Steam launches “Remote Play Together,” a feature that allows friends to join online games. With this update, only the host must own the game, while friends can participate.
You can join the beta here and launch local multiplayer games. After starting the game, go to your friend’s list and select “Remote Play Together.” Once your friends are linked, their controllers act as if they are plugged into your computer. You can then adjust the volume of the conversations and the audio game in one place.
Remote Play Together allows friends to play local multiplayer games online, stream their videos, audio files, inputs, and voices shared between placers. You can even share control of the keyboard and mouse. This is available on PC, Mac, and Linux.
