Clea is a free survival horror game with more limited use of darkness, and no jump scares, compared to other entries into the genre. It follows Clea and her brother in tow as they escape from their family and their family's mansion. Dark magical secrets surround them, and some of the game and its lore is optional. The player's choices will affect the ending of the game, making it less linear than many contemporary titles with similar game mechanics and story lines.
