From my very WIP AvP tabletop ruleset, under Behavioral Adaptations:
Intimidation Imperative
This Alien shows an uncanny, if crude understanding of the psychology of its prey. It will go out of its way to take down targets in spectacularly bloody displays of speed and aggression in full view their comrades, or brutalize the carcasses of isolated kills to further sap morale upon their discovery.
Just my thoughts on it really.
