There are two separate questions hiding inside is backrooms game cross platform: whether you can play together, and whether your progress follows you. They often have different answers.
The approach below has been checked against the current version rather than a patch from two years ago. People often blame the game when the actual cause is a setting they changed weeks ago. There is a fast way and a safe way, and they are not the same thing.
The short answer
Where crossplay exists, it usually needs a shared account linked on both platforms — that link is what people forget.
Who can play with whom
The approach below has been checked against the current version rather than a patch from two years ago. If something here stops matching what you see on screen, the game has probably changed a value in an update. Version mismatches after an update can split the player base for a day or two. Start with the simplest option before touching anything that is hard to reverse.
Most advice on this topic assumes you already know half the answer, which is exactly the problem. The community figured most of this out through repetition, and the pattern has held up well. Invites sometimes only work in one direction, which looks like a bug and is not.
Progress and purchases across platforms

- Back up your save if the game gives you the option.
- Check the version you are running before following any step-by-step advice.
- Write down what you changed, so you can undo it if the result gets worse.
- Keep a spare loadout for the attempts that go badly.
How to set it up
There is a fast way and a safe way, and they are not the same thing. Invites sometimes only work in one direction, which looks like a bug and is not. Buying on one platform rarely entitles you to the game on another. The approach below has been checked against the current version rather than a patch from two years ago.

Mistakes worth avoiding
- Following a guide written for an older version and assuming nothing moved.
- Trusting a video thumbnail over the actual patch notes.
- Skipping the preparation step because it looks boring, then repeating the hard part four times.

No. Everything described here works with the game as installed, which also means nothing breaks when the next patch lands.
Does this still work after the latest update?
