Impudent Mortal launched a Kickstarter campaign for a set of terrain in both 28mm and 15mm scales. They’ve already made their goal and then some, so it’s stretch goals for 26 days.
From the campaign:
In order to continue expanding our product line, we have decided to make industrial themed terrain that can be used across a wide range of gaming systems, but not only are we going to offer it in 28mm but 15mm as well!
As such, we have broken this Kickstarter into two different parts with specific information about each scale contained in its own section so you can check out exactly what you are interested in.
All Terrain comes unassembled and unpainted, figures are for scale purposes only and are not included.
The terrain pieces are made primarily from MDF (Medium Density Fiberboard). Additional details parts consist of Grayboard (very heavy duty pressed cardboard), Oilboard (a heavy duty paper, typically used in stencil making, that is flexible and takes paint well), Drinking Straws, Heavy Duty Cardboard Tubes, and Styrene Rods. All of which holds up great under the rigors of heavy gaming.
