You have found Server 8166, a place that has remained hidden from the public for years. Right now you are in level 1 of the facility.
The base has more levels that are hidden from plain sight, some are more dangerous than others. There are ways to get to there but... it is secret...
Vault 8166 was rumoured to be a remote server on Roblox where unexplainable things beyond usual are occurring. It is allegedly a secret map run by unknown hackers who can watch or monitor activity between users. It is said that anyone who goes there can gain access to certain information on Roblox and obtain access to an entire database of installations, GUIs, and programs. This facility is believed to be the birthplace of the most dangerous exploits in the games. Software, bots, or viruses are also stored here that have been placed and hidden into Roblox models or plugins. The intentions and history of this place have yet to be known.
On 9/14/2020, the public version of the facility was released. The UI panels within the facility cannot be accessed, and it is implied that some connections to a hidden API network have been disabled, although it is possible to execute some scripts by chatting leaked codes. The facility is divided into multiple "levels," As of date, levels 1, 2, 3, 4, 5, and 7 have been found.
There is also a The Level 5 automated guard, more widely known as the 'Golden Guardian' for its unique golden stripes on the side of its limbs (excluding the head) can be found in Level 5 and it is the most dangerous entity in the Vault due to its unique ability to Perma-ban players from re-entering Vault 8166.
This is different for those who have been banned in the public version. Anyone caught by the Golden Guardian when it was first added will experience this message if they tried to rejoin "Your time is limited." -Mark Twain"
Due to high amounts of incidents occurring in 2022, the golden guardian now only kicks people from the facility.
