So I was going back through the FAQ just to refresh myself on all the rules and now all Grey Knight Land Raider's and Crusaders have the machine spirit which allows it to shoot one more gun than would be allowed. After rereading that and going back to the Codex I noticed that the Crusader states that the hurricane pattern bolter can always shoot no matter the circumstances.
So my question is with the machine spirit on a crusader you get one more gun then would be allowed does that allow you to shoot the hurricane pattern bolter and another weapon effectively always allowing me to shoot two guns no matter the circumstances or is it that I can only shoot the two guns regardless of how far I move, but if i get a crew shaken I can only shoot one gun?
