The Birth of Call of Duty: World War II Roots (2003–2006)

Early Days of Realism and Grit

The original Call of Duty (2003) was a direct competitor to Medal of Honor, aiming to deliver a more immersive and realistic depiction of World War II. It introduced:

• Squad-based AI instead of a “lone hero” model

• Real historical battles and locations

• Authentic weaponry like the M1 Garand and MP40

It was praised for its intense atmosphere and cinematic flair, setting a new bar for WWII shooters.

Expanding the Formula

The next two titles—Call of Duty 2 (2005) and Call of Duty 3 (2006)—further refined the experience with:

• Console-first development (especially for Xbox 360 and PS3)

• Enhanced AI and destructible environments

• Expanding multiplayer support

These games laid the foundation for the series' future blockbuster status.

Modern Warfare Revolution: A New Era Begins (2007–2009)

Call of Duty 4: The Game-Changer

In 2007, Call of Duty 4: Modern Warfare catapulted the franchise into the mainstream with:

• A modern combat setting for the first time

• Killstreaks, custom loadouts, and Perks

• A gripping single-player campaign featuring missions like “All Ghillied Up”

Its multiplayer mode became a cultural phenomenon, introducing millions to online FPS gaming.

Modern Warfare 2 and 3

• MW2 (2009) expanded multiplayer with customizable killstreaks, prestige, and larger maps

• MW3 (2011) concluded the trilogy with high-stakes cinematic set pieces and Spec Ops co-op mode

This trilogy redefined online shooters and created the first true esport-ready console FPS.

Black Ops and Cold War Espionage (2010–2015)

Psychological Warfare and Zombies

Treyarch launched its iconic Black Ops (2010) series with:

• A Cold War-era campaign full of mind-bending twists

• Popularization of the Zombies mode, turning co-op PvE into a full sub-franchise

• A high-skill, competitive multiplayer meta

Black Ops II (2012) went futuristic with branching campaigns, drone warfare, and a deeper eSports focus.

Diversifying Mechanics

Subsequent titles like:

• Black Ops III (2015) introduced wall-running and specialist characters

• Advanced Warfare (2014) and Infinite Warfare (2016) embraced jetpacks and sci-fi themes

These entries divided the community but demonstrated Activision’s willingness to experiment with new gameplay directions.

Return to Boots-on-the-Ground (2017–2019)

Community Fatigue with Futurism

After several jetpack-heavy entries, fans clamored for a return to realism. Activision answered with:

• Call of Duty: WWII (2017) — a visually stunning return to the series’ roots

• Black Ops 4 (2018) — the first CoD without a traditional campaign, focusing on Battle Royale (Blackout) and Zombies

Reinventing Modern Warfare

Call of Duty: Modern Warfare (2019), a reboot of the original, used the new IW engine and introduced:

• Realistic gun handling

• Dark, morally complex narrative

• Ground War (large-scale multiplayer)

This title revitalized the series and set the foundation for the current gameplay standard.

Warzone’s Impact

Released in March 2020, Call of Duty: Warzone became an instant hit with:

• 150-player lobbies
