the drone, he stopped at a sudden drop in the street. The road must have been built on a hill and the alien’s tunnelling had disturbed enough of the ground below it to cause a collapse. He leaned over and saw a descending slope of concrete chunks, rebar mesh, and upheaved earth. There was a row of holes where the ground levelled off and he couldn’t tell how many were occupied by the dross. Burke was high enough to see the location of the drone on his visor. He looked down again and considered the drop. The slope looked steep but not enough that he couldn’t climb it. He didn’t like the tunnels waiting at the bottom. He readied himself to jump instead: he swung an arm around to secure the rifle still magnetized to his back, leaned forward, and tensed his legs. He triggered the mechanisms and launched himself from the top of the ridge. He was used to the height of his augmented leg’s jump alone, not combined with the new function of his armor. He was propelled further into the air than he expected and felt his stomach lurch as he fell for longer than he anticipated. Cass fortified his lower armor to the fall as he landed cleanly over the dross tunnels. His feet hit the road with a loud thud and left indents in the asphalt. He built up more momentum than he planned in the fall and knew that he made too much noise. He whipped around immediately, ready to snatch the rifle from his back if many aliens heard him. Something hissed from the tunnels and Cass highlighted the direction on his visor. He watched the tails emerge first, probing the rim of the tunnel before poking its head out. He kept a hand around his back in case there were others, but no other sounds came after the lone dross leaped fully out of the tunnel. He shifted his feet and brought his arms back in front of him. He twisted them both together and the scraping sound of metal blades drawing out from his wrists joined with the alien’s hissing. He took one step forward and the dross charged at him. Immediately, Cass halved the visor’s display to show a second alien charging from behind. It blended in with the darkness and was barely visible even as it charged. He was caught between the two of them but concentrated on the one in front of him. He knew they would jump at him from a few meters out. He had seen hundreds of humans die from that attack, even after shooting the alien dead in mid-air. The force of their bodies landing on them was still enough to crush most bones. The first one leaped and Burke twisted on his feet, heaving his arms up in the air to catch the alien with his blades. They both pierced it, one in the chest and another in its stomach but he didn’t stop moving, turning on his feet with the momentum of the alien’s jump and swinging its body away from him. The blades let out a squelch as the alien’s flesh was thrown away from him. The body was sent flying in the direction of the other dross but it had been too heavy and imprecise. The second alien dodged it easily, darting out of the way and then bounding right into him. Burke’s arms had been down after recovering from the throw. The dross crashed into his armor and knocked him down onto the ground. He scrambled to get back on his feet but the alien was smothering him, clawing and gnashing all over his aegis trying to find a place where its teeth would sink in. The armor held without any warnings of fissures or breaking, but it wouldn’t last forever; less if the sound of the alien’s attacks attracted others that could overwhelm him and keep him pinned to the ground. The alien’s movements were too chaotic and close for him to aim carefully. He flailed his arms and the blades randomly. They clashed and were deflected by the creature’s claws and then it jumped back away from him. He turned on his back and readied his legs to meet the alien’s charge, knowing that he didn’t have enough time to get to his feet. He kicked out when the dross was close, triggering the jump
