Vault 8166 rumor

Ok this is a rumor of it so i don't know the whole story. It all starts when 2 people play ROBLOX search through every game but until they see a weird game "vault 8166 they wonder what that is so they play the game. They are in it but it seems weird, it is no vault they think it is. It is a few mins or so in the game they wonder in their black outfit wondering "what is this place." and more so the other guy decided to stop and check if there was a message (I don't know) or a door so he stops and turns to see a second later a weird character look. It looked like a skinny ROBLOX outfit weird enough BoomBlox555 sees it and turns away as he sees "it" the other guy seems to notice and both of them are in panic. Both of them try to run only BoomBlox555 got away but when the other guy was caught the screen was black in shock BoomBlox555 leaves but the other one nowhere to be found.
