Back in October this year, Valve announced a beta version of Steam Remote Play Together that lets you play local multiplayer games over the internet. You will be able to play with your friends across the platform. It means you will be able to play irrespective of whether you are using Windows, Linux, or macOS based computers.
From today onwards, Remote Play Together will be officially available for everyone. You will be able to play with your friends irrespective of the platform whether you are using iOS and Android devices as well.
Valve elaborated on how two friends can play together. They said that at first, the host player must install and start the game, and after this only, his or her friends will be able to join on PC via Steam Remote Play or on mobile with the Steam Chat and Steam Link apps. This means only the host must own the game.
It should be noted that the reviewers are yet to test Remote Play Together with iOS and Android clients so nothing could be said regarding network latency, whether it is an issue or it is fine when you are playing an action-packed game.
In general, network latency depends on the host’s internet connection and how far away they live. In the promotional stream released by Valve, it looks pretty smooth.
