So this set bumps up tight to the other if you want and gives more width. The back wall is movable removable. and there are a bunch of props that can be mixed and match with other sets or whatever. There's not a sewer but enough of a whole to make it believable.
Oh this will be useful, just for the flying debris props alone. But the option to build a longer wall with multiples is great, too! Can't wait to get my hands on 'em! On that note, I still haven't seen a scene in DAZ or Poser with a steel girder and/or Lamp post (in both undamaged and after getting used as a club forms). That would be neat for a future installment in these sets
