Leech (Aliens: Extermination)

Though not given a specific name in-game, the leech appeared in Aliens: Extermination and appeared to be a part of the Xenomorph life cycle.Like the game's facehuggers, they would leap at the screen and take damage slowly.Before doing so, they would hang from walls and ceiling until the player got near enough to perform the jump.They would be a product of scientific experimentation, though, as the whole complex is run by xenomorph-studying androids.
