Heroic Maps knows sometimes your characters end up in rather unpleasant places and so has created their new modular sewer terrain kit.
Smells like poogas.
From the release:
Modular Kit: Sewer Large Rooms
Modular Kit: Sewer Large Rooms 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: Sewer Large Rooms comprises 10 different rooms that can be printed multiple times and arranged in limitless combinations, combined with the Sewer set to make huge sprawling sewer systems
A set of 300dpi full size png files, for poster printing or VTT.
A sheet of wall texture, for custom wall layouts
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)
