About Site Unknown
A first-person horror exploration game set within a secret research facility hidden on a remote island.
After mysteriously waking up inside an abandoned laboratory complex, you quickly realise something has gone terribly wrong. The once-active facility now sits in silence, with damaged equipment, locked research areas, scattered documents, and signs of a rushed evacuation left behind. With no idea how you arrived there, your only option is to explore the facility, discover the truth, and survive whatever still remains on the island.
Progress through the laboratories and surrounding areas, you will search for access cards, unlock restricted sectors, complete objectives, and find hidden information through documents and storytelling. Every area of the island reveals more about the experiments conducted there and the events that led to the research operation's downfall.
This is what you must uncover, and the more places you explore, the more secrets of the island will be revealed. You will uncover unusual experiments, missing laboratory staff, ruined testing grounds, and mysterious research programs.
Atmosphere, exploration, and mystery are the main features of the game, as the developer has created an atmosphere for gamers to enjoy, explore the entire complex, and create their own story based on what they have discovered.
Features:
* First-person atmospheric horror game.
* Sizeable laboratory and research buildings to explore.
* Progression based on completing tasks and exploring.
* Collectable documents to solve the mystery.
* Interactive systems like doors, keycards and puzzles.
* Atmosphere and sound are designed for horror.
* Discover the secret of the island's experiments.
