The world of Call of Duty

What is Call of Duty?

Call of Duty, abbreviated to CoD, is one of the most influential and successful franchises in gaming history, shaping the first-person shooter genre for over two decades. Since its debut in 2003, the series has evolved from World War II settings to modern combat, futuristic warfare, and expansive online experiences. The impact of Call of Duty lies in its ability to deliver cinematic storytelling, fast-paced multiplayer gameplay, and constantly evolving mechanics that keep players engaged year after year.
The franchise is especially known for setting industry standards in online multiplayer, popularising features like progression systems, seasonal content, and large-scale battle royale modes such as Warzone. Its annual releases consistently attract millions of players worldwide, making CoD a cultural phenomenon beyond gaming.
Call of Duty remains innovative by adapting to new technologies and player expectations, refining gameplay systems, and integrating cross-platform play, ensuring it stays relevant in an ever-changing gaming landscape.

The many faces of a shooter

CoD is a broad franchise that includes multiple sub-series and gameplay styles, each offering a different experience while sharing the same core shooting mechanics. Among its most recognisable branches are Modern Warfare and Warzone, which represent two distinct directions within the series. Modern Warfare focuses on cinematic storytelling and traditional multiplayer modes, while Warzone expands the formula into a large-scale, free-to-play battle royale. Together, they highlight how Call of Duty evolves while staying connected under one identity.

Call of Duty: The main Call of Duty series acts as an umbrella covering all yearly releases, including different sub-franchises such as Modern Warfare and Black Ops. Each title typically features a single-player campaign, competitive multiplayer, and often a co-op mode. What defines CoD is its fast-paced gunplay, accessible mechanics, and constant innovation through new settings, technologies, and gameplay systems, making it one of the most recognisable names in gaming.
Modern Warfare: Modern Warfare is one of the sub-series within Call of Duty that focuses on contemporary military conflicts and grounded, realistic storytelling. Known for its cinematic campaigns and iconic characters, it blends tactical gameplay with intense action. The rebooted series, starting in 2019, modernised the formula with improved graphics, deeper weapon customisation, and tighter mechanics, while maintaining the traditional multiplayer modes fans expect from Call of Duty.
Black Ops: Black Ops is another sub-series centred on covert operations, espionage, and psychological themes, often set during the Cold War or in near-future scenarios. It stands out for its complex narratives, unexpected twists, and experimental gameplay elements. Black Ops also popularised the Zombies mode, a cooperative experience that has become a staple of the franchise and a fan favourite across multiple entries.
Warzone: Warzone is a free-to-play extension of Call of Duty that centres on large-scale battle royale gameplay. Instead of small matches, it drops dozens of players into a massive map where they compete to be the last squad standing. Warzone introduces mechanics like the Gulag for second chances and integrates weapons and progression from other Call of Duty titles. Warzone represents the franchise’s shift toward live-service gaming with regular updates and seasonal content.

Play the latest entries

The latest Call of Duty entries - Modern Warfare III (2023) and Black Ops 7 (2025) - show two different directions for the franchise. One builds on realism and continuity, while the other pushes experimentation and new ideas. Both aim to evolve the formula, but they do so in very different ways.

Call of Duty: Modern Warfare III (2023)
Modern Warfare III continues directly from Modern Warfare II, focusing on a grounded, modern conflict and the hunt for terrorist leader Vladimir Makarov. The campaign emphasises global stakes and tactical operations, following Task Force 141 as they try to prevent a large-scale war.
One of the biggest gameplay changes is the introduction of Open Combat Missions, which give players more freedom to approach objectives using stealth or direct action. This adds a semi-open structure compared to the traditionally linear campaigns. Multiplayer leans heavily on nostalgia, bringing back classic maps while reintroducing fan-favourite mechanics like the red dot minimap and slide-cancelling.
Another major addition is the open-world Zombies mode, where multiple squads explore a large map, complete objectives, and extract resources, blending traditional Zombies with Warzone-style gameplay. Overall, MWIII focuses on refining existing systems rather than radically changing them.

Call of Duty: Black Ops 7 (2025)
Black Ops 7 takes a more ambitious and experimental approach. Set in 2035, the story follows David Mason and a special operations team investigating a global conspiracy tied to the return of Raul Menendez. The narrative leans into psychological themes, advanced technology, and a more futuristic tone.
One of the biggest innovations is the co-op campaign, playable solo or with up to four players, something rarely seen in Call of Duty campaigns. The game also introduces a unified progression system, where actions in campaign, multiplayer, and Zombies all contribute to overall progression.
Gameplay improvements include Omnimovement, allowing more fluid and dynamic traversal, alongside expanded multiplayer content with large-scale maps and modes. The return of classic round-based Zombies, combined with new modes and features, reinforces the Black Ops identity while pushing it forward.
Overall, Black Ops 7 represents a more innovative step, experimenting with structure, progression, and cooperative storytelling, while still delivering the core Call of Duty experience.
