Jeremy Dunham, the vice president for marketing and communications at Psyonix, couldn't specify which platforms they were exploring in comments to Gamezone. However, he explained that the game's launch on PC and PlayStation 4 — where it has been offered free to PlayStation Plus subscribers — but not Xbox One was not due to any agreement with Sony.
"The number one reason we're only on PlayStation and PC is because the team is small," Dunham told Gamezone. No more than a dozen people were working on Rocket League for most of its development and only recently has Psyonix brought in two more people.
Dunham said building for PS4 and PC was akin to building for "a platform and a half" thanks to the development toolkit for PlayStation 4, making it easier to build for both.
As for Xbox One, Dunham didn't specifically mention it but didn't rule anything out. "We will never say never to any of the platforms that are current gen," he told GameZone.
Rocket League is the sequel to Supersonic Acrobatic Rocket-Powered Battle Cars, a lesser-known title that launched in 2008 on Playstation 3. The current game has reviewed very favorably (Polygon scored it a 9). For more on Rocket League, check out our overview video below.
