From publisher blurb:
Modular Kit: Sewer Hideout 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 Hideout comprises 2 rooms that would be the ideal location for thieves, smugglers or anyone else that has cause to hide in the sewers. One room serves as a dock and warehouse, full of crates and barrels near a small boat. The other room contains two simple beds, some chests and a table where a game of cards is in session.
Also included:
A set of 300dpi full size png files, for poster printing or VTT.
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)
