This miniature scatter terrain was designed for any tabletop RPG or wargame using 28mm or 15mm scale miniatures. You can find and hack the design here on TinkerCAD.
We've set up a Patreon page for anyone who's interested in helping to fund us so we can keep making free and open sourced games like Pocket-Tactics, Discord, and others, not to mention the growing catalog of gaming miniatures that you can use for whatever you want! (Psst... we take requests and commissions...)
The character model in the background is from Reaper Miniatures. If you want to play around with these parts in TinkerCAD (to easily make your own rock formations) you can find it here.
