Gun Turret

Nothing known: avoid it by crouching

Automated guns. Crouch (right stick) to pass under their line of fire. Back off and let them shred the Molded chasing you. The one in Research Facility Corridor 1 only switches on after you restore power in the Power Room; the one in the Back Corridor is out of ammo by the time you get there.

The laser tripwires and black pressure plates in the Mine Cart Yard are only visible with the Night Vision Device.
