I'm a fan of World Works Games. The products are wonderfully detailed and evocative of a mood perfect for the environment they strive to represent. Like Himmelveil Streets, this product has great flexibility and could easily simulate a dungeon or old temple environment or even a grim castle halls. A little work gives you instant payoff for a quick battle, but more work gives even better results and works with what you already made. I look forward to more sets, maybe even some retro-fits for earlier WWG products!

This set features the TerrainLinX System, which brings a new take on modular design. The modularity does not only involve a simple and effective method to interlink the base tiles, but also a system by which wall sections can be assembled in a dazzling variety of modes, including multi-leveled structures.
Obviously the walls (wall sections and wall posts) combine to the base tiles (via anchors), bringing the whole to a very sturdy result - way tougher than anythins seen before.

The set does not only features elements involving a sewer system - a great variety of tiles with sewage disposal canals and wall sections with outflows and other unpleasant... "decorations" - but also tiles without sewer-specific elements and similar walls. Moreover, railing and balconies for upper stories linking and sections overhanging the lower levels add a nice level of extra detail and possibilities.

The set could be used to build a sewer system for an old city, but also a generic dungeon or even a ruined and deserted urban landscape just by using the tiles without sewage canals).
With a bit of creativity, there are many more opportunities, thanks to the excellent modularity and texturing detail of the single elements.

The non-PDF files are for automated cutting support accessories (Robocraft, SilhoutteSD), and anyone without these does not miss any element from this set.

Not all the files are pdf and the result is that they are not able to be used for a wide variety of users. I had to fight to get the file to download right and now I find that only part of them are able to be used and viewed. I am very upset at what appears to be a tremendous waste of my money.

[Note to Cody4us from WorldWorks Games: On the issue of GSD files, just so its clear, you aren't missing any usable files within the product. There is a section in the product covering automated cutting (see page #15 of the instructions under "Automated Cutting"). The extra files you are seeing are known as "GSD" files. These files allow CraftRobo & Silhouette SD automated cutting machines to cut every page within the product automatically.]

Sorry I realized that after the above writer pointed it out. The product is great, I LOVE IT!!!!
