The Mario themed cars are actually just one new type of vehicle, and players who use it will alternate between the Mario and Luigi versions, depending on what team they are placed on.
Watch the Nintendo-exclusive Battle-Cars reveal trailer below.
Rocket League on the Nintendo Switch now has a holiday 2017 launch window, coming with local wireless multiplayer and cross-play capabilities between the PC and Xbox One versions of the game.
Both cars also have specialized boosts, called "Super Star" for the Mario and Luigi NSR and "Wave Beam" for Samus' Gunship.
Along with these comes a Metroid battle vehicle that is themed after Samus' gunship.
Psyonix made sure to state that all three cars will be available for free as special unlockables in the Nintendo Switch version of Rocket League. Boasting a community of more than 35 million players, Rocket League is a high-powered hybrid of arcade-style soccer and vehicular mayhem with easy-to-understand controls and fluid, physics-driven competition.
