I played SWAT on here a while back. It turns out that it's not the best SWAT map in the world, but it's still a solid map to be sure. The Derelict style layout worked nicely for the most part. There were a few issues I had, however. The bottom level of the map is, essentially, entirely flat. There's a few humps to break up line of sight, but that's it. I would consider these humps to be a form of lazy cover, and all of this made fights on the ground floor extremely uninteresting. The upper level as well, mostly being based around the same height, made for some rather uninteresting fights from a vertical standpoint. There just wasn't much depth to the combat, and it became rather predictable. I'm not quite sure what the best solution to all of this would be, as these along with some awkward segmentation are things built into the Derelict style design. I do like what you've done with the Green and Orange(?) corners (I think those were different when i played it), and I think that those areas help with the otherwise somewhat lacking segmentation on the map. I think that breaking up the height of certain areas throughout the map to create more height variation would go a long way towards improving the map as well.
As a disclaimer, I've only played the map once. It was a while ago, and it was on a game type which didn't suit the map particularly well. This is just what I remembered from that one game. Still, I think there must be at least some validity in what I've stated above. Hopefully I'll get to play this again before long.
