Mission 3
========= 
Igor 

Search the bookcases. The third one from the left will fall away to 
reveal a secret door. Head through it, and go along the corridor. 
Blast the zombies when they appear and head on, through a circular 
room with more zombies. You'll find another door that can be blasted 
with the shotgun, revealing a cheat! Carry on along the corridor, up 
the stairs and through the door, blasting more zombies with the 
shotgun en route. Grab the crossbow at the top of the stairs and use 
it to kill the possessed owls that attack at the top of the stairs. 
When they are dead, approach the statue and shoot it with the 
crossbow to open the gates, On top of the nearby building, grab the 
life replenishes and ammo replenishes, then head through those gates. 
In the next area, fire and roll to kill the wraiths that attack, then 
follow the stream to the next section. The dragons that attack here 
cannot be killed with the crossbow, so switch to shotguns for maximum 
effect! When you can, use your grapple to climb up near the waterfall 
(you'll be attacked by more dragons) and then across to the far side. 
In the next area, kill the wraiths with your crossbow, then jump up 
to the platform. Use your hand weapon to knock the statue over and 
bridge to the next section. Here, use your shotgun to dispatch the 
assorted enemies, making sure to jump and roll as much as possible. 
That done, leap up to the platform and use your grapple to find 
another cheat! Head up to the top of the waterfall and around to 
confront Igor
 
Igor 
====
Igor attacks by throwing fireballs from the perimeter of the 
courtyard and has the ability to disappear and reappear in a 
different location. Train your sights on him straight away using the 
R1 button and fire away using the crossbow to cause him damage. When 
he attacks with his fireballs, roll away from the areas he is aiming 
at and get some more crossbow shots off to exact your revenge! Before 
long, Igor should bite the dust and worry you no more! If you are 
really struggling, grab the speed boost from the barrels by the gate, 
but you can beat Igor without it.
