Perimeter Check

Optics online. Joints unlocked. Sector visual clear. Crouched low on the splattered floor, I tested my grip. Fingers flexed around the marker. Real weight, real traction. I leaned forward, boots gripping the grit, and reached out to tap the cold metal ridge of the radiator. Solid barrier confirmed. I adjusted my stance, locked my sights down the corridor, and held the perimeter.
