San Diablos

San Diablos is a horror time-trial game in which you play as a detective-exorcist in a city that is always dark. At your boss’s behest, you have 60 minutes to perform exorcisms in three locations before you suffer the consequences.

You travel around the city to find areas that need exorcising, then fight different kinds of monsters in first person as you try to clear each area before time runs out. There are no save states and no second chances. The game is closer to a tech demo than a full-fledged game.
