Sniper elite 4 Abrunza Monastery Authentic Plus difficulty without taking any damage

One of the toughest missions to run without taking any damage. You can stealth through the first area to the two storey building below Castle Hill, but the enemies in the courtyard area will track into the second area... Once they do it's difficult to remain in cover as they fire from all sides. They also fire at you from the rooftops behind you! I managed to clear Castle Hill from two storey building but usually there will be enemies holed up near the big gun - they can be lured out with stone throws or hoy grenades down at them from the ramparts :) Even after Castle Hill is cleared there will still be enemies about - and you can still be killed inside the castle after completing the objective! After entering the Monastery proper, Capo patrols a circular route around the grounds.... Sometimes he'll be right there when you enter (I just missed him).... But if he's not lay traps just outside the door and wait it out till his payroll brings him back round again... I had to wait 22 minutes for him to return, so clipped the footage to keep the recording under 1 hour.
