In a perfect world, every multiplayer game would offer online play. But if you’re an indie developer with limited resources, sometimes adding proper netcode support just isn’t feasible, which is what Steam’s upcoming “Remote Play Together” intends to address.
Scheduled to go live as part of a beta test on October 21st, Steam’s new online multiplayer support is an extension of its current Remote Play feature that allows you to stream games from your home PC to other devices over the internet or a local wi-fi network.
According to Valve product designer Alden Kroll on Twitter, the way Remote Play Together works is that Steam streams the host player’s screen to other participating players while capturing controller or keyboard and mouse inputs from other players, before sending that info back to the host machine. This way, even games that were originally designed as local multiplayer or couch co-op titles can function online without any additional software or patches (though you will need to account for added latency due to streaming).
That means thanks to Steam’s Remote Play Together feature, fantastic local-only games like TowerFall Ascension, Samurai Gunn, or the original Nidhogg could get a new lease on life, as you’ll no longer be required to have everyone in the same room or use third-party apps like Parsec to get the full multiplayer experience.
However, Kroll also mentioned that Remote Play Together was designed primarily for shared-screen or split-screen games like the ones mentioned above, so depending on the specific title, some games may be better suited to Steam’s new online multiplayer feature than others.
