Best free "dark, gothic" games

Demons from the underworld, vampires resting in coffins, noir murder mysteries—these are all themes steeped in dark and gothic atmosphere. Many games draw inspiration from such gloomy settings, often reflected in their stark black-and-white palettes (with a splash of red… for the blood, naturally). So, what’s your pick? A horror-themed adventure? A bleak sci-fi tale? A moody detective story? The shadows are waiting—choose your poison.
