If you’ve ever stayed up until 3 a.m. trying to prestige or screaming at a "no-scope" on Rust, you’ve probably wondered who actually birthed this monster. The short answer is a studio called Infinity Ward. But the real story? It’s basically a corporate thriller. It involves a "secret" office, a mass exodus from a rival company, and a pair of guys who ended up becoming the most influential (and controversial) names in gaming history.
Honestly, the "creator" of Call of Duty isn't just one person with a laptop. It was a group of about 22 people who basically staged a mutiny to make the game they wanted.
The 22 Rebels: Who Really Created Call of Duty?
Back in 2002, a small studio in Tulsa, Oklahoma, called 2015, Inc. released a game called Medal of Honor: Allied Assault. It was a massive hit. Steven Spielberg was involved. It was cinematic. It changed everything. But the guys making it were miserable. They felt the owner of 2015, Inc., Tom Kudirka, wasn't giving them the creative freedom or the paycheck they deserved.
So, they planned an escape.
Vince Zampella, Jason West, and Grant Collier were the ringleaders. While still working at 2015, Inc., they started secret talks with Activision. They wanted to start their own thing. They didn't just want to leave; they wanted to take the whole "dream team" with them. In what became a legendary move in the industry, nearly the entire core team of Allied Assault quit at once and formed Infinity Ward.

Activision gave them $1.5 million for a 30% stake in the company to build what they called the "MOH (Medal of Honor) Killer." That game was the original Call of Duty, released in 2003.
The Key Players
- Vince Zampella: The business mind and executive producer. He’s the guy who later went on to lead Respawn Entertainment (Apex Legends, Titanfall) and is now basically the king of shooters at EA.
- Jason West: The technical wizard and creative lead. He was the one obsessed with the "feel" of the gunplay.
- Zied Rieke: The lead designer who wrote a lot of the original game and helped define that "cinematic" feel where you weren't just a lone wolf, but part of a squad.
Why Call of Duty Was Different From the Start
Before Call of Duty, most shooters were "Rambo" simulators. You were one guy taking on the entire German army. Infinity Ward changed that. They introduced the idea of the "Big Red One" and squad-based AI. You felt like a cog in a giant war machine.
They used the id Tech 3 engine (the Quake III engine), but they hacked it to pieces to allow for hundreds of soldiers on screen. It was loud. It was chaotic. It was exactly what players wanted.
Activision was so impressed they bought the remaining 70% of Infinity Ward just a few days before the game even launched in October 2003. They knew they had a gold mine.

The Messy Divorce: Activision vs. The Creators
You can't talk about who created Call of Duty without talking about the 2010 scandal. It’s the most famous firing in tech history.
After Modern Warfare 2 became the biggest entertainment launch ever, things got ugly. Zampella and West wanted more control and huge bonuses. Activision, led by Bobby Kotick, allegedly didn't want to pay up. In March 2010, security guards literally marched Zampella and West out of the building. They were fired for "insubordination."
What happened next?
- The Lawsuit: A billion-dollar legal battle that dragged on for years.
- The Mass Exodus 2.0: Just like they did at 2015, Inc., dozens of employees quit Infinity Ward to follow West and Zampella to their new studio, Respawn Entertainment.
- The Trio of Studios: This is why we now have a rotating cycle of developers. Since Infinity Ward was gutted, Activision had to lean on Treyarch (who made Black Ops) and Sledgehammer Games to keep the yearly release schedule alive.
The Modern Era: Who Makes it Now?
Today, the "creator" is a massive machine. While Infinity Ward still exists, it's a completely different group of people than the 2003 team. The franchise is currently maintained by a "tripod" of lead studios:

- Infinity Ward: Still handles the Modern Warfare sub-brand.
- Treyarch: The masters of Black Ops and the Zombies mode.
- Sledgehammer Games: Often fills the gaps, like with Vanguard or WWII.
- Raven Software: The unsung heroes who basically run Warzone day-to-day.
Actionable Insights for Fans and Creators
If you're a gamer or an aspiring dev looking at this history, there are a few "real-world" takeaways from how this franchise was born:
- The "Feel" is Everything: Jason West’s obsession with how a gun kicks and the sound design is why CoD still feels "snappier" than Battlefield or Halo to most people. If you're building something, nail the core mechanic first.
- Talent Follows Talent: The fact that the same team moved from 2015, Inc. to Infinity Ward and then to Respawn shows that in the gaming world, people matter more than brands.
- IP is King: The 2010 lawsuit proved that even if you create the game, if you don't own the "Intellectual Property" (the name and the rights), the publisher holds all the cards.
Tragically, we lost one of the original fathers of the series recently. Vince Zampella passed away in late 2025 at the age of 55. His legacy is basically the entire modern FPS genre. From Medal of Honor to Call of Duty to Apex Legends, the way we point and click at things on a screen was largely defined by his vision.
Next time you're dropping into a map, remember it didn't come from a corporate boardroom. It came from a bunch of guys in Oklahoma who were tired of their boss and decided to take a huge gamble on a "Medal of Honor killer."
