My first COD ever. Before playing it I didn't know that a video game could be like a movie. In your first mission you have to kill Castro, then they take you from Cuba to a rebellion in a Russian prison and then to Vietnam, total madness. And if the campaign wasn't enough, it had zombies mode and a hidden arcade game. The best COD of all time. It deserves to be on gog and if you haven't played it, you should do so right now.
