If you're not familiar with the SCP Foundation Wiki, I'll give you a short background; it's a fairground for amateur horror writers to write a wiki on an anomalous or extraordinary find from a foundation called the SCP Foundation (Serve, Contain, Protect/Special Containment Procedures), who were inducted to find and contain dangerous or safe anomalies to keep the public safe or in check. These can range from a young woman who sees pictures like security footage, ice that freezes above zero degrees Celsius and melts below it, and an alien reptile capable of adapting to any situation or harm, rendering it indestructible. These SCPs, the name given to them is the action taken against them, are kept in secure containment in remote areas around the globe (with some exceptions, like the Tibetan Rope To Heaven or the Fountain of Youth).
This game is about what happens during a containment breach of some of the deadliest SCPs kept on Foundation premises, specifically Site-19, the focus of the game being SCP-173.
SCP-173 is "...constructed from concrete and rebar with traces of Krylon brand spray paint. SCP-173 is animate and extremely hostile. The object cannot move while within a direct line of sight. Line of sight must not be broken at any time with SCP-173. Personnel assigned to enter container are instructed to alert one another before blinking. Object is reported to attack by snapping the neck at the base of the skull, or by strangulation. In the event of an attack, personnel are to observe Class 4 hazardous object containment procedures."
In short, don't blink when around this guy. Which is too bad, seeing as a human being under high-stress situations feels the urge to blink once every few seconds. That may or may not be time enough to get to an area safe from utterly destroyed by The Statue. You actually start out in SCP-173's pen, where you and two other D-Class employees (D-Class translates to "death row lab rat") were assigned to clean his pen. The door malfunctions, the power goes out, and you're stuck in near blackness with a monster that can move extreme speeds when not in direct eye contact. Fucking nighmarish. I've almost pissed myself more times than I can count playing this game.
It's a survival horror game centered around not getting destroyed by SCP-173. You move around randomly generated dark hallways, so each playthrough is different, and due to limited content as of alpha build v0.1.2, the playthroughs differentiating from each other adds a lot to the immersion and feeling of helplessness, you never truly know whether this guy might be lurking around the corner. Seriously, as a guy who's attempted to play through Justine multiple times, I can say that this is top notch survival horror.
However, SCP-173 isn't the only tough guy to escape it's SCP containment. SCP-106, "The Old Man," has also breached its containment, probably due to the power knocking out the floodlights of its enclosure. This guy melts into a pocket dimension when touching a wall or other flat surface, and can appear anywhere the wall or surface extends, be it the opposite side of the wall, the ceiling, or the floor. The only way to get tipped off that Old Man's coming a -knockin' is the corrosion damage he does to the area he phases through. Which is REALLY hard to see in the dark.
Another game made by this developer as an apparent weekend break was SCP-87b, a game revolving around SCP-87, a staircase that descends indefinitely, bringing a lot of psychological scarring along with it. You can descend as far as you want in the game, too, so long as you aren't killed off by a random event that could occur while walking. D-9884 got down two kilometers before she lost her shit, how far will you go?
As I've said, both games have ruffled my feathers on multiple occasions, but I could just be a jumpy dude. You be the judge.
