Rocket League Coming to Nintendo Switch with Mario NSR, Luigi NSR and Samus Gunship Vehicles
Rocket League is coming to Nintendo Switch this Holiday season, with exclusive ‘Mario NSR,’ ‘Luigi NSR,’ and the ‘Samus’ Gunship’ as free unlockable Battle-Cars at launch. Along with the new vehicles, Rocket League on Nintendo Switch will have exclusive customization items.
Along with the new Battle-Cars, Rocket League on Switch will also have several exclusive customization items. The ‘Mario’ and ‘Luigi’ Toppers (hats) can be used on any non-licensed customizable Battle-Car, while the ‘Super Star’ Rocket Boost can be used with the ‘Mario NSR’ and ‘Luigi NSR’ cars. Likewise, the ‘Wave Beam’ Rocket Boost is exclusive to ‘Samus’ Gunship.’

Also, I thought RL for the Switch came with the Mario and Luigi cars? Is this something that's extra you have to pay for? Thanks for any help you can pass my way.

To play offline, you can start a season and it will be just ai or an exhibition match. I'm not sure if they changed the menus for switch though.
The game comes with the game but you need to unlock them. I'm not sure what the requirements are, though.
