GtkRadiant

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.

Note:GtkRadiant 1.5 has certain compatibility and stability issues when creating maps for Half-Life, for this reason 1.4 or earlier are recommended instead.
