Steam’s feature, Remote Play Together, which gives you access to stream local multiplayer games with friends over the internet, does not require every player to have a Steam account anymore. The gaming company’s new functionality which is currently in beta, lets Steam users invite a friend to their game with a link, after which they’ll need to download the Steam Link app.
Although the new feature still have limits. Games will need to already support the Remote Play Together feature for it to work, and only one friend without a Steam account can join a multiplayer session. If you wish to include more, they’ll need to have accounts.
If you want to access this feature, go to your friends list in the Stem overlay while playing a Remote Play Together-compatible title and click the “Copy Link” button. The game company says you’re able to send links to friends to play on windows, Android, iOS, or even Raspberry Pi devices.
