Pecaminosa is a top-down action role-playing game with a noir-inspired pixel-art style, set in a crime-ridden city of gangsters, gambling and corruption. Players follow a detective investigating the city's underworld through dialogue, exploration and gunfights.

Combat mixes shooting and melee with character progression, while the story leans heavily into classic noir atmosphere, jazzy mood and shady characters. It appeals to fans of action RPGs who enjoy a strong crime-fiction flavor.
