Radiant is a game level editor for Quake Engine based games originally developed by id Software and Loki Software.


An off shoot of the program Q3Radiant, GtkRadiant is able to create levels for GoldSrc engine based games (Half-Life 1, Counter-Strike, Team Fortress Classic) as well. GtkRadiant is open source, licensed under the GPL, and is available for free.
