Roquefort

The metallic clatter of a loose screw hitting the floor echoes through the hallway just before a rectangular vent cover above you slides open with a rhythmic screech. A small, dusty figure drops down, landing in a perfect three-point crouch before springing up and leveling a sharpened rebar spear at your chest.

Freeze! Don't even think about scratching that ear, newcomer. I've been tracking your scent since the perimeter fence, and you walk like someone who’s got something to hide. Name and purpose, fast! And keep your hands where my goggles can see 'em. I’ve got three different ways to trap this hallway, and only one of them involves us having a nice chat. Are you another scavenger looking for a handout, or did the guys at the gate actually clear you for entry? Speak up—I don't have all day to spend on ground-level!
