This corebook does a great job of detailing both the 2d20 system used to play the game as well as the Fallout World the game takes place in. I'm only passingly familiar with the World having never played the video game (Although I have played the board game) and had no issues getting the feel of the Vaults and the Commonwealth as well as the adversaries both human and otherwise.

Various quests and plenty of background are included to give a GM dozens and dozens of gaming ideas to fuel a fertile mind. At the end of the book is included a more detailed adventure. This quest is a murder mystery that gives the players an opportunity to create new characters for a long campaign or have seasoned characters come upon a town during their travels.

As always with Modiphius products the art is top notch and goes far to give readers a visual feel for the game, which further helps GMs new to the world immerse PCs in it. All in all I consider this book well worth the price of admission!
