This one is SCP-Containment Breach, as the description says. The games only in alpha though, so it's pretty buggy and there's a lot that's being added. I suggest you try SCP-087-B first, it's much scarier than this is at the moment. There is an SCP-087, but it's not as good if you ask me.
I will now find out if I can post links.

ok i got down to the 11th floor, and im scared shitless already, wat do

oh my god....

Here's a hint, buddy. If you don't mind putting on a bit of weight, it's a great help to have some sweet food sitting near you that you can bite down on and distract yourself with when you get spooked.

I have pizza :D

Mmm, pizza. Not too hot, I hope, it'd be problematic if you had a slice in your mouth when the monster decides to scare the bejeezus out of you and you burned yourself.

Ahh yes, but on its perfect temperature, also im currently not playing, but ill take a trip to the store and by some jizzable candy.

I had over a kilogram of strawberry flavoured sour strings, it was deliciously terrifying.

Quite! I remember the days I was in sweden, everything was so cheap, kilos and kilos of candy, and boxes and boxes of snus (small teabags likethings with nicotine you can put under your lip, instead of smoking).
Oh the happiness.

Well, I actually own a membership card for the store where other shops get their stock. You ever had over ten litres of icecream in your back freezer for less than half the price it usually would? That shit rules.

I spilled my masturbating juice.

I find the lack of green thumbs... disturbing. *Rectifies*

Thanks, bro, you're awesome.
