In the UAC facility of the Lazarus Labs, Hunter and Pink decided to split ways so Pinky will take the two elite guards with her and go and secure half the facility by going to the experimental rooms, seeing just how much damage did the elites did to the place. Hunter will go alone through the facility to go find the Master Chief, trying to catch up to him while he goes further down where he might find something that will become a challenge to him.
When Pinky and the two guards arrive in the part of the experimental rooms, she ends up arriving down this corridor seeing some dead marines on the ground, all devoured and eaten even though they are dead. They slowly head through with caution knowing that whatever did them can't be far and they were right because just when they enter the next room, they discover something they have never seen before in their lives, since she is here she would have to fight like hell in order to survive against these demons that have been broken out of their pods and cages.
When they arrived in the next room they see these tall looking creatures crouching down devouring someone, devouring an elite zealot on the ground after they took it out. Once Pinky and the guards took aim these creatures looks towards them, seeing these tall looking imps the size of a Spartan, having a lot of these eyes and lets off a screech then charges towards them. Quickly the three fires all out at them, blasting them back and killing them instantly, seeing their bodies disintegrate on death before they hit the ground.
"What the hell were they?!" The elite guard said holding his machinegun
"Do I look like someone I know…" She looks to him "As long as they have a head, it's a weakness." She turns to the side seeing another imp landing on the ground, coming from the ceiling she quickly fires her plasma rounds killing it before it got close to them. "Let's move!"
They start moving further inside the experimental labs however the demons have already been released, everyone inside is all killed and teared apart by the demons and are probably scattered elsewhere but with only fifty pods broken through, it will not be enough to actually kill everyone here.
Elsewhere the Master Chief finally arrives through room protected by a strong door, the top of the door shows a writing saying 'Dark Matter Research'. Chief was able to unlock it and got on through however just when he walked right through the door he started to hear something, quickly turning back and aiming his double barrel, looking out at the hallways but no sign of anything so he started moving backwards then looks forward when he stood in the center, trying to find anything useful here.
"It seems that the UAC has been doing some research on a lot of stuff here about the hell gate." Cortana said while Chief looks around "Hold on Chief, I'm picking strong dark matter energy coming on the door on your right."
Chief ignores the computers and the other stuff in this room but he got a look at this small little container, holding this dark matter energy inside of it, it was just lying there on the table but he will look away and walks in the door and tries to unlock it but that didn't go well. Since he can't access the door he turns back and tries to plug Cortana inside a console, seeing if she can unlock the door.
"How far are we to the hell gate?" Chief asks her while she takes the controls
"We would have to go through a few more doors, we are almost there Chief… But Chief, what exactly did you see in 'Hell'?"
"The man in the armour that we saw in Hayden's office… I saw him Cortana, he was the Doom Slayer and I saw him kill a lot of monsters in this vision I saw."
"How did it end?"
"He was pulled into a trap and got sealed away."
"Do you think that Helix Stone wanted you to find him?"
"Maybe, but right now I have to stop someone –"
Just when he finished his sentence this demon comes running through the side, hitting against the wall and got a look towards Chief. Chief turns back when he heard the noise, seeing this demon letting off a roar when it comes charging towards him. He aims his double barrel and fires when it got closer, blasting right through the face and top of this demon and sends it falling to the ground right in front of him.
"What the hell was that?"
"Do you got the door opened?" Chief asks while reloading his double barrel, watching this demon fade away then looks at the front door.
"I'm almost…. Got it."
When the door finally opened, Chief pulled Cortana out of the console then quickly moved inside the other room while watching the front door, once inside the door will close and Chief will turn back seeing this square room with something in the center of it, having walls around it and only one door to walk inside but there's two windows on both sides of this small room in the middle. Chief will look through seeing this weapon inside this dark matter energy and these rods around them seem to be containing the dark matter energy. Chief walks over to the door of it then looks on the other side seeing another door, probably leads to the rest of the research of the dark matter energy but he ignores that for now and looks at the door trying to unlock it.
"Can I get through there?"
"I'm sure your armour can withstand that dark matter energy, just get the gun and get out of there."
"Alright." He unlocks the door and walks through.
When he got inside he noticed that the dark matter energy will end up being absorbed from the rods as they keep floating around it, once the rods have absorbed all the energy, all that was left of this weapon that just floats there, spinning around slowly for Chief to just pick it up. This large weapon contains dark matter energy in this container that shows on the top of the gun, the same container he saw in the other room, if he could find more of this dark matter energy he can use it but since there's only two containers then that's how many shots he can use.
When Chief walks out of there he will get contact by Spartan Hunter. "Master Chief do you read me…" Chief ends up getting some static on his coms "I'm heading to you…. UNSC forces…. Contact –"
"Hunter this is Sierra-One-One-Seven, can you read me?" He tries to respond to her while walking to the exit door, hearing nothing. "Hunter can you read?"
"We should get out of this room, maybe we can talk to her outside of this field."
"Right."
When Chief walks out of there, the UNSC finally arrived through the gaps of where the covenant landed through. Spartans will be deployed down here first then the marines, heading on through and try to deal with any containments and to deal with the UAC. The Spartans will order all personnel to retreat to the elevator entrance where the team on the surface tries to dig a way through to get them all out of there, the Spartans and the UAC marines will go off elsewhere to go to the Lazarus Labs and other places further underground to find anyone else down there, trying to get everyone out of here but the scientists try to get their hands on any stuff that's valuable because they don't want all their work go to waste. They take some hard drives, laptops, artefacts and anything else they can carry then will make their way to the elevator room.
Spartan Reaper and a few handful of Spartans will take the elevator and head down the way where Chief took, they will also get the company of eight marines from another elevator heading down to the Lazarus Labs. They will have to split up to get more ground so the marines and the Spartans will go to the experimental labs to help Pinky while Reaper and two Spartans will join him to go to the hell gate, unknown that Chief and Hunter are making their way towards it but they might be falling into a trap.
Elsewhere back to Pinky, she and one elite guard made it to the experimental room, firing off plasma round through this hell knight while moving back. The elite guard runs the other way while firing rounds to the side of the hell knight but he didn't see that spectre behind him, tackling him to the ground and ripping through his armour, biting through his flesh and giving him unimaginable pain. Pinky would see that and kept firing until that hell knight went down on one knee, quickly she runs up to it and lays two punches on both sides, the second punch smashed through the hell knight then would turn towards the spectre ready to fire when it raises its head towards her.
"What the hell?" She mumbles to herself then was about to pull the trigger however she felt another presence near her, turning her head seeing another spectre to the side of her. "Oh shit…"
She aims her gun to the one next to her however it ends up tackling her to the ground, tossing her weapon away from her reach. She struggles as it tries to bite her and she tries to get her combat knife, she ends up stabbing it through the belly of that spectre but then the other one joins in by biting her arm hard, penetrating through her arm and the one on top of her continues attacking and since she can't hold that one with one arm she can't hold the both of them, they will end up eating the hell out of her while she screams out loud and no one to help her escape from this.
Chief and Hunter continues moving through this hallway and was about to get into this room and discovers a few explosions going off, seeing this strange monster called a revenant comes forth into the room. When it looks towards them it started taking flight, firing rockets at them while Hunter runs forward firing her vortex rifle at it but Chief moves backwards firing his Chaingun at the revenant while it flies to the side then lands.
The revenant keeps firing and soon another one comes in. Hunter switches to her shotgun and started firing rounds at it while it flies through while Chief kept firing at the revenant until finally it went down, he turns to the other and started firing at the other one, helping Hunter penetrate through its chest but Hunter uses her boost jump in the air, getting closer to lay a punch across the face, sending it falling to the ground then ends it with a curb stomp on its face.
Hunter looks back to Chief "Let's go –" She suddenly takes a green fireball from the arm from that door, hitting her left arm and sending her falling to the ground.
Chief places the Chaingun on the ground and runs at her while switching to the double barrel "Hunter!"
Before he got close to her another demon will come forth from that door way, causing him to stop and see this new one standing before him. A large baron of hell comes forth bringing fear to the two Spartans, having the ground shake as it walks forth and lets off a screech at Chief while Hunter slowly crawls back then tries getting back up while firing her handgun at it to get its attention. Chief would quickly fire his double barrel at it, hitting its arm but it still goes after Hunter by jumping in the air and slamming hard on her back, sending her back to the ground and breaks through her back of her armour, that stomp of the hooves of that baron broke through her armour and damaged her spine badly. The baron turns to Chief then throws a green fireball at him while he moves to the side, firing his double barrel again while it comes leaping at him and slams to the ground close to him but he rolled out of the way, getting his back towards Hunter and finally switching to a bigger weapon and that's the dark matter gun.
"Let's see how this goes." He said while the baron turns towards him letting a screech at him.
He fires that gun, sending this strange dark matter rift through the air slowly and ends up going through the baron however it's causing major damage from the inside and out. Once that rift goes through the baron and hits the wall behind it, the rift explodes and sends this dark matter blast across the area consuming the baron and causing some parts of the demon to be removed before it could fall to the ground, falling at the feet of the Master Chief.
Chief looks at the gun then looks down at the baron. "You know… I think the title 'demon' doesn't suit you here anymore." Cortana said watching that baron fading to nothing.
"Yeah…" He was about to reload but he remembered something, turning back and running towards Hunter while she still lies there on the ground. He drops the gun next to her and turns her around, having her facing Chief as he crouches there looking down at her. "Hunter…."
She coughs through her helmet and her voice became weak. "Chief… Go on ahead…. Stop him… Before he releases the hell gate…"
"Hunter…."
"I'll be ok… We'll be ok with you here…" She slowly raises her hand to him, ended up poking at his visor before lowering her hand down.
Chief was force to slowly put her down then gets back up off the ground, taking her shotgun then takes his dark matter gun and reloads it with the last dark matter energy he has. He quickly makes his way through the door, making his way to the hell gate and running as fast as he can, holding that shotgun ready to finally get this over with once and for all.
In the room where the hell gate is, showing this wide room with the front of it showing the gate that has the shape of a wide hexagon but it shows nothing on the inside, just the border lines and this ramp in front of it. There is a window facing the gate that shows a control room where the demon was able to get inside and placed an accumulator inside a cylinder gap hole where it needs to be placed, turning on the power here and slowly sending that argent energy through the gate so he can create the rift hole. Once he activated the hell gate he quickly smashes the right equipment, making sure no one disables it then would leave that room and makes his way to the portal directly by going through this opened blast door and goes walking right in front of it, watching the argent energy pouring out on the borders of this gate until it becomes a rift.
"At long last… The hell gate…" He said walking up the ramp watching the gate slowly opens up. "Finally…"
He turns back when he sensed someone coming down the hallway and running into the room, seeing the Master Chief yet again but face to face. Just when he runs in the room seeing the demon first time, he got caught in a little flashback yet again of that time when he was in the mind of the Doom Slayer, seeing the same one that sealed him away.
"Master Chief…."
Chief quickly took aim at his face then fired his shotgun, firing at his face and causing his head to turn back and his upper body turning to the side. When Chief lowered his gun and waits for it to look back to him, he sees the demon looking back to him, showing the mark he did to him. The demon shows this hole through his right eye where Chief fired that shell, Chief will also see that his eye slowly regenerates itself until it's back to what it was before. Chief was about to quickly switch to his dark matter gun but it was the demons turn to attack, quickly raising his hand and sending Chief flying back and smacking against the window, he couldn't move or do anything while this demon holds him where he is.
"The Master Chief… At long last we meet." The demon said walking closer to him "I have to admit I was scared at first when I saw you, you do remind me of someone I know…" He stands in front of him looking up at him while still having his hand aiming at him to hold him.
"The Doom Slay –"
"Do not speak of his name!" He ends up slowly tightening the grip on Chief, feeling like he's being crushed by a large hand. "That man is gone… Because of him he ruined everything… He ruined every work I have done for my master, stopping the breaches, killing the Titan, murdering my hell priests and killing the lord of terror. Now he is sealed away forever."
"…"
"After I sealed him away I finally found a way to get back into the galaxy, but I was delayed yet again by the blasted Prometheans. They locked me inside a prison, but it's a good thing that these 'Covenant' are so stupid enough to release me, all I have to do is play my part and be a Promethean, then they would help me attack Argent so I can finally return back to hell."
The demon lowers his hand, he stopped tightening up but he was still stuck up there. The demon will walk back on the ramp when the portal finally opens up, showing this orange energy swirling around like a vortex. Once it was ready he started walking up closer to the portal then looks back to Chief while he just watches and can't do anything.
"The Awakening of the hell gate has started… The Apocalypse… Will soon to happen… And you Master Chief, you will not get in my way. You may resemble that 'Man' but you will never become someone like him, just a false man."
He raises his hand in front of him again, getting Chief off the wall and gets him floating forward for a bit, not knowing that there's a blue vortex opening up behind him against the window. "Now meet my Harbinger of Doom." He pushes his hand forward sending Chief flying back and sending him through that vortex.
Chief gets sent elsewhere, appearing somewhere so quickly in just half a second. He ends up appearing somewhere else in the facility, landing hard on the ground and getting this strange orange electrical energy for only a while. As he lies there, Cortana calls to him but Chief can only hear static for a while. Kept hearing static when he slowly tries to get up but when that electrical energy fades, he could finally hear her.
"John.. Come on, get up!"
Chief slowly gets back up. "Cortana…"
"John we have to go, that guy opened the hell gate. He's going to bring the whole damn apocalypse upon this facility."
"The apocalypse… It hasn't happened yet…" He looks around seeing he's in this huge square room. "Where are we…"
"Uhm… John… We are not alone."
This large slam causing the whole area in this room to shake will be heard from behind them, when Chief quickly takes his double barrel and turns around seeing the biggest demon he has ever seen. This large Balgar demon stands there looking down at him, a demon with a metallic leg and arm, the arm was replaced with a large cannon that's unknown on what will be firing out of it. It lets off a roar down at him while he slowly moves backwards, lowering the double barrel while that Cyberdemon raises it's cannon at him ready to shoot.
