"Watch the step, it's slicker than crude oil," Ethan hissed, his massive shoulder brushing the damp, curved concrete wall of the lower drainage canal.James didn't answer, his boots splashing silently through the ankle-deep, freezing runoff as he swept the narrow beam of his tactical flashlight across the rusted iron bulkhead ahead. Behind them, Kael’s breathing sounded far too loud in the confined space, a ragged, whistling gasp that betrayed every ounce of his rising panic."I’m watching it," Kael muttered, his voice cracking slightly as he hoisted his diagnostic harness higher onto his chest. "My footing is fine. Just focus on whatever is pinging Noah’s sub-grid.""That ping isn't a glitch, and it isn't an automated sweep," James whispered, pausing just short of the heavy, half-submerged steel door that marked the entrance to the pre-war electrical substation. "It’s looking for the physical broadcast

 "The water-pumping station," Miller said, his voice dropping an octave as he stared at the decrypted schedule scrolling across the workbench monitor. "Those bastards aren't just trying to crack our network. They're going to blow the main intake valves."Ethan slammed his fist down against the edge of the iron table, rattling the scattered tools. "How much time do we have before the detonators sync?""Twenty minutes," Noah barked, his fingers flying across the auxiliary keyboard in a frantic blur. "The trigger signal is locked to a localized timer inside the sub-level filtration plant. If they blow those supports, the lower Silt district will be under six feet of raw industrial runoff before the hour is out.""Move," James ordered, already pivoting toward the back exit with his tactical rifle unslung. "Miller, grab the heavy cutting torch. Ethan, with me. We don't have time to wait for the militia."The cavernous inte

 "If this load-balancing switch slips even a fraction of a millimeter while the perimeter sensors are pinging, every single capacitor in this rack is going to blow right in our faces," Noah warned, his fingers flying across the auxiliary console with frantic precision as a shower of blue sparks spat from the jury-rigged municipal relay."Then don't let it slip," Kael snapped, his hands jammed deep inside the smoking chassis of an old pre-war radar unit as he wrenched a blown copper fuse free with a pair of insulated pliers. "I didn't spend three years at the corporate academy learning advanced telemetry architecture just to watch our entire early-warning grid turn into a pile of expensive scrap metal because your packet rates are too high."Noah glared across the workbench, his bloodshot eyes wide with manic energy. "Your corporate academy didn't teach you how to jury-rig a decentralized Silt circuit using scavenged refrigerator parts and

 The frost on the parapet shattered under James’s heavy palm as he shoved himself upright, his tactical harness clinking with a sharp, metallic rhythm. "Quiet means they’re done adjusting their coordinates. Noah, status on the perimeter arrays.""They're not just pinging us anymore," Noah’s voice rasped through the comms, breathless and spiked with a frantic, digitized distortion. "The whole northern frequency band just lit up like a furnace. Aegis Prime isn't sending a scout squad this time, James. They're moving heavy armor down the District Three freight line.""Heavy armor?" Mia unclipped her kinetic rifle from her sling, her eyes narrowing as she scanned the smog-choked expanse below. "They couldn't get a heavy transport through the narrow maintenance arches without tearing half their treads off.""They aren't using the maintenance arches," Kael’s voice cut in, sharp and breathless as he sprinted up

 "Get into position!" James roared over the deafening screech of grinding steel. "The alley's too tight for their treads—keep them bottled up right there!"The modified industrial ore-hauler—a hulking mass of rust-red scrap plating and reinforced hydraulics—screeched to a halt as its wide front chassis slammed hard against the towering concrete walls of the narrow freight alley. Chunks of masonry rained down from overhead cornices like gray hail, kicking up a blinding cloud of concrete dust and pulverized mortar."They're wedged!" Ethan bellowed, planting his massive boots in the center of the trash-choked gap. "The chassis is too wide! They can't turn the turret and they can't push through!""Don't give them room to back out!" Mia shouted, sliding on her knees through a puddle of leaking chemical coolant. She whipped out an improvised smoke grenade, pulled the pin with her teeth, and hurled it straight into th
