Her heart was racing, her cold grey blood coursing through every vein, every fiber of her being as she knew what was about to happen.

Two blackened Leaper's came from around the corners, she was about to blow them away with her Force gun but, Applebloom and Isaac had already killed them.

As they ran, Isaac was almost hit with a ball of acid.

"Puke on that fucker!" He yelled triumphantly.

"Scootaloo! Throw me up!" Sweetiebelle yelled over the noise.

She wrapped a tentacle around her friend and threw her up.

They ran, Scootaloo catching a glimpse of two Lurker's being shredded before going through the first door.

The room was dark, had white lines on the floor outlining the coagulated blood pools, a small railed off area to the left and the door farther to the right ahead.

As they continued to run, two blackened Slasher's came out followed by a black Puker.

Scootaloo burned the Puker before firing off her alternate fire of her Force gun. She obliterated the second Slasher as Isaac and Applebloom decimated the first with Line rack's and Pulse rifle bullets.

They all quickly reloaded and ran out.

When the door opened, a blackened Leaper and Puker were waiting.

Scootaloo grabbed the Leaper, and threw it at the Puker before firing off an explosive canister.

They ran to the next set of doors, Applebloom stayed back momentarily to keep the other Necromorph's at bay with her Plasma cutter. Satisfied, she went back in and saw Isaac shoot a grenade at a Puker climbing up.

Scootaloo Swung out with her tentacles and pinned the Slasher to the wall before sticking the nozzle of her flame thrower directly into its mouth and pulled the trigger.

She kept doing it; she kept the trigger down until the fire was coming out from its chest. They reloaded again and went to the next door after moving a cabinet.

Scootaloo looked back, the room was still the same as the other one only the rails were to the right and there were a few stasis canisters in a corner. She grabbed one and went out with the other engineer's.

"Move!" She yelled.

Her friends moved as she chucked the stasis canister over them and shot it above the other Necromorph's in the way.

"Sweetiebelle! Come on! We need you in here!" Isaac yelled over his comm as Scootaloo opened the door.

"Open the door and go in, I'll slide under!" She commanded.

She and her friend’s went in, shortly after Scootaloo heard the sound of snapping cables and shortly before the door closed. Sweetiebelle came rolling in and struck a bad-flank pose.

"Now that's just showing off." Isaac said.

The room was dark but had a brownish light coming from the poorly cleaned windows. Rusted pipes lined the side and unsteady metal crisscrossed under foot.

"Whatever," she rolled her eyes. "How are we all doing on ammo? I barely used any."

"I might need more petroleum for my Flamethrower." Scootaloo said. "And maybe some Force energy? I'm not sure." She turned to Isaac.

"I'm almost out on Pulse rifle ammo." Isaac said. "I have two clips left and one grenade."

"Ah'm almost out of Plasma energy and Line racks." Applebloom pouted. "Ah guess ah'm still good."

Scootaloo watched her friend stat towards the lift. "Well, we'd better get going." Sweetiebelle said going to the lift. "The Marker isn't going to destroy itself, now is it?"

"Come on you two, we've got some deconstruction to do." Isaac said going onto the lift followed shortly by the other two crusaders.

Scootaloo huffed inwardly, but remained quiet as she went.

She glanced to the side as Sweetiebelle's ears perked up.

"Guess who’s back." She said.

"Dammit..." Isaac sighed. "Do we even want to know where?"

'What he said.' She thought.

"Somewhere inside there." Sweetiebelle pointed at the door ahead.

Scootaloo hid a frown and a whine but kept her stoic expression like a royal guard.

"Then, let's see if we can't throw it off our trail." Isaac said getting out his Line gun.

"Well show this thing why ya don't mess with the Apple's." Applebloom said taking out her Pulse rifle.

"It may not have a soul, but I don't have a heart for anything like that." Scootaloo said taking out her Force gun.

They all proceeded slowly, weapons aimed at the door ahead. Waiting to see it come open and a pair of blades to shred them to bits.

Isaac opened the door and peered in, lowered his weapon and took the first step inside.

"Are you sure-" He was saying but was cut off when the vent was ripped apart.

The Ubermorph looked at Isaac, blinked and raised one of its arms.

Scootaloo sent it into the wall, holding it there while Applebloom got rid of the fuse.

[How strong are you!?] She thought fervently. She looked to the side and saw the door was open. She let go and ran in with the others.

She mentally face-hooved when she saw they ran into a dead-end, literally, that's how it looked like it was going to end for them.

They all looked back and saw the Ubermorph coming in.

"Hang on, I've got an idea. I just need to check some blue prints." Scootaloo said, tapping away furiously on her screen.

she only focused on the screen all other noise was mainly static to her, her eyes narrowed, ears splayed back as she bit her lip, tapping away through all the blue-prints.

She heard Applebloom and Sweetiebelle cheer. "Whoo hoo, go Isaac." Scootaloo twirled a hoof around in mild interest before her eyes lit up. "I've got it! We need to throw it into the vent!" She yelled excitedly.

"Alright," Isaac groaned, holding back a pair of blades. "How do we turn it around? And, help goddammit!" He yelled.

"Isaac step back and go behind it, I need you to punch it!" Sweetiebelle yelled. "I'll do the rest!"

'What are you... doing...?' She thought as she saw her friends horn and Isaac's fist light up. 'Smart, transferring momentum and energy into a small area, therefore increasing damage.'

He groaned once and threw the blades down before turning around. Her went behind it and raised a fist. He looked at her and saw her horn glowing, out of the corner of his eye, he saw his own fist light up too.

"Now! Punch it!" She yelled.

He swung forward, and when his fist touched the Ubermorph, his fist flashed before a small explosion came from it and sent the Ubermorph back towards the vent.

"Ow... ow... this really hurts." He said cradling his hand. "It might be sprained at best."

'I bet it does hurt.' She thought. She looked over and saw the Ubermorph get up. 'Oh come on!'

Applebloom ran first and rammed into it, making it stagger back a few steps. She retreated and let Sweetiebelle go next. She did the same and retreated.

Scootaloo shot her Force gun using the alternate fire mode and sent it right at the grate. It was only hanging on by its blades. Slowly, Isaac made his way over, a smile on his face.

He raised one boot up and kicked it down, roaring furiously as it went down.

"This is Sparta!" He yelled. He turned back to see the crusaders give him questioning looks. "Hey, if I'm going to die in a few moments, I might as well have some fun."

'weird. I wonder what that was from?'

They shrugged before going around the corner, himself quickly following. As they went out to the catwalk, they didn't hear or see a single blade dig into the side and raise its owner up.

The Marker.

"So, this is it." Sweetiebelle said.

"Eeyup." Applebloom said.

"The end game." Scootaloo said. 'That was cliché.'

"Our end, that is. And its." Isaac said walking forward.

When they were almost at the light that was Nicole, a spike shot out and went through Isaac's shoulder. With a grunt of pain, he slowly pulled it out.

"The research we put in that Marker, is worth every life lost." A half Kentucky-fried half normal Tiedmann said limping forward with a Javelin gun.

The crusaders stared, angered but also scared and let the scene play out for themselves.

'Come on Isaac! You can be beat by some crispy moron!' She thought. She saw Isaac disarm Tiedmann and motioned for Sweetiebelle to go over. 'This isn't going to be pretty by the look on her muzzle...'

"What... are you going to... do to me?" He wheezed.

"Give you a taste of your own medicine." She said before her horn sprouted out from her head on a stalk and rammed into his skull.

'Eww... that's just wrong.'

Instead of the desired effect, he was still alive. Only, he was changing, healing too.

A small stub came out from his fore-head, his hands and feet melded together by their own digits. His face became longer, his sharper teeth flattened and his eyes became monstrously huge. When it ended, he was covered in a coat of brown fur.

"What... what did you do to me!?" He yelled shocked and furious.

'wow. Awesome.'

"Not what I intended, but I can make this work." She said.

A Drag Tentacle came out from her back, grabbed Tiedmane and threw him over the edge, into the Necromorph's.

They all watched as he went down. When the crusaders looked back at Isaac, he was stock still, the veins under his skin turning black.

"Isaac...? Where's Nicole?" Applebloom asked. "Isaac?"

"Hang on, I think I know what's happening." Scootaloo said putting a tentacle into his neck. "He's... he's inside his own mind."

"Should we help him?" Sweetiebelle asked.

"I don't- agh!" She cried. "Yes! We should definitely help him!"

"How though? It's not like we can just go in ourselves?" Applebloom said.

"Oh yes we can!" Scootaloo said. "Remember how I said I could make a mental link? But I shouldn't because I might kill you all? Well," Her tentacles connected to her friends. "Let's hope it doesn't happen."

Scootaloo saw nothing but small neurons and finally a grotesque world. It was the same as the Marker's light, patches of land were scattered everywhere, and in the middle of the one they were on, was Isaac.

"Fuck you!... And fuck your Marker!" He yelled at the old Nicole.
