In Back O' Beyond, there is a myth in which if the player drives through a wall, they will fall and get teleported to a random place. As the player enters the mountain wall in a vehicle, they will drive straight through the wall and drop down into what looks like, a blue background (most likely Blue Hell.) However, if the player doesn't gain enough speed, the player's vehicle may get stuck on the wall. The player may then spawn in a random location, losing their vehicle or spawn in a random location together with the vehicle. Sometimes the player may find them-self infinitely falling through Blue Hell in a vehicle. To end this, just exit your vehicle and you'll spawn in a random location. It is unknown why this happens, but evidence suggests that the wall is only a texture not a solid, so the player can drive and then fall through it. It can be difficult to make this glitch work, but the results are astonishing.
However, a game developer has said this: "The point is if you get 100 meters beneath level. (Z = -100.0 in technical terms, it's at Z = 0.0, inside a 3D space with XYZ.) the player will be teleported to the closest land, to prevent the player from falling forever. This happens everywhere, but normally, the player could not go that deep without any glitches, bugs or modifications to the game itself. This is a type of variant of the blue hell glitch that just teleports player to the closest relevant location on the XYZ axis. It is proven to exist.
