Also known as Victi, Vigil
is a different sort of adventure game suitable only for mature audiences. The subject matter is questionable, and some of the scenes are mildly disturbing even when much of the story is shrouded in mystery.
The demo showcases quite a bit of gameplay, in which all movements and interactions can be controlled using the mouse. Left click on a destination to make Dehon run towards it, and right click when standing on a correct spot to wave your hand or chant a prayer. Rather useful in activating objects or opening doors.
Perhaps best described as Sin City meets Killer 7. The trial version
is available from GarageGames as well.
