Arma Reforger Crossplay Config Guide

Crossplay requires four config fields to be set correctly — one wrong value silently breaks console connections. Select your target platforms below and get a ready-to-paste config.json block with all warnings surfaced before they become problems.

Target Platforms

PC is always included. Select any additional platforms you want to support.

config.json Block

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

Paste this inside the "game": {} object in your server config.json. The full file must also include bindAddress, port, and other required fields.

Field Reference

Field	Type	Notes
crossPlatform	bool	Must be `true` to allow cross-platform connections. Setting this alone is not enough — all four fields must align.
supportedPlatforms	string[]	Array of platform identifiers. Valid values: `PLATFORM_PC`, `PLATFORM_XBL`, `PLATFORM_PSN`. PC must always be included.
battlEye	bool	Platform policy mandates BattlEye when any console platform is listed. Console players receive no error — they simply cannot join if this is `false`.
mods (Workshop)	object[]	Each mod in the `mods` array must support the console platforms listed in `supportedPlatforms`. PC-only mods will cause console clients to disconnect at load.
