Thanks for taking your time and giving some nice feedback.
Having two weapons active is a sorta know bug, if you want to break the weapon system it's not that hard actually, so I'll work on that.
The skull powerup is NOT INSTA KILL, it's quad damage, but since a lot of people think it's insta kill I'll probably just make it insta kill.
Getting the Upgrade station to work will definitely be more difficult in the next map, for sure.
The reason for even modeling the radios was exactly like you said - lore. But I decided to not rush adding lore in this update, It's kind of hard to think of anything interesting that can be conveyed via a radio.
