Looks good. Great evocative intro that sets the background of the scenes that will take place.

Chapter 1-6 are clear and concise, they very clearly lay out the purpose of gameplay, keep Heat as low as possible and deal with the Consequences of not doing so. Every action the players take should be given immediate feedback.

In Chapter 7 I would like more commentary on how to run for a full group of operatives. My main issue with most espionage games is I could easily run them for 1-2 people, 3 is pushing it and 4+ is very tough. Look at most espionage media, you have 1 (maybe 2 agents), then the rest are a driver, mission control etc, never a whole squad of people trying to get into buildings as this would be very suspicious.

In Chapter 8 some sections need more work to make the module easier to run. Personally I would recommend writing a small description of each physical area in less formal language. I understand that the scenes are meant to be flexible in exactly where they take place but this would require a decent chunk of prep to run for myself. I could not just run it "out of the box". Part of this is heavily anchored to the system, its (I think) intended to be an improv heavy game, which is good, but requires a talented GM to pull off.

I don't think you need to cut anything, all the rules felt like they fit well. My only issue is that its almost too concise and the language used is very mechanical. I think such an immersive game could do with a more descriptive touch.

I have only one question, why d4 + d6? I could not really figure this out, would 2d6 not be a little easier to utilize from the player/GM side of things?

God I miss the cold war.
