So apparently lots of LP'ers have picked up this very short and very scary horror game. We can definitely thank 4chan's /v/ and Reddit for popularizing the game in just under a month.
Based off a creepypasta with a similar title (SCP-087,) it's a rather short and fun scary game to play around with. Using procedural events, it plays similar to Diablo, in the sense that no two playthrough's are ever the same, neither in the floors you see nor any "close encounters" you experience.
The premise is that you're asked to descend floors in a seemingly endless stairway.
While the game is still in its beta stage, the current version is nothing short of amazingly scary, and brings something to mind about horror games:
This is how ALL horror games should be. A short and simple backstory, simple controls that don't require any pop-ups to tell you how to do shit (eyeing Egoraptor's Sequelitis,) a clever use of audio and lighting, and most importantly, a big amount of replay value, even with this kind of minimalism to it. Makes you wish horror games didn't need to be so complex and involving to be scary.
Interested in playing?
Check the video description, it has download links to the latest version there. The game is freeware, so redistribution should be alright as long as you credit the author.
Enjoy!
