local co op in xcloud

Local co‑op on a single “virtual Xbox” is supported in the Xbox ecosystem, but behavior depends on how the game is being played.

For Xbox Remote Play (streaming from a home console):

• The game runs on the user’s own Xbox console.
• Players who are physically at the console can play together with the streaming player on the same console in local co‑op or versus modes, as long as the game itself supports local play and there are enough controllers.
• This is explicitly supported: “When playing a title via Xbox Remote Play, it's possible for users that are physically connected to the console to play with the streaming user.”

For Xbox Game Streaming / Xbox Cloud Gaming (game running on Xbox servers in Azure):

• The title runs on an Xbox server in an Azure datacenter and is streamed to the client device.
• The documentation describes that all Xbox games can be streamed and that local play (living‑room play) is a supported scenario on a single device, with multiple players and controllers, when multiple players are signed in on an Xbox One (or later) console.
• However, the provided documentation does not describe or guarantee support for connecting multiple controllers to a single cloud session in Xbox Cloud Gaming, nor does it describe any way to “map” two controllers to one profile in the cloud.

Regarding timing or roadmap (for example, when full local co‑op parity or specific 1v1 scenarios like Mortal Kombat 1 on cloud will be available), there is no information in the provided documentation. No dates or feature commitments are documented.

Regarding third‑party browser extensions such as “better xcloud”:

• The documentation provided does not mention or endorse any third‑party extensions or tools for modifying or extending Xbox Cloud Gaming behavior.
• There is no guidance here about their safety, legality, or support status.

For now, local co‑op is clearly supported when:

• Using Xbox Remote Play with players physically at the console, and
• Using local play on a single Xbox console with multiple signed‑in players and controllers.

Cloud‑only enhancements, controller‑to‑profile mapping changes, or third‑party extension usage are not covered or supported in the referenced material.
