As a standalone product this will be a great buy. Though as a Fate book, not so much. More than an actual new Fate book, it is a merger of several other books, where the text is more or less lifted directly from those books. Most of the DnD parts are actually from the Fate Freeport companion, it includes the most important parts of Fate Adversary Toolkit as well as the Fate core rules. There are aslo some extra rules from War of Ashes. While this is a great combo, it doesn't really add much new to Fate. As a fantasy version or DnD version of Fate, it doesn't really add much. The Freeport Companion adds monsters, a setting and characters, as well as most of the rules in this book. Dungeons of Fate is a quick and dirty version (one page) that allows you to mostly the same as this game. Aperitana Arcana, while not my favourite, adds original material and rules.The online Pathfinder Fate Accelerated conversion adds loads of details with example stunts and ways to play different character classes. And then there's Fate System Toolkit and Adversary Toolkit.

So if you want to play Fate in a DnD world, and don't own Freeport Companion, Fate Adversary Toolkit and Fate Core, buy this book. If you are a Fate player looking for good resources on how to play DnD fantasy with Fate, you don't really need this book.

Though, if they add a Bestiary (there's two monsters in the book now), and some more on how to play classic classes of DnD (ie. suggested stunts and aspects for a Warrior, Rogue, etc), this Fate hack would be worth the money.

Crashing Beasts & Crumbling Halls is a delightful dungeon-delving fantasy that leverages the mechanical strength of the Fate Condensed system to deliver an exciting and narrative-driven experience to players. There is a level of thoughtfulness and care that can be seen in the design of it's systems and writing that shows a both a deep love for the genre and expertise in it's craft.

Goregous layout with full illustration that sets the tone for the game well. Rules are concise and quick to pick up for folks familiar with popular dungeon-delving fantasy RPGs or other FATE-powered games.
