Very Nice & Modern At @Elevator to underground - ETUG! 

This map was detailed and too many buttons to play with, from air con to shaft fans systems. (Some air shaft duct may lead to outside the map) A lots of features that I think would be like a core protect or meltdown games or something similar cause it have chiller and boiller that would updates in the future. And electrical components to create blackout and generators, A good shader, texture and ambient lighting aslo audio. I personally ❤ Elevator. And yet Gas are uique.

This is a cool game

Is there a hotel? Or a bedroom or house?

The amount time spent on the making on this game should be very high in hour
