From publisher blurb:
The Mines series introduces a new rough-hewn look to Dungeons in Blue geomorphs. Each tile in this collection depicts corridors and rooms suitable for use in a mine or an area of new construction. The set also includes transition tiles that link this rough style to other connection types. The Mines #2 contains 16 tiles, and it will be included in the upcoming Mines Triple Pack.
The Dungeons in Blue series brings classic blue maps to the virtual tabletop! These ready-to-fill maps are packed with rooms, corridors, pits, and caves; all judiciously sprinkled with tricks and traps. Every geomorph tile seamlessly connects to every other tile in the series, providing the megadungeon builder tremendous freedom and flexibility.
This product includes sixteen unique map tiles rendered at 100px per five-foot square. The set includes two versions of each tile, one for players, and one for GMs. The GM's version shows additional features, tricks, and traps. This set includes (MI17-MI32):
Four 100x100 foot tiles.
Eight 50x100 foot tiles.
Four 50x50 foot tiles.
A map legend image detailing all map markup.
A one-third scale summary map showing all tiles.
A short readme PDF.
All maps are ready-to-use PNG-format files compatible with most virtual tabletops. Use them as-is, or combine them into larger maps using your favorite image processing software.
