Columbine High School massacre

The Columbine High School massacre occurred on April 20, 1999 at Columbine High School in Jefferson County near Littleton, Colorado, United States. Two teenage students, Eric David Harris and Dylan Bennet Klebold, executed a planned shooting rampage killing 12 other students and a teacher before committing suicide. It is considered to be the third worst school shooting in U.S. history, the worst being the Virginia Tech massacre and the second being the Sandy Hook shooting.

Part of a rash of similar shootings, the events triggered a wide-ranging debate about the effect of violent entertainment, particularly the video games Doom and Quake.

Doomworld posted an editorial defending Doom and the staffers of the time participated in a variety of press interviews. Andrew "Linguica" Stine and Matthew "Mattrim" Dixon were interviewed by SFGate.com. Javier "Dukrous" Heredia defended Doom as part of an interview by CNN.

Doom connection and the Harris levels
Eric Harris was an enthusiast of the Doom series, owning some of the Doom novels and having designed Doom levels under the nicknames "REB", "Rebldomakr", and "RebDoomer". In a videotape recorded before the shooting, Harris expressed enthusiasm for the planned shooting, saying it would be "like fucking Doom." He also pointed out that the shotgun was "Straight out of Doom".

According to a statement made to government "investigators" of the Columbine attack by then-CHS student David Proctor, who occasionally played Doom with Harris and Klebold via modem, Harris told him in 1999 that he'd created a level of Doom that was Columbine High School. Proctor added that another classmate had told him he'd heard the same. Though Harris did release several WADs, the alleged CHS level is not known to be on the internet. After the shootings, many websites refused to provide downloads to any of the levels created by Harris, seeing the shootings as something from which the community should dissociate itself. This position has largely dissipated, although Ty Halderman still regularly rejects the maps from inclusion in the idgames archive.

A PDF containing some of Harris' documents and personal writings includes designs for some of his levels (page 112 onward). On page 272, Harris says "Doom is so burned into my head my thoughts usually have something to do with the game", while on page 321 he references the Doom novels. Harris also wrote about an idea for a seven level WAD known as Tier, though it is unknown if he actually went through with creating it. If he did finish making it, no copies of the WAD are known to be available to download.

Harris's UAC Labs WAD contains comments which appear somewhat disturbing in retrospect. For example, the description ends, "Good luck marine, and dont forget, KILL 'EM AAAAALLLL!!!!!", while the copyright section threatens, "You may NOT change a damn thing with this WAD, if you do, i will blow you up. And it will be cool". Some of Harris's WADs, such as Deathmatching in bricks! and Station, contain a new difficulty setting called "YA FREAKIN NUT!" as a replacement for the Nightmare! difficulty setting, as well as custom sound effects.

Copies of the following files are known to exist:


 * UAC Labs (uaclabs.wad)
 * A two level single player WAD for Doom II: Hell on Earth. The most well-known of the Harris levels, it has an E1-style techbase theme. The WAD includes extra graphics that slightly increase the gore in the monster death animations and a modified ENDOOM screen containing the names of other WADs made by Harris. In the second level, the player is confronted with an enormous arena filled with Demons. Both levels contain bugs that, when played with some source ports, prevent the player from achieving 100% completion in all three categories shown on the stats screen. The first level has a sector tagged as a secret that the player cannot access in any way (even with the no-clip cheat activated), while the second level's item count is listed as having ten items that count toward the total item percentage, though the player can only get nine of them. UAC Labs was released on September 2, 1996.


 * Deathmatching in bricks! (bricks.wad)
 * A deathmatch level for Doom II: Hell on Earth, the name refers to the abundant use of brick textures. The level mainly consists of a number of high rise walkways which players must walk along. Dylan Klebold is credited for playtesting this level. It contains a new sky texture with a black background and white dots of varying sizes representing stars, as well as a new stats screen when the player beats the level showing a black background with red text displaying "PREPARE FOR YOUR NEXT FIGHT!!" and the text "BRICKS (KILL HIM!!)" as the map name on the stats screen. Deathmatching in bricks! was released on March 1, 1996 and took three days to create.


 * Mortal Kombat Doom (fightme.wad)
 * A deathmatch level for Doom II: Hell on Earth consisting of an arena containing four pillars on which the players start. Each player is given a berserk pack, the intention being that the players should fight each other using fists. It contains voice-overs from the Mortal Kombat games and a custom music track. Mortal Kombat Doom was released on July 16, 1996 and took two hours to create.


 * Hockey.wad (hockey.wad)
 * A deathmatch level for Doom II: Hell on Earth consisting of an ice hockey rink and surrounding stadium. Hockey.wad was released on June 13, 1996 and took an hour and a half to create.


 * KILLER (killer.wad)
 * A deathmatch level for Doom II: Hell on Earth consisting of a large open grass arena containing several buildings with weapons. The teleport sound has been changed to Duke Nukem saying "You're Pissing Me Off". The music used in this level is taken from the Zedek's Tomb level in Hexen: Beyond Heretic. KILLER was released on July 19, 1996 and took two hours to create.


 * Station (station.wad)
 * A techbase-themed deathmatch level for Doom II: Hell on Earth consisting of several rooms connected by a single corridor. This WAD was in the top 25 deathmatch WADs on AOL at one point according to the ENDOOM screen for uaclabs.wad. It contains a new sky texture and the BFG sound has been changed to Bruce Campbell saying "Swallow This" from the movie 'Evil Dead 2'. Additional credits for this WAD were given to the creator of a WAD called DeathWorld II: Fragland (made by Tom J. McClure on April 28, 1996, although his name is not mentioned and it is simply called "Fragland" in the text file for Station) for the pool idea and someone named Excaluber for additional ideas. Station was released on July 25, 1996 and took an hour and a half to create.


 * Outdoors (outdoors.wad)
 * A deathmatch level for Doom/The Ultimate Doom. In the Rebdoomer directory at acolumbinesite.com.

The ENDOOM screen for uaclabs.wad mentions the following WADS, although no known copies of them are publicly available:


 * techout
 * assault
 * thrasher
 * realdeth
 * realdoom (a patch, most likely for his realdeth WAD, which is consistently mentioned in the text files for all of the Harris levels; Harris encourages the reader to email him to ask about it)
 * coolname.zip (in the Rebdoomer directory at acolumbinesite.com, though it is not mentioned on the ENDOOM screen for uaclabs.wad and no copies of it are publicly available)
