From publisher blurb: Explorer: Mine Complex is a set of printable battlemaps compatible with any RPG/Dungeon-Crawl game. Explorer: Mine Complex is a standalone set, comprising five 30x30 battlemaps. Each tile depicts a length of mine tunnels and networks. Whilst each tile works perfectly well on its own, they can also be joined together (in sequence) to make a long stretch of mines to explore. Please Note: These maps are not geomorphic, but can seamlessly join together in a line (Maps 1,2,3,4,5 )
