History of WADs
Development of ''Doom''
When developing ''Doom'', id Software was aware that many players had tried to create customUtilities and WADs
Immediately after the initial shareware release of ''Doom'' on December 10, 1993, players began working on various tools to modify the game. On January 26, 1994, Brendon Wyber released the first public domain version of the Doom Editing Utility (DEU) program on the Internet, a program created by ''Doom'' fans which made it possible to create entirely new levels. DEU continued development until May 21 of the same year. It was made possible by Matt Fell's release of the Unofficial ''Doom'' specifications. Shortly thereafter, ''Doom'' players became involved with further enhancing DEU. Raphaël Quinet spearheaded the program development efforts and overall project release, while Steve Bareman lead the documentation effort and creation of the DEU Tutorial. More than 30 other people also helped with the effort and their names appear in the README file included with the program distribution. Yadex, a fork of DEU 5.21 for Unix systems running the X Window System, was later released under the GNU/GPL license. Carmack additionally released the source code for the utilities used to create the game, but these were programmed in Objective-C, for NeXT workstations, and were therefore not directly usable the mass userbase of IBM PC compatible. Jeff Bird is credited with creating the first custom WAD for ''Doom'', called ''Origwad'', on March 7, 1994. Soon, countless players were creating custom WADs and sharing them over AOL, the CompuServe forums, and other Internet-based channels. Many of the WADs were made in the style of the base game, others were based on existing television program, TV series, Film, movies, or original themes. Some of the id Software staff have revealed that they were impressed by some of the WADs. John Carmack later said the following about a ''Star Wars''-themed modification: Another early modification is ''Aliens TC'', a total conversion based on the movie ''Aliens (film), Aliens''. Even though WADs modified ''Doom'' by replacing graphics and audio, the amount of customization was somewhat limited; much of the game's behavior, including the timing and strength of weapons and enemies, was hard-coded in the ''Doom'' executable file and impossible to alter in WADs. DeHackEd, a ''Doom'' editing program created by Greg Lewis, addressed this by letting users modify parameters inside of the ''Doom'' executable itself, allowing for a greater degree of customization.Commercial WADs
Around 1994 and 1995, WADs were distributed primarily through Bulletin board system, BBSs and via CD collections found in computer shops or bundled together with instruction guides for level creation, while in later years Internet File Transfer Protocol, FTP servers became the primary method for obtaining these works. Although the ''Doom'' software license required that no profit be made from custom WADs, and Shawn Green (game designer), Shawn Green objected to people selling their WADs for money, some WAD sets and shovelware bundles were nonetheless obtainable for a price at certain outlets. During this time, id Software was working on their next game, ''Quake (video game), Quake'', using new technology, but started projects picking up the most talented WAD makers from the ''Doom'' community to create official expansions and to compete with the unauthorized collection CDs. The team produced the 21 ''Master Levels for Doom II, Master Levels'', which, on December 26, 1995, were released on a CD along with ''Maximum Doom'', a collection of 1,830 WADs that had been downloaded from the Internet. In 1996, ''Final Doom'', a package of two 32-level megawads created by TeamTNT, was released as an official id Software product. Various first-person shooter games released at the time use the ''Doom'' engine under a commercial license from id Software, as such essentially being custom WADs packaged with the ''Doom'' engine, such as ''Hacx: Twitch 'n Kill'' (1997). In addition to the many people who contributed to commercially released WADs, various authors became involved with the development of other games: * Kenneth Scott, who contributed artwork to ''Hacx: Twitch 'n Kill'', later became the art director at id Software and 343 Industries on the post-Bungie ''Halo (franchise), Halo'' games. * Tim Willits, who contributed two levels to ''Master Levels for Doom II'', later became the lead designer at id Software. * Casali brothers, Dario Casali, author of a quarter of ''Final Doom'', was hired by Valve Corporation, Valve to work on ''Half-Life (video game), Half-Life''. * Sverre Kvernmo, designer of five levels in ''Master Levels for Doom II'' and member of TeamTNT, was hired by Ion Storm for ''Daikatana''. * Iikka Keränen, author of several ''Doom'' WADs and later ''Quake'' mods, was hired by Ion Storm to create levels for ''Anachronox'' and ''Daikatana'', and by Looking Glass Studios to create levels for ''Thief II: The Metal Age''. Keränen was later hired by Valve. * John Anderson (level designer), also known as "Dr. Sleep", author of five levels in ''Master Levels for Doom II'' and E4M7 in ''The Ultimate Doom'', later worked on ''Blood (video game), Blood'', ''Unreal (1998 video game), Unreal'', and ''Daikatana''. * Matthias Worch (level designer) joined Ritual Entertainment to work on ''SiN''. He later contributed to the ''Unreal'' series.Source port era
Around 1997, interest in ''Doom'' WADs began to decline, as attention was drawn to newer games with more advanced technology and more customizable design, including id Software's own ''Quake (video game), Quake'' and ''Quake II''. On December 23, 1997, id Software released the source code to the Doom engine, ''Doom'' engine, initially under a restrictive license. On October 3, 1999, it was released again under the terms of the GNU General Public License, GNU GPL-2.0-or-later. With the source code available, it became possible for programmers to modify any aspect of the game, remove technical limitations and Software bug, bugs, and add entirely new features. These engine modifications, or List of Doom source ports, ''Doom'' source ports, have since become the target for much of the WAD editing activity, and with the decline of MS-DOS, using a source port became the only feasible way to play ''Doom'' for most people. Several source ports are in active development, and ''Doom'' retains a strong following of WAD creators.Types of WADs
Levels
The most common type of WAD consists of a single Level (video gaming), level, usually retaining the theme of the original game, but possibly including new music and some modified graphics to define a more distinctive setting or mood. Both single-player and deathmatch (gaming), deathmatch Multiplayer video game, multiplayer levels are common. WADs may have a level pack in the form of an ''episode'', replacing nine levels, and sometimes in the form of a ''megawad'', which replaces 15 or more levels in the game (27 in ''Doom'', 32 in ''Doom II'', 36 in ''The Ultimate Doom'').Total conversions
A WAD that gives the game an overhaul to incorporate an entirely different Campaign setting, game setting, character set, and story, instead of simply providing new levels or graphic changes, is called a ''total conversion''. The phrase was coined by Justin Fisher, as part of the title of ''Aliens TC'', or ''Aliens Total Conversion''. Add-ons that provide extensive changes to a similar degree but retain distinctive parts or characteristics of the original games, such as characters or weapons, are often by extension called ''partial conversions''.List of WADs

* * ''D!Zone'' – Created by WizardWorks, an expansion pack featuring hundreds of levels for ''Doom'' and ''Doom II'' . ''D!Zone'' was reviewed in 1995 in ''Dragon (magazine), Dragon'' by Jay & Dee in the "Eye of the Monitor" column. Jay gave the pack 1 out of 5 stars, while Dee gave the pack 1½ stars. * ''Origwad'' – Created by Jeff Bird and released on March 7, 1994, it is notable for being the first custom WAD to be released for ''Doom''. ''Origwad'' consists of a single level with two rooms separated by one door, and a total of six enemies, making it very basic compared to later WADs. * ''The Harris levels'' – ''Doom'' and ''Doom II'' levels created by Eric Harris and Dylan Klebold#Eric Harris, Eric Harris, one of the two perpetrators of the Columbine High School massacre, believed to have surfaced on the Internet in 1996 or 1997, but were taken down by the FBI after the 1999 massacre. Downloads for the levels Deathmatching in Bricks (BRICKS.WAD), Hockey.wad (HOCKEY.WAD), KILLER (KILLER.WAD), Mortal Kombat Doom (FIGHTME.WAD), Outdoors (outdoors.wad), Station (STATION.WAD), and UAC Labs (UACLABS.WAD) have been found in the years since. Eric Harris and Dylan Klebold#Dylan Klebold, Dylan Klebold, a friend of Harris and the other perpetrator of the massacre, was credited by Harris for playtesting Deathmatching in Bricks. The ENDOOM screen for UAC Labs shows the names of other WADs made by Harris, though they have since been Lost artworks, lost: Assault, Techout, Thrasher, Realdeth, and Realdoom, which is a patch for another WAD. UAC Labs was mentioned in Doomworld's Top 10 Infamous WADs list. *''Lullaby,'' a level created by ''Danlex'' in 2021 which contained surreal visuals. *''National Videogame Museum,'' a recreation of the real life National Videogame Museum (United States), National Videogame Museum by employee Chris Bacarani. The level took over a year to make, and is featured as an exhibit in the physical museum. *''Nuts!'' – Released in 2001, ''Nuts'' is one of the first documented joke WADs. ''Nuts'' consists of a single room, with an invulnerability power up, plasma rifle, BFG (weapon), BFG, and 10,617 enemy monsters. Its creator, B.P.R.D, created multiple sequels, and a version of ''Nuts'' was made in Dusk (video game), Dusk. * ''The Sky May Be'' – A notable joke WAD, most of the game takes place in an oversized sector, where many textures are replaced with solid colors, and many sounds replaced with audio from Monty Python's Flying Circus. The WAD was mentioned in Doomworld's The Top 10 Infamous WADs list and it is sometimes considered to be one of the worst WADs ever created. * ''UAC Military Nightmare'' – A List of Doom source ports#ZDoom and derivatives, Skulltag WAD made by "Terry" in 2008 which was notorious for its use of vulgar scripts, Jump scare, jump scares, strange graphics, absurd difficulty, and otherwise-useless data that existed to either bloat the WAD's file size or tamper with the player's settings. The WAD itself was removed from Doomworld in 2014 due to the aforementioned useless data, but has since been reuploaded with said data removed. This WAD spawned a genre of WADs known as "Terrywads", or "Terry Traps", which contain similar content to ''UAC Military Nightmare''. In 2008, ''UAC Military Nightmare'' received a ''Cacoward'' for Worst WAD, wherein it is described as "the worst wad file the world has ever known." *''Lilith'' – A mod created in 2017 that uses Glitch, glitches in the Zdoom sourceport to create graphical and musical distortion, and changes in enemy behavior, resulting in a "glitchcore nightmare." ''Lilith'' was also a winner in the 2017 ''Cacowards.''Freedoom
Freedoom is a project aiming to create a Free software, free replacement (modified BSD License) for the set of Computer graphics, graphics, music, sound effects, andEditing
Many level editors are available for ''Doom''. The original Doom Editing Utility (DEU) was ported to a number of operating systems, but lost significance over time; many modern ''Doom'' editors still have their roots in DEU and its editing paradigm, including DETH, DeePsea, Linux Doom Editor, and Yadex and its fork Eureka. Other level editors include WadAuthor, Doom Builder (released in January 2003), and Doom Builder 2 (released in May 2009 as the successor to Doom Builder). Some ''Doom'' level editors, such as Doom Builder and Doom Builder 2, feature a 3D editing mode. As of now, these two have been discontinued, but a newer fork has been released and is regularly updated, known as GZDoom Builder. GZDoom Builder is also discontinued and is now being maintained as Ultimate Doom Builder. Many specialized ''Doom'' editors are used to modify graphics and audio lumps, such asXWE, SLADE, Wintex, and SLumpEd. The DeHackEd executable patching utility modifies monsters, items, and weapon behavior. In ZDoom, users can create new monsters, weapons, and items through a scripting language called DECORATE, made to address many of the shortcomings of DeHackEd, such as not being able to add new objects, and not being able to deviate far from the behavior of the original weapons and monsters.WAD2 and WAD3
In ''Quake'', WAD files were replaced with List of file formats#Video game data, PAK files. WAD files still remain in ''Quake'' files, though their use is limited to textures. Since WAD2 and WAD3 use a slightly larger directory structure, they are incompatible with ''Doom''.References
