Fans are looking forward to a new book called Call of Duty. In addition to providing a release date for Call of Mission: Modern Warfare, which has not yet been finalized as a subtitle, Infinity Ward has also released a short video to build momentum. "Modern Warfare" has been an open secret for some time, so the news may not surprise some fans. To some extent, adding new works to the series is more an expectation than a desire. Call of Mission: Modern Warfare will be released at 2 a.m. Beijing time on May 31.
