In abandoned tunnels beneath Colorado

Deep in the abandoned tunnels beneath Colorado, three people, two older looking men and a young girl, quietly made their way through the darkness. Before they even reached the halfway point, the girl accidently knocked a large rock into a hole, making a loud crash that echoed through the tunnel. Then, the trio heard a sound that made the blood in the veins of the only two in the group that actually consider themselves human to freeze solid.

"Clickers!" the girl whispered worryingly, "What do we do, Joel?"

The man she spoke to looked around, "I don't know. Alan, how many are there?"

The third member of the group stepped forward and stared into the blackness, where the sound was coming from. The other two members knew that, while they couldn't see a thing, Alan would be able to see the infected creatures as if they were in broad daylight.

After a few seconds of staring, Alan rubbed his dark hair hidden by his grey hood and sighed, "There's a shit ton of 'em. Clickers and runners and they're heading this way. I count around thirty of the ugly fuckers."

"Shit, what'll we do, Joel?" the girl asked.

"I don't know, Ellie," Joel said, looking around, "We don't have nearly enough ammo to take them on and I don't see a way we can sneak around."

"I see what we can do," Alan said, pointing at an abandoned bus, "You two take the ladder on the back and get on the roof of the bus. When you do, lie down as flat as you can and keep quiet. I'll take care of these creeps."

"You sure you can take that many?" Joel asked.

"Guess we'll find out," Alan said, "Now hurry up."

The two others quickly and quietly did as Alan told them to. Once they were on top of the bus, Alan, with seemingly no effort, ripped the ladder off. Almost the instant that he did this, the first of the runners burst out of the darkness. Alan's arms writhed in black tendrils, breaking down and reforming into large claws with the metallic blades glittering in the darkness.

"Let's see how much these cordyceps-infected fucks like a little taste of the Blacklight virus!" he yelled as he charged at the infected hordes.
