The description of NOT SCP: Siren Head
The main character had an accident with his wife, seeing a terrible creature that made terrible siren sounds! You need to get out of the forest, how you do it, you decide only.
The main obstacle to flight, the Siren Head (also known as SCP-6789 from the Secret Fund), you need to avoid meeting this creature, as this will not end with anything good.
At the moment, the game has 8 variations of escape and basic mechanics of horror games with the monster.
Good Luck !
