Fighting the big ugly boss in Deus Ex: Mankind Divided

Viktor Marchenko is a particularly nasty boss in Deus Ex: Mankind Divided. He’s built like a tank, and he’s a bullet sponge. No matter how many times you shoot him with a sniper rifle in the head, he comes back. But you have to take him down if you want to get to the ending of the game.

Before you get to Marchenko, you have to make a choice. You either rescue some people, or stop Marchenko
