1. A player character or NPC changes facing during combat, either turns sideways 90 degrees or turns totally around 180 degrees. Does this cost a half action, or is it a free action?
2. A PC or NPC is standing just around a corner with his gun drawn and ready. He puts his head and arm around the corner in order to shoot the people he/she hears approaching. Does this cost a half action or is it a free action?
