It seems Psyonix's recent aquisition by Epic Games is already paying off. Rocket League's aptly named 'Radical Summer' event features appearances from famous '80s franchises such as: Ghostbusters, Knight Rider, Back to the Future, E.T., and the Karate Kid.
Two new DLC packs will also be released during the event. The first is a Ghostbusters themed pack which includes the icon Ghostbusters Ecto-1 car and some other goodies like banners and avatar borders. This should be available on June 10th at the start of the event. The second cosmetic DLC pack, a Knight Rider themed bundle, will be released later and features the talking car K.I.T.T.
The event is split into 3 phases beginning on June 10th at 19:00 CET (17:00 UTC).
- '80s Blockbusters: June 10 - July 1
- '80s Culture: July 1 - July 22
- '80s Television July 22 - August 12
Two other game modes, Spike Rush Mode and Beach Ball Mode, are also planned for the later phases of the event.
