Call of Duty: Modern Warfare II:n ja Call of Duty: Warzonen parissa työskennellyt säveltäjä Sarah Schachner on ilmoittanut, ettei enää työskentele Activisionin pyssyttelypelin parissa. Syyksi hän kertoo kasvavassa määrin haasteellisen kanssakäymisen äänipuolen ohjaajan kanssa.
"I am sad to say I can no longer continue to compose music for MWII / Warzone. Over the past couple of months the working dynamic with the audio director has become increasingly challenging and I don't see any path forward. As of now, I am unsure of the status and release plan for the soundtrack as it's been taken out of my hands."
"While I don't have any control over how the music is presented in-game, what will be released on the soundtrack is not my artistic intent in regards to mixing and mastering. Mike Dean was a part of the creative vision for the album as well as mixer Frank Wolf. We have soundtrack masters in hand from Mike which unfortunately you will never get to hear."
