Psyonix

Psyonix is an American video game development studio based in San Diego, California, best known for creating Rocket League. Its work combines physics-driven vehicle gameplay, arcade sports and online multiplayer systems. The studio develops original games and has contributed engineering, gameplay and multiplayer development to releases made with other developers.

Founded in 2000 by Dave Hagewood, Psyonix emerged from his internet multimedia software business, WebSite Machines. Its early work focused on experimental multiplayer concepts and engine modifications. A collaboration with Epic Games led to the studio developing the Onslaught vehicle combat mode for Unreal Tournament 2004, establishing a relationship that continued through later projects and eventually ownership.

From vehicle combat to vehicular soccer

Psyonix released Supersonic Acrobatic Rocket-Powered Battle-Cars for PlayStation 3 in 2008. That game's combination of vehicles, physics and soccer provided the foundation for Rocket League, released in July 2015. The sequel brought the concept to a much larger audience across PC and consoles and became the studio's defining franchise.

Following its acquisition by Epic Games in 2019, Psyonix continued developing the franchise through ongoing content and online services. Rocket League moved to a free-to-play model in 2020, followed by the mobile game Rocket League Sideswipe in 2021. The studio also developed Rocket Racing, an arcade racing experience introduced within Fortnite in 2023.

Development capabilities

The studio's capabilities span full-cycle game development, vehicle physics prototyping, gameplay programming, Unreal Engine integration and technical art. Its multiplayer work includes backend architecture, networking, matchmaking and continuous live-service delivery. Community events, seasonal content and the Rocket League Championship Series also form part of its operational scope.

Alongside its original games, Psyonix has supplied co-development and technical contributions to projects including Gears of War, Bulletstorm, Mass Effect 3 and XCOM: Enemy Unknown. This history connects its original vehicle-based games with a broader background in multiplayer engineering and collaborative development.
