A question about the first scenario (The Bedlam Affair / The Heist): how are the buildings (bank and others) supposed to work here? Can you enter them? What happens if you do?
That's left up to you and your terrain. If you want them to be accessible, I recommend using "off-table" grid maps for the interior. Heroclix maps work very well too. If you enter the bank prior to one or both of the villains (Bruiser Benning and / or Tonalli) make their exit, you can carry the fight to them in there.
Hope that helps!
