German Quake "shovelware" compilation CD from 1996

Someone posted this on Twitter:

And I found ISO of this gem:

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? :slight_smile:

CD has tools and mods too.
