From publisher blurb:
Modular Kit: Mine Chambers is a printable dungeon tileset compatible with any RPG/Dungeon-Crawl game. It can be used as a standalone set, or combined with any same-scale tileset.
Modular Kit: Mine Chambers comprises 2 x10 different tiles that can be printed multiple times and arranged in limitless combinations, and combined with maps from the Modular Mine Tunnels & Modular Caves set.
The set includes 2 variants of each chamber - Gold Mine and Crystal Mine
Included:
PDF printable sheets, with both gridded and non-gridded versions
A set of 300dpi full size png files, for poster printing or VTT.
n.b Whilst the file size seems large, each variant is a separate file, so you don't need to download everything
This set is compatible with the 2.5D crafting system, a crafting technique for making dungeon tiles more than 2D but not quite 3D. The 2.5D system was created by DM Scotty (Google his forum for tips)
