T4 (World at War) — Multiplayer

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 (Multiplayer) in the Plutonium Launcher

  1. Open the Plutonium Launcher and click “T4 Multiplayer” 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 Multiplayer from the launcher.

Notes

  • To reselect the folder later, click “Game Settings” next to the Play button.
  • Make sure you choose the actual World at War directory—not a parent “Games” folder or Documents.
