Virtus Deathmatch Maker
(March 12, 2018)
Virtus Deathmatch Maker (archived website) touts itself as the first id-authorized level editor for Quake and was sold as a proper big-box PC title in 1996. The program takes a unique approach to creating levels where template sections of a level can be dropped into the overhead grid and strung together, creating levels without the need to worry about piecing every bit of architecture together yourself. In fact, a drag-and-drop approach is taken with everything from placing enemies to texturing walls.
On the compiling side, Deathmatch Maker takes an all-in-one approach with a hard-coded set of compilers. The program also features importing and exporting in the traditional map format, however, so other compilers may be used if desired. The program comes with some new enemies and textures, featured in a custom progs.dat and WAD that also includes the textures of the base game.
Deathmatch Maker comes with two brand new example episodes that are fully playable as a partial conversion without the need for the program itself. These are also available for download in the "Supplementary Tools and Example Levels" download below. The sources for all of Virtus' example maps are packaged with the program itself, which the documentation notes are intentionally broken as a sort of "tutorial" on troubleshooting and level design.
