Description
DOS sector-based editor for Doom, Doom2 and Heretic by Jeff Rabenhorst. Supports texture/sprite wads. Very powerful, but uses only the 640 K conventional memory. Good interface. Easy to switch nodesbuilder by means of editing a batch file (default WARM). Editor of choice for Columbine killer Eric Harris, who thanked the creators in the credits of "UAC Labs" and "Bricks".
