The best way to play Call of Duty is on a PC with a good internet connection. You can also play on a console, but you will need an Xbox Live Gold or PlayStation Plus subscription to do so.

If you're playing on a PC, the first thing you need to do is make sure your system meets the minimum requirements for the game.

You can find these requirements on the Call of Duty website.

Once you have checked that your system meets the minimum requirements, you will need to purchase the game.

Call of Duty can be bought through Steam or other digital retailers such as Amazon.
