Here's an amateur ASCII depiction of the scene as I believe it has been shaped, in case anyone else believes this is different:


	______________________		_________________________
	|		    Plane Entrance			|
	|		         [b]Void[/b]			|
	|							|
	|							|
	|							|
	|							|
	|                  -----------------			|
	|     Presumably, Deployable Barricades of some sort	|
	|		 [b]SOLDIER agents[/b]			|
	|							|
	|							|
	|							|
	|___________________	Entrance    ____________________|
			Purge		   Purge

				  __|__
				  \ | /
				   \|/
				    V
			    Shikaru's Bunch




EDIT: Due to the font used by the website, this does not function. Click 'view raw' to have it look like something that makes sense.
