I've been working on a remake of Foundation for a little while now. I figured I would put this up although it's in it's earliest iteration. It's set up for Oddball, KOTH, CTF, Flood, and Infinity Slayer. When you play it on flood green room has a little alteration. Pics and Video are horrible quality. WARNING: VIDEO IS HORRIBLE QUALITY!

I gotta say, I really like your center structure design. (Probably the best I've seen yet, imo.) But, your use of glass walls is a little strange to me. I understand we don't have to worry so much about frame rate, but they still make the map feel more open than Foundation did, and I imagine they sorta break the illusion that there might be more to the map... Still looks good, and I imagine it would play well.
I had walls up around the map but it felt entirely too dark on the one side. I had to rebuild the outside walls a few time trying to make them look clean but the shadows kept ruining the one side of the map so I said screw it and went with glass walls. It really bothered me to do it but the lighting system made me do it. I also had a little thing on top of the map like the original map but it casted such an ugly shadow I decided to do away with it.
This map is spectacular. The first Foundation remake that actually keeps the proper scale of the main ring
