The journal really makes the cut when it comes to SCP-3008.
It could be made into a survival game or maybe it could be implemented inside the game.
Could be an Ikea survival horror multiplayer game.
The description really makes it sound like a good game/feature
Although the name seems innocent the game is gonna be much scarier than that.
You have to scavenge for food and water while building a small hideout with weapons (Multiplayer would be a nice feature if this is in a different game/npcs to replace multiplayer)
While in night you can sleep or try to find a way out (The night time gives you a better chance at finding the exit or better food/items so people would actually go at night time)
While finding the exit you might go to the actual start of where you can from or a close by area which you can go trough and come back to the scp while the door vanishes behind you.
If you are too lazy to read about the monsters and such in the fourm:
Food, water etc are optional of course.
