After 15 years at Sledgehammer Games, Call of Duty multiplayer creative director Greg Reisdorf has departed. His contributions spanned numerous Call of Duty titles, beginning with Modern Warfare 3 (2011). Reisdorf played a pivotal role in the development of Modern Warfare 3's multiplayer, including its live seasonal content and modes.

Reisdorf's journey at Sledgehammer Games, which launched in 2009, encompassed key moments in Call of Duty history. His early work on Modern Warfare 3 included memorable sequences like Soap's gurney scene in "Blood Brothers." He also significantly impacted the "boots on the ground" era with his work on Advanced Warfare's movement systems (boost jumps, dodging, tactical reloads), weaponry, and map design. While he acknowledges some design choices, like Advanced Warfare's "Pick 13" system, weren't perfect, his contributions were undeniable.

His reflections on WW2 highlight the importance of player agency, noting the initial limitations of the "Divisions" system and the subsequent positive changes. His preference for classic three-lane map designs in Vanguard reflects his focus on engaging gameplay over strict military realism.

Reisdorf's final project, Modern Warfare 3 (2023), saw him oversee the multiplayer's live seasons, including innovative modes like Snowfight and Infectious Holiday. His involvement extended to over 20 modes throughout the game's post-launch support. His departure marks the end of a significant chapter, but his statement suggests continued involvement within the gaming industry.
