I saw this and was intrigued. Being new to Mothership, I have been looking for support materials for the game, and this does not disappoint. I love the idea of this turret system, and I like the adventure that is included. Good NPCs, excellent maps, new equipment, easy to find tables, and a quality hardback. Good stuff from a good company. Quick note: looking at the descriptions online, it might not be clear of what you are getting with the box sets, zines, etc. This book / resource is not really duplicated in the box set. The details of the adventure and additional material is in this. The basics of the turret system are reprinted in the box set. Honestly, I kind of like having the turret system booklet from the box set as a reference along with the hard cover of the adventure. It’s all good, you will probably want both.
