Maybe new textures? The sound is fantastic as it is but the doors themselves dont look all that 'indestructible'. Adding more sturdier looking variants would be cool. :D

The doors were placeholders so new textures might come in a near future update.

Can you craft the doors and do you need the undergroung society thing for it? I'm trying to do it in a regular server and i can get the keycards, i just cant find how to make the doors?

Shouldn't one with enough electrical skill be able to make a sorta makeshift cracker device that can hack or brute force keycard recepticals, mainly using alot of scrap electronics and scrap metal to craft such.
