Additional Info: Inventory can be shared across platforms! Link your accounts to enable this feature. Purchased items can only be traded on the platform it was purchased. For example, if you build a Blueprint with Credits on Xbox, you can only trade it on Xbox. After linking accounts, other tradable items can be traded on any platform. You can only trade with other players logged into the same platform as you. While in a party you can use the Party Chat to text chat to your friends on all platforms. During a match, only Quick Chat can be seen by everyone. Only players on your platform can see typed in-game messages. On PC, pressing the U key can be used to Party Chat in-game. Cross-platform voice chat is currently not available. You may disable Cross-Platform Play in your Gameplay settings. It may take longer to find matches this way. It’s not possible to exclude specific platforms.
Summary:

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.
