Oh i see, well i don´t know if was me or my friend but i listed another song, i guess my friend press the action key in every corner of the map haha.tbh i thought that you activated the music where you pick up the parts and then craft them xDDD, not the meteor one.
The changes on you current progress listen pretty well for me, the pap area was pretty fine but iis ok if you want to change the location. The tiger of nine could be a awesome feature on you map, more if you tray to make the special round more harden, something like the guys from renaissance mod did with the hellhounds round, they added special habilities to the hounds making the round something to be worry about. also if you can add some other perks will be awesome. i guess 8 perks are enoght. if you can add some special enemies after round 10 it will be other good feature.
I hope you made it, just take you time and thank you very much for doing this great map.
