Arma Reforger Crossplay: One Server for PC, Xbox and PS5

Reforger supports three-way crossplay between PC, Xbox Series X|S and PS5 on a single server. Enabling it is one boolean. The parts worth reading about are the platform-restriction interaction with mods, and the fact that consoles cannot host.

Enabling it#

In the game block of config.json:

{
    "game": {
        "crossPlatform": true
    }
}

crossPlatform defaults to false. When it is true, the server accepts every platform and supportedPlatforms is ignored entirely.

Restart the server afterwards — platform settings are read at boot.

Restricting to specific platforms#

To run a single-platform server, turn crossplay off and name the platform:

{
    "game": {
        "crossPlatform": false,
        "supportedPlatforms": ["PLATFORM_PC"]
    }
}

Valid values are PLATFORM_PC, PLATFORM_XBL (Xbox) and PLATFORM_PSN (PlayStation).

The mods interaction#

This is the part that catches people out.

PlayStation Network certification restricts user-generated content. At Reforger's console launch that meant PS5 clients were excluded from modded servers outright. That has since loosened — PS5 can join modded servers — but it is not a blanket "mods work on PS5 now": certain mod types remain unavailable on the platform.

The practical consequence is that you cannot reason about it from documentation. If your group includes console players and you run mods:

1. Build the modlist you want.
2. Have an actual player on each console platform try to join.
3. Only then commit to it.

Test per platform rather than assuming one console result generalises to the other — the certification rules that drive this are platform-specific.

If your modlist turns out to be incompatible, the options are to trim it, or to run crossplay off for a narrower platform set and accept the exclusion. See mod collections — keeping a lighter console-safe collection alongside your full one is a reasonable way to run both.

Consoles cannot host#

Neither Xbox nor PS5 can run an Arma Reforger dedicated server. A console-hosted session exists only while that player is in it, with their connection and their hardware behind it.

For a console group that wants a persistent world — your own scenario, your own rules, available when you are not online — a rented server is the only route. That is covered in can you host on Xbox or PS5.

Finding the server from a console#

All three platforms use the same in-game server browser. There is no separate console list.

If console players cannot find a server that PC players can see:

• Check the platform filter in the browser. It excludes servers by platform support and is on by default in some client versions.
• Confirm crossPlatform is actually true on the running server, not just in a config file you edited but did not restart into.
• Search by name rather than scrolling. The list is long.
• Rule out the general causes in the server browser checklist — a version mismatch looks exactly like a platform problem from the client side.

Verify it worked#

1. config.json validates and crossPlatform is true. Use the config validator.
2. Server restarted after the change.
3. A PC client finds and joins it.
4. An Xbox client finds and joins it.
5. A PS5 client finds and joins it — and if you run mods, that the modded content is actually present for them rather than silently missing.

Test all three platforms you intend to support. Two out of three passing tells you nothing about the third, and PS5 is the one most likely to differ.
