First screenie from Descent, level 3

While level 2 is in Beta testing I have begun work on level 3 of the project. The first screenie can be seen at http://www.doomwadstation.suhost.com/main/enter.html under the news items. You really can't miss it. :-)
I am designing this particular wad with what looks like will be extensive use of bridges (including those you can walk over and under).
I have several ideas on the use of bridges in this level but their practicality remains to be seen.

I put up a new pic in the same place showing a little bit more of what I'm trying to accomplish in this level. Unfortunately it only runs well on ports. I keep getting HOM'S in vanilla doom2.
