La Legion Noir includes the typical Amnesia Gameplay like searching keys or exploring the environment.
You will start in your house but something is wrong here. You can hear voices and the facility behaves strangely. After a while you see that you don't have any chance so you must escape and go through the forest.
The special thing is that you have to explore a large outdoor area called "The Forest". But be careful because the evil can lurk behind every tree.
