Vault 8166 rumor

What Is Vault 8166?
 Vault 8166  was rumored for years to be a hidden server on  Roblox  where unexplainable things beyond usual are occurring. It is allegedly a secret map ran by unknown hackers which have the ability to watch or monitor activity going on 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 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 was released. The UI panels within the facility cannot be accessed and it is implied that all connections to a hidden API network have been disabled, although is possible to execute some scripts by chatting leaked codes. The facility is divided into multiple "levels", and as of date level 1, 2, 3, 4, 5 and 7 have been found.

The First Mention Of Vault 8166
On November 15th 2016, an anonymous user created a thread on the Roblox talk sub-forum. This user was claiming to have accidentally gotten onto this "unknown place" while testing out a teleporter for a game. The thread was a brief summary on how "evil is operating behind our eyes", and that there is a place where dangerous people are gaining access to user profiles and other information as we speak. This secret place was referred to as "Vault 8166". A few hours after the thread was posted, word went out. Mysteriously, the thread was nowhere to be found, along with the user who posted it. The thread may have been taken off by moderators. If not, something else was at work and it wanted the forum thread gone.

First Leaked Incident
The first footage of the facility(first leaked in January 2017) shows two users with common exploiter avatars walking through one of the main hallways of the facility. Within seconds a "creature" comes out and attacks both users, with the footage ending in the blue screen of death. For years there has been speculation and debate as to what this entity actually is. It is usually spotted near the entrance to level 3, and most believe it to be a "guardian" of the facility. Rising incidents also include the "smoke detectors" seen throughout the base emitting paranormal behavior, including their eye turning red when agitated. They are placed throughout the facility and are usually harmless but sometimes have the ability to crash the victim. These [devices?] are most likely controlled by unknown third parties in order to watch users who enter the base.

Incident 5/20/2021
On 5/20/2021, the automated guardian entity of level 5 went rogue and became controlled by an unknown exploiter. It was able to escape the pit of Level 5 and make its way into level 4 and then into Level 1. How the NPC was able to escape Level 5 and move around the base is unsolved. Footage is available of the incident.

 * .[[File:Level 7 Portal.png]]
 * Level 8 - Unknown
 * Level 9 - Unknown

The hallway shown in the first footage in 2016 takes place in Level 1, and it was most likely that the guardian was chasing the users because they tried to enter Level 3.

Different screen boxes showing storage logs contain a record of scripts, plugins, and other assets which have been submitted to the database of Vault 8166. None of the usernames are shown, but one of the screen logs above the big white room in Level 1 contains an entry "EXTRA LAYER SECURITY THEY KNOW" submitted on 10/30/2016, which was around the time that rumors started to surface about Vault 8166.

A public document has surfaced with insider info on Vault 8166. It contains brief history and information of the facility. An important code is revealed on page 8 which gives any user the ability to bypass some security measures in Vault 8166. The author is anonymous.
