Ouroboros gate

Ouroboros gate is the entrance to Ouroboros.

Layout
The city itself is surrounded by a wall composed of flatbed trailers lying on their side. Just outside the wall is a trench filled with junk and debris of various shapes and sizes. The city gates are made from a flatbed cut in half and then mounted on the axle of yet another flatbed. A lift-gate from a truck spans the trench at the gate. Rising above the wall on either side of the gate is a small watchtower. Guards are stationed in the watchtowers at all times. Another guard is stationed at the lift-gate.

Daily activity
The guards watch for any large forces approaching the city. If one is spotted then the lift-gate is raised and the gates sealed. The defenders then try to outlast the siege. There are ample food and water stored in the city to last for a month or more. This should be long enough to outlast any attackers who do not have well-established supply lines. Small groups or individuals are allowed to approach and enter the city without any hindrance.

Appearances
Ouroboros did not appear nor was mentioned in any of the published games, but was to appear in Van Buren, the canceled Fallout 3 project by Black Isle Studios. It is not certain if it will appear in any future Fallout game.
