I am currently working on the very first combine/citadel themed map. I am unsure where this will go as there is no set plan as of right now. I'm just creating certain elements and seeing how they can be implemented into the map. Below you can see 1 of the elements I've already made. It was initially just an experiment to see what I could do but since it turned out pretty cool I decided to use it. In the video it is missing the double helix staircase that winds around the plasma/lightning cylinder. This staircase can be seen in the pictures below.
