Modern Warfare III continues one of the best-selling video game series of all time by hearkening back to a beloved earlier entry. The first Call of Duty: Modern Warfare 3 (note the Roman numerals in the 2023 iteration) was released in 2011 and was co-developed by Sledgehammer Games and Infinity Ward; both studios are collaborating once more on the new release. Following 2022’s Call of Duty: Modern Warfare II, Call of Duty: Modern Warfare III marks the first time the franchise has launched a direct sequel in back-to-back years.

„Walter is a veteran of film, television, and video game work alike, with a knack for the type of hybrid electronic and orchestral scoring that Call of Duty is known for.“

Call of Duty takes a darker turn with ‘Modern Warfare III’. The story offers unexpected twists and the music had to capture a wide range of emotions and also hit hard. Over the past months Walter has been recording soloists and the London Contemporary Orchestra at AIR Studios and treated the recordings with effects that reflect his style as a composer. The score makes use of expressive electronic sounds including some modular synth madness from his collection.

Behind the Score

In collaboration with the game director, audio director, music director and music producer of MW III, this video gives an in-depth look into the scoring process and the many elements involved to create the music for this thrilling title.

In creating the original score for Call of Duty: Modern Warfare III, Walter was tasked with balancing the franchise’s legacy with gameplay innovations and storytelling development. Walter fused electronic and traditional orchestral instruments, blurring organic and industrial musical styles for an emotional backdrop. Collaborating closely with the London Contemporary Orchestra at Air Studios (London), he experimented with unique sounds like strings played with guitar picks and brass instruments distorted through analog effects. He also worked closely with solo instrumentalists to enhance the score’s emotional depth. To ensure an immersive experience, Walter collaborated with Sledgehammer Games and Spider Farm Productions, creating an adaptive soundtrack that responded to players‘ styles and gameplay pace. This meticulous attention to detail and passion for innovation resulted in a gaming experience steeped in Call of Duty traditions and worthy of the Modern Warfare title.

„Games in the Call of Duty series have always boasted a musical score by a top-tier composer, with Hans Zimmer and Brian Tyler involved on previous entries. Screen Rant is excited to announce that the composer tapped for Call of Duty: Modern Warfare III is none other than Walter Mair, whose recent work includes the multilingual Apple TV+ thriller Liaison.“

„The initial concept was to record textures and patterns with the London Contemporary Orchestra, treat these through the modular synth rig, add a rich electronic soundscape and write strong themes on top that connect us with Captain Price, Makarov and Farah.“
