Leech (Aliens: Extermination)

Though not given a specific name, the Leech appeared in Aliens: Extermination, presumed to be a part of the Xenomorph life cycle. Like the game's Facehuggers, they hung from the walls and ceiling until the player was near enough, and then leapt at the screen and took damage slowly.

They were likely a product of scientific experimentation, as the whole complex was run by Xenomorph-studying androids.
