Nice work on the map! Really enjoying the nostalgia factor, and the flow and layout of the map lends itself nicely to the pace of DA. As far as suggestions/complaints go, I personally would like to see the outdoor area get the axe. While it can be useful at times and provides nice access to the upper levels of the main map structures, the outdoor section feels almost like you've gone outside the bounds of the actual map. In fact the first time I played I thought I had clipped outside the playable area when I got to the outside portion.
I've also noticed that something in the maps brushes/textures is causing texture errors for me on all weapons, including those held by other players. Guessing this could be a result of the decompile. Other than that, keep up the good work man
