first off I just wanna say this mod is insane and you made one of 12y/o me's zombies fantasies come true. I really love the new special enemy update and it's really cool to give maps certain combos. however I do have a couple suggestions going forward with this mod
for one having dedicated perk machines on every map would be really cool. each map could also have specific machines to cater more to having unique gameplay (i.e. nuketown has the main 4 available like the actual zm map, maps with more verticality have PHD available etc.)
The only other major thing I'd say is each map having their respective background score/music from mp just to have that added layer of flavoring to the map bc atm just having the ambient sounds gets boring after a while and it'd be nice to hear that music during quieter moments of gameplay. Other than that this mod is really sick
