Back on the rooftop, the fighting never slowed.
If anything, the horde climbed harder.
More hands appeared over the rooftop edges every few seconds now, fingers splitting apart against rough concrete while ruined faces dragged themselves upward through blood and shattered glass.
Seven at a time. Nine at a time. Sometimes more.
Bodies piled over each other so aggressively that several got crushed against the ledge before even reaching the top, ribs snapping inward beneath the weight of those still climbing behind them.
Don and K-4 kept meeting them head-on anyway.
K-4 drove his elbow into the face of a bald woman whose jaw had split open all the way to her ears, then immediately pivoted and slammed the butt of his combat knife through another man's eye socket before the corpse had fully climbed over the edge.
Blood sprayed across his face and exposed neck while his wounded hand shook harder from the strain.
