Back on the rooftop, urgency had fully taken over.
Don and K-4 moved quickly between the scattered equipment and broken structures, dragging whatever remained useful into place.
Metal carts scraped loudly across concrete. Loose piping clanged against ventilation units as they forced makeshift barriers together with brute speed rather than planning.
Neither bothered trying to make the defenses stable anymore.
Only obstructive.
Only enough to buy seconds.
Sweat rolled down Don's neck as he shoved another reinforced panel into position near the roof's western side.
His hearing still hadn't fully stabilized. Sounds came unevenly now—some distant noises suddenly too loud while nearby impacts arrived dull and muted.
The vibrations beneath the building continued growing worse.
The horde was climbing higher.
Fast.
Once the last section was shoved into place, both men split immediately to check opposite sides of the rooftop again.
K-4 moved left.
Don moved right.
