This is a long suggestion but ah who cares
We need a warhead i get its a bunker but who cares you should add a warhead so if there is a big security breach you or the ambient npcs can, If the warhead is activated a bunker will be opened and the alarms will be yellow and then there is 3 minutes till detonation you can cancel it in the bunker control room and to activate it in the warhead room there is a switch that you flip that allows the warhead to be detonated then in the bunker control room you can activate it there and the bunker closes at the 1 minute mark and then there is a secondary evacuation point with a helicopter and it takes of at the 30 seconds till detonation mark after that if you take the secondary evacuation point the helicopter takes you back the the bunker and you can see what happened to the bunker like destroyed and things same with the bunker it opens and you can see what happened to the [Main bunker] Sorry for writing this long comment and maybe wasting your time if you dont add it.

can you survive the g bombs stuff in this?
if not maybe add ig support for mods liek that
so you can surrvive alot

Def not gbombs Maybe GWarheads or HBombs you can since Gbombs dosent really understand whats a wall and what isnt.
