(This review is for a print-on-demand copy of the book)
CONTENT - A solid set of four battle scenarios for four 4th level D&D 3.5 characters, set in the Underdark, and usable with both the RPG and the D&D Miniatures game. There's a small amount of background information and lore provided for each of the scenarios, and adventure hooks and further adventure suggestions for each of them as well. The NPCs are fleshed out well (Amandrucul is particularly nasty), and color text is well written. While it is short (17 pages), this product could open up a lot of opportunities for further adventures in the Underdark.
PRINT - The print-on-demand product is very good looking - the color cover is vibrant and not grainy, and the printing and artwork on the interior pages is clear even with the gray background graphics. The only issue with the print edition is the color maps, which look great, but do not come out to the proper scale for miniature use, and the binding prevents making color copies to scale up to the correct size. I'd recommend getting the PDF/print bundle and printing the map pages at a bigger scale in order to use them.
