Rocket League®

Soccer meets driving once again in the long-awaited, physics-based sequel to the beloved arena classic, Supersonic Acrobatic Rocket-Powered Battle-Cars!

A futuristic Sports-Action game, Rocket League®, equips players with booster-rigged vehicles that can be crashed into balls for incredible goals or epic saves across multiple, highly-detailed arenas. Using an advanced physics system to simulate realistic interactions, Rocket League® relies on mass and momentum to give players a complete sense of intuitive control in this unbelievable, high-octane re-imagining of association football.

Awesome features include:
 

All-new Season Mode that allows players to enjoy a full single-player experience
Extensive Battle-Car customizations with more than 10 billion possible combinations
Unlockable items and vehicles, stat tracking, leaderboards, and more
Addictive 8-player online action with a variety of different team sizes and configurations
Amazing 2-, 3-, and 4-player splitscreen mode that can be played locally or taken online against other splitscreen players
Broadcast-quality replays that allow you to fast forward, rewind, or view the action from anywhere in the arena
Competitive cross-platform gameplay with PlayStation®4, Xbox One, and Nintendo Switch users

Mac system requirements are as follows:
 

OS: MacOS X 10.8.5
Processor: Intel Core i5 2.4 GHz
Memory: 8 GB RAM
Graphics: OpenGL 4.1 - ATI Radeon HD 5670, NVIDIA GeForce GT 640M, Intel HD Graphics 4000 or Iris Pro Graphics
