Beat me to it!
If you aren't going to make the buildings look different with bricks, at least paint them different colors. Also, you need at least 2 crumbling buildings.
im going to add a building that has a fighter jet smashed into it(or a passenger plane) and the building right by it crumbling.what side should i put the fire excape on and how could i event it where they have to wait somehow untill they can get down?I added a turet,some boxes,and a stand with CEDA boxes by it.The top is going to be a little evac. center that shut down.
