Scp173

I do dispair when it comes to labeling this mature or not.
Do tell me if it's enough that I probably should make it a warning.

I think I have a love/hate relationship with this bastard. You'd have to pay me quite a lot to play this game in all seriousness.
I'd surely get a panic attack. (It's a wonder how I play amnesia sometimes)
But for those of you who have no idea about this strange things mythos I'll tell you why I don't like it.
As the story goes in Containment breach, you're an inmate tasked with aiding in cleaning SCP173's cell, when all of you have the misfortune of blinking at once, things turn sour instantly.
For this very reason, the "Keter" class monster is very dangerous, moving only when it's not being watched. At which point it moves unnaturally fast and will quickly dispatch of it's prey. How it does so is uncertain. It could snap their neck or deliver a contusion from a high velocity impact. Either way it will kill you without fail when it's close enough.
In the game you have to find safety while illuding this and a few other SCPs. (Including a duck with similar teleporting characteristics?)
All the while a reoccuring enemy is the presence of THIS THING!
A blinking meter slowly runs out on the side menue, or you can manually blink by pressing a key. If you're far enough away or there is something between you and SCP173 you'll be safe to do so.

In conclusion I find the concept of it VERY TERRIFYING.
