During the opening sequence don’t worry about getting shot. Your objective is to help the girl at whatever cost. You must get close in order to do that.
Chasing the girl in the white cloak:
When chasing the girl in the white cloak, there will be several hot spots in the woods. Whenever a hot spot appears on a log or a piece of wood, use it. To do this you must fight off the king’s men and escape several times.
The Amazons strategy:
You must take down your opponent multiple times and recover by evading the attacks when your strength is low. Watch your energy meter and stop swinging when you are low. Look for the throws and duck while recovering.
