    Playing with several keyboards and mice? Press End once everything is in place to give each window its own cursor.

  4. Launch and connect

    Press Launch: Nucleus opens one copy of Call of Duty 4: Modern Warfare per player and lays the windows out on your screen. Then link them in game, usually one player hosts a LAN or online session and the others join it. The handler notes say how.

What you need

  • A Windows 10 or 11 PC

    Nucleus Co-op runs on Windows only. System requirements

  • Call of Duty 4: Modern Warfare for Windows

    Installed on that PC. Nucleus starts every player's window from that one install.

  • Nucleus Co-op, free

    With .NET Framework 4.7.2 or later and the Visual C++ 2015–2022 runtimes (x86 and x64). Download

  • Something to play with

    One keyboard and mouse per player. Controllers · Keyboards and mice

  • A PC that can run 32 copies

    Each player runs their own copy of Call of Duty 4: Modern Warfare, so the PC carries several times the usual load. Lower the graphics settings if it struggles. Performance tips

  • A multiplayer mode

    Nucleus links the windows through the game's own LAN or online mode; the handler takes care of it.

Handler notes

This handler works with the legit Steam Version and COD4X version. You can also get the latest patches and client version 21_1 from this link if you are using the CODX4 mod. You also need to have a valid CD-KEY already to join online servers.

For best performance fully close Steam before using the handler. The game doesn't have controller support so this handler only supports keyboards & mice.

This handler includes a Bots mod and autoit exe files for shortcuts (make sure you make an exception to the handler folder in your Antivirus as to not remove or block any files of the handler).

If you want to launch your custom mod just put it in the Mods folder inside the handler folder and write its folder name in the custom mod Nucleus UI option, the mod will launch automatically when you enter the game.

Start a match with the host player and there are 2 ways to make a client players to connect :

  1. Press '~' in your keyboard and type 127.0.0.1 local direct ip in the console and connect to the server normally.

  2. When you are in the main menu click join game and choose Favorites or Lan then you can see the host server appear, click on it and connect normally.

Big Thanks to messenils for his contribution with the handler.

About Call of Duty 4: Modern Warfare

Call of Duty 4: Modern Warfare differs from previous installments of the Call of Duty series. Previous Call of Duty games have a distinct three country-specific campaign style, while Call of Duty 4 has a more film-like plot with interlaced story lines from the perspectives of Sgt. Paul Jackson of the Marines 1st Force Recon and Sgt. 'Soap' MacTavish of the British 22nd SAS Regiment.
