I played them all but nowadays I only replay the marine campaigns every now and then.

Facehuggers in AVP1 are perfect. Makes me break out into a cold sweat everytime while being an incredibly fair enemy.

Facehuggers in AVP2 are just retarded. Insanely fast, dodging every grenade launcher round you shoot at them, glitchily leaping at your face and not grabbing on since it's not registering properly, it's an odd mess. Thankfully they're not really wandering in the wild most of the time.
