Call of Duty Series Collection
Call of Duty is Activision's flagship first-person shooter franchise, spanning over two decades of war-themed combat across the trenches of World War II, the front lines of modern conflict, and the shadow wars of the Cold War era. Since the original game released in 2003, the series has built its reputation on cinematic campaigns, tight team-based gunplay, and multiplayer modes that have shaped competitive shooters for a generation of players.
The franchise is generally organized into a few core sub-series, each with its own tone and setting. The World War II series, including Call of Duty, Call of Duty 2, World at War, WWII, and Vanguard, focuses on the large-scale conflicts of the 1940s, following soldiers across the European and Pacific theaters. The Modern Warfare series shifted the franchise toward contemporary combat, starting with Call of Duty 4: Modern Warfare in 2007 and continuing through the acclaimed Modern Warfare 2 and 3, before the series rebooted the story entirely in 2019 with a new Modern Warfare trilogy. The Black Ops series, spanning Black Ops through Black Ops 7, has told its own separate story across Cold War proxy conflicts, near-future warfare, and covert operations, becoming one of the most consistently popular sub-series in the franchise.
Beyond these three pillars, Call of Duty has also pushed into more speculative territory with Advanced Warfare and Infinite Warfare, both set in near-future and space-based conflicts, while Call of Duty: Ghosts stands as a standalone entry unconnected to any of the other sub-series. Across nearly every release, the series has paired its single-player campaigns with deep multiplayer systems, and more recent entries have continued to expand class-based loadouts, large-scale maps, and cooperative Zombies modes that have become a franchise staple in their own right.

Call of Duty Games FAQs
Most Call of Duty games tell standalone stories, so there's no single required order. If you want to follow a specific sub-series, playing within that series in release order gives the clearest sense of story progression, for example the Black Ops games or the Modern Warfare reboot trilogy. Jumping between sub-series in any order won't affect your understanding of any individual game's campaign.
The original Modern Warfare trilogy, released between 2007 and 2011, follows one continuous story across three games. The 2019 reboot restarts the Modern Warfare name with new characters and a new continuity, continuing through Modern Warfare II and Modern Warfare III. The two are not connected, despite sharing the same title.
This depends on your preferred setting. Players interested in historical WWII combat should start with the WWII series, particularly Call of Duty: WWII or Vanguard. Players who prefer modern or near-future combat tend to gravitate toward the Modern Warfare or Black Ops series, both of which have large, well-regarded entries to start with.
This depends on the specific key. Region details are listed clearly on each product page, so be sure to check the activation region before purchasing to confirm it works in your country.
