well, When i began running to the high ground, I had a total of 20 shots in my fully upgraded P8. so **** him in his back while he was coming up the ramp till he went after shiva, she wasted all her ammo covering me, then I covered her shooting whenever i had a clear shot at his weak spots, then after i moved the rock, i used up the rest of my shots on his weak spots, and finished by literally Stabbing him in the back till it let me grab him, and sheva ran up and did some karate kid **** to him.
