Rocket League developer Psyonix says that adding cross-platform multiplayer support between the Xbox One and PlayStation 4 versions of the popular eSports game could be added in "a few hours". All that stands in its way is approval from Sony's end.
In a chat with IGN, Psyonix vice president Jeremy Dunham stated:
"Right now. we're literally at the point where all we need is the go-ahead on the Sony side and we can, in less than a business day, turn it on and have it up and working no problem. It'd literally take a few hours to propagate throughout the whole world, so really we're just waiting on the permission to do so."
Rocket League already supports cross-play between the Xbox One and PC versions. In March, Microsoft announced that Rocket League would be the first Xbox One title with tools that allows any game on the console to support cross-platform multiplayer on other networks, including those on the PlayStation Network. So far, Sony has yet to approve any PlayStation game to allow for cross-play to the Xbox One, although there are a few that have PC support.
