Underground Labortory for Teardown

I build an underground Base with an elevator and a few Minecraft Zombies and Creepers. In the Laboratory are NPC's and a few rooms like a meeting room, storage and Laboratory. I coded my own door system, alarm system and door by Button system. Under the underground laboratory is a Bunker which isn't finished(I am still working on it.). On the Map there is also a Warehouse for the elevator company, an hospital and greenscreen and above the Laboratory is a house.
