Shriekbats are fiercely territorial ceiling dwellers. Its small body is dwarfed by razor-sharp wings. They roost on cave ceilings from tiny posterior legs while hunting small prey, and will aggressively dive-bomb anything they perceive to be too large to consume. Shriekbats have high internal temperature, making them easy to spot with thermal imaging. Body temperature peaks at 121 centigrade.
Shriekbats are the Prime iteration of Skrees. They blend in very well with their surroundings, and drop down from the ceiling where they suicide-bomb their target when threatened. Sometimes you can't avoid them, but once you acquire the Thermal Visor, use it to scope them out way ahead of time. Shooting a single Missile will destroy many at once.
Shriekbats are very similar to Skrees. Their suicide-bomb attack is inspired by when Skrees originally attacked you in the first game - they seemed to explode - when in fact they were burrowing into the ground.
