Steam Version: If you own it on Steam, ensure Multiplayer and Zombies are both installed.
Alternative: Some clients provide their own download methods (e.g., via a torrent or dedicated launcher). Step 2: Use an Offline Client/Launcher

LanLauncher: For a truly offline experience (playing without internet or account login), use the LanLauncher for T6.

Run the launcher and point it to your game installation directory. Select Multiplayer or Zombies and set a username.
Click Launch T6 to start the game without connecting to the internet. Step 3: Add Bots (Optional for Multiplayer) To make offline multiplayer engaging, you can add AI bots. Download the T6 Bot Warfare mod from GitHub.
Place the mod files into your game's scripts folder (typically AppData/Local/Plutonium/storage/t6/scripts or similar, depending on your setup).
Bots will now be available in custom games even when offline. Troubleshooting Common Issues
