get a rocket launcher and when he starts running at u shoot him. if his wing is gaurding him it won't hurt him at all.

thro a had grenade at him, when he's on his knee, then shoot him with the launcher...

just shoot his leg using a magnum gun!

try prl 142

Firstly grab a lot, and I mean a lot, healing items. Go to the tower and dodge his attack in the cut scene. Now, the battle begins. Grab you knife and wait for him to come near. When he tries to attack, slash. Dodge all of his attacks, especially the one where you're lying down 'cause that's one hit kill. Rinse and repeat till he dies.

It's easy just shoot his leg with striker,killer 7 or broken butterfly and when his whatever it's name is down slay him with your knife a view time and his going down.
(Note:if u don't have any of that weapon u need to shoot his leg for a view time with handgun).

Alright.

TMP. That's all you need, unless you ran out of bulletts.

Shoot at his feet, dodge when needed.
