Security has a badge scanner system that can be toggled on and off, Green means crew with a valid ID can enter the armory by using the button on the door, Red means access is only by Captain and Security by the door itself, this can be toggled on/off inside the armory in case someone gets stuck inside doing repairs/nefarious deeds.

Lots of tiny and low impact features across the board. Added new duct blocks in Engine 1 and Gunnery Upper, Changed duct above Medbay to drain into Gunnery Lower.

Sonar Monitor room has quick glance info on sub position so you can check depth/speed/distance to inform divers and crew.

Lots of small cosmetic details, didn't go crazy.

Expanded some storage, bar acts as a medium cabinet so you can store snacks or various loot, giving you reasons other than RP to hang in the lounge area.

Fixed Berilia 2.0 periscope bug by reset to prefab so they don't display a info window of signal out.
