PlayStation 5 Cross-Platform Arma Reforger Server Setup Guide

PlayStation 5 support brings a massive new player base to Arma Reforger servers. This comprehensive guide covers everything you need to know to configure cross-platform servers that work seamlessly with both PC and PS5 players.

Understanding Cross-Platform in Arma Reforger

Cross-platform play allows PC and PlayStation 5 players to join the same Arma Reforger servers. However, enabling this feature requires specific configuration and comes with certain limitations.

Key Differences Between PC and PS5

PlayStation 5 Limitations:

• Mod restrictions: Not all PC mods work on PS5
• Platform-specific IDs: PS5 uses Xbox Live network layer
• BattlEye requirements: Must be enabled for cross-platform
• Performance differences: PS5 has hardware-specific constraints

PC Advantages:

• Full mod support from Workshop
• Higher graphical settings possible
• More configuration flexibility
• Easier server administration

Step 1: Enable Cross-Platform in Config.json

The simplest way to enable cross-platform is through your config.json:

Method 1: Enable All Platforms (Recommended)

{
  "bindPort": 2001,
  "publicPort": 2001,
  "game": {
    "name": "My Cross-Platform Server",
    "crossPlatform": true,
    "scenarioId": "{ECC61978EDCC2B5A}Missions/23_Campaign.conf",
    "maxPlayers": 32,
    "visible": true
  }
}

Setting crossPlatform: true automatically allows:

• ✅ PC players (Steam)
• ✅ PlayStation 5 players (PSN)
• ✅ Future console platforms

Method 2: Specify Platforms Explicitly

For more control, specify exactly which platforms can connect:

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

Available Platform Values:

• PLATFORM_PC - Steam PC players
• PLATFORM_XBL - Xbox/PlayStation network (used for PS5)

Step 2: BattlEye Anti-Cheat Configuration

CRITICAL: BattlEye MUST be enabled for cross-platform servers. PlayStation Network requires anti-cheat protection.

{
  "game": {
    "gameProperties": {
      "battlEye": true
    }
  }
}

Why BattlEye is Required

PlayStation 5 servers must use BattlEye because:

1. Sony policy: PSN requires anti-cheat for multiplayer
2. Security: Prevents cheating across platforms
3. Fair play: Levels the playing field between PC and console

Warning: Disabling BattlEye will prevent PS5 players from connecting!

Step 3: Mod Compatibility for PS5

The biggest challenge with cross-platform servers is mod compatibility. Not all PC mods work on PlayStation 5.

Checking Mod Compatibility

When adding mods, check the Workshop page for:

• ✅ "Console Compatible" tag
• ✅ "Cross-Platform" in description
• ✅ "PS5 Support" mentioned by author

Compatible Mod Example:

{
  "game": {
    "mods": [
      {
        "modId": "CONSOLE_COMPATIBLE_MOD_ID",
        "name": "Cross-Platform Weapons Mod"
      }
    ]
  }
}

Common Incompatible Mod Types

❌ Won't Work on PS5:

• Complex script mods
• Custom UI overhauls
• Third-party launchers
• Mods using external DLLs
• Very large content packs (>500MB)

✅ Usually Work on PS5:

• Simple gameplay tweaks
• New weapons/vehicles
• Map additions
• Sound replacements
• Small balance adjustments

Common Cross-Platform Issues

Issue 1: PS5 Players Can't Find Server

Symptoms:

• Server not visible in PS5 browser
• "No servers found" error
• Server shows for PC but not PS5

Solutions:

1. Verify crossPlatform: true or PLATFORM_XBL in supportedPlatforms
2. Enable BattlEye (battlEye: true)
3. Check server is set to visible: true
4. Ensure no PS5-incompatible mods loaded
5. Restart server after config changes

Issue 2: PS5 Players Disconnect Immediately

Symptoms:

• PS5 players connect but kick instantly
• "Connection timeout" error
• Works for PC, fails for PS5

Solutions:

1. Check BattlEye: Must be enabled
2. Remove incompatible mods: Test with vanilla first
3. Verify network: Open ports, check firewall
4. Update server: Ensure latest Arma Reforger version

Best Practices for Cross-Platform Servers

1. Start Vanilla, Add Gradually

Recommended Approach:

• Week 1: Vanilla server (no mods)
• Week 2: Add 1-2 confirmed compatible mods
• Week 3: Add 2-3 more mods if no issues
• Week 4: Finalize mod list (max 10 mods)

2. Test with Real PS5 Players

• Recruit PS5 beta testers from Discord
• Test during off-peak hours first
• Get feedback on performance and bugs
• Document any issues specific to PS5

3. Communicate Platform Support

In Server Name:

{
  "game": {
    "name": "[PS5] My Server | Cross-Platform Welcome"
  }
}
