Overview
Call of Duty (CoD) is a first-person shooter (FPS) game series developed by the American studio Infinity Ward and published by Activision in 2003. Beginning with the first installment set in World War II, it expanded its settings to modern warfare, near-future warfare, and space warfare, growing into one of the best-selling game franchises in the world.

Birth and Early Series
The 2003 first installment was created by Infinity Ward developers who came from the Medal of Honor series, and it was praised for squad-based combat presentation in which players fight alongside NPC comrades. Later, Call of Duty 4: Modern Warfare (2007) introduced a modern warfare setting and progressive multiplayer systems such as killstreaks, perks, and customization, leading the series to explode in popularity. Modern Warfare 2 (2009) achieved both controversy and commercial success, cementing the franchise's status.
Sub-Franchise Distinctions
- Modern Warfare: Modern and near-future terrorism subject matter, and the origin of representative characters such as Captain Price and Soap.
- Black Ops: Developed by Treyarch, differentiated by Cold War, conspiracy theory, and psychological warfare elements and the Zombies mode.
- World War II / Vanguard: A return to World War II.
- Infinite Warfare / Advanced Warfare: Enhanced mobility such as booster jumps and futuristic weapons.
Multiplayer and Additional Modes
The core axis of the series is multiplayer. 6v6-based fast engagements, weapon leveling and Gunsmith, and killcams became standardized. The cooperative Zombies mode (Black Ops line) and Special Ops, as well as the campaign, are famous for cinematic presentation and large-scale scope.
Warzone and Live Service
Call of Duty: Warzone, released in 2020, marked a turning point as a free-to-play battle royale. Combining a large battlefield for 150 players, the Gulag revival system, and regular seasonal updates, it became a sustained revenue model for the series. Afterwards, Warzone 2.0 and the mobile version Call of Duty: Mobile expanded the service.
Esports and Industry Impact
The Call of Duty League (CDL) operates as a franchise-based league and forms a pro scene centered on the United States and Europe. Its revenue structure through annual releases and season passes and battle passes is evaluated as a representative example of major game companies' live-service strategies.
Latest Trends
For the 2024–2025 series, after Microsoft's acquisition of Activision Blizzard (completed in 2023), integration with the Xbox Game Pass ecosystem is a key topic. Call of Duty: Black Ops 6 (2024) was included in Game Pass from its first day of release, beginning a subscription-based distribution experiment in earnest, and the omnimovement system spanning campaign, Zombies, and multiplayer was introduced, greatly changing engagement patterns. In addition, Warzone is operated with seasonal content and integrated progression (carryover), while cross-progression with the mobile version and anti-cheat (Ricochet) reinforcement continue. In 2025, along with expectations for the next numbered title, discussions about introducing operations automation technologies such as AI-based matchmaking and voice moderation are active.
