Nope.  No life in the city he is describing.  What he means is, everything is dead.  NO life whatso ever.  As bleak and horrible as one can imaging.  I know what he is talking about.  I have the movie.  Umm...  There should be a ruined building in the free stuff, though if you want some rusted out hulks for cars, may I suggest getting the cars somewhere, or some other vehicle, and using a rust texture on them.  Take out the windows if you can, and flip them over or lay them on their sides.  

As for the windows... well...  good luck with that, unless you want to manually boleen them to pieces.  Not a good idea though.  Other than that, I have no suggestions.  Good luck.  I look forwards to seeing your work.

PS.  One last note before I post.  One thing I found that helps with layers in Bryce, if you arn't too skilled just yet, is to group an object, make a copy of it, then once that is done, go into the atributes area, and make it smaller by two or three points.  IE, if it was 120.45 before, make it 119.45 after.  This makes things smaller, so that you can make the bigger one your damage or rust or whatnot and add another layer of corrosion to it, by making the large one somewhat see through.  

Make sense?

In order to go forward, one must often times look to the past.
