And I found ISO of this gem: https://archive.org/details/krogersoftwaregmbhquke
Structure of the CD is rather lame, but I went through maps, and found few, that are not available on Quaddicted.
There are even 2 test "maps" with BSP ver. 23 They work only on QTest!
Are these the first Quake maps ever made? :)
CD has tools and mods too.
