In this guide, we will provide you with friendly step-by-step instructions on how to troubleshoot and resolve the "MW3 Campaign Early Access Not Working" issue. Whether you are playing on a console or PC, these solutions will help you get back into the action and enjoy the game to its fullest.

How to Fix Modern Warfare 3 Campaign not working error


Section 1: Power-cycle your console or restart your PC


One of the first steps in troubleshooting any technical issue is to power-cycle your console or restart your PC. Power-cycling involves completely turning off your console or unplugging it from the power source and waiting for a few minutes before turning it back on. This process helps clear any temporary glitches or conflicts that may be causing the campaign not to work.


If you are playing on a PC, simply restarting your computer can have a similar effect. Restarting your PC clears the system's memory and closes any conflicting processes that may be interfering with the game.


To power-cycle your console, follow these steps:

  • 1. Turn off your console completely.
  • 2. Unplug the power cord from the console and the power outlet.
  • 3. Wait for at least 5 minutes to ensure all residual power is drained.
  • 4. Plug the power cord back into the console and the power outlet.
  • 5. Turn on your console and launch Modern Warfare 3.

To restart your PC, follow these steps:

Section 2: Ensure game download completion and wait for it to finish


If you are experiencing issues with the MW3 campaign not working, it is crucial to ensure that the game has downloaded completely. Modern games often have large file sizes and require significant download times.

To check the download progress on your console, follow these steps:

  • 1. Navigate to the game library on your console.
  • 2. Look for Modern Warfare 3 and highlight it.
  • 3. Check the download progress indicated on the screen.
  • 4. If the download is not complete, allow it to finish before launching the game.

On PC platforms like Steam, the download progress is usually displayed within the Steam client. Look for the game in your library and ensure that the download bar reaches 100% before attempting to launch the game.
