Stian Skjondal (Zero Signal)

Stian Skjondal (alias Zero Signal, shortened to zsignal) is a Norweigan graphic artist and level designer who was active in the Doom community between 1998 and 2000. He was an early adopter of ZDoom's support for ACS scripting, creating PWADs that required jumping and mouselook for level progression. Zero Signal released the Xorg series of levels for ZDoom that supported both single player and deathmatch play. He also created three custom sky WADs available for use by other level designers. His sky environments mostly notably appear in QDOOM and Crucified Dreams.

In 1999, Zero Signal released ZDoom partial conversion Securitron and its episode 2 sequel that featured Quake enemies and a man-versus-machine storyline based on, an album by industrial metal band Fear Factory. By early 2000, a third episode was in development with the project's web site showcasing new custom enemies and level design screenshots. However episode 3 remained unfinished as Zero Signal moved onto modding for other games.
