Description
Another image of Level 3999.
Level 3999 is a seemingly infinite arcade—the appearance and layout resembling most arcades present in The Frontrooms (Eating areas, Arcade Areas, etc.) However, the arcade machines contain games that require high-performance PCs or Nintendo devices to play, including Call Of Duty, Minecraft, Miitopia, Terraria, Mario Kart 8, Fortnite, Roblox, and World of Warcraft, among others. Like a typical arcade, the outside area represents a parking lot—cars, streetlights, and trees can be seen through the windows; however, the windows’ strength makes it impossible to enter that area.
The arcade machines are durable and enact relaxing effects on wanderers who play on them. To play a game, simply insert a coin—surprisingly, the machines can take any currency. As wanderers become invested in the game, any sanity loss is mitigated and the wanderer should feel normal within a few minutes. However, attempting to damage the machine, whether in a fit of rage or out of curiosity, will instantly cause the wanderer to faint on the spot. There is luckily no lasting brain damage; regardless, it is not recommended hitting, punching, or swinging at the machines.
The arcade machines may lose their anomalous properties if brought out of the level, but will still work the same. Any game that the wanderer currently using the arcade machine had, or played on older devices, will automatically be incorporated with all the save files avaiable aswell. Level 3999 is one of the most famous levels due to the familiar feeling of security, safety, and comfort. At the same time, the scarcity of other humans in this level may provoke feelings of anxiety and loneliness.
Occasionally, meteorites may rain down from the ceiling, with no known pattern. However, they do not appear to damage the level or any wanderers, so researchers have hypothesized that they are simply illusions created by the light structures.

The "Waiters"
