Well I've got some modern and Sci-Fi games I'm working on and I really wanted to do some game in some underground complexes. What I decided to do was make the basic set as simple as I could make it and also make it modular. By keeping it simple I can dress it up however I like and by making it modular I can get maximum flexibility out of it.
Here's what I came up with. This seven room complex is constructed from one 20x30 inch sheet of black foamcore. The basic complex after construction. I will be painting everything grey inside and outside the rooms. The hallway is just one 2 inch wide strip of foamcore and the end of the hallway is just a simple 2x2 inch square with a 1x2 inch rectangle glued to the back of it to hold it up.
The doorways are all 1x1.5 inch which is large enough to fit the average 28mm figure on a Games Workshop round infantry base. Of course figures with larger bases or exaggerated poses won't fit but it's easy enough to just set them on the other side of the door if need be.
And this is basically all I needed to put the complex together. A ruler; pencil, ex-acto knives, tacky glue. That's also all the foamcore I had left over.
These next two pictures show two different combinations. Keep in mind making new hallways is as simple as cutting 2 inch strips of foamcore.
I think I'm going to try to add to this complex 1 sheet of foamcore at a time. The sheets only cost a little less than $4.00 and perhaps another couple dollars worth of materials. Heck even if you didn't have anything to do this project with you could probably get all the materials and tools for less than $20.00.
Next update will be basic painting.
