I've been messing around with the layout of tyr_dm5 (I'll call it that for now 'coz I get sick of writing 'my next DM map') and came to the decision that the layout needs to be completely rebuilt. This is not as much of a setback as you might think though since I already have the texture set, architectural details and general theme nailed down.
I'm going to be away for the next five or so days, so I'll hold off on posting the next set of SP screenies until I get back. This map will be every bit worth the wait - I'm looking forward to playing the finished version myself!
