The Sixth Sin

The Sixth Sin is a first-person psychological survival horror game. In 1996, thirty-two children died in one night at St. Adela's Orphanage on Blackmoor Hill. Thirty years later, the player returns to the orphanage carrying a box left by the only adult who survived that night. The game features a grid-based inventory where items have shapes and can be rotated, an ultraviolet flashlight mode as the only means of harming certain spirits, puzzles solved in the environment without a pause menu, hand-drawn ritual sequences, mirrors that act as passages, and a radio voice whose guidance the player chooses whether to trust.
