Extinction

had burrowed. I judged the process as too slow, however. We would never be able to drill our way into this mountain’s heart if it took a full minute for every yard of progress.

“Sir, up here!” said Major Yamada, my tank commander. “Lead drill-tank, reporting a sudden change in rock-density!”

“Talk to me, Major.”

“If you get in about thirty feet, it gets a lot easier, sir. A lot easier.”

I slapped Kwon’s chest as I ran by him. He caught on and trotted after me, as we ran toward the front of our long line of drill-tanks and men.

My celebration was short-lived. The Worms chose that moment to make their objections to our presence in their territory very clear.

— 51-

“Worms, Colonel Riggs! Zillions of ‘em!”

I heard the override shout in my headset, it came in over the command channel without the speaker identifying himself. It had to be one of my drill-tank pilots, I figured. This calculation proved correct, as I heard the drill-tank farthest up the line, the one I had sent into the tunnel first, begin firing. Rather than the steady pulsing beam of the drill, which was built to burn rock a few feet from the nosecone of the tank, the beam unit could be focused further forward to be used as a short-range weapon.

“Report!” I shouted, running now toward the front of our column. Heavy footsteps behind me indicated Kwon was right on my heels. “Is that you, Yamada? Specify enemy contact.”

More firing erupted ahead of me. I thought it was coming from the second drill-tank in line.

“Broken through-into some kind of chamber,” came the response. His labored breath blew over the microphone. “This is Major Yamada, lead tank, reporting.”

“All tanks, stop drilling,” I ordered. “Withdraw into the main tunnel. We’ve made a breakthrough.”

“They’ve got something big they are rolling up, sir. I can’t focus that far back.”

I grimaced. Out of range? That indicated Yamada had opened up a seriously large chamber. The tank’s nosecone weapon should be able to effectively strike at a range of at least two hundred yards.

I arrived, puffing and pushing past a clot of marines. They were trying to support the drill-tank, but couldn’t get around it in the narrow, freshly-bored tunnel. Yamada was backing out, and marines were dodging to get out of the way. He never made it, however. I heard a heavy thump, then the front of the tank exploded. It had been hit by a shell of some kind and knocked out.

My little Nano tanks were deadly at range, but they were not heavily-armored. I’d always known that if they were hit by something serious, their two inches of front-facing nanite armor would fold inward like cardboard.

“Yamada?” I shouted, but there was no response. He was probably dead in there.

I switched my voice-out to local, and shouted at the men around me. “Grab this thing and pull it back. We can’t let them have time to organize and attack.”

A dozen powerful hands gripped the tank anyway we could. Normally, Nano machines were smooth and rounded in every dimension. This one had been hit, however, and looked like a splashed mass of metal. Frozen with flanges sticking out in every direction, I could tell the brainbox had been hit. The nanites had no instructions, and so held their chains where the enemy shell had left them.

Another thump sounded. “Duck!” I shouted.

The second shell struck the mass of the drill-tank. The dead hulk bucked backward, pushing me off my feet. More nanite metal splashed everywhere, some of it burning. Whatever they were firing at us, it was incendiary. Gouts of molten metal twisted in the air and crawled on the tunnel floor as if alive-in a way, I supposed that it was. The squirming metal rained back into the tunnel where the marines and the surviving drill-tanks had assembled, pooling up into beads on the floor. The nanite droplets fell amongst us and sounded like handfuls of thrown coins.

“Heave!” I shouted, climbing to my feet, grabbing the wrecked tank with both gloved fists and pulling hard. More marines helped, including Kwon with his ham-sized fists. The tank moved. A grating sound indicated some success. The metal flanges scraped the smoking sides of the tunnel.

“All together now,” roared Kwon, “On three-one, two, THREE!”

We all heaved and the tank ripped loose like a bad tooth. Screeching, it came out of the tunnel like a nail being pulled out of a board. Roaring, we kept pulling, dragging it rapidly. Within thirty seconds, we had it out in the main tunnel, and we could see what it was we faced.

I saw nothing, at first glance. The tunnel was pitch-black. There were no Worms, or anything else. Great, I thought. They were resetting their ambush.

Pulling my head back so a sniper couldn’t take me out, I signaled my men to take cover. We stood on either side of the tunnel, hugging the walls. I breathed hard for a few seconds, trying to think. All we’d managed to do is open up a flank for ourselves. We had over five miles to go to get to the center of this Mountain-and that was only counting straight, horizontal space. We were in a three-dimensional fight now. We could go up or down, and so could they. I had no doubt this mountain was riddled with traps and tricks and the Worms were busy making more every second, now that they knew which direction we were coming from and where we were headed. They would whittle us down, making us pay for every advance. At this rate, it would be a month and countless dead before we could reach the goal. The trouble with that was, I didn’t have countless men-I didn’t have a month, either.

I looked ahead down the main tunnel. Should I just press ahead and fight our way through whatever they had planned for us on the main route? Or should we fight our way into this narrow side passage and try to do the unexpected? After about a minute of hard thinking, I decided to punt and feel my way through the situation. We’d give the Worms something to think about and see how they wanted to play it.

“Drill-tanks, I need two more units up here. Drill me two more holes, right next to this one. I want you hiding on either side of this shaft. If the Worms rush through to this tunnel, you will break through and hit their flanks.”

The drill-tanks rolled up and began working on the walls. I called for my sensor unit officer. Lieutenant Chen came up, dragging her wheeled equipment behind her. She set it up at a safe distance, aimed the pick-up nubs at the walls and worked the interface.

“I can’t see past these thick walls. The material is very dense.”

“I gathered that,” I said.

“The density drops off, however, about fifty feet in. I can’t tell what’s there, only a few shadowy contacts are registering. But the echoes indicate lower density. It could be a cavity, or low-pressure material. Something about as thick as sawdust.”

“Or Worm-meat,” I suggested.

Chen nodded after a moment. “Could be.”

“Sir,” said Kwon, lumbering up to me. “There’s something going on inside the drilled tunnel.”

I trotted to the mouth of the tunnel that led, reportedly, to a zillion Worms. I waved my hands for quiet and ordered the drill-tanks to idle. Steam wisped and churned. A choking cloud of vaporized rock clung to the ceiling. We waited, quietly.

I heard something then, after turning up the exterior pickups on my suit. Kwon voiced my own thoughts, having heard it as well.

“Something-slithering, sir,” he said behind me.

I waved for him to shut up. For once, he did. We all waited. Something slithered closer.

The unseen Worm made a final rush as we held back quietly. I was stunned when I saw it come out of the tunnel. It was huge. This was no twelve-foot baby Worm. This was a granddaddy, a titan of a Worm. It reared immediately and the two guns on its sides spoke. Marines tried to scatter, but it was too late.

Double thumps sounded-except at this close range, they were booms not thumps. Incendiary shells fired independently into my clumped together troops at close range. Blood, bone and scraps of gear exploded, leaving black marks on the hard, ribbed floor of the great tunnel.
