Along with the bountiful free content that has been added to Rocket League occasionally developer Psyonix has offered up paid DLC as well. Four new vehicles have been added to the game today and are being sold for $2 each. The cars were previously only found in the Collector’s Edition of the game sold by retailers in physical form.
Now those who own Rocket League digitally can obtain them on PC, PS4, and Xbox One. Keep in mind all the cars in Rocket League essentially perform the same so it’s just a matter of deciding whether a cosmetic purchase is deemed worthwhile. The new cars are Masamune and Esper (Neo-Tokyo update themed) along with Marauder and Aftershock (classics from Supersonic Acrobatic Rocket-Powered Battle-Car).
