It's a green, confusing, endless, scary labyrinth where SCP-106 takes his victims to before killing them. unless you're already where he lives, or have managed to escape. Oh, don't worry though, if he catches you, he won't kill you. His walking pace is just slightly slower than your running pace. Looking like the rotting corpse of an elderly man, he can appear at random emerging from a puddle of black slime, and then he'll chase you. Far more blood than a single human could produce. Another possible encounter in the Entrance Zone is arguably even worse: it's just 096 sitting alone in a containment chamber with the doors broken down, and the floors, walls, and ceilings CAKED with blood.The wiki states that someone tried to hide from it by sitting in a diving bell at the bottom of the ocean. The best you can hope for is to get pulled into 106's pocket dimension, the one place he can't reach you.and then he may just be waiting for you when you get back. Once you've seen its face, unless you're an absolute god at the game or EXTREMELY lucky, you're dead. When they say, 'you cannot escape', they MEAN it.Don't worry though, he's harmless even if you bump into him, unless you look at his face. Occasionally he may be found roaming other hallways in the Heavy Containment Zone as well, sobbing all the while. What's worse? You HAVE to go into that room in order to progress with the game, and 096 will still be patrolling.

As stated above, there's nothing left but a pool of blood when you reach that spot. When you first encounter it, we see a guard accidentally viewing its face and firing wildly at it before it kills him offscreen.It's not known what exactly it does when it catches you, as nothing is ever found of the victims but a puddle of blood, but judging by the meaty tearing sounds, it isn't pretty. First, it stands up and goes crazy, flailing wildly in place and making distorted crying noises for several seconds, then it starts chasing you with no way to stop it or outrun it. Be glad you don't have to deal with this. In cases of those trying to perform Loophole Abuse through one means or another to technically never fully blink, it's dropped the rule. A sort of unspoken rule it abides by to give its victims a fair chance. Worse yet, the only reason you have potential of escape and it's 'held back' by the blinking is because, Depending on the Writer, SCP-173 treats the whole thing as little more than a game.If you can't see it, it moves at inhuman speeds, almost silently. yet somehow it can excrete substances that seem like a combination of blood and waste. It's animate, but experimentation has revealed no actual signs of life. It's like the Weeping Angels put through a creepypasta filter. It kind of doesn't help that its face, head and body in general kind of resembles a grinning baby reaching out for something.When you hear scraping noises signaling that 173's nearby.Or when you blink and he suddenly appears in the room with you.You're just walking down the dark hall with the creepy ambiance playing when you turn a corner and find SCP-173 right in front of you, very close to killing you. If you examine the scene closely, you'll see a broken air-duct where 173 escaped meaning that it could be anywhere in the building. 173 then kills two D-Classes and a guard while the lights flicker and when the lights finally die completely, it's gone with you as the only survivor. You are escorted to SCP-173's cell and everything's fine at first, until the doors start malfunctioning and the lights flicker.
