The Kingdom Hearts crossover was widely expected to land in Fortnite’s v42.10 update on September 3, 2026. It did not. The Rocket League half of the event is now fully decrypted and visible in the files, while the Fortnite side sits unfinished, which points to a late change of plan rather than a leak that was wrong all along.
Quick answer: The collab missed v42.10 and is now expected in the following major update, v42.20, tracked for around September 17. Epic Games has not confirmed any Kingdom Hearts release date, so treat that window as unconfirmed until the content appears in the Item Shop.
Why the Kingdom Hearts collab looks delayed, not cancelled
The signal that made everyone expect a September 3 drop was a change in how the Kingdom Hearts car cosmetics were flagged in the backend. They were marked as cross-game, which is the state Epic’s shared vehicle items reach shortly before they go live in both Fortnite and Rocket League.
After the update went out, the picture split in two. The Rocket League event assets were decrypted in full, which means the version that was prepared for launch is now readable. The matching Fortnite files are incomplete, so the battle royale side was not in a shippable state when the update deployed. No reason for the hold has been given by anyone involved.
Late collab shifts are not unusual for Fortnite. Crossover content has been pulled from an update at short notice before, with the finished assets simply moving to the next patch window. The presence of complete, decrypted Rocket League items is the strongest indicator that the work exists and is waiting rather than being scrapped.
What is in the Gummi Ship bundle
The centerpiece is the Gummi Ship, the vessel used to travel between worlds in Kingdom Hearts, built as a driveable car body. Rendered images of the decal showed real textures from the series, including Sora’s outfit colors mapped onto an Octane.
The Rocket League package around it is a complete item set rather than a single vehicle.
| Item type | Quantity and details |
|---|---|
| Vehicle | Gummi Ship car body |
| Decals | Three, including one Octane-specific and one Universal |
| Wheels | Three sets |
| Boost and trail | One of each |
| Goal explosion | One |
| Profile items | Avatar border, player banner, topper |
| Crates | Free Gummi Crates |
Because these details come from game files and not an announcement, the final contents, pricing, and availability can still change before the set goes on sale.
Will the Gummi Ship car work in Fortnite Battle Royale?
Earlier datamines described the Gummi Ship as configured to function as a vehicle cosmetic in Fortnite as well as Rocket League, and the cross-game flag supports that. There is also a competing read that the ship body itself ends up limited to Rocket League, with Fortnite getting the decal treatment instead. Nothing in the files settles that split yet.
One thing that is not in doubt is what a vehicle cosmetic does. It changes the appearance of an existing car and leaves handling, health, and collision untouched. A Kingdom Hearts wrap will not alter how a vehicle drives in a match.
The car is also the easier half technically. A decal maps onto vehicle meshes that already exist, while a character outfit needs rigging, level-of-detail passes, and compatibility with pickaxes and back blings. That gap is one reason the vehicle content is further along than anything involving Sora.
Sora skin and Kingdom Key status
Epic has not confirmed a Sora outfit. What it has confirmed is the weapon. When Chapter 7 Season 4 launched on August 20, the developer stated that more items and outfits would arrive later in the season, naming the Kingdom Key from Kingdom Hearts among them. Sora also appears in the season’s promotional art, which makes an outfit likely without making it official.
The Keyblade has been described as arriving alongside the rest of the collab in the next update, potentially reworked from the Typhoon Blade’s behavior. That specific detail is unconfirmed and should be treated as a rumor until patch notes exist.

When the collab could arrive and how to confirm it
The next major patch in the sequence is v42.20, tracked for around September 17. No official date has been given for either the update or the Kingdom Hearts content, and Epic has published nothing about the crossover in its news feed beyond the Kingdom Key mention.
Two things can slip independently. Cosmetics regularly enter the files during a major update but stay out of the Item Shop for a week or more afterward, so a patch that adds Sora is not automatically the day you can buy him. The Rocket League items and the Fortnite items can also go on sale at different times, even though the two games usually align on crossovers.
You will know the collab has actually landed when the items are purchasable rather than merely present. Check the Fortnite Item Shop for a Kingdom Hearts section, check the Rocket League item shop for the Gummi Ship bundle, and look for the Kingdom Key in the update’s official patch notes. Datamined screenshots circulating ahead of that do not mean the content is buyable.
Note: Kingdom Hearts is one of several franchises still queued for Override, with Persona 5, Mega Man, and Pac-Man also waiting on Item Shop dates. A delay to one collab does not indicate anything about the others.
Until Epic says otherwise, the safe read is that the Gummi Ship set is finished and parked, the Kingdom Key is officially on the season’s roadmap, and Sora remains unconfirmed as a playable outfit. If the content does not appear in v42.20 either, that would be the first real sign the hold is longer than a single patch cycle.
