Pump Six and Other Stories by Paolo Bacigalupi

sky. The shards fluttered down around us, black metallic petals absorbing our enemy's radar and heat detection while we rolled to jarred vulnerable stops in muddy scree.
    The hunter blew over the ridge, Hentasas shrieking, a blazing target. I dragged myself upright and ran for the ridge, my feet churning through yellow tailings mud and rags of jaundiced snow. Behind me, Jaak was down with smashed arms. The leaves of his exoskeleton marked his roll path, a long trail of black shimmering metal. Lisa lay a hundred yards away, her femur rammed through her thigh like a bright white exclamation mark.
    I reached the top of the ridge and stared down into the valley.
    Nothing.
    I dialed up the magnification of my helmet. The monotonous slopes of more tailings rubble spread out below me. Boulders, some as large as our HEV, some cracked and shattered by high explosives, shared the slopes with the unstable yellow shale and fine grit of waste materials from SesCo's operations.
    Jaak slipped up beside me, followed a moment later by Lisa, her flight suit's leg torn and bloodied. She wiped yellow mud off her face and ate it as she studied the valley below. "Anything?"
    I shook my head. "Nothing yet. You okay?"
    "Clean break."
    Jaak pointed. "There!"
    Down in the valley, something was running, flushed by the hunter. It slipped along a shallow creek, viscous with tailings acid. The ship herded it toward us. Nothing. No missile fire. No slag. Just the running creature. A mass of tangled hair. Quadrupedal. Splattered with mud.
    "Some kind of bio-job?" I wondered.
    "It doesn't have any hands," Lisa murmured.
    "No equipment either."
    Jaak muttered. "What kind of sick bastard makes a bio-job without hands?"
    I searched the nearby ridgelines. "Decoy, maybe?"
    Jaak checked his scanner data, piped in from the hunter's more aggressive instruments. "I don't think so. Can we put the hunter up higher? I want to look around."
    At Lisa's command, the hunter rose, allowing its sensors a fuller reach. The howl of its turbofans became muted as it gained altitude.
    Jaak waited as more data spat into his heads-up display. "Nope, nothing. And no new alerts from any of the perimeter stations, either. We're alone."
    Lisa shook her head. "We should have just dropped a mini on it from base."
    Down in the valley, the bio-job's headlong run slowed to a trot. It seemed unaware of us. Closer now, we could make out its shape: A shaggy quadruped with a tail. Dreadlocked hair dangled from its shanks like ornaments, tagged with tailings mud clods. It was stained around its legs from the acids of the catchment ponds, as though it had forded streams of urine.
    "That's one ugly bio-job," I said.
    Lisa shouldered her 101. "Bio-melt when I'm done with it."
    "Wait!" Jaak said. "Don't slag it!"
    Lisa glanced over at him, irritated. "What now?"
    "That's not a bio-job at all," Jaak whispered. "That's a dog."
    He stood suddenly and jumped over the hillside, running headlong down the scree toward the animal.
    "Wait!" Lisa called, but Jaak was already fully exposed and blurring to his top speed.
    The animal took one look at Jaak, whooping and hollering as he came roaring down the slope, then turned and ran. It was no match for Jaak. Half a minute later he overtook the animal.
    Lisa and I exchanged glances. "Well," she said, "it's awfully slow if it's a bio-job. I've seen centaurs walk faster."
    By the time we caught up with Jaak and the animal, Jaak had it cornered in a dull gully. The animal stood in the center of a trickling ditch of sludgy water, shaking and growling and baring its teeth at us as we surrounded it. It tried to break around us, but Jaak kept it corralled easily.
    Up close, the animal seemed even more pathetic than from a distance, a good thirty kilos of snarling mange. Its paws were slashed and bloody and patches of fur were torn away, revealing festering chemical burns underneath.
    "I'll be damned," I breathed, staring at the animal. "It really looks like a dog."
    Jaak
