Weird Westerns can be hard to do without being samey. Dark Trails sets itself apart from the pack by doing many things differently and well. Each character class looks, feels, and plays differently. From the more mundane classes one would expect from a western setting to the more fanciful and thematic. The influences for the system are deeply rooted in pulp westerns, gindhouse schlock, and lovecraftian horror.
To make things even better, Dark Trails runs on the Dungeon Crawl Classics system. The system is well suited for fast and deadly play. If you are familiar with DCC, there are some new mechanics to learn. The Hex and boon token system is well done and the gun deck adds some more random fun to simulate how unpredictable guns could be during the 1800's.
The book is well organized and the main topics are separated in neat and tidy chapters and it is very readable. The art is varied and of great quality. The included scenario is lengthy and well written, it serves its purpose of showing the would be judge how to write and structure scenarios for the game. There is just enough info here to get started playing without ruining excitement for the complete book that is coming. Even after the release of the core book, this will still be a valuable resource to have available as it is very easy to parse the mechanics quickly!
