Call of Duty is a highly successful video game franchise known for realistic depictions of combat, dramatic storylines, and a vast array of weapons. The series is a first-person shooter, a type of video game in which the action is seen from the perspective of the player, who is usually armed with a gun, a rifle, or other weapon. Originally set on the battlefields of World War II, the series has evolved to include modern and futuristic versions of combat. The series began as a game designed for a personal computer (PC) and later moved to home consoles and introduced multiplayer capabilities that allow players to compete with others online. The series also created the popular zombie mode, separate from the main storyline, in which the player can battle zombies or aliens in varying environments.

History

In 1999, video game company Electronic Arts (EA) developed Medal of Honor, a first-person shooter set in World War II. The game was a success for the PlayStation console and spawned a sequel the next year. While both games sold well, EA wanted to create a title for the PC, which was then seen as a more lucrative platform for that type of game. It hired game developer 2015 Inc. to make the next entry in the series, Medal of Honor: Allied Assault. The game introduced historic World War II battles into its storyline and was praised for its graphics and gameplay.

With the success of the game, many of the developers of Allied Assault wanted to step out of the shadow of the Medal of Honor series and create their own brand. A group of them left 2015 Inc. and formed a company called Infinity Ward. Infinity Ward signed with EA's rival, Activision, and in 2003 produced Call of Duty for the PC. The game is based on the Allied invasion of Normandy in 1944 and features cinematic cutscenes. It tells its mission-based story through multiple playable characters, elements that later became series trademarks. Call of Duty was a critical success, even if it posted modest sales figures.

While Activision made a number of spin-off titles for home consoles such as the PlayStation 2, GameCube, and Xbox, a true sequel to Call of Duty was released in 2005. Call of Duty 2 introduced a regenerating health system, which gradually heals characters. Call of Duty 2 was released on PC and for the Xbox 360, the console system from Microsoft. The game was the highest-selling title for the Xbox 360 upon its launch. To hold onto its market success and because it was not willing to wait the two years needed for Infinity Ward to produce another title, Activision hired developer Treyarch to create the next game in 2006. Call of Duty 3 was another shooter game set in World War II and was the first in the series to be released solely for home consoles.

The Call of Duty series took a different turn in 2007 when Call of Duty 4: Modern Warfare was released. For the first time, the franchise shifted its focus from World War II to the twenty-first century, building a storyline around a Russian ultranationalist bent on destroying the United States. The game is notable for introducing the perk system, which allows players to earn added abilities for their characters, and killstreaks, a system that rewards consecutive enemy kills. Modern Warfare was a huge success, with more than 15.7 million games sold worldwide. In 2008, Call of Duty: World at War took the series back to its World War II roots and was another popular title, also selling about 15.7 million copies. Call of Duty's zombie mode made its debut in World at War. The mode, which became a series staple, was separate from the main storyline and pitted the player against wave after wave of the undead.

Activision released a Call of Duty game every year since 2005, primarily alternating between developers Infinity Ward and Treyarch from 2005 to 2011, with additional support from other studios. Call of Duty: Modern Warfare 2 was released in 2009 and stirred controversy with a level in which the playable character is a double agent taking part in a terrorist attack on a Moscow airport. Players have the option of participating in the killing of innocent civilians or watching as they are gunned down. In 2010, Call of Duty: Black Ops was released. This game features a storyline involving a Special Forces agent and real-world events from the Cold War and Vietnam eras. When infighting at Activision resulted in a shakeup in Infinity Ward's management, the company created a new development team, Sledgehammer Games, to help with the next title. The result was 2011's Call of Duty: Modern Warfare 3, a continuation of the plotline of the previous installments. Modern Warfare 3 went on to sell more than 26.5 million copies, the most of any game in the series to that point. The next two titles in the series, Call of Duty: Black Ops 2 in 2012 and Call of Duty: Ghosts in 2013, continued the success of the franchise, boasting increasingly complex graphics and weapons. In 2014, Call of Duty: Advanced Warfare moved the series fifty years forward in time. It features futuristic weapons, armor, and battle tactics. Call of Duty: Black Ops 3 was released in November 2015 and posted $550 million in sales in its first three days of release.

The games released between 2016 and 2024 reflected shifting trends in gameplay and setting. Call of Duty: Infinite Warfare (2016) ventured into outer space, drawing criticism for its futuristic theme but still topping charts in the United States and the United Kingdom. In 2017, Call of Duty: WWII marked a return to historical roots and became the year’s best-selling console game in North America. Black Ops 4 followed in 2018, notably dropping a traditional single-player campaign in favor of battle royale and multiplayer modes. In 2019, Modern Warfare rebooted the iconic subseries with a gritty, realistic tone, followed by Black Ops Cold War (2020), Vanguard (2021), and Modern Warfare II (2022). Modern Warfare III launched in 2023, continuing the franchise’s focus on high-fidelity visuals, cross-platform integration, and evolving online play. In 2023, Microsoft acquired Activision Blizzard, bringing the Call of Duty franchise under Xbox ownership while maintaining cross-platform availability. Newer releases have also been integrated into subscription platforms such as Microsoft's Xbox Game Pass.

Call of Duty: Black Ops 6 debuted in October 2024 and was reported to be one of the biggest releases in the franchise's history. The game was reported to set records for day-one players and increases in subscription services such as Xbox Game Pass, along with the record for total number of players and hours played over the three-day opening weekend for any Call of Duty game. Black Ops 6 also bested Modern Warfare III for copies sold on PlayStation and Steam with a 60 percent increase year-over-year and pushed the franchise to over 500 million copies sold. Xbox Game Pass was restructured into multiple tiers in 2025 with higher subscription prices, and day-one releases such as Call of Duty were primarily tied to higher-tier plans.

In November 2025, Call of Duty: Black Ops 7 was released. While the game was a top bestseller globally, it did not sell as well as its predecessors and received poor reviews. Many fans were also unhappy with the presumed use of generative artificial intelligence (AI) in some of Black Ops 7's in-game art. Shortly after the game's release, Activision announced that Call of Duty titles like Black Ops and Modern Warfare would no longer receive sequels in consecutive years.

The Call of Duty: WWII storyline is rooted in historical realism, following a US infantry squad through major battles in the European theater of World War II, emphasizing camaraderie, sacrifice, and the brutality of war. In contrast, the Black Ops series takes a more conspiratorial and psychological approach, blending Cold War-era espionage with mind control, covert operations, and alternate histories across multiple decades. These story arcs differ from stand-alone titles like Infinite Warfare or Modern Warfare, which either explore futuristic warfare in outer space or modern-day geopolitical conflicts through more grounded, often morally ambiguous narratives. Each branch reflects a distinct tone—historical, paranoid thriller, or contemporary military drama—offering players varied narrative experiences within the franchise. However, traditionalists tend to prefer the WWII releases, as that was the initial draw of the franchise.

Success and Impact

Since 2003, the Call of Duty franchise and its spin-offs have sold over 500 million copies and earned more than $35 billion worldwide by 2025. The games have consistently been among the best-selling and best-reviewed games upon their yearly release. The franchise holds the Guinness World Record for best-selling first-person shooter video game series.

The Call of Duty series has made a cultural impact as well. It has forged product tie-ins with Mountain Dew and Doritos and utilizes the voice acting of several A-list Hollywood actors such as Michael Keaton, Scott Glenn, and two-time Academy Award winner Kevin Spacey.

Call of Duty has also paired up with the US Military to enhance recruitment, forming esports teams and engaging with gamers on platforms like Twitch to appeal to younger audiences. While effective in outreach, this approach has raised ethical concerns about glamorizing war and targeting impressionable players through the use of video games.
