Guide
Aim for the head, don't stop shooting because you don't have that much recoil and you have a lot of ammo (mostly more than enough for killing almost anyone by shooting on his head). Open the shield when he starts shooting at you.
Use OPPORTUNITY IN CHAOS when you can (you get it at level 12 Vivian)
