they were'nt kidding when they said this battle will last for hours. that was a crazy ass fight, all i know was it took forever to beat that old fart. i was using the tranq gun, its hard enough to find the old fart, yet he keeps healing his stamina bar on me, i tought i was gonna go crazy :frust. eventually i manage to figure out how to beat him. if i had to guess it probably took me an hour and twenty minutes to beat him, i got his sniper rifle after i beat him.
