SCP-1016 is appears to be a standard housekey, marked by bloodstains on the fob. When inserted into an unlocked mechanism, nothing will happen. However, when the key is turned in a locked mechanism, it will take its secondary effects. THIS GAME IS 100% POSSIBLE, AND WILL REQUIRE SOME BASIC PROBLEM SOLVING! If at any point something doesn't interact, interact with something else first, then try again (that's the way the game is built). "1016" is a short horror experience, and it should last you aroound 5-10 minutes. This game does not save.
