I am evidently an *******. I was doing a run on Pike's near Hennigan's, when I saw a guy riding a horse. I wanted the horse, so I shot him off it. I then decided I did not want the horse. He respawns, pissed, and shoots at me. Me being a sniper, kill him before he even gets a shot on me. He respawns AGAIN, and I shoot him again. I then leave him alone.
We clear out this canyon to get the weapon crates. I am on the second one, so I kill all the bad guys and he arms the crate. Finish that and move on to the last. I take out most of the enemies, and he is running for the crate. No. I shoot him in the back of the head when he gets to the crate and starts planting. I quickly plant the explosives before he respawns, net the extra XP, then run off while he handles reinforcements. He hunts me again, and I think he killed me for the first time. I shoot him two more times, then run off.
I LOVE this game.
