PC Game Pass vs Steam Crossplay: Why Some Games Fail & Which Ones Work (2026)
One of the most frustrating experiences in PC gaming today happens when you download a co-op game on PC Game Pass to play with a friend who owns the exact same game on Steam — only to discover that the two versions cannot see or join each other.
Just because two people are running Windows 11 does not mean their games share multiplayer servers. Multiplayer networking is governed by backend SDKs (Steamworks vs Xbox Live), not your operating system.
Why PC Game Pass and Steam Versions Split
When developers publish a game on Steam, they typically integrate Steamworks for friend lists, invites, voice chat, and peer-to-peer lobby discovery. This costs the developer zero extra server overhead because Valve handles the multiplayer routing.
However, when Microsoft adds that same game to Xbox Game Pass for PC, the Windows Store build requires the Xbox Live SDK for achievements, cloud saves, and party invites. Unless the studio creates a unified third-party backend (like Epic Online Services, a custom server cluster, or dedicated account system), the two builds remain completely isolated islands.
The Infamous Example: Deep Rock Galactic
Deep Rock Galactic is the poster child for store isolation:
- Steam players can ONLY play with other Steam players.
- PC Game Pass players can crossplay with Xbox Series X|S console players via Xbox Live.
- PlayStation players are completely locked in their own PlayStation Network pool.
If one friend has PC Game Pass and the other buys DRG on Steam, they cannot mine Hoxxes IV together unless one rebuy the game on the other's storefront.

How to Tell Before Downloading or Buying
- Look for an external publisher account prompt: Games requiring an EA Account (Battlefield), Ubisoft Connect, Epic Account (Remnant 2), or Capcom ID almost always support cross-storefront multiplayer because matchmaking runs on their private servers rather than Steamworks or Xbox Live.
