This may have been mentioned already, but I missed it so though it would be handy to point it out.
Barrel Roll
"If a player declares a barrel roll action for his ship and cannot complete the action in the desired direction, he may choose a different direction or a different action entirely."
Boost
"If a player declares a boost action for his ship and cannot complete the action using the desired direction, he may choose a different direction or a different action entirely."
So how many people (like me) assumed they knew the rules in the new rulebook already?
