The Beached-Things

"They're here...don't even breathe. Or move!"

- Sam to his assistant after sensing Gazers

The Beached-Things or BTs are the overarching antagonists of the 2019 open-world sci-fi action video game of Hideo Kojima, Death Stranding.

They are extremely powerful and nearly invisible extraterrestrial beings which have somehow "stranded" themselves on Earth following the titular cataclysmic event of Death Stranding. In addition, they are beings to be mostly known as antagonistic towards the living and towards any kind of being that come across them. They are mainly seeking to devour the entire human race, and, later to recolonize the Earth as their own planet.

When they are eating humans, they are causing to massive explosions known as the Voidouts, which is leaving large craters behind in the site of a human they have killed, which became their own greatest signature pattern of behaviour, but even though that Sam ,the game's main character, is able to return from a Voidout, he is leaving a larger crater from the point of his death.

Death Stranding
The extraterrestrial entities known as the Beached-Things are coming from an unknown origin source, yet they have arrived to Earth years prior to the game's main storyline, following the titular destructive event of the Death Stranding, as they have stranded themselves in Earth somehow.

They are nearly unavailable to defeat so as the game's story has concluded, it is unknown if the BTs have extincted nor disappeared to their respective planet.

Types
There are 3 different types of Beached-Things as following;

Gazers
Gazers are floating BTs which are manifesting themselves with the onset of the Timefall. They are having the ability to sense by sound, and thus, are unable to sense Sam while he is immobile and holding his breath.

If Sam moves, gazers will disappear and only become visible again once he stops moving. They cannot be killed, but can be temporarily immobilized with a bola gun infused with Sam's blood; while immobilized by a bola, gazers will remain visible to Sam even while he is moving.

Hunters
Hunters are these kinds of Beached-Things which are mostly sent after Sam once he had already alerted the Gazers. They appear as tar handprints when seeking out prey on their own.

Should they be sent to grab Sam by alerted gazers, they will manifest from and attempt to drag him down into the surrounding tar, the success of which is partly determined by the amount of cargo Sam is carrying at a given time. Should they succeed, they will drag Sam away to a catcher-type BT.

Catchers
These are the most large and gigantic types of BTs ,appearing only when Sam is dragged away by hunters. They are made of antimatter, and if Sam is eaten by one of them, a voidout will be triggered, wiping the nearby area off the map.

If a Catcher is defeated, their body will shatter into many chiral crystals. There are 2 currently known types of the Catchers as following:
 * An unnamed quadruped catcher will pounce around the area of conflict in an attempt to eat Sam. Higgs, the game's main antagonist, has managed to control the ability of manifesting one of those and demonstrated the ability to manifest this type of Catcher. This one appears as a four-legged octopus-like creature. Hideo Kojima, the game's director and creator, is referring to this type of Catcher as 雑魚 (zako, lit. "small fish"), and has noted that it is one of the weakest of Catcher-type BTs.
 * An unnamed multi-limb catcher is fought by Sam after he is dragged away by hunters in the Japanese release date trailer of the game.

Powers and Abilities

Trivia
