The composer of Modern Warfare 2 has announced that he is ending his involvement with the film; in a statement posted on Twitter (opens in new tab), Sarah Schachner said that due to the "increasingly difficult" working dynamics with the audio director of MW2 and Warzone music and soundtrack releases, she said she could not continue to work on them and would wash her hands of the whole thing.

Shachner was also the composer for 2019's Call of Duty: Modern Warfare and Call of Duty: Infinite Warfare, but now says he "can no longer continue to compose for MW2/Warzone." Shachner said that her working relationship with the game's audio director has reached a low point in recent months and that she no longer sees a "way forward" for her work on MW2 and Warzone.

Disagreements over the release of the soundtrack appear to have been a major source of tension. The release of the soundtrack was worked out by Shakner, mixer Frank Wolf, and producer Mike Dean (who has worked with such luminaries as The Weeknd and FKA Twigs), but Shakner said that her preferred master of the soundtrack, "unfortunately you will never hear it," she writes. Instead, Shachner says, "What will be on the soundtrack is not my artistic intent regarding the mixing and mastering."

"I want to acknowledge the incredible hard work of the entire audio team," Shachner writes in his conclusion. But whether you enjoy it or not, Shachner is about to leave. She writes in her conclusion, "I feel a responsibility to my fans to remain authentic in my approach to the games and their sound that I have been involved in creating for so many years. [MW2 in particular, aside from its impenetrable UI (opens in new tab), is really good (opens in new tab), and its soundtrack and audio design play a big part in that. Nevertheless, with a resume that includes "Assassin's Creed" and "Call of Duty," it seems likely that we will be hearing Shachner's work in games again before too long.
