Psyonix has shown another look at Rocket League running on Unreal Engine 6, this time focusing on professional players actively testing the rebuilt version of the game. The footage was shown during the final day of the 2026 Rocket League Championship Series World Championship, with players including GarrettG and JSTN participating in hands-on sessions and giving feedback directly to the development team. Psyonix says the process will continue as it refines the next version of Rocket League ahead of its expected 2027 transition.
The video presents the Unreal Engine 6 project as substantially more than a visual upgrade. Professional players are shown testing builds while Psyonix staff observe sessions and record feedback, with the studio describing the work as rebuilding Rocket League from the ground up. Psyonix also says these players will continue helping refine and improve the project over the coming months rather than treating the current playtest as a one-off event.
That involvement matters particularly for Rocket League because small changes to physics, input behavior or vehicle handling can have major competitive consequences. The game has accumulated more than a decade of player muscle memory, especially at the professional level, so reproducing its existing feel on a completely new technical foundation is likely to be one of the most sensitive parts of the transition. Bringing experienced competitors into the process gives Psyonix a direct way to compare the new build against expectations established by the current game.
Rocket League currently runs on technology dating back to Unreal Engine 3, despite the game launching in 2015 after Unreal Engine 4 had already become available. Psyonix formally revealed in May that the next era of Rocket League would instead be built around Unreal Engine 6, skipping the long-anticipated Unreal Engine 5 migration entirely. Epic later provided additional information about UE6 in June, describing it as a platform intended to combine traditional high-end game development with technology developed through Fortnite and Epic’s broader ecosystem.
The migration is increasingly tied to Rocket League’s plans for 2027. Separate reporting this month has suggested the 2027 RLCS calendar may include a mid-season pause while the game transitions to the new engine, although Psyonix has not publicly provided an exact launch date for the UE6 version. What is now clear from the latest footage is that a playable build exists and is far enough along for experienced professional competitors to evaluate it directly.
The engine work is happening while Psyonix continues updating the existing version of Rocket League. Season 24 introduces Honor Duels, Black Market Trade-Ins and new competitive features on September 23, showing that the current game remains in active development while the replacement technology is being built in parallel. That makes the UE6 project less like an ordinary engine patch and more like a long-running reconstruction happening alongside the live service.
Epic’s wider plans also give the migration additional context. A recently leaked Fortnite interface placed Rocket League alongside Fortnite, Disney, LEGO and Creative collaborations in a broader Universe Selector concept, while Epic has described Unreal Engine 6 as technology designed to support content across conventional games, Fortnite and interconnected ecosystems. Psyonix has not said that the new Rocket League will become a Fortnite mode, however, and the current playtesting footage continues to present it as Rocket League itself.
The biggest unanswered question remains how closely the new version will reproduce the mechanics of the existing game. Competitive Rocket League depends on extremely consistent physics interactions involving cars, the ball, walls and aerial movement, leaving little room for unnoticed differences between engines. The decision to involve professional players early suggests Psyonix is treating that consistency as a central development problem rather than assuming the new build can simply replicate the old one automatically.
Psyonix has not yet announced a precise 2027 release date, platform rollout plan or transition process for existing players and inventories. For now, the latest footage provides the clearest indication yet that the Unreal Engine 6 version has moved beyond announcement-stage development and into sustained hands-on testing, with the players most sensitive to mechanical differences helping shape how Rocket League’s next technical era will feel.
