As Chief and Miller reached the bottom of the cliff they immediately threw their backs against a wall, making sure that they couldn't be seen by a passing Nightmare Brute who looked to their location for a second before continuing on, a large red crystal being held in his arms.

The second the Brute turned a corner Chief and Miller stepped out from behind the wall and looked to both ends of the hallway. "Which way should we go, left or right?" Miller asked.

"From what I saw up there going left will lead us to the outer edges of this facility, right should take us deeper into the complex and to the core of the operation, that's where we want to get to." Cheif explained.

"Alright, right it is."

Chief nodded and began walking forward with his battle rifle raised, ready for any enemy that would suddenly appear. Looking to his minimap he just saw a screen full of red dots. 'Minimap is gonna be useless here Marcus, too many enemies in other halls and floors.'

Chief shook his head and pressed onward, peeking over the end of a wall to look down the next hallway, seeing two changelings with two Nightmare drones. As the two waited for the four enemies to walk away they overheard their conversation.

"So when you enter our bodies we become stronger?" One of the changeling drones asked.

"Yes...we can grant you strength and power, if you allow us to fuse with you." One of the Nightmare drones answered.

"Well come on then, fuse with us already!"

"They're making a mistake." Chief looked to Milker who held a saddened expression. "Nightmares don't fuse with other beings, they possess them and use their bodies as vessels to bring destruction and suffering. Those changelings are throwing their lives away, they will feel nothing but excruciating pain while they are possessed and their souls will only be used to fuel the Nightmares."

'Marcus, kill them before they can fuse!' Eris cried. 'Don't let them suffer like that!'

"I can't Eris, it'll give away our positi-"

'JUST DO IT YOU IDIOT!!!'

Rolling his eyes Chief jumped out from his cover and opened fire on the Nightmare drones, landing two shots in their heads causing them to turn into a puff of purple smoke before forming purple orbs. Chief then aimed at the two charging changelings but decided to not waste his bullets, instead he let them get close enough and then knocked one on the head with the butt of his rifle and punched the others head clean off, causing drops of green blood to land in his armour as the head was thrown up into the air.

Miller stepped out, stared at the bodies and then sighed in relief. "At least they didn't have to suffer...thank you Marcus."

"You're welcome, now let's get going."

Miller grabbed the two orbs and tossed them into a small purple portal before they continued on, performing stealth kills when they came across other hostiles, although sneaking up on an enemy proved difficult for Chief as he couldn't take a step without his heavy armour causing the enemy to hear his footsteps.

Soon they came to the main mining area and hid behind a large rock, watching the changelings and Nightmares dig into the earth and extract the red crystals from within the stone, each of the gems holding Apocalypse Magic within them, just waiting to be absorbed.

"So, what do we do now?" Miller asked.

"Now, we destroy this place with some well placed explosives." Chief answered as he held up an explosive charge.

"Bad idea, if all of this Apocalypse Magic explodes it will give off an explosion that would amount to one hundred nukes being dropped on one location." Miller countered as he shook his head. "It would also corrupt this world, making it completely uninhabitable."

"So no explosives, got it." Chief said quietly before putting away the charge. "You got any ideas?"

"Hey! Over there!" They heard a Nightmare drone call out while pointing at them. All of the miners and other hostiles looked towards them with a snarl, ready to take them on full force.

"To be honest we should have probably chosen a more secure hiding place." Miller commented dryly before growing four black tendrils out of his back and summoning two black blades while taking a fighting stance, Chief holding up his fists as they stood back to back.

As the horde of creatures began to close in on them they started to sweat, heavily outnumbered and outgunned, facing enemies that were armed literally to the teeth in some cases. As the first changeling was about to pounce they all stopped as an echoed voice spoke all around them. "Stop your advance...I want to meet them face to face."

The hostiles all growled in anger before they were teleported away.

The two found themselves in a large circular room, the floor glowing blue and being the only source of light other than the half of the rooms walls which were covered in screens that showed various parts of the facility. "This must be the overseers station." Miller spoke to himself.

"Well well well, what do we have here?" They looked up to see a shadowed figure floating above them in the dark. "The traitor and the knight in dull armour."

Upon further inspection from Chief, he noticed that the being was not floating but was being held up by very long limps stabbed into the walls around it.

The being descended into the light, revealing itself. It was a Nightmare, but was far different from the rest. It had very long and spiky hair which caped his back, much like a hedgehogs spines. It was a slight dark shade of purple, unlike the very dark purple drones. It had long spider-like limps growing out of its back and it held a smug grin.

"Nightmare Beta?" Miller asked in confusion. "I thought Nightmare Alpha was in charge of this facility!"

Beta chuckled darkly. "Well traitor, my brother Alpha is a bit busy with a certain metal hedgehog right now, so I am standing in for him." Beta then turned his attention towards Chief. "Ah, Marcus. How wonderful it is to finally meet you in person. It's such an honour to be in the presence of someone who slaughtered hundreds all those centuries ago!"

Beta shot one of his spider limbs towards Chief who jumped out of the way and aimed his rifle before pulling the trigger, only to watch as the bullets were effortlessly smacked away by the higher Nightmare.

"It's been a long day and I don't think any of us are in the mood to talk, so let's just get this battle started." Beta smirked before charging forward.
