Welcome to the SCP Foundation. This game is based on a well known SCP. SCP - 173 (The Sculpture) ~ Description: a humanoid statue made of concrete, rebar, and spray paint that is immobile when directly observed. However, it can attack and break the necks of people when their line of sight is broken, and it can move extremely fast, even multiple meters while an observer blinks. Some say it's incredibly intelligent, while others might think it's more like a walking slab of concrete with stunted limbs. SCP-173 was contained in 1993 and moved to Site-19, but its origin is still unknown.
