Well, I spent a long time working on this. I hope it'll be nice. I, unfortunately, I don't remember everything I did. I remember (hopefully) most, though.
-Added a bunch of pillar things
-Fixed the weird looking wall w/ a metal roof/wall, but the other visible wall was concrete
-Added a couple of varying height stuff
-Made the floor of the point into glass
-Got rid of that one "tunnel" in the battlements roof by connecting the wall
-Made the battlements roof look nicer
-Optimized the map more
-Changed all the tiled outdoor concrete to the non-tiled concrete
-Added a neat "storage" area under the point
-Put a doorway in the "underground" room for slightly more sightlines and not being forced to give up high ground to pass
-Changed the white metal textures to dark grey metal
-Put railings on the point roof
-Gave indoor areas floors
-Hopefully made the point cap zone more visible
-Changed some textures to metal for more a TF2-like feel and more realism (nobody has 50,000 sq. ft. of concrete)
-Moved some spectator cameras to give an actual view
-Raised the skybox by 64hu
-Removed the metal panels on the point roof
-Made the doors to the tiny buildings bigger
-Put metal fences on the walls to surround the map.
-Made the walls on BLU and RED side have neat metal textures lining the bottom
-Improved clipping
-Fixed some overlays not appearing
-Did another artpass for some de-squaring of detailing (hopefully)
-Made the metal floor things taller and larger
-Hopefully fixed a weird issue w/ cap cubemaps
-Reduced the numportal count by 700 (not to your computer's detriment)
