Alien: Isolation’s apex predator, that two-mouthed berserker freak, isn’t the smartest xenomorph around. Stuck behind an overturned hospital bed while H.R. Giger’s monster paces hungrily around in front of you? Just toss a flare into the opposite corner of the room. The dummy will go crouch over it like a stoned freshman in front of a Lite Brite. The thing is startling when it wrenches open a locker to eat you or when it oozes saliva down from a vent above you, but that’s just because of the raw, animalistic threat it poses. It’s nerve wracking, but not necessarily scary.
Fear—real, knuckle-sweat fear—comes not from the alien’s face but the noise it makes.
