Landing Bay (2008)
The little things on the four corners of the landing bay are, of course, forcefield generators. I developed a hyper-secure entrance that I also used on the 2008 Fortress. It's a giant block that slides back, creating an opening up into which people or things can go up some sort of elevator platform, or a ladder, as this version has. I figured it would be much more secure, if a bit more inconvenient to use, than a traditional door entrance.
