Rocket League is a high-powered hybrid of arcade-style soccer and vehicular mayhem with easy-to-understand controls and fluid, physics-driven competition. It's an indie racing game developed and published by Psyonix LLC in 2015. Rocket League includes casual and competitive Online Matches, a fully-featured offline Season Mode, special “Mutators” that let you change the rules entirely, hockey and basketball-inspired Extra Modes, and more than 500 trillion possible cosmetic customization combinations.
System requirements for desktop computers as stated by the developer. Updated on January 18, 2020.
The system requirements are modest, but it's recommended to have a dedicated graphics processing unit for successfully playing Rocket League. GeForce GTX 775M or better mobile GPU is needed.
The RAM requirement of 4gb is easily met, though 2gb is enough to meet the minimum requirements.
Also, note that at least 7gb of disk space is needed.
