Kill The End before the actual boss battle
As you come out of the dark ass cave after fighting ocelot there will be a movie seen with The Fear pushing The End out of the warehouse. Before this happens,look for an alternate route and you will come across a building. Search the building and the area around it for a sniper rifle(Dragonov. After finding the rifle go to the movie scene, as it ends two guards will begin to push The End inside shoot them both (headshots make it easier) then shoot The End in the head multiple times just in case. Walah no boss battle!
