The original Supersonic Acrobatic Rocket-Powered Battle-Cars are coming to Rocket League later this summer as premium DLC.

Quote:

Available first as a timed exclusive in the Rocket League Collector’s Edition retail release, the jet-inspired Aftershock and monstrous Marauder will retain their original thematic style but also sport a new, more modern visual look. Both vehicles will also come with six gorgeous Decals immediately unlocked. See them in action for yourselves in our official trailer below! Look for both Aftershock and Marauder as part of the Rocket League Collector’s Edition on June 24 in Europe and July 5 in North America, followed by a worldwide digital release on July 18. Both cars can be purchased individually for $1.99 USD or regional equivalent.
