Just want to share my progress on my Necromunda Zone Mortalis board with you. I recently finished the first tile - the Delta Anabathrum Complex. The idea is to re-create the 2D Necromunda tiles in 3D.
The duct in the middle (it's a loooong way down there) got cut out with a working tool (don't really know what it is, but it's best described as literal vibro blade). The bridge is made from plastic-card aswell as a Necromunda barricade.
Work on some more tiles has already started - here is a little teaser:
Last but not least, I fixed the GW plastic doors with cutting, and experimented with 3D ductways using magnets (rulewise you set them up and gangers can walk and shoot through it):
Hope you like, and stay tuned for more Zone Mortalis progress over the next weeks :)
