Here's a map for a scenario with a ruined highway overpass blocked with abandoned cars.
I did four different versions of this 28x40 square map with and without a grid (140 px/square).
A layered version with even more options to build your own scene is available for Hero and higher tier patrons , and a ready-to-play version for Foundry VTT will be available for Hero tier and higher patrons with the next module update before the end of the month.
Thank you for your support!
