achievement, but the combination of world-related achievements and references to gameplay mechanics could provide fans far more information than Square Enix intended.

As the release date gets closer, official trailers will be released, revealing more of the game. Fans have been waiting for new information for years. Square Enix and Disney could have picked worse timing. The companies are now confronting the possibility that major reveals planned for the upcoming publicity drive have already been exposed on the internet.
Kingdom Hearts 4 has fallen victim to another big leak, just as promotion kicks off.
The event also comes amid a long history of leaks and surprising truths that have emerged in the series ahead of formal releases. Kingdom Hearts has always had problems with information leaks before it was supposed to, and this latest one is perhaps one of the biggest. If you don’t want to be spoiled, remain clear of Kingdom Hearts 4 content for now, especially if it mentions achievements, worlds, or leaks.
The stolen file supposedly contains enough information to spoil critical parts of the future adventure, making it significantly more important than an average gameplay leak. The information in the supposed accomplishment leak has not been officially released by Square Enix. The corporation has not provided any further information.
So fans should treat leaked content as unofficial and refrain from sharing specific spoilers. But the fact that we’re seeing a near-complete achievement list is a good hint that work is well underway behind the scenes. It’s unclear if this implies we’re reaching the end of the development cycle for Kingdom Hearts 4, but the leak has given fans an unexpected look at stuff that seemed to be behind closed doors for much longer.
