Damnation

Terra Verte has two boss fights.

The first boss is Dayden. Make sure you pick up pistol ammo on the way to the boss fight. On Insane her sniper / charged rail shot will kill you in one hit. I tried hiding in the building, on the building and running around. None of it seemed to work because of the one hit kill. By accident I fell off the edge (near where you start) and held on to the edge. When Dayden shoots at you it will hit the ground if you are just hanging. After the shot you have a few seconds to take pot shots at her with your pistol. Time your shots and make sure you avoid hers and she will be no problem to beat.

The second boss fight is against Selena again. Before you take the zip line down to COG #15 fill up on machine gun ammo and sniper ammo. Take the zip line down and run to the back of the lower building against the wall. Kill the robot if possible then take up position behind the metal pillars next to the wall - you can see the enemy better here and you are slightly protected. Heal Jack when she goes down and pick off any enemies you can - there are a lot. After you have cleared off the enemies it is time to face Selena. Run up the stairs in the middle and sprint past the openings to the Left. There is a window on the far Left of the platform with an additional sniper rifle next to it. If you stand next to the wall you can not hit Selena with the sniper. I tried to shoot her as she was walking away - she was facing away from me and as I stood up a shot from her spike gun shot out of the side of her head and killed me (stupid broken game). I found that if you are at the window crouched down and take a step or two back you can sight her up in the sniper scope and she will not see you. By stepping back you are able to shoot over the window wall and can kill her easily.

* Notes: As always take advantage of cover and use your spirit vision every time you enter a new area. Your partner is fairly helpful and will kill enemies over time - it does take a while sometimes though.
