The UFO (Unidentified Flying Object), otherwise known as the USO (Unidentified Submerged Object), is a large Easter egg found in Stranded Deep. It is a large circular object often associated with invading aliens, and can be found at the very bottom of the sea, often alongside sea mines. The presence of the UFO/USO suggests that other lifeforms of other worlds had at one point visited these parts prior to the events of the game. Due to the amount of time spent submerged in the ocean, the UFO/USO shows heavy signs of decomposition, with algae growing all over its form. It currently has no function in the game other than to serve as an aesthetic feature.
