SCP: Darkwater

Inspired by the nightmare of SCP-1128, SCP: Darkwater is a psychological horror game that begins in the quiet confinement of a bathroom and descends into the terrifying depths of a dark, endless ocean.

You play as a young woman in her early 20s who wakes up trapped in a strange loop. Your only way forward is to fill the bathtub, submerge yourself, and cross over into a hostile aquatic dimension. But you are not alone in the deep. An enormous, primeval sea predator—the Ocean Horror—stalks the dark water, waiting for you to dive too deep.
