SCP Nickname: A Hole in the Wall
Ingame mechanics: It could give you a level 1 or level 2 key card so theres two ways to get one. I think it is always the same: Get the level 1 key card (most lets players miss the card and there isn't another way to get one, so they cant continue) Then go into the glass room to get a level 2 and then to 914 to get at least a level 3 card.
"SCP-1162 is open for testing by any person with Level 1 or greater clearance level."
If the door is not opened (maybe you dont found the card) for some time the hole could be randomly in the facility. Then the hole in the containment cell would be just a hole. "The previous hole remains, but shows no abnormal properties."
Before you put your hand in the hole there could be a screen asking if you want to put your hand in the hole, just to get a nice effect.
Spoiler
Then you lose a item in your inventory and get another.It could give you some other items before a key card.
Like the electronic components that you can get if you put the s-nav on course.
It must not be something the subject searched in his life so this is ok. "Notes: This is the first test that has produced something the subject hasn't lost."
Or other more useless stuff like this
Spoiler
To prevent overuse it could just give you a pen for a pen. "Sr. Researcher Grant proceeded to test an additional 30 times, each time losing and gaining one standard ballpoint pen." And if you dont have anything it could took of your clothes. Maybe you must get some new ones. But if you dont you can die by the hole. "Note: Subject was naked and holding no items at the time." "Item Lost: Subject complained of intense abdominal pain upon removing his hand from SCP-1162, then collapsed. It was discovered that his left kidney was missing, and all vessels leading to the kidney cleanly severed."
Death message in the chamber: "Subject D-9341 was found naked and dead in the containment chamber of SCP-1162. It was discovered that his left kidney was missing, and all vessels leading to the kidney cleanly severed."
Death message: Subject D-9341 was found at [Data Expunged] near a hole that was later found to be a hole produced by SCP-1162. It was discovered that his left kidney was missing, and all vessels leading to the kidney cleanly severed."
So what do you think of it?
