The BFG is a fictional weapon found in many video games, mostly in first-person shooter series such as Doom and Quake.

Enemy Territory: Quake Wars is a first-person shooter video game developed by Splash Damage and published by Activision for Microsoft Windows, Linux, Mac OS X, PlayStation 3 and Xbox 360.

It is the second multiplayer-focused game in the Quake series after Quake III Arena.

Fast inverse square root, sometimes referred to as Fast InvSqrt or by the hexadecimal constant 0x5F3759DF, is an algorithm that estimates 1⁄√x, the reciprocal of the square root of a 32-bit floating-point number x in IEEE 754 floating-point format. This operation is used in digital signal processing to normalize a vector, i.e., scale it to length 1. For example, computer graphics programs use inverse square roots to compute angles of incidence and reflection for lighting and shading. The algorithm is best known for its implementation in 1999 in the source code of Quake III Arena, a first-person shooter video game that made heavy use of 3D graphics. The algorithm only started appearing on public forums such as Usenet in 2002 or 2003. At the time, it was generally computationally expensive to compute the reciprocal of a floating-point number, especially on a large scale; the fast inverse square root bypassed this step.

id Tech 3, popularly known as the Quake III Arena engine, is a game engine developed by id Software for their video game Quake III Arena. It has been adopted by numerous games. During its time, it competed with the Unreal Engine; both engines were widely licensed.

id Tech 4, popularly known as the Doom 3 engine, is a game engine developed by id Software and first used in the video game Doom 3.

Quake 4 is a military science fiction first-person shooter video game, the fourth title in the Quake series. The game was developed by Raven Software and published by Activision. Raven Software collaborated with id Software, the creators and developers of preceding Quake games. id Software supervised the development of the game as well as providing the id Tech 4 engine upon which it was built. Quake 4 went gold in early October 2005 and was released on October 18, 2005 for Microsoft Windows and later for Linux and OS X, as well as being a launch title for the Xbox 360. A special DVD Collectors Edition was released, including promotional material and the game Quake II with its expansions, The Reckoning and Ground Zero. The Xbox 360 version of Quake 4 is based on the Special Collectors Edition, and includes Quake II. On August 4, 2011, the game was made available through Steam.

QuArK, is a free and open-source program for developing 3D assets for a large variety of video games, mostly first-person shooters using engines similar to or based on the Quake engine by id Software. QuArK runs on Microsoft Windows.

Quake Champions is a first-person shooter developed by id Software and published by Bethesda Softworks that was released on August 22, 2017. It is the fifth main entry in the Quake series following 2005's Quake 4. Since August 10, 2018, it has been free-to-play.

Quake II is a first-person shooter video game released in December 1997. It was developed by id Software and published by Activision. It is not a direct sequel to Quake; id decided to revert to an existing trademark when the game's fast-paced, tactile feel felt closer to a Quake game than a new franchise. The game's storyline is continued in its expansions and Quake 4.

The Quake II engine is a game engine developed by id Software for use in their 1997 first-person shooter Quake II. It is the successor to the Quake engine. Since its release, the Quake II engine has been licensed for use in several other games.

Quake III Arena is a 1999 multiplayer-focused first-person shooter developed by id Software. It is the third game in the Quake series and also the first spin-off to Quake; it differs from previous games by excluding a story-based single-player mode and highly focusing on multiplayer gameplay. The single-player mode is played against computer-controlled bots. It features music composed by Sonic Mayhem and Front Line Assembly founder Bill Leeb.
