Starting with the Wolfenstein 3D franchise and continuing with the Doom and Quake series, Id pushed the boundaries of video game technology — particularly 3D computer graphics technology — and creates game engines that are heavily used throughout the video game industry.

During its early days, Id Software produced much more varied games ; these include the early 3D first person shooter experiments that led to Wolfenstein 3D and Doom — Hovertank 3D and Catacomb 3D.

With an emphasis on trying to avoid detection for as long as possible, Castle Wolfenstein and its sequel are considered by gamers to be prototypical stealth-based games — some of the first in a genre that wouldn't gain popularity until the late 1990s.

The event was also highlighted by a slew of major announcements, including id Software's new intellectual property RAGE, a sneak peek at the " id Tech 5 " engine, a 10-2-2007 release date for ET: QW, updates on the new Return to Castle Wolfenstein game title and major motion picture, the revelation that old id Software titles were to be made available via Steam, the upcoming debuts of Quake Arena Arcade, Quake Zero ( now officially named Quake Live ), and Quake Arena DS, also — in an unprecedented move — the announcement of the dates and venue for the next QuakeCon before the current year's event was even finished.

A third Wolfenstein sequel has been released by Raven Software, using the Id tech 4 engine.

Raven has a history of working with id Software: After using id's engines for many of their games ( from Heretic in 1994 ), they took over development of id's Quake franchise for Quake 4 and the new iteration of id's Wolfenstein series.

A sequel called Wolfenstein was developed by Raven Software and id Software and published by Activision, and released on August 18, 2009.

The game engine for Doom 3, id Tech 4, has been licensed out for the use of other developers, such as in Human Head Studios ' Prey, Raven Software's Quake 4, Splash Damage's Enemy Territory: Quake Wars, Raven Software's Wolfenstein and Splash Damage's Brink ; however id Tech 4 has not been widely licensed compared to Epic Games ' Unreal Engine.

The development of Doom started in 1992, when John D. Carmack developed a new 3D game engine, the Doom engine, while the rest of the id Software team finished the Wolfenstein 3D prequel, Spear of Destiny.

The shareware distribution method was initially employed by Id Software through Apogee Software to sell their products, such as the Commander Keen, Wolfenstein and Doom games.

Id Software has developed their own game engine for each of their titles when moving to the next technological milestone, including Commander Keen, Wolfenstein 3D, Shadowcaster, DOOM, Quake, Quake II, and Quake III, as well as technology used in making Doom 3.

Some Id Software titles ported to Linux are Doom ( the first Id Software game to be ported ), Quake, Quake II, Quake III Arena, Return to Castle Wolfenstein, Wolfenstein: Enemy Territory, Doom 3, Quake 4, and Enemy Territory: Quake Wars.

Since Id Software and some of its licencees released the source code for some of their previous games, several games which were not ported ( such as Wolfenstein 3D, Spear of Destiny, Heretic, Hexen, Hexen II, and Strife ) can run on Linux and other operating systems through the use of source ports.

Eighteen months after their release of Wolfenstein 3D, in 1993 Id Software released Doom which would again set new standards for graphic quality and graphic violence in computer gaming.

Id Software was the target of controversy over two of their most popular games, Doom and the earlier Wolfenstein 3D:

Employees of Id Software are quoted in The Official DOOM Player Guide about the reaction to Wolfenstein, claiming it to be ironic that it was morally acceptable to shoot people and rats, but not dogs.

id Software, the creators of Wolfenstein 3D, oversaw the development and were credited as executive producers.

From very early on in the game's development, Daikatana was advertised as the brainchild of John Romero, a man famous for his work at id Software in the development of Wolfenstein 3D, Doom and Quake.

Spear of Destiny, often also called Spear, Wolfenstein 3D: Spear of Destiny or just SoD, is a 1992 first-person shooter computer game developed by id Software and published by FormGen Corporation, and is the prequel to id Software's Wolfenstein 3D.

He is best known as a co-founder of id Software and was a designer for many of their games, including Wolfenstein 3D, Dangerous Dave, Doom and Quake.

He wrote many of the tools used at id Software to create their games, including DoomEd ( level editor ), QuakeEd ( level editor ), DM ( for deathmatch launching ), DWANGO client ( to connect the game to DWANGO's servers ), TED5 ( level editor for the Commander Keen series, Wolfenstein 3D and Spear of Destiny ), IGRAB ( for grabbing assets and putting them in WAD files ), the installers for all the games up to and including Quake, the SETUP program used to configure the games, and several others.

Raven is the common name given to several larger-bodied members of the genus Corvus — but in Europe and North America the Common Raven is normally implied.

Females are 74 – 84 cm long, and the males are a larger 80 – 98 cm long — making them the third-largest passerine bird after the Thick-billed Raven and the Common Raven.

The eponymous Jeremiah is a semi-loner who has spent the last 15 years travelling back and forth across the United States, seeking out a living and looking for a place called " Valhalla Sector ," ( the remains of Raven Rock ) which his father — a viral researcher — had mentioned to Jeremiah as a possible refuge shortly before disappearing into the chaos of " the Big Death.

In its present stronghold — the state of Tasmania — the Forest Raven is one of only three native birds that have no legal protection outside national parks and other reserves.

It is one of several species of corvid that are entirely black, though it can be distinguished from the other two such birds in its range — from the Common Raven ( C. corax ) by size and behavior and from the Fish Crow ( C. ossifragus ) by call ( but see below ).

The population sometimes known as the Punjab Raven — described as Corvus corax laurencei ( also spelt lawrencii or laurencii ) by Allan Octavian Hume but more often considered synonymous with subcorax — is restricted to the Sindh district of Pakistan and adjoining regions of northwestern India.

Marvel Comics was rechristened Marvel Mystery Comics with issue # 2 ( Dec. 1939 ) — the magazine would continue under that title through # 92 ( June 1949 ) before becoming Marvel Tales through # 159 ( Aug. 1957 ) — and Timely began publishing additional series, beginning with Daring Mystery Comics # 1 ( Jan. 1940 ), Mystic Comics # 1 ( March 1940 ), Red Raven Comics # 1 ( Aug. 1940 ), The Human Torch # 2 ( premiering Fall 1940 with no cover date and having taken over the numbering from the unsuccessful Red Raven ), and Captain America Comics # 1 ( March 1941 ).

In the 1960s, versions of the Red Raven system were introduced in Europe and Japan under various names — Teddy in France and the Netherlands, Mamil Moviton in Italy, etc.

She co-starred in two graphic novels — Fury / Black Widow: Death Duty with Nick Fury, Marvel UK's Night Raven and Punisher / Black Widow: Spinning Doomsday's Web with the Punisher — as well as a three-issue arc, " The Fire Next Time ", by writer Scott Lobdell and penciller Randy Green, in Journey into Mystery # 517 – 519 ( Feb .– April 1998 ).
