T4 (World at War) — Co‑Op/Zombies

Required: You must own Call of Duty: World at War on Steam. If your Steam account doesn’t own it, the client will not work.

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

  1. Open the Plutonium Launcher and click “T4 Co‑Op/Zombies” in the left sidebar.
  2. Click the “Setup” button.
  3. When prompted, select your World at War game folder (see the default path above).
  4. Confirm the folder; the launcher will validate and prepare your files.
  5. 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.
