Last June, Nintendo announced during E3 2017 that Rocket League is heading to Nintendo Switch. The announcement trailer also teased that exclusive items will be available for the Switch version. Developer Psyonix has now revealed more information about the exclusive goodies.

Rocket League on Switch will include Nintendo-themed Battle-Cars at launch: the "Mario NSR" and "Luigi NSR" Battle-Cars, which are obviously based on Mario and Luigi, and the "Samus' Gunship" Battle-Car, which is patterned after Samus Aran's gunship from the Metroid series.

The design of both the Mario NSR and Luigi NSR Battle-Cars look identical, with only the colors and the logo on the hood separating the two. The Battle-Car that players can use depends on which team they are on. The Orange Team has access to Mario NSR, while the Blue Team can drive the Luigi NSR.

The Metroid-themed Battle-Car also comes in two variants, which depends on team affiliation. The Samus' Gunship Battle-Car is available to Orange Team members, while Blue Team members get to drive in a "classic Samus color variation of her Varia Suit," according to Psyonix.

In addition, the "Super Star" Rocket Boost will be available for both Mario NSR and Luigi NSR, with the "Wave Beam" Rocket Boost an exclusive item for Samus' Gunship. As teased in the E3 2017 trailer, players can also use Mario and Luigi hats as decoration.

All the Nintendo-themed Battle-Cars are available for free at launch. However, players will need to complete certain requirements first in order to access the exclusive vehicles. Psyonix promised to share more details on the requirements in the future.

Rocket League on Switch is scheduled to arrive later this year. It will feature local multiplayer, as well as cross-platform online multiplayer between Switch, Xbox One, and PC users. Sony opted to stay away from the cross-platform multiplayer party, which elicited negative reactions from players.

Originally released in 2015 for PC and PS4, Rocket League is a game where players play soccer but with rocket-powered vehicles instead of actual athletes. You can think of it as a weird cross between FIFA and Destruction Derby. The game is currently one of the most popular multiplayer games around with 25 million registered players as of January 2017.
