Valve has announced that it will be adding a new feature to Steam, called Remote Play Together. This feature will allow local multiplayer and co-op games to work over the Internet. As such, PC gamers will be able to play with their friends online the games that were not supporting online play previous (but obviously had support for local MP play).

Hidden in Plain Sight’s developer received the following email from Valve, detailing this feature.

As the email suggests, all local co-op and split-screen games will automatically support Remote Play Together. This will be crucial for a number of games, so kudos to Valve for implementing it.

Lastly, the beta phase for Remote Play Together will launch on October 21st.
