Wolfenstein 3D

Wolfenstein 3D is a first-person shooter presented with rudimentary 3D graphics. The game is broken up into levels, each of which is a flat plane divided into areas and rooms by a grid-based pattern of walls and doors, all of equal height. Each level is themed after Nazi bunkers and buildings. To finish a level, the player must traverse through the area to reach an elevator.

Levels—ten in the original episodes—are grouped together into named episodes, with the final level focusing on a boss fight with a particularly difficult enemy. While traversing the levels, the player must fight Nazi guards and soldiers, dogs, and other enemies while managing supplies of ammunition and health. The player can find weapons and ammunition placed in the levels or can collect them from dead enemies; weapons include a knife, a pistol, a submachine gun, and a rapid-fire chain gun. The player can also find keys that allow them to pass through locked doors.

Wolfenstein 3D is divided into two sets of three episodes: "Escape from Castle Wolfenstein", "Operation: Eisenfaust", and "Die, Führer, Die!" serve as the primary trilogy, with a second trilogy titled The Nocturnal Missions including "A Dark Secret", "Trail of the Madman", and "Confrontation". J." Blazkowicz, an American spy of Polish descent, and the game follows his efforts to destroy the Nazi regime.

In "Escape", Blazkowicz has been captured while trying to find the plans for Operation Eisenfaust (Iron Fist) and imprisoned in Castle Wolfenstein, from which he must escape. "Operation: Eisenfaust" follows his discovery and thwarting of the Nazi plan to create an army of undead mutants in Castle Hollehammer, while in "Die, Führer, Die!" he infiltrates a bunker under the Reichstag, culminating in a battle with Adolf Hitler in a robotic suit equipped with four chain guns.

In October–December 1990, a team of employees from programming studio Softdisk calling themselves Ideas from the Deep developed the three-part video game Commander Keen in Invasion of the Vorticons, the first game in the Commander Keen series. The group, who worked at Softdisk in Shreveport, Louisiana, developing games for the Gamer's Edge video game subscription service and disk magazine, was composed of programmers John Romero and John Carmack, designer Tom Hall, artist Adrian Carmack, and manager Jay Wilbur. After the release of the game in December through shareware publisher Apogee Software, the team planned to quit Softdisk and start their own company. When their boss, Softdisk owner Al Vekovius, confronted them on both their plans and their use of company resources to develop the game—the team had created it on their work computers, both in the office after hours and by taking the computers to John Carmack's house on the weekends—the team made no secret of their intentions. After a few weeks of negotiation, the team agreed to produce a series of games for Gamer's Edge, one every two months.

Ideas from the Deep, now formally established as id Software, used some of these to prototype ideas for their own games. Adrian Carmack used them to push his preferred, dark art style, while John Carmack began to experiment with 3D computer graphics, which until then was largely the purview of flight simulators such as Wing Commander (1990) and slower adventure games such as Mercenary (1985). Carmack found that this was largely due to the limitations of personal computers of the time, which had difficulty displaying a fast action game in 3D due to the number of surfaces it needed to calculate, but felt that the increasing computational power of PCs meant that it may be possible. During 1991, he experimented with limiting the possible surfaces the computer needed to display, creating game levels with walls designed only on a flat grid rather than with arbitrary shapes or angles.

The developers had no clear expectations for Wolfenstein's commercial reception, but hoped that it would make around US$60,000 in its first month; the first royalty check from Apogee was instead for US$100,000. The game was selling at a rate of 4,000 copies a month by mail order. PC Zone quoted a shareware distributor as saying Wolfenstein 3D was the top shareware seller of 1992. By the end of 1993, sales of the Apogee episodes of Wolfenstein 3D as well as Spear of Destiny had reached over 100,000 units each, with the Apogee game still selling strongly by the end of the year as its reach spread without newer retail titles to compete with it for shelf space.

By mid-1994 150,000 shareware copies were registered and id Software had sold another 150,000 retail copies of Spear of Destiny; the company estimated that one million shareware copies were distributed worldwide. Over 20 percent of its sales were from outside of the US, despite the lack of any marketing or non-English description and despite the game being banned from sale in Germany due to its inclusion of Nazi symbols by the Federal Department for Media Harmful to Young Persons in 1994, and again in 1997 for Spear of Destiny. Japanese gaming magazine Famitsu reviewed the game five months after release, describing it as: "View from the character's point of view: It's a real shooter. The game is easy to play, and it runs well ...

Wolfenstein 3D has been called the "grandfather of 3D shooters", specifically first-person shooters, because it established the fast-paced action and technical prowess commonly expected in the genre and greatly increased the genre's popularity. It has also been called "the Citizen Kane of shooters". Although some prior computer shooting-based games existed, they were generally scrolling shooters, while Wolfenstein 3D helped move the market towards first-person shooters. It has also been credited with confirming shareware distribution as a serious and profitable business strategy at the time; VideoGames & Computer Entertainment claimed in September 1992 that the game "justified the existence of shareware", and in July 1993 Computer Gaming World claimed that it "almost single-handedly" demonstrated the viability of shareware as a method of publishing, leading to a wave of other shareware first-person shooters. The game's high revenue compared to prior, smaller 2D titles led Apogee as well as others in the shareware games industry to move towards larger, 3D titles built by larger development teams.

During development, id approached Sierra Entertainment, then one of the biggest companies in the industry and employer of several of their idols, with the goal of seeing if they could make a deal with the company. 5 million and turn it into an in-house development studio. The team was excited by the deal, but had felt there was a large culture clash between the two companies during their visit to Sierra and were hesitant to accept; Romero proposed asking for US$100,000 in cash up front as part of the deal rather than solely accepting payment in Sierra stock as a measure of Williams's seriousness. Williams refused, which id interpreted to mean that Williams did not truly recognize the potential of Wolfenstein 3D and the company, and the deal fell through, causing id to decide to remain an independent company for the foreseeable future.
