The Laundry RPG 第二版: 主管指南

The section on running bureaucratic horror campaigns is exactly what I needed—it turns the whole "weird spy agency" premise into something playable and tense. I ran three sessions with it last month and my players were legitimately paranoid the whole time.

Really useful for running the game, especially the new section on handling sanity checks during play. The layout could be a bit clearer in a couple of spots, but the expanded threat stats are a big help.
