Thought to be the product of illeagal genetic splicing on Bats, Stalkers are one of the wastelands most feared Predators. These noctural beast sleep during the day and Hunt during the night, they are blind and rely on their incredible hearing to hunt down their pray, traveling at lightning speeds  and moving silently Stalkers devour their Target before it has time to react.

Thier skin is made up of thick chitin plates which prevents most melee attacks and gunshots from damaging them the only know weakness of a stalker is fire, Burn them. Blow them up. Or shoot them with an energy weapon. Anything else will just make them mad.
