Unidoom DM (series)

The Unidoom DM series is a series of deathmatch WADs created by Clan Unidoom from 2002 to 2004. They are regularly played in ZDaemon's deathmatch tournaments and Skulltag's Friday Night Fragfest, and are a source of inspiration for deathmatch mappers in both the ZDaemon and Skulltag communities.

UDM1
UDM1 was released on January 1st, 2002. Containing sixteen deathmatch maps, two deathtag maps, and two parody maps, it became an instant hit in the Deathmatch community. Notable DM mappers such as TLSDM's ChronoHunter have stated UDM1 as their inspiration to map.

Controversy
Two issues have been raised about UDM1: The use of Skulltag textures without the permission of Carnevil and the plagiarism of MAP06, although the latter was not known until it was revealed by deathz0r a few years later.

UDM2
UDM2 development had started shortly after the release of UDM1, but lack of motivation slowed progress on UDM2 down to a near-halt throughout 2002. UDM2 was eventually released on March 2nd, 2003 and uploaded onto various servers (but initially rejected from /idgames, see Controversy). It contains twelve deathmatch maps, a parody map, and a credits map.

The standout map from UDM2 is the tribute map to Super Mario Bros 3, which uses sprites and textures from that game.

Controversy
Like UDM1, UDM2 had used Skulltag textures without the permission of Carnevil. In response to UDM2 being uploaded to /idgames, Carnevil had sent an email to the archive maintainer Ty Halderman requesting it to be removed from the server. This action had caused a flamewar in the Skulltag IRC channel, in which Carnevil eventually agreed to allow Clan Unidoom to reupload UDM2.

UDM3
The second sequel to UDM1 was released on December 25th, 2005. Unlike UDM1 and UDM2, a much broader variety of mappers contributed to this map pack. Also, unlike the earlier WADs, UDM3 did not contain Skulltag textures, allowing for a smaller file size. UDM3 contains sixteen deathmatch maps, two parody maps, and a credits map; it also introduced a new palette which modified the green and blue colours to provide a brighter environment.

The standout map from UDM3 is Citadel of Unidoom, which was an attempt by deathz0r to have as many Unidoom members as possible cooperate in the creation of a city containing their own buildings. Although the layout was not completed due to lack of time, it was still a highly playable free-for-all map.
