IW engine

The IW engine is a game engine developed by Infinity Ward, Treyarch, and Sledgehammer Games for the Call of Duty series. The engine uses id Tech 3 as its core, since the engine itself is proprietary with inclusion of GtkRadiant by id Software. It has been used by Infinity Ward, Treyarch, Raven Software, and Sledgehammer Games.

History

The engine has been distinct from the id Tech 3 engine on which it is based since Call of Duty 2 in 2005. The engine's name was not publicized until IGN was told at the E3 2009 by the studio that Call of Duty: Modern Warfare 2 would run on the "IW 4.0 engine". Development of the engine and the Call of Duty games has resulted in inclusion of advanced graphical features while maintaining an average of 60 frames per second.

Call of Duty 4: Modern Warfare was released using version 3.0 of the engine. This game included features such as bullet penetration, improved AI, lighting engine upgrades, particle system enhancements and many more improvements. Treyarch began using an enhanced version of the IW 3.0 engine for Call of Duty: World at War. Improvements were made to the physics model and dismemberment was added. Environments also featured more destructibility and could be set alight using the flamethrower. The flamethrower featured propagating fire and it was able to burn skin and clothes realistically. Treyarch modified the engine for their James Bond title, 007: Quantum of Solace.

Call of Duty

Call of Duty is a first-person shooter video game franchise. The series began on Microsoft Windows, and later expanded to consoles and handhelds. Several spin-off games have been released. The earlier games in the series are set primarily in World War II, including Call of Duty, Call of Duty 2, and Call of Duty 3. Beginning with Call of Duty 4: Modern Warfare, which is set in modern times, the series has shifted focus away from World War II. Modern Warfare, released November 2007, was followed by World at War and Modern Warfare 2. Black Ops, released November 2010, takes place in the Cold War, while Modern Warfare 3, released November 2011, takes place in a near-future setting. Black Ops II, released November 2012, takes place mainly in the year 2025. Call of Duty: Ghosts was released in November 2013. In May 2014, Advanced Warfare was announced. On April 9, 2015, Treyarch announced Black Ops III.

The Call of Duty games are published and owned by Activision. While Infinity Ward is still a developer, Treyarch and Sledgehammer Games also develop several of the titles with the release of the studios' games alternating with each other. Some games have been developed by Gray Matter Interactive, Nokia, Exakt Entertainment, Spark Unlimited, Amaze Entertainment, n-Space, Aspyr, Rebellion Developments, Ideaworks Game Studio, and nStigate Games. The games use a variety of engines, including the id Tech 3, the Treyarch NGL, and the IW engine.

Engine

An engine or motor is a machine designed to convert one form of energy into mechanical energy.Heat engines, including internal combustion engines and external combustion engines (such as steam engines), burn a fuel to create heat, which then creates a force. Electric motors convert electrical energy into mechanical motion; pneumatic motors use compressed air and others—such as clockwork motors in wind-up toys—use elastic energy. In biological systems, molecular motors, like myosins in muscles, use chemical energy to create forces and eventually motion.

Terminology

The word "engine" derives from Old French engin, from the Latin ingenium–the root of the word ingenious. Pre-industrial weapons of war, such as catapults, trebuchets and battering rams, were called "siege engines", and knowledge of how to construct them was often treated as a military secret. The word "gin", as in "cotton gin", is short for "engine". Most mechanical devices invented during the industrial revolution were described as engines—the steam engine being a notable example.

Black operation

A black operation or black op is a covert operation by a government, a government agency, or a military organization. This can include activities by private companies or groups. Key features of a black operation are that it is secret and it is not attributable to the organization carrying it out. The main difference between a black operation and one that is merely secret is that a black operation involves a significant degree of deception, to conceal who is behind it or to make it appear that some other entity is responsible ("false flag" operations).

A single such activity may be called a "black bag operation"; that term is primarily used for covert or clandestine surreptitious entries into structures to obtain information for human intelligence operations. Such operations are known to have been carried out by the FBI, the Central Intelligence Agency,Mossad, MI6, ISI (Pakistan), RAW, MSS, and the intelligence services of other nations.

Etymology

"Black" may be used as a generic term for any government activity that is hidden or secret. For example, some activities by military and intel agencies are funded by a classified "black budget," of which the details, and sometimes even the total, are hidden from the public and from most congressional oversight.
