According to Nintendo’s description of the game on its website, “Take to the pitch for a fully-featured offline season mode, multiple game types, casual and competitive online matches, and special “Mutators” that let you change the rules entirely. Express yourself with one of the deepest customization systems around and battle opponents on other platforms with groundbreaking cross-network play!”
The game is priced at $19.99 which is pretty reasonable, and will support as many as 1-8 players for online mode. It will also support up to 8 players in handheld mode, assuming you have enough controllers, although for TV mode it seems that the max players supported will be limited to 4.
Rocket League has been available for various platforms for a while, which includes the Xbox One, PS4, Windows, Mac, and now finally it has arrived on the Switch. The Switch version of the game will also include Mario, Luigi, and Samus Battle Cars.
