Doom (video game)

Doom is a first-person shooter (FPS) computer game developed by id Software and released in 1993. With its innovative use of 3D graphics and visceral gameplay, Doom changed standards for interactive entertainment and came to define the emerging FPS genre for years after its release. Distributed as shareware at a time when the number of people with access to the Internet was growing explosively, it changed social aspects of computer gaming by popularizing multiplayer deathmatch and by enabling players to create and share custom-built modifications to the game.

Gameplay

Doom can be played in either single-player or multiplayer mode. The single-player mission is set on the moons of Mars which, due to a catastrophic teleportation experiment, have been invaded by demons from Hell. The player takes the role of the only surviving human, a nameless space marine — "one of Earth's toughest, hardened in combat and trained for action", who must fight his way out of the infested moon bases.

Development and technology

Game engine

Id Software did not have any definite plans for its next game after releasing Wolfenstein 3D in May 1992. While the designers put together an expansion for Wolfenstein 3D called Spear of Destiny, lead programmer John Carmack isolated himself to spearhead the development of a new game engine with support for more realistic three-dimensional worlds. He figured out the tricks needed to render diagonal walls, texture mapping of floors, and variable lighting. An early version of the engine was licensed to Raven Software for use in the game Shadowcaster.

Game design

Id Software started building a game around Carmack's engine in September 1992. Designer Tom Hall wanted to make a new Commander Keen game; he was voted down since the rest of the team thought a darker game would do the engine better justice. Id Software then negotiated rights to make a game based on the science fiction-action film Aliens, but the plan was soon abandoned due to concerns of creative freedom. John Carmack instead came up with the idea "Aliens meets Evil Dead 2", or "demons versus technology". This theme also drew from the team's most recent Dungeons & Dragons campaign, which had ended with demons overrunning the entire planet. Carmack came up with the name Doom after watching the film The Color of Money, in which Tom Cruise's character replies "Doom" when asked what he carries in his cue-case. According to Carmack, "That, and the resulting carnage, was how I viewed us springing the game on the industry."

The first draft for the game's design was prepared by Tom Hall, who wrote a comprehensive design document called the Doom Bible. He envisioned gameplay wholly different from the simple-minded action of Wolfenstein 3D: an elaborate storyline, multiple player characters with different personalities and abilities, and interactive features such as in-game computer terminals. He began designing levels based on authentic military architecture, decorated with realistic-looking wallpapers, floor tiles and office equipment. However, the rest of the id Software staff preferred the action-oriented style of Wolfenstein 3D and thought Hall's design emphasized realism at the cost of entertainment. The conflict ended with Tom Hall's resignation in the summer of 1993, and much of the Doom Bible was discarded.

Doom obtained its characteristic, more abstract, level style when John Romero instead took up level design. He explored "large spaces with more complex sector geometry", used altitude changes abundantly, and made his levels "flow so the player will revisit areas several times [to] better understand the 3D space". He further created "easily recognizable landmarks in several places for easier navigation", made conscious use of contrast in lighting and proportion, and filled his levels with secret areas.

Since Romero was both a programmer and a level designer, he only had time to design the game's first episode. Ten weeks before release, Sandy Petersen was hired to help out, and in that time finished the last two episodes, incorporating Tom Hall's drafts. There are notable stylistic differences between Romero's and Petersen's levels. Romero's levels are generally considered more visually pleasing; others at id Software went so far as describing Petersen's levels as "downright ugly". David Kushner characterizes Petersen's design as "cerebral" and Romero's as "brutal".

Sound and graphics

The game's sprites and textures were designed by Adrian Carmack and Kevin Cloud, who took inspiration from the biomechanical art of H. R. Giger, the mythos of H. P. Lovecraft, and creatures from Dungeons & Dragons (the Cacodemon is directly based on the front cover illustration of the 1987 edition Manual of the Planes).

The artists found that it was difficult to manually draw sprites that would do justice to the new graphics engine. They therefore turned to blue screen capture to create several of the character graphics. Adrian Carmack created clay sculptures for the player character, the Cyberdemon, and the Baron of Hell; Gregor Punchatz was contracted to create the Spider Mastermind in latex. The sculptures were photographed from five to eight different angles so that they could be rotated in-game, and finally touched up, colored, and animated digitally. The shotgun and pistol graphics were created from photographs of toy weapons, while the chainsaw was created from photographs of a McCulloch Eager Beaver. Finally, Don Ivan Punchatz supplied the package art and logo design.

Robert Prince, who had scored Wolfenstein 3D, was hired to supply the music and sound effects. He and Romero recorded original sounds which he mixed with various stock sound effects, a "puree of animal sounds" for the monsters. He then enhanced the sounds by doubletracking them with his own voice imitations, recorded in reverse.

Prince created a MIDI soundtrack ranging in style from heavy metal to ambient "moody background music". Id Software first requested that Prince would compose nothing but heavy metal, but he thought that the style was not appropriate for all levels. As many players have noted, some of the tracks are uncredited covers of songs by heavy metal bands such as Metallica, Pantera, and Slayer. Prince has a law degree and, according to Romero, "knew the legal amount of sampling that he could do without getting into trouble".

Impact

Numerous publications have ranked Doom among the most influential games of all time. Doom received Game of the Year awards by both PC Gamer and Computer Gaming World in 1994. It also received the Award for Technical Excellence from PC Magazine, and the Best Action Adventure Game award by the Academy of Interactive Arts & Sciences. PC Gamer named it the most influential game of the decade in 2004, and second greatest PC game of all time in 2005. In 2001, Doom was voted the greatest game of all time in a poll among over 100 game developers and journalists conducted by GameSpy.

There is a spectrum of opinions regarding what should be considered the primary the cause for Doom's success. Certainly, the following factors all contributed to some extent:

• Widespread distribution by shareware
• Simultaneous emergence of the Internet
• Advanced 3D graphics and immersive gameplay
• Support for multiplayer gaming
• Support for user-made content

According to John Romero, Doom was successful because it arrived at the right time and synthesized many emerging technologies, which id Software "just capitalized on".

Critics have argued that Doom primarily owed its success to its graphics technology or its explicit graphical violence. Others have praised the game's design. Chris Crawford characterizes the design as "pedestrian ... there's nothing brilliant or innovative ... In design terms, Doom offers nothing that we didn't have in 1981. It is a collection of old and well-established ideas with really snazzy graphics. But the ideas are assembled with great skill. The designers of Doom implemented the basic precepts of good game design with impressive thoroughness." Greg Kasavin holds that Doom "achieved its blockbuster success solely through its incredibly high quality".

Distribution

A common estimate is that 15 million people have played the shareware version of Doom.

...

Doom became notorious for its popularity in workplaces and university computer labs. Id Software had hyped Doom as about to become "the number one cause of decreased productivity in businesses around the world". Indeed, Intel "banned the game after it found its systems swamped", as did many universities in the United States. At the University of Louisville, where "people [sprinted into the computer lab] falling all over each other to play the game", a lab supervisor created a program that would go through the system and delete all copies of Doom. Dennis Chao of the University of New Mexico exploited the game's known "appeal to the target audience of system administrators" when he in 1999 modified Doom into a system administration tool. At Lotus Development, players of the "fiercely fought Lotus League of Doom" were granted access to the network after 6 pm, although installing the game at all was officially disallowed. According to one employee, the game was like a "religious phenomenon" at the Microsoft campus.

Industry and genre influence

Doom immediately became the standard by which similar games were judged. The term "first-person shooter" did not gain popularity until the late 1990s; the years after Doom's release, first-person action games were generally known as "Doom clones".

Id Software themselves capitalized on the success by developing a sequel, Doom II: Hell on Earth, as well as several commercial add-ons.

In 1995, a rumor spread that Doom was more widely distributed than Microsoft's extensively advertised new operating system Windows 95. Bill Gates, seemingly aware of this, asked in an internal e-mail whether he should buy out id Software. Though the plan was never realized, Microsoft did respond to the popularity of Doom by increasing their focus on gaming, particularly by developing the DirectX technology and a Doom port for DirectX as a flagship. To promote Windows 95, Gates made a presentation at a game developers' conference while digitally superimposed into Doom to blast zombies.

Graphics, realism and violence

In the words of Lev Grossman, Doom presented a "three-dimensional virtual world so powerful, compelling and disturbing that it would change the real world around it", whose "fluid, hyperkinetic rhythms [became] part of the visual language of movies and TV". As many players were unfamiliar with the type of interactive 3D graphics, Doom was sometimes half-jokingly said to be the source of "Doom-induced motion sickness" or DIMS.

Doom was and remains notorious for its high levels of violence, gore, and satanic imagery, which have generated much controversy from a broad range of groups. It has been criticized numerous times by religious organizations for its diabolic undertones and was dubbed a "mass murder simulator" by critic and Killology Research Group founder David Grossman. Doom prompted fears that the then-emerging virtual reality technology could be used to simulate extremely realistic killing, and in 1994 led to unsuccessful attempts by Washington state senator Phil Talmadge to introduce compulsory licensing of VR use.

The game again sparked controversy throughout a period of school shootings in the United States when it was found that Eric Harris and Dylan Klebold, who committed the Columbine High School massacre in 1999, were avid players of the game. A rumor spread afterwards that Harris had designed Doom levels that looked like the halls of the high school, populated with representations of Harris's classmates and teachers, and that Harris practiced for his role in the shootings by playing these levels over and over. However, although Harris did design Doom levels, they were not simulations of Columbine High School.

Mods and Internet communities

...

Doom is the subject of several still-active websites. Its longevity can be attributed to the multitude of available WADs and editing tools. In early 2007, the idgames archive contained 15,000 modifications and received some dozen new submissions each week. Since the engine source code was released in 1997, over 50 source ports have been developed that allow Doom to be played on modern operating systems, provide extended editing features, and add new multiplayer game modes. The Compet-N archive contains 6072 speedruns for Doom and its sequels, which makes it the second most popular game for speedrunning after Quake.
