Call of Duty: Modern Warfare III is a 2024 first-person shooter video game developed by Sledgehammer Games and published by Activision. It is a sequel to 2024's Modern Warfare II, serving as the third entry in the rebooted Modern Warfare sub-series and the twentieth installment in the overall Call of Duty series.

Reportedly, Treyarch was set to develop CoD 2024 but Activision reshuffled their development plans, moving Sledgehammer Games onto an expansion of MW2, which panned out into its own full annual release as Modern Warfare 3. Therefore, Treyarch looks to be taking the lead on CoD 2024.
