1. LAN Multiplayer (with VPN like Hamachi or Radmin VPN)

You can simulate a local network with friends using VPN software:

What You Need:

• Hamachi (or Radmin VPN)
  
  

• A copy of Rag Doll Kung Fu on Steam (or DRM-free if available)
  
  

• Friends with the same setup
  
  

Steps:

1. Install Hamachi and create a private network.
   
   

2. Ask your friends to join your Hamachi network.
   
   

3. Launch Rag Doll Kung Fu and go to Multiplayer > LAN.
   
   

4. Host a game and have your friends join via the LAN option (they’ll connect through the VPN as if they were on your local network).
   
   

2. Port Forwarding for Direct IP Play

If you want to host over the internet without VPN:

Steps:

1. Find your local IP address (e.g., 192.168.x.x) and your external IP (via sites like whatismyip.com).
   
   

2. Open your router settings and forward the ports used by Rag Doll Kung Fu. Unfortunately, exact ports aren’t documented, but typical ports include:
   
   

   • UDP: 2300-2400
     
     

   • TCP: 47624
     
     

3. Have your friends connect using your external IP and the correct port.
   
   

4. Launch the game and host under Multiplayer > Direct IP.
   
   

3. Use Compatibility Fixes

Sometimes the multiplayer options don’t appear or crash due to compatibility issues with modern systems:

• Right-click the executable > Properties > Compatibility.
  
  

• Set to Windows XP (Service Pack 2) or Windows 7 mode.
  
  

• Run the game as Administrator.
