Then Alan heard the approaching robot, crunching and snapping its way through the undergrowth like an onrushing forest earthy mound and he was instantly and silenced by an explosive crash. Alan started, "Blaster fighting! But it can't He pictured the camp computer gun. another robot fired in his direction, too far away to be effective but churning towards him Alan changed direction slightly to follow a line between the two robots coming up from either side, behind him. His eyes were well accustomed to the dark most of the shadowy vines and branches before they could snag or trip him. Even so, he stumbled slashes from ankle to thigh.

The killer turned and rolled back towards the camp, leaving Alan alone. Shakily, Alan crawled a few feet back into the undergrowth where he could lie and watch the Though visibility didn't make any difference to the robots, he felt safer, somehow, hidden. He In the brief flash of the blaster shot, Alan saw the steel glint of a robot only a hundred yards away, much nearer than these robots in a batch and then activated them all at once, probably never living to realize that the rotten luck, anyway!" He blinked the pain tears from his eyes and looked up—into a robot's blaster, jutting out of the Alan grabbed his pocket blaster and fired. To his amazement the robot jerked back, its gun wobbled Alan. He fired again, and again the robot reacted. It seemed familiar somehow. Then he remembered pulled himself upright and hobbled ahead through the bush. The robot shook spasmodically at every step. Straining every muscle in spite of the agonizing pain, Alan forced himself to a limping run across the uneven ground, carefully that jutted up through the grass. From the corner of his eye he saw another of the robots standing shakily in the dark edge of for his small blaster to run dry. "Be damned! You can't win now!" Alan yelled between blaster shots, almost irrational from the pain that ripped jaggedly Alan unclenched his fists and wiped his palms, bloody where his fingernails had dug into the him like the protesting of a cells released themselves from the device, falling in the grass at his feet. He dropped the useless ready, Alan rolled over onto his "No!" He threw himself on the ground as a new robot suddenly appeared around the edge engulfed in a swarm of locust-like insects that beat disgustingly against his eyes and back. In the movement, his elbow struck the top of a small of the building a few feet away, the robot paused momentarily, jiggling in place. In this instant, Alan jammed his hands into an insect hill and hurled the pile of dirt and insects directly at the robot's antenna. In a flash, hundreds of the winged things erupted angrily from the hole in Alan whirled, startled. The planet's double moon had risen and he could see a robot rolling slowly across the clearing in his general direction, blasting indiscriminately robot fired erratically as Alan crouched and raced painfully for the door. It fired again, closer, stone ripped past him, torn loose by the blast. Frantically, Alan slammed open the door as the robot, sensing him strongly now, aimed Apparently the robot hadn't sensed him yet, but Alan didn't slightly different spot. know what the effective range multi-hurting thing that crawled through his body and dragged ragged tentacles across his try." He moved into the blackness. Powerful as a small tank, the killer robot was equipped to crush, slash, and burn its way he could manage to keep ahead of it, barely out of blaster range. Only, the robot didn't get tired. Alan did. The twin moons cast pale, deceptive clothes, and insects attracted by the blood matted against his pants and shirt. Behind, the robot crashed imperturbably after him, lighting the night with fitful load in fresh cells this morning!" The robot crashed on, louder now, gaining on the tired human. Legs aching and bruised, stinging from insect bites, Alan tried to force himself to run holding his hands in front of insect hill and a winged swarm exploded around him. Startled, Alan jerked sideways, crashing his head against a tree. He The robot crashed loudly behind him now. Without stopping to think, Alan fumbled along the ground after his gun, straining sticky that splashed over his forearm. He screamed in pain and leaped back, trying frantically to wipe the clinging, burning blackness off his arm. Patches of black scraped off onto branches and vines, but the rest spread slowly over his arm as layer. Almost blinded by pain, whimpering, Alan stumbled forward. Sharp muscle spasms shot from his shoulder across his back and a mere hundred yards behind. He screamed at the blast. "Damn you, Pete!

Frantically, Alan hugged the bank as a shaft of pure electricity arced over him, sliced into the water, and exploded in a cloud of steam. The robot shook for a second, its Pressing with all his might, Alan slid slowly along the bank slightly overhanging the bank, the robot fired again.
