Deep Dish Dungeon Crossplay: Steam, Xbox and Game Pass

Which versions talk to each other

Four entry points share one dungeon pool. Steam on Windows or macOS, Xbox Series X|S consoles, the Xbox app on PC, and Xbox Cloud Gaming can all join the same session, in groups of up to three.

The publisher's launch FAQ answers the question directly — "Crossplay is available across different platforms" — and the same FAQ restates the player cap, which is where the four-player confusion usually starts. There is no PlayStation or Switch version, and the FAQ's wording on that is careful: the team is working to support other platforms, but none is confirmed.

The technical confirmation

Marketing copy saying "crossplay" is worth less than an engineer saying how it was built. The Unity case study on Behold Studios states that the game runs crossplay between Steam and Xbox with no extra networking code, which is a much stronger claim than a store tag.

The same case study describes the architecture: peer-to-peer with no dedicated server, where the player who creates the world is the host. When a friend joins a session in progress, they have to catch up on every networked object — which enemies are dead, their remaining hit points, which items have already been picked up.

That detail explains the failure mode everyone eventually meets. There is no server holding the world together; the host's machine is the world.

What does not travel

Saves. If you buy on Xbox, the store lists Xbox Play Anywhere with cloud saves, which moves your progress between Xbox consoles and the Xbox app on PC. It does not move that progress to a Steam copy, and the publisher has not said it does.

Practically: pick the platform your friends are on and stay there, or accept starting a second world.

Getting a session to connect

The game is P2P, so most connection problems are network path problems rather than server outages. The checklist that resolves the majority, in order:

• Turn off your VPN. In one documented case, two players on Windows 11 failed every fix until the one using a VPN changed provider — a single case, not a rule, but a strong hint.
• Check the firewall for the game on both ends, not just the host.
• Simplify the network. Custom subnets and double NAT break peer connections more often than they break anything else.
• Swap hosts. Whoever has the cleaner connection should create the world.
• Update everyone. A version mismatch produces its own error string and looks like a connection failure.

Three symptoms are worth separating, because they have different answers: "Could not connect" is usually a path problem; "joined but frozen at the initial spawn" and "failed to deserialize server response" are reported without a known fix.

What a session actually looks like

Someone creates a world, names it, optionally sets a password of at least eight characters, and becomes the host. Friends take an invite or find the lobby in the browser, and a player can drop into a session that is already in progress.

There is no server in the middle. The host's machine holds the world state, which is why the session ends when the host leaves and why the host's connection decides everyone else's evening.

That answers "who should host" as well: the person with the most stable connection and the longest evening. A host who quits at ten takes the dungeon with them.

The invite flow is the least documented part of the whole feature. Crossplay is confirmed at the publisher and the engine level; which screen generates an invite that reaches a player on the other storefront is not described in either store listing.

Game Pass is not a separate platform

A Game Pass player is an Xbox-ecosystem player, whether they launch on a console, through the Xbox app on PC or by cloud streaming. The FAQ does not treat the subscription as a different platform, and nothing in the store listings suggests it is one.

That matters for group planning. A friend on PC Game Pass can join a Steam host, and a console player on Game Pass can join the same world from a sofa. What none of them can do is carry a Steam save across with them.

What patches actually fixed

Two of the ugliest co-op bugs are gone as of patch 1.0.50.0, and it is worth updating before you debug anything.

• Loading into a world with zero HP, no controls and an empty inventory after many players had joined.
• Duplicated lobbies in the lobby UI.
• A guest's arrows failing to register hits and damage.
• Hosts gained the ability to kick players from the pause menu.

Patch 1.0.47.0 had already fixed lobby passwords not taking effect when removed, which had made private worlds quietly public.

Which platform should you buy on

Buy where your group already plays, because the save file decides everything else. A Steam world and an Xbox world are two separate dungeons, and a weekend spent building one does not move.

If the group is split, Steam is the more flexible side: it covers Windows and macOS, and a Mac player has no Xbox option at all. The Xbox side is the better value only when Game Pass is already paid for, since the game is included rather than discounted.

Cloud Gaming is the wildcard. It runs the Xbox build, which means it joins Xbox sessions and shares Xbox saves, and it needs a stable connection rather than a capable machine.

Quick answers

Is Deep Dish Dungeon crossplay?

Yes. Steam, Xbox Series X|S, Xbox on PC and Xbox Cloud Gaming all share sessions, up to three players.

Do saves transfer between Steam and Xbox?

No. Xbox Play Anywhere and cloud saves work inside the Xbox ecosystem; a Steam save stays on Steam.

Does Game Pass count as Xbox for crossplay?

Yes. Game Pass is an entry point into the Xbox ecosystem, and the FAQ does not exclude it.

Is there a PS5 or Switch version?

No. The publisher says it is working on other platforms but has confirmed none.
