The '''Combine Security Door''' is a type of door used by the Combine to block the three original Overwatch Nexus doors during Combine occupation of Earth.


The Dropgate is simply a large chunk of Combine metal that instantly drops on command along two large rails, in a manner similar to that of a WikipediaGuillotine|guillotine. It is unknown how the Combine actually make it drop, as there seems to be no switch to do so.

==Behind the scenes==

The three doors are http// brushes using the entity "http// func_door", named "atrium_securitydoors", hence the name.
