Infinity Ward is an American video game developer located in Woodland Hills, California. Established in 2002, Infinity Ward has developed Call of Duty 2, Call of Duty 4, Modern Warfare 2, Modern Warfare 3, Ghosts, Infinite Warfare, and Modern Warfare.


Infinity Ward was founded as an Activision division by Grant Collier, Jason West, and Vince Zampella in 2002. The studio was formed by several members of 2015 Games, LLC., the studio that developed the successful Medal of Honor: Allied Assault for Electronic Arts (EA) in 2002. Dissatisfied with the current contract they had under EA, Collier, West, and Zampella engaged with Activision to help establish Infinity Ward, which became one of the primary studios within Activision for the competing Call of Duty series. Initially, Activision provided Infinity Ward US$1.5 million for 30% stake in the company to start development on the first game Call of Duty, acquiring full ownership after the title was successfully launched in 2003. During this period, the studio was about 25 employees including many who followed Collier, West, and Zampella from 2015. Activision allowed Infinity Ward a great deal of freedom in how it developed its titles.[1]

Shortly after this release, Microsoft contacted Activision to seek a Call of Duty title as a launch title for the upcoming Xbox 360 console. Infinity Ward agreed to prepare Call of Duty 2 for release in the last quarter of 2005. Collier said the request would help them lose the stigma of being only a personal computer developer, and so to make sure the console version was on parity, they tripled their staff to about 75 employees. Much of the focus of Infinity Ward's development was improving its game engine to include realistic special effects, such as smoke grenades to hinder sight, or bullets piercing through weak materials. Call of Duty 2 was a major success, having an 85% attach rate to new Xbox 360 console sales, and selling 1.4 million units its first year. At this point, Activision brought in Treyarch, one of their internal studios, to help develop additional Call of Duty games, with Infinity Ward spending the time and effort to improve the game's engine for one game, and Treyarch using the updated engine to create a new title. Treyarch released the next sequel Call of Duty 3 while Infinity Ward itself developed Call of Duty 4: Modern Warfare, which instead of taking place during World War II, was set in a contemporary period with a fictional conflict between superpowers. At the time of Modern Warfare's release, Infinity Ward had more than 100 employees.[2]
