The remastered edition of Call of Duty 4: Modern Warfare, Call of Duty: Modern Warfare Remastered, may become available separately this summer. That can be deduced from store listings on several webshops.
The game is the remastered edition of Call of Duty 4: Modern Warfare that was released in 2007. The original title is still considered one of the best Call of Duty games of the franchise.
After the release of the game in 2007 many more titles followed, nine to be exact, that were all of lesser quality. Fans of the franchise consider recent Call of Duty games to be milking the succes of the original Modern Warfare title, claiming that newer titles bring no innovation or gameplay changes.
