Ok so I've hopped all over german sites and what not finding maps. Rather than wait for a supported maplist to be issued I just cracked open fritz0.pk3 with pakscape to see what .nav files were available.
I've located basically every map except one, the radar.nav is very, very generic and I've found at least six maps that could theoretically be it but since one generally names .nav the exact same thing as the .pk3, the actual map title could be anything from "Jimmy's Three ring Circus 1929" to "Flea market electronics" there's just no way to tell.
If anyone could clue me in to the actual map title so I can complete my maplist that would make my day.
