I've found interesting tutorial on how to install COD6 multiplayer and I want to share this with you. But there are few thing to be done before you start installing.
- Test your PC so you can run MW2,
- Install Torrent Client
- Install Microsoft .Net Framework 3.5
- Install Microsoft Visual C++ 2008 Redistributable
- Install WinRar
All these application you can easily find on Google. So there's no need for links here. After you install all of this download DLCs Repository Torrent and Bootstrap update.
- Extract the archive with your favourite archiver.
- Use alterIWNet_configure.exe to set your nickname.
- Run iw4mp.exe and wait for the latest updates to be fetched.
