I've seen this mentioned by a few others and I'd like to get an official statement on it. Hopefully I didn't overlook something or I'll feel really stupid
I can't find anything on monster manoeuvres. It says in another section that they do not suffer stress or fatigue, and if forced too take wounds instead. However, fatigue seems to be an important part of movement. If they are simply immune, then that leaves them wide open to over perform - you would have to rely on your GM to not exploit things (which shouldn't be a problem). If they are 'unable' to perform additional manoeuvres, that causes problems too, particularly with movement and things like swapping weapons, retreating, or interacting with the environment.
Without a little leeway for the beasties, I could see players walking into a house and shutting the door and thumbing their nose at monsters. It would be a total 'Big Bad Wolf' situation. He walks up one turn, opens the door the next, walks in the next. In the mean time, the players go into the next room and shut the door again. Repeat raspberries and monster taunting.
With too much leeway, a GM could get excited and over perform, for cinematic effect, and draw some ire from the players.
I understand the loose rule system for creativity and freedom, but I need something solid on this one
