SamLeakss reveals Kingdom Hearts “Gummi Ship” anthem in Rocket League files
Epic Games and Square Enix are reportedly preparing to bring the Kingdom Hearts franchise into Fortnite, following a significant update discovered in the backend of Rocket League. Data miners have identified the “Gummi Ship” theme from the original Kingdom Hearts as a new player anthem within Rocket League’s files.
This discovery is a strong indicator of an impending crossover, as Epic Games typically launches collaborative content across its major ecosystem titles simultaneously.
The update was shared by reliable Fortnite insider SamLeakss, who noted that the inclusion of the anthem suggests the collaboration is progressing. While the music track is present, the crossover appears to be in an unfinished state.
Only the anthem was found in the recent update, while a rumored “Gummi Ship” vehicle remains missing from the current files. Despite the incomplete set of assets, reports suggest the collaboration could arrive during Fortnite Chapter 7 Season 3, potentially following one or two more updates to the game.
Speculation surrounding this crossover has intensified following a new look at Kingdom Hearts 4 during a June 2026 Nintendo Direct. This showcase ended a four-year silence regarding the next mainline entry in the series.
Industry observers believe the Fortnite collaboration serves as a strategic marketing bridge, introducing the franchise to a younger generation of players while building momentum for the upcoming game. For fans, this news follows years of minimal updates from Square Enix regarding the series’ future.
Rocket League music leaks hint at Kingdom Hearts Fortnite arrival
The addition of the “Gummi Ship” theme to Rocket League is a technical precursor often seen before major Fortnite expansions. Because Epic Games frequently utilizes unified licensing agreements for its properties, music tracks and cosmetics often bridge the gap between the two titles. This development aligns with the massive $1.
5 billion partnership between Epic Games and Disney, the IP owner of Kingdom Hearts. This deal has accelerated the integration of iconic Disney-owned brands into what fans call the “Fortnite Metaverse.”
While the anthem is a concrete find, the full scope of the collaboration remains under wraps. Beyond the music, a “Gummi Ship” vehicle is also rumored to be in development, though it is currently unclear if it will be a drivable asset or a cosmetic item.
The strategy of using cross-promotional events to maintain interest in major gaming franchises is well-established. For instance, fighting game enthusiasts recently saw a similar move when Tekken 8 confirmed a Baki crossover to drive community engagement.
The release window for the Kingdom Hearts content is currently placed in “this season” or the coming months of 2026. This timeline would position the drop during a busy period for the gaming industry, similar to how other major developers schedule high-profile announcements.
Many are looking ahead to later in the year, particularly as Grand Theft Auto 6 is set for a late 2026 release, keeping the release calendar crowded through the end of the year.
Anticipated Sora skins and character outfits
Sora is expected to be the centerpiece of the collaboration, with leakers suggesting he will receive multiple styles. These potentially include his classic Kingdom Hearts 1 look and his more recent Kingdom Hearts 3 attire. Data miners like ShiinaBR and HYPEX have also mentioned “Limit Form” or “Anti-Form” as possible variants.
Other members of the trio, Riku and Kairi, are cited as strong candidates for their own character skins.
However, the inclusion of Disney’s core mascots, Donald Duck and Goofy, is considered less likely. Disney has historically been cautious about depicting these characters in contexts involving realistic combat, a policy that restricted their involvement in previous crossovers like Super Smash Bros. Ultimate.
Fans have also speculated about a potential Mickey Mouse skin, noting that the 1928 Steamboat Willie version of the character is now in the public domain.
Keyblades and LEGO Fortnite integration
The iconic Keyblade is heavily rumored to appear as a harvesting tool or “pickaxe.” The “Kingdom Key” is the most likely candidate for the primary skin, though leaks indicate other famous blades like “Oblivion” or “Oathkeeper” could be featured. There is even speculation regarding a Keyblade Mythic item, which would introduce unique gameplay mechanics to the Battle Royale mode for a limited time.
Furthermore, the characters are expected to receive LEGO variants for use in the LEGO Fortnite mode. This would ensure the collaboration reaches a broad demographic, from competitive shooters to creative builders. In a digital market where sales and digital events drive massive revenue, these multi-mode integrations are becoming the standard for high-profile intellectual properties.
As fans wait for an official announcement from Epic Games or Square Enix, the community is already debating the narrative implications of the crossover. Given the series’ lore involves traveling between “other worlds,” some wonder if Sora’s arrival on the island will be considered canon.
With a track record of reliable leaks from insiders like AdiraFNInfo, players are advised to keep an eye on social media channels for a formal trailer in the coming weeks.
