The Game Engine is what controls many aspects of the game such as physics and graphics.

id Tech 3 Engine[]

The id Tech 3 Engine by Id Software is the first engine used by the series. Both the IW Engine and Treyarch NGL are based on it.

IW Engine[]

Original[]

The IW Engine was developed by Infinity Ward for Call of Duty 2 and was based on Id Tech 3. It's the game engine powering most of the Call of Duty series.

It is used by many games, including:

Revamped[]

A revamped version of the engine, named IW 8.0, was developed by Infinity Ward Poland and Infinity Ward LA with assistance from NVIDIA. Its development started five years before the release of Modern Warfare in 2019. In 2022, Infinity Ward released Call of Duty: Modern Warfare II with the updated engine IW 9.0.[1]

Sledgehammer Games Engine[]

Sledgehammer Games built a custom in house-engine for Call of Duty: Advanced Warfare[2] with little code from the MW3 Engine. An upgraded version was developed for Call of Duty: WWII. It is also used by Raven Software and Beenox for the two remasters of the Modern Warfare series.

Treyarch NGL[]

Treyarch developed an in-house engine named Treyarch NGL based on the Call of Duty: United Offensive version[3] of the Id Tech 3 engine. It was only used in two games before it was replaced by IW 3.0 for Call of Duty: World at War.

Asura Engine[]

The Asura Engine is the engine used by Rebellion Developments for their version of Call of Duty: World at War.

RenderWare[]

The RenderWare is a game engine developed by Criterion Games. It was chosen by Spark Unlimited for one Call of Duty game.

Unity Engine[]

Unity is a generic cross-platform game engine developed by Unity Technologies. So far it's only used for mobile Call of Duty games.

Trivia[]

  • The choice of RenderWare by Spark Unlimited made the development of Call of Duty: Finest Hour extremely difficult and caused the massive delay of the release date.[4]
    • During the development of the game, Criterion Games, the developer of the RenderWare engine, was acquired by Electronic Arts, one of the rival of Call of Duty's publisher, Activision.
