The universe of the movie A quiet place. If u don’t know what A quiet place is, it’s basically an alien apocalypse, the aliens came here because their home planet was destroyed, the aliens only hear and can hear very well over a large distance, the only way to kill them is by using their amazing hearing to your advantage since they have armored skin, if u do use their hearing to your advantage then the alien will freak out and their armor would peal off from their head until the sound stops, thus allowing u to hit their head and it actually damage them, the aliens kill animals and humans and are very fast,the aliens hate water, The only occasion when someone can talk at whatever volume they like is during a loud thunderstorm or under a waterfall oh, and their actually called death angels
