How does Remote Play Together work?

[Chaosolous]

What do I need to play games with my friend?

Just to host the game, then ask them to join?

Someone told me that I need to have two controllers plugged in on my device if I'm hosting, otherwise the other player can't play.

It doesn't detect the non-host controller? Someone explain it to me like I'm dumb. I have some games that have this feature available, I've never heard of it. I wanna play some games with some buddies but IDK what I need to do or what they need to have.

remote play together works for shared/split screen games

the host pc plays and streams the game video/audio to friends client pc, and their controls back to the game

for controller games, you will need one controller, the client should show up as the 2nd controller using steam input

but k/m input is always shared

for remote play together, steam will only stream the game window when it has focus, and only allow remote input to the game, not windows or desktop

Well currently it doesn't work at all...

Remote Play is down for all platforms. Windows, Linux, Steam Deck, and more. Affecting all games.

Steam support has not acknowledged the issue after nearly 3 days. You can find more info here:

There is a work around however until Steam Support wakes up:
- Update your client to the "Beta" version.
- Update your friend's client to the "Beta" version.

This works because the Beta version doesn't have the same invalid SSL certificate.

Please also open a Steam Support ticket! This will hopefully help them realise there is a global issue.
