CALL OF DUTY WWII Xbox One

The series originally focused on a World War II setting, with Infinity Ward developing Call of Duty (2003) and Call of Duty 2 (2005) and Treyarch developing Call of Duty 3 (2006). Infinity Ward's Call of Duty 4: Modern Warfare (2007) introduced a modern setting, and proved to be the breakthrough title for the series, creating the Modern Warfare sub-series; a Modern Warfare remastered version released in 2016. Two other entries, Modern Warfare 2 (2009) and Modern Warfare 3 (2011), were made. The sub-series received a reboot with Modern Warfare in 2019, Modern Warfare II in 2022, and Modern Warfare III in 2023. Infinity Ward have also developed two games outside of the Modern Warfare sub-series, Ghosts (2013) and Infinite Warfare (2016).

Treyarch made one last World War II-based game, World at War (2008), before releasing Black Ops (2010) and subsequently creating the Black Ops sub-series. Five more entries, Black Ops II (2012), Black Ops III (2015), Black Ops 4 (2018), Black Ops Cold War (2020), and Black Ops 6 (2024) were made, the latter two in conjunction with Raven Software. Sledgehammer Games, who were co-developers for Modern Warfare 3, have also developed three titles, Advanced Warfare (2014), Call of Duty: WWII (2017), and Vanguard (2021). They are also the lead developer for Modern Warfare III (2023), the third entry in the Modern Warfare reboot sub-series.
