Rocket League is a physics-based vehicle soccer video game developed and published by Psyonix, released digitally for Microsoft Windows and PlayStation 4 platforms on July 7, 2015.

A retail version for PlayStation 4 and Xbox One will be distributed by 505 Games in June 2016.
Described as "soccer, but with rocket-powered cars", Rocket League has up to eight players assigned to one of two teams, using rocket-engine equipped vehicles to push a ball into their opponent's goal and score points over the course of a timed match. The game includes single-player and multiplayer modes which can be played both locally and online, including cross-platform play between the PlayStation 4 and Microsoft Windows versions as well as cross-play between Xbox One and Windows versions with the potential for other networks to be included in the future, The PC version of Rocket League features Cross-platform play with both the Sony PlayStation 4 and Microsoft Xbox One versions while the two consoles can't play with each other Cross-Platform yet. Later updates for the game enabled the ability to modify core rules and enabling new modes, such as gametypes based on ice hockey and basketball.
Rocket League is a sequel to Psyonix's Supersonic Acrobatic Rocket-Powered Battle-Cars, released in 2008 for the PlayStation 3, itself an idea based on the Onslaught game mode introduced in Unreal Tournament 2004. Battle-Cars received average reviews and was not a major success, but gained a dedicated fan base. Psyonix continued to support themselves through contract development work for other studios while looking to develop a Battle-Cars sequel. Psyonix began formal development of Rocket League around 2013, refining the gameplay from Battle-Cars to address criticism and fan input. Psyonix also recognized their lack of marketing from Battle-Cars, and engaged in both social media and promotions, including offering the title as a free download for PlayStation Plus members on release, to market the game.
Rocket League has been critically praised, earning a number of industry awards, and saw more than four million sales and at least 12 million unique players by early 2016. Rocket League has also been adopted as an eSport, with professional players participating through the Electronic Sports League and Major League Gaming, along with Psyonix's own Rocket League Championship Series.
