"Eagle-Nine to Rhino Squad… Can anyone read me? This is Eagle-Nine, calling any UAC marines on the ground, can anyone respond?"

"Don't bother." The co-pilot said "If there still alive then we have to find out when they get to the surface."

"The problem is that they are almost out of time." The pilot sighs under his helmet "Where the hell is everyone?" He looks on the window in front of him, looking down and seeing some demons pressing the attack inside the base "There's a lot of demons down there…."

"We did ran out of there you know…" The co-pilot said when looking out at his window, seeing a Cacodemon in the distance. He looks back to the Chaingunner "Target the Cacodemons."

Meanwhile, inside the facility, the marines got what they wanted and are already preparing to make their move back to the surface. The sergeant was just standing in the hallway with twelve marines behind him, having two of them carrying a large container that has the Argent Core inside of it. He would stand there trying to contact the men on the surface, hearing on static on the radio inside his visor.

"Eagle-Nine can you please respond, what's your situation up there?"

"Sarge look out!" One of the marines said, aiming his assault rifle towards the doorway, seeing a couple of imps storming inside the room.

Three marines took aim at the imps and open fire, taking out several imps that came through that door, killing them before they could throw a fireball at them. Once they were dead, they quickly act, making their move down the doorway and through some corridors, fighting off against the demons while they protect the precious cargo.

The marines make their way to the surface while elsewhere, Lauren and Randall teams up for once as they make their way up a few stairs and into a wide room, seeing the whole room is in ruins but they stand at the ready. Both the two looks at one another while Randall carries an assault rifle and Lauren carrying her shotgun, still not trusting one another but it is up to them to find the team. The only reason why Doom is not with them is that he is busy inside that room taking care of the demons inside the pods.

Doom was busy with a Revenant that was release from its pod, seeing him using his boost jump to punch its chest, sending it onto the ground so he could punch it again through the head. Doom looks back and aims his double barrel, blowing a hole through the chest of the hell knight, getting him to kick the hell knight to send it onto the floor. He looks towards the Baron that came out first, seeing it lies there against the pod it was in before, having its left arm and a horn removed from its body before it disintegrates.

Back with Randall and Lauren, both kept their weapons aiming as they move through this place without causing any demon attacks. Lauren would speak to Randall, seeing that the area is clear for now, wanting to know about who that person was.

"Mind explaining what is a hunter is doing here?"

"Hey I'm just here because of him."

"Care to explain who he is?"

"You wouldn't believe me if I told you." He stops when he heard a noise behind him, getting him to look back to fire eight rounds through an imp.

Lauren looks back then looks forward, moving towards two other imps that came into the room, one throws a fireball at her while running, getting her to duck while firing three shells to remove the imps. She looks back to Randall as he aims his gun towards a doorway leading to a computer room, seeing him shooting at the demons inside that room.

Lauren looks forward and shoots another imp that came through the door; she also heard gunshots coming through the doorway she is facing. She soon discovers the marines coming through that doorway, seeing one of them aiming towards her and cause him to lower his weapon. He looks back to the other marines, signalling them to come on through and hold fire as they have friendlies in the room.

"Lauren!"

"Sir." She salutes to him then looks back to Randall as he comes over, causing the sergeant to turn his head to Randall while Lauren looks back to the sergeant. "Relax, he's here to help and he brought a friend with us."

"What's going on at the surface?" Sarge asks Lauren

"Sir, all I know is that there is an Archon of Hell on the surface, it chased Eagle-Nine out of the facility."

"Damnit…" He looks back to his marines who are staying their ground, defending the doorway and towards them as well. "Is there a way to get rid of that Archon of Hell?"

"Actually…" Randall spoke, causing the two to look towards him "The black Baron is dead."

"What!?" Both the sergeant and Lauren spoke at the same time. "Impossible!" Lauren said

"We killed it… It wasn't that hard."

He sighs and looks away for the moment while Lauren looks back to the sergeant "We need a way out of here, do we have what we came?"

"Yep." He looks back to the container "Now we just need a pickup."

"We have to get to the roof, sir." Lauren said "It is the only way for Eagle-Nine to find us, having a pickup outside is a bad idea."

"Plus it's overrun by the demons."

Sarge looks to Randall for the moment "You and I are going to have a talk later after this…" He looks back to Lauren "We go to the surface with the container."

"Yes sir." She turns around and moves forward, aiming her shotgun and goes off to take point to see if the area is clear.

"Hold on!" Randall runs after her, reloading his weapon and catches up to her when she walks down the pathway on the left.

Sergeant turns towards his men and orders them to move, getting the team to head on through with the cargo to take it to the rooftop, knowing that going outside is a bad idea. Both Randall and Lauren stays at the front, the team would stay around the cargo and defend it against the demons that comes through the doorways. They only fight off against a couple of imps, no signs of any big demons but surely, they will find some soon.

The whole team continue their move through the hallways, soon to see on the other side of the door lies a Mancubus approaching them. The Mancubus lets loose some flames through the room, causing the ones at the front to back away while they shoot towards the Mancubus. The team backs away while they shoot towards the Mancubus, hitting the chest while it moves forward and keeps shooting them. One of the marines who was holding the container takes a hit from that Mancubus, collapsing onto the floor and dropping the cargo, causing the marine behind him to help him up to grab a hold of the cargo again.

"We can't stay here!" The marine said who stood at the back, firing his assault rifle towards the demons that is coming around the corner. He suddenly takes a couple hits of the chest with a revenant's rockets, taking five hits before collapsing onto the floor.

"God damnit…"

As the Mancubus continues moving forward and keeps firing these orange energy balls towards them, causing them to avoid them so they could keep shooting. They were being pinned down by this demon and soon more demons would arrive behind them, causing so much trouble but luckily Doom at last shows up. Doom appeared behind the Mancubus, grabbing one of the tubes and pulls it off it and jumps back, watching the Mancubus explode after he pulled the tube, seeing a large chunk of the Mancubus removed.

The marines at the front stopped shooting after the Mancubus exploded, once the Mancubus disintegrated, Doom comes walking through, holding a Chaingun on his right hand and a grenade launcher on his left hand. He slowly raise his grenade launcher towards them for the moment, soon raising it up towards the top of the door behind them, shooting at the top of it and causing the door to close. The marines did crouch down when feeling that explosion, both Lauren and the sergeant looks back when they see the door closing before a Pinky came through the door.

The sergeant looks back towards Doom "Who the hell are you?"

"You don't want to know." Lauren said then looks towards Doom "Thanks for the help, you done killing demons?"

Doom points to himself with the grenade launcher to his chest then aims up at the ceiling, getting him to turn back and walks away while they stood there confused right now. "Can this guy even talk?" The sergeant asked while he walks away

"I think he's going to the roof." Randall said then looks to the sergeant "That means we should go outside, not on the roof."

"But there's demons out there." Lauren said

"Not for long." He looks forward and moves out

"Can somebody explain just what the hell is going on?" The sergeant said when looking to Lauren

"I am confused as you are sir." She looks to Randall while he runs off "But whatever this guy is, I suggest we play friendly to him, unless you want to have the same fate as that Mancubus."

"Yeah… Alright." He looks back to his marines "Alright we go outside, let's go!"

The marines got up and move forward, making their move outside where they will try to get to the middle of the base, shooting their way out of here against the demons while Doom was making his way to the rooftop, arm with an M79 grenade launcher and his Chaingun he took from a dead marine. When he made it to the roof, he walks over towards the edge of the roof, kicking a barrel off the roof and blowing up on impact, blowing up two Imps as they try to storm the inside.

Doom stands there looking out there with two hands to his Chaingun, soon looking as a Cacodemon shows up, it moves towards him and causing him to take aim and fire. His anti-piercing-rounds, penetrated through the skin, killing it quickly, sending the Cacodemon out of the sky. Doom aims his gun at the ground, spinning up and letting loose everything upon the demons, shooting every single bullet from that Chaingun, turning the gun left to the right, killing all the demons and wiping a lot of them out. All of those rounds made him kill eighteen Imps, three Hell Knights, one revenant, two Cacodemons and two Pinkies. After his Chaingun ran out of ammo, he simply drops it on the ground next to him and takes out that M79 grenade launcher, aiming it towards a Hell Knight and fired. He obliterated the Hell Knight with one hit, making him reload and aiming it to the left at a Revenant that is flying through the air, moving towards the roof but only to be stopped when Doom blown it out of the sky.

The marines finally made it outside, firing their way out of the facility but they did lose two marines in the process, they lost two thanks to a Lost Soul and a Hell Knight that got too close. The marines would make it outside where they notice that most of the area is clear, seeing that there is no sign of any demons left but they are further away. The sergeant would try to contact Eagle-Nine while both Randall and Lauren looks up towards Doom, seeing him standing on the edge but would jump down off there, landing hard on the ground but was all right on impact.

"So who the fucking hell are you people?" Lauren said, hands on hips when looking to Randall and Doom.

"You wouldn't believe me if I told you." Randall said when moving in front of her while Doom switches to a double barrel

"Just try me." She looks to his armoured arm "You're from the UAC but you are a deserter, why the hell are you with him and still helping us?"

"I only left because I learn the truth; the same thing goes to the others who have also left to join the hunters. I left for three reasons, one is to go out there to protect the people and not hide in our underground fortresses. The second is because of him." He points to Doom "He is the sole survivor of the Mars incident."

"Are you serious?"

The sergeant looks over when he heard he was a survivor of the Mars incident, getting him to walk over towards the three. "What's this about the Mars incident?"

"This man is Doom Slayer, the one we have been waiting for a long time."

"Doom Slayer?" He looks to Doom then to Randall "Don't make me laugh."

"And this is the third reason I really did leave the UAC."

"Doom Slayer as in the marine from the stories?" One of the marines spoke out, standing behind the four and got their attention "Yeah I heard of the story, didn't know it was true."

"It is true…" Randall said "This man can help change the war, he can end the demons. You guys and your advanced technologies haven't even made a dent to the demon army yet."

"That is about to changed." The sergeant said "We have a plan to get rid of a hell portal, that is why we came all this way to get this Argent Core."

"Yes well you will probably need this guy more than I do." Randall looks back to Doom "If you still wish to help the UAC, then I cannot waste any more time here. I have somewhere to go, that means… It is time that we depart ways here."

"Just where are you going?" Lauren asks

Randall looks back to Lauren "I'm going home, back home to Deimos."

"So your one of them…"

"Your part of that organisation?" The sergeant asks "Those renegade hunters."

"Is there a problem with that?"

"Yes there is, you men have caused too much trouble to the UAC, you may be fighting demons but you men of Deimos always end up attacking the UAC and stealing our weapons."

"That's because you damn people go too far. Do you honestly think you can win the war all by yourself?"

"Sir!" One of the marines calls out, getting everyone to look back while he points towards Eagle-Nine as it comes flying over towards them.

"Finally…" The sergeant said, soon looking back to Randall as he moves back and was about to move back towards his car "Where do you think you're going?" The sergeant asks, getting Randall to stop while the sergeant raise his weapon towards him.

Doom steps forward and grabs the sergeants gun, grabbing the front of it and lowering it down before he stood in front of him, seeing him shaking his head while Lauren had her hand on her handgun, about to draw but Doom looks to her, causing her to stay where she is.

"Let go!" Sergeant said when moving back with his weapon

"Do yourself a favour sergeant." Randall calls out to him "He's on your side; try not to piss him off." He looks back to Doom "You take care of yourself; I hope we see each other again." He turns back and walks towards his car, hoping that it still works after hitting against the wall with an Archon.

"Sir…" Lauren steps forward

The sergeant sighs and backs away, looking up at the Blackhawk as it tries to land down onto the ground. He calls his men to get a move on, picking up the precious cargo and sending it onto the Blackhawk before they all get on.

Everyone would jump on board but when Doom was about to the sergeant raise his arm to his chest "I don't know who you are, nor do I trust you. I am in charge here, so don't get in our way or you will regret it." He lets go of him and gets on board

Doom finally gets on board the Blackhawk, switching back to his machinegun and sitting next to Lauren. "My name is Corporal Lauren." Lauren said "Welcome to Rhino Squad."

"Alright let's get a move on." The sergeant said, soon taking off his helmet when the Blackhawk begins to take flight, showing his face as he appears in his forties, appearing in dark skin and has short dark hair, showing a couple of scars on his face.

"I hope you're ready of what is to come, Doom marine." The sergeant said "Because your about to walk into enemy lines."
