Steam is preparing for the launch of a new "Remote Play Together" feature that allows you to play local multiplayer games with friends over the internet. "as if they were in the same room.Valve previously announced the new functionality via the Steamworks website PC Gamer reported its existence publicly. The new feature is scheduled for release in beta on October 21.
Remote Play Together has the potential to open local multiplayer games to a much wider audience, making them playable for anyone who has no people to play with in the neighborhood. Interesting, PC Gamer notes that the Steamworks page for the new feature says it works automatically for "all local multiplayer, local co-op and split-screen games," suggesting that developers don't have to do much to make their games compatible.
To clarify: it is really only for games with shared screen or with shared screen. The technology streams your screen to your friend and records their input and sends it back to the game, so you both play the same game and watch the same.

According to Alve Kroll from Valve, that confirmed the existence of the new function on Twitter, Remote Play Together works by streaming the screen from a host to a second player. Subsequently, the input from the second player is recorded and sent back to the game running on the host computer.
This is not the first time that we have seen a company try out such a function. Nvidia previously offered a cooperative function with a game streaming service called GameStream cooperativeand Sony offers similar functionality through the PS4's Share Play service. However, it is a challenging position. If one person plays a game locally while another has to stream it, the first player does not have to deal with the extra delay of streaming a game over the internet, which gives him a potentially huge advantage in competitive games .
