Red Reality

Robert Scranton is a researcher who accidentally fell into the hypothetical paradoxical "non-dimensional" parallel space of SCP-3001. Although SCP-3001 is considered an infinitely extendable parallel universe, it is virtually devoid of matter. You will experience the feeling of desperation in the game, and the suffocating feeling of despair when he is alone. 

Most of the game is spent listening to the protagonist's voice, hissing in despair. 

All the voices in the game are audio from the Youtube channel ForlornFoundry: The Foundation: SCP 3001 - Red Reality (feat. GemoDawn) (youtube.com)
