Werewolf: The Apocalypse - Earthblood

In this video guide I will show you how to stealth kill 2 Fomori. This option won't be available until mid game. Once you return to Washington State Forest for the fourth time you will be tasked to kill the creature. Which is a fomori. Use the LB button to detect them when they are in human form. They will have a distinctive purple glow on them. Just stealth kill them like a normal person two times and the achievement will pop. I wasn't able to get any real good stealth kills on them until I got to the Nevada Desert. There are plenty of opportunities there.
