I had a run around this one - it's kinda like an UT level in places. Way too dark down some corridors too.
Overall, it's a pretty cool looking map, but I'm not sure it'd be all that fun to play - some poor clipping means it's too easy to get trapped. I also feel it's too large to be all that fun to play - it's too slow to navigate and I don't think you'd encounter other players that much.
