Those playing Rocket League on PC can now choose to play with and against those on Xbox One, and vice versa.

The soccer/racing mash-up is the second game to allow cross-network play between PC and Xbox One (the first was Killer Instinct), and other games are expected to follow suit.

Cross-network play between PC and PlayStation 4 has been possible in Rocket League since the game launched.

Adding the game’s pool of Xbox One players (or PC players, depending on your platform) to your match search is as easy as flicking a switch in the game’s options menu.

"Cross-network play has been something that Xbox One gamers have been asking us for since the day we launched, and thanks to Microsoft's new cross-network policies, we're proud to give it to them," said Psyonix VP Jeremy Dunham.

Earlier this year, Xbox suggested it was open to the prospect of cross-network play with PlayStation, but Sony was noncommittal.

"PlayStation has been supporting cross-platform play between PC on several software titles starting with Final Fantasy XI on PS2 and PC back in 2002," the company told Gamespot.

"We would be happy to have the conversation with any publishers or developers who are interested in cross-platform play."

PC is an open platform and so cross-network much more straightforward, added Sony Worldwide Studios' Shuhei Yoshida.

"Connecting two different closed networks is much more complicated so we have to work with developers and publishers to understand what it is they are trying to accomplish,” he said.

"We also have to look at the technical aspect - and the technical aspect could be the easiest. We also have to look at policy issues and business issues as well."

Note: An earlier version of this story stated that Rocket League was the first XO/PC cross-network game. We regret the error.
