Host and guest responsibilities
The host needs an installed, working Steam game; the guest needs Steam on a supported device. Update Steam on both sides. Start the game locally once before streaming it, and confirm that both friends appear online.
This is appropriate when one computer will run the local match. In native online play, both players run the game and use its lobbies instead.
Invite, accept, then test inputs
- The host launches the game and opens the overlay with Shift + Tab.
- From the friends list, the host selects the friend’s Remote Play Together invitation option.
- The guest accepts. In the session controls, the host checks the permitted guest input devices.
- Set up a local two-player match. Test both fighters’ movement and actions before playing.
Keyboard input is shared with the host. Distinct game bindings still matter; a stream is not a second independent keyboard profile. Controllers can make the player assignments clearer. See shared keyboard setup for the game’s simultaneous-input limits.
If the invitation or guest input fails
Check that the host launched through Steam, the friend is online, the overlay is available and guest input is permitted. If the guest can see the game but cannot move, check session permissions and player bindings before recreating a native-online room code. Valve’s support route can diagnose repeated streaming failures.
