Requirements
- Plutonium Launcher installed and signed in. If needed: plutonium.exe
- Call of Duty: World at War (WaW) files installed on your PC.
Default Windows path (Steam):
C:\Program Files (x86)\Steam\steamapps\common\Call of Duty World At War
Set up T4 (Co-Op/Zombies) in the Plutonium Launcher
- Open the Plutonium Launcher and click “T4 Co‑Op/Zombies” in the left sidebar.
- Click the “Setup” button.
- When prompted, select your World at War game folder (see the default path above).
- Confirm the folder; the launcher will validate and prepare your files.
- Click “Play” to launch T4 Co‑Op/Zombies from the launcher.
Notes
- To reselect the folder later, click “Game Settings” next to the Play button.
- Make sure you point to the actual World at War directory—not a parent “Games” folder or Documents.
