Death Angel

The Death Angels are a hostile race of aliens who arrived on Earth via a meteorite and have since began killing off nearly all life on Earth.

Biology
The Death Angels are emaciated, vaguely humanoid creatures whose entire bodies are covered by many plates of chitinous armor. They appear to have arms with prehensile digits but are only ever observed using their limbs for locomotion.

Death Angels hunt by sound, and are completely blind. They have sensitive plates lining the front of their faces that can extend and contract to help them gauge direction of where sound is coming from. The back of their heads are capable of unfolding into massive eardrum-like organ, further enhancing their hearing to detect even subtle changes in sound, but doing so also leaves the underside of the armor exposed, rendering them vulnerable.

Intelligence
It is debated if they are sapient, as their only objective seems to be to hunt for prey, and they are never observed communicating with each other. However, these animals are very smart when it comes to the hunting, as they have been seen inside buildings they can't get into without opening a type of door, and they have the mental ability to attach themselves to an object (such as a boat) to get to a certain location. Rarely are they seen actually eating humans. They have also been seen to be able to easily rip through metal, steel, and other hard materials to get to their target.

Weaknesses
Because of their super hearing abilities, high frequencies will disorient them and can be used to immobilize them or even drive them away. Extremely high frequencies can even cause them physical pain and distress, and even render them temporarily unconscious. It also renders them vulnerable, as they are seen opening their armored plates to expose their flesh. [weak spot]

While the outside of their body is heavily armored, their insides are soft and fleshy, and timing a shotgun blast with a Death Angel opening its sensory organs or mouth can instantly kill it. However, doing so risks attracting the attention of even more Death Angels. The best method for survival is to remain as silent as possible.

As they are completely blind, evading them is as simple as being as quiet as possible, or trigger a noise louder than yourself to distract it. Another weakness of Death Angels is their inability to distinguish artificial or Human sounds from natural sounds. Taking this weakness as an advantage, Evelyn managed to escape from a Death Angel by triggering a fire faucet and enter to the secured hideout.

Additionally, due to the weight of their armor, they will sink if they become submerged in water of sufficient depth; they are capable of navigating shallow water easily. With this in mind, many survivors have been able to continue some semblance of normalcy by establishing settlements on islands.

History
Death Angels arrived on Earth on a meteorite that crashed in Mexico. The meteorite on which they held onto was a chunk of their destroyed home planet.

Invasion of 2020
In the year 2020, a meteor landed in Mexico which contained dormant Death Angels. In the first hours of the invasion, military forces from around the globe began to fight back, but the creatures' armored shells proved too strong for bullets, bombs, and even bio-weapons. Over the span of the next 3 months, the Death Angels had become widespread and had wiped out a considerable portion of the Earth's population. A year later, the last remnants of humanity survive in small groups by making as little noise as possible.
