The Maniac

From BoardGameGeek:

The Maniac is a hidden movement horror board game in which you will have to survive the murderous rampage of a psychopath, but you could also be the murderous Maniac! A group of college students decide to reopen the old Black Pine Lodge in the mountains of Crystal Country. A place closed several times due to various misfortunes that have occurred over the years, but as soon as they arrive they realize that the place actually seems contaminated by something ancient and evil. They decide to explore the place, but it will only be when one of them finds a cursed mask that the real nightmare will begin! In The Maniac at the beginning of the game everyone is a "Survivor" but the real game begins when one of them finds the cursed mask. From that moment on he will become "The Maniac" and will have the goal of eliminating everyone else. The Survivors instead will have to try to escape from Black Pine Lodge by activating one or more endings. The Maniac is a hidden movement game where no one will ever know exactly where the other is. -description from publisher
