Obscurium
Premise via IGDB
You open your eyes to blur and shadow. You're standing in a stinking morgue, in a tent hospital on the grounds of a crumbling French mansion. World War I rages on the far side of the woods. You can still hear the shelling over no man's land...
Obscurium is a 3rd-person point-and-click adventure. You guide the protagonist, Red Cross Nurse Mary Wellsley, as she explores rooms collecting items and solving simple puzzles. All the while she unravels the mystery of this bizarre place and the fate of her fellow nurse and closest friend, Nancy.
