I haven't reviewed anything by Lord Zsezse Works in a while, partly courtesy of having reviewed stuff from them pretty regularly and always giving it good reviews. However, it's been a good while since I first reviewed their stuff, and to be honest, I wanted to see how they had progressed. Oh boy, have they ever! (Not that their earlier stuff was bad, but this is stellar!)
There's a lot of utility in this product. There are truly high-resolution maps that should be compatible with any digital tabletop software (8200x8400 pixels!). There's an isometric view that brings back memories of such games as Baldur's Gate or Icewind Dale. The art is top notch, and the PDF file for printing uses a layer system to allow toggling of grids, to allow printing with or without grids.
If you need a map for an ancient prison for use in a campaign, or you have a campaign that could possibly run into a prison or something along those lines, I'd recommend this map wholeheartedly.
