Doom got away with beating up the marines who held him in a prison and did not seem to want to be stuck in another prison for another long time. This here he got away with it, now he must join the UAC to help combat the demons. Doom is under watch for the time being, seeing that Rhino Squad found him; they are the ones to see how capable he is when they send him to the armoury.

One of the marines of Rhino Squad came in to instruct him to see how good he is in combat, he and four more marines came in the room without their armour, only wearing the black tights that they wore underneath the armour. Doom was standing near a table full of guns, seeing new and improved guns, after all, it has been ten years since Doom came and the UAC now has new weapons to use against the demons.

"It's good to see you're out of prison." The marine said when walking over to him, carrying this large box in his right hand then lowers it down and lends his hand out to shake Dooms hand "My name is Corporal Rhodes, Rhino Squad, pleasure to meet you in person."

Rhodes gets a handshake form Doom, seeing that he gave him a strong and firmed handshake, causing Rhodes to back away and shaking his hand back when he lets go. "That's a strong handshake." Rhodes said to him "Well anyways…" He turns his head towards the table full of guns "See anything you like?"

Doom got a look at the weapons before picking one of them up, he did stop and grabs a regular weapon, a G36 modified light machinegun. The gun shows a covered case, making it more affective against the demons and is the UAC's main weapon in combat.

"Ah so you found the regular looking design, the weapon is slightly better than the previous FN-Minimi machinegun but might shoot better. The gun shares the same piercing rounds like the machinegun you once used, you should try it out."

Doom took aim at the targets in front of him, seeing cardboard demons appearing and getting him to start firing rounds through them. He aims the machinegun at their heads first, sending their heads falling back then aims to the chest, shooting through three demons and wastes only twenty-four rounds.

"You're good when it comes to killing demons… Wait till you try this one." Rhodes takes out the grenade launcher and shows it to him when Doom looks back at him. "This here is the grenade launcher. This gun exceeds the Milkor Grenade Launcher."

Doom leaves the machinegun on the counter in front of him and grabs a hold of the grenade launcher, examining it for the moment. The weapon looks like a combat shotgun but has the ammo case of the grenade launcher that Rhodes mentioned, seeing this dark greenish grenade launcher that could hold up to eight grenades. Once Doom examined it he turns back and aims it towards the closest demon cardboard, he fired through, blasting the target to bits.

Corporal Rhodes simply laughs right after he blew up that demon "Okay… I think we can try one more weapon, the colonel wants to see you after training and we can't keep him waiting." He turns back once more and grabs a modified Chaingun off the table and lends it to Doom when he came back to the counter to place the grenade launcher next to the machinegun.

"This here is a way modified Chaingun with a good kick to blow the demons away. It holds up to four hundred uranium-piercing rounds; this can tear a Baron to bits. I know you will love this one."

Doom came up to him and looks at the Chaingun, seeing it looks smaller than the previous Chaingun he used. He picks it up, examines it, seeing it is lighter and has a handgrip on the left side of the gun and a handle at the back end of it. He would turn back to test this gun out, only to stop when Sergeant Travis came into the room, interrupting the training.

"Corporal Rhodes."

"Sergeant Travis."

"How is your new friend?" Travis looks to him as he looks back to him, holding the gun with one hand and having the front of the Chaingun aiming at the floor.

"Oh he's experience when it comes to guns." Rhodes said "He's about to test out the new and improved Chaingun."

"Sorry but he can't do that right now." Travis walks up to Doom "Colonel Logan wishes to see you right now."

"Sir?"

"Sorry Rhodes, you have to play with your weapons alone for now." He looks back to Doom then looks down at his gun "Maybe you should leave it here, it's better to waste the ammo on the demons and not us."

Doom turns back and places the Chaingun next to the other two guns he used. Travis would turn back and walks out of the room while Doom follows, having Rhodes to stay behind and pack up the weapons as he didn't want to do some shooting at this time.

"That kid is strong; he's good when it comes to weaponry and upgrades." He said while he keeps walking "Rhodes also wanted to modify that double barrel that you love so much. If you like he would actually make it stronger than before." Travis looks at Doom when he notices him looking back at him "I have your double barrel, I just thought that maybe if you allow Rhodes to modify it then you might enjoy shooting that gun without reloading it. Rhodes mention that he could merge the regular shotgun with the double barrel, that way it shoots like a shotgun but has two barrels instead of one and will surely make a big kick out of the demons."

Once they reach the communications room, Travis and the others notice that nearly every higher-ranking officer was standing here in this room, almost forty of them are superior and have control over the rest of the grunts. All of them came here to see the colonel but was not here at this time, he needed to wait for Doom to arrive. The moment Doom came into the room, some people looks back and notices him here, causing the gossip and the whispers to begin as they heard the rumour about this man being the bringer of death to the demons.

"Oh man, I didn't know rumours reached this far throughout the base so quickly." Travis sighs then looks to Doom "It looks like everyone is going to love you now. Doom Slayer."

"Listen up everyone!" Colonel Logan finally arrives in the scene, causing everyone to stop the talking and turn heads at the front as he comes in and stands in front of the screen looking at everyone with his hands at the back of his waist. "We are back in a 'Code: Red' situation. The demons have begun massing an army, capable of overrunning this entire base which they will try to do in four hours."

Everyone began whispering to one another when he mentioned about the demons attacking the base, Logan soon stops this by stepping forward and continue to speak. "I have already made contact with other UAC facilities but they will not send reinforcements, I also ask for some aerial assault or some ships but it is a no go on our side. We will have to rely on everything we have, we cannot afford to leave anything in reserve against this demon force, that is why I want everyone to be at the ready when they show up." Logan would turn his back to them and looks back at the screen "VEGA."

VEGA turns on the screen and shows the map of the whole base and the whole surrounding areas, showing many blue dots placed throughout the base, indicating they are the marines. Once all the blue dots are covering the base, the red dots will appear far away on the edge of the screen, showing the demons have begun massing their forces to attack the front gate.

"Now the demons will try to storm the front gate, which is why I want the walls to be occupied by marines in one formation. The rest of the marines will stay in the trenches or further back, they will be our covering fire if the wall is breach, which will give our men on the walls and inside the bunker the time for them to retreat. We will use Eagle-Nine as our aerial attack in the sky and our plasma cannons as our artillery batteries, they will shorten out the demons once they get too close to the walls."

"I'm not going to lie to you guys but we will be facing strong odds in this time of need, we are on our own and we have to do anything in order to win. If the demons defeat us then they have a chance to attack the city, we cannot allow the demons to succeed, I need all of you ready and prepare for battle. Anyone here have any objections?"

Nobody responds or objects to anything he said, some did spoke to one another but they never step forward or say anything to Logan. After that, Logan orders them all to get ready, got them all to rise up off their seats, and prepare to move outside while Doom stands where he was with Travis.

"Sergeant Travis and the Doom Slayer." Logan calls out to them "A word."

"Oh I knew this was going to happen…" Travis said and looks to Doom, seeing him walking through the crowd with Travis following him from behind.

Logan turns back to the screen "VEGA."

"Yes sir." VEGA changes the screen and uploads nearly every information, image, codex and anything else from the Mars incident, placing them over the screen for the three to get a look at it.

"I was checking through some of the databanks of the codex of the Doom Slayer." Logan said when looking at the screen. "VEGA told me everything on what happen on Mars. Olivia Pierce, Samuel Hayden, the UAC, the demons and now you." He looks back to him "The Doom Slayer."

"What…. I thought Samuel Hayden said that the whole Mars incident by a failure of containing the Argent Power." Travis said "Olivia Pierce was the one responsible for all of it."

"I just knew that there was some cliché about the whole Mars incident and the whole Hell on Earth. Both of them are the same, VEGA told me the truth and after all…" He looks back to VEGA "You can't really lie.'

"Of course I can't." VEGA said "Samuel Hayden awoken the Doom Slayer to contain the demon threat on Mars. He succeeded and defeated Olivia Pierce and in the end, Samuel Hayden wanted to continue the work on Argent Energy, in the end it appears that he failed to contain the demon threat."

"I don't know if Argent Energy was the right choice but in the end we did need that power source to survive but we didn't expect to deal with another demon invasion from what happen on Mars."

"But if you knew about this and so did everyone else in the UAC, why is Samuel Hayden still commanding chief of the UAC?"

"Samuel Hayden covered as much of it as he can and worried about continue the work of Argent Energy. When the apocalypse began, no one didn't really care about what happen up there so they forgotten all about it and worry about what's in front of us." He looks to Doom "If you want Samuel Hayden… You need us; if you want us to help you then we need you to destroy the demons that attack Firebase Bravo."

Doom nods to Logan and would turn back after that, taking his leave from the room while both of them watch. Logan looks to Travis before he too takes his leave. "Make sure he doesn't go over the top when he's out there."

"Will do sir." Travis salutes to him before he too takes his leave from the room.

"If there is a god out there, I hope this man is the bringer of death to the forces of Hell."

Firebase Bravo now been put into full lockdown after the discovery of an army of demons are on the move, this here is when they will try again before the UAC make their move to strike back against the demons. This here will take place in the darkness where four hundred UAC marines are all stock with guns and ammo, armed with everything they can use, getting themselves in positon before the enemy come.

The demons will prepare their attack by attacking the front of it; no point attacking from all sides, storming the front door is the key to get themselves inside, there they can begin the brutal carnage to get rid of the UAC. This here will get everyone in alert; all four hundred men will be place on the walls and in bunkers while the rest stays back, here to play as reserves just in case something happens. The Blackhawk will be their aerial cover, assisting the marines from in the air once its fuelled up and ready let loose.

Lauren was station onto the watchtower while Rhino Squad, including the Doom Slayer himself was on the wall with the others, seeing that he is taller than the other marines are but they did not seem to care about that right now, some were curious but they kept their heads facing the front. Lauren was lying up there with the other marines on the tower, all next to one another, having their magazines placed next to them so they could reload quickly.

"Are you boys ready to kill these sons of bitches!?" One of the marine said when walking past the marines who stood in a line at the top of the wall "Show them no mercy, don't stop shooting until there all dead!" He kept walking past them from behind and moving towards the location where the bunker is, moving to the top where there is a mounted plasma machinegun is located. The plasma gun is a modified 50-Calibur, instead of shooting regular bullets, the gun now shoot long plasma rounds and the speed velocity is higher than a regular bullet could fire from a 50-Calibur.

Doom looks back to him then looks out at the view, seeing Sergeant Travis and Rhino Squad stood next to him, all armed with the same weapon, the same weapon that he used before that was a modified version of the G36.

"You're the bringer of death to these demons right?" Travis asks him before he puts on his helmet "Show me and everyone here that you mean business." He looks forward and takes aim over the wall, looking out at the hills in the far distance.

Colonel Logan was inside the watchtower to get a good look over the area, using a computer to get a look out in the open as he has control of the camera of a drone that was right up in the sky. It was circling around this whole area, showing him the targets before his men see them. Logan waited for a little while before something comes up, soon seeing white signatures on this green screen of the area, seeing thousands of demons approaching this area.

"Holy shit…" He mumbled to himself, slowly looking up "There coming…"

Doom is about to see things that is soon going to get harder because he is going to face something that he has not face in a very long time, things are about to change bad when he sees not just the armies of demons that he has faced on Mars and in Hell. An army will come over that hill, revealing themselves to the UAC, seeing that they are not an army of Imps or Hell Knights or Barons, they are humans who are demons. An army of humanoid demons, all wearing armour made of bones, covering many parts of their body, all having this dark red, grey or bluish colour on their armour, also seeing that they have purple skin underneath that armour. All of these humanoid demons are different form one another, all having different types of armour and different helmets but all look the same. All of them wield advance weaponry, possessing Argent weaponry that shoots orange energy blasters, these projectiles fire like regular laser beams.

Doom lowered his weapon when he got a look at the humanoid demons, causing Travis to look at him for the moment when just realise he lowered his weapon. "What's the matter?" Travis said to him, he then looks back at the demons then to Doom, trying to see his face through the visor "I can't see you well… But you look like you seen a ghost."

A flashback would happen he saw a flash from the past, seeing that it has been a very long time since he saw those types of demons before. This took place before the events of Mars, before the UAC, this took place during the beginning, during the time when he was alone, fighting alone against a new enemy he discovered when coming through a rift he found. He stood alone against this enemy of demons, seeing the humanoid demons he sees today, instead of darker colours they wear today; they all have the colour of white.

Doom was standing on the high ground with his Chaingun, shooting down at almost thirty demon warriors that was approaching him, seeing they all wield rusty but sharp looking swords. They try approaching him while he continues spinning out bullets from the Chaingun, he only took a couple of cuts from them but he continues shooting. He already took down several of these demons until finally, his Chaingun stopped spinning.

Doom notices his gun ran out of ammo, after that the demons began advancing towards him, causing him to throw the Chaingun at the one in front of him and starts moving backwards. Doom backs away and switches to his ultimate weapon, the BFG9K. He let loose a green energy ball out of it, firing it towards the demons, sending the green energy ball to explode and incinerate every demon in the area. He obliterated them to bits, leaving chunks of their parts on the ground while Doom stood there, breathing a bit heavily and soon lowered his gun. Once there is no more demons around, he moves forward, walking over the corpses of what is left of them.

Doom suddenly stopped when he walks over the bodies, he heard a noise coming from the doorway on his right, causing him to take aim towards the door and waits for the moment before moving forward. He proceeds with caution, not knowing what is behind those corners but when he goes past the door, going to the left corner, staying to the side of the wall and getting a look towards someone who was not a demon. There was a human right here in a place like this, a female who had her back towards Doom, she was crouching down and examine the four bodies of these demon warriors that Doom killed earlier. She wore the silver and greyish armour, a feminine version of the Praetor Suit, the same woman that Doom saw when he was stuck in the dark depths of hell.

She soon sense the feeling that she is not alone here, causing her to quickly spin while taking out her advanced weaponry that looks like a rifle. She took aim towards the Doom Slayer as he aims back at her, causing her to be shock to see a non-demon standing right here in front of her, seeing that he is not one of them but she was still shock. She lowered her weapon while standing back up, the same goes to Doom as she does not look like a threat.

"Hey!" Travis punches his arm, causing Doom to wake up from that flashback, causing him to move back before looking back to him. "We can't have you losing your mind now."

"Hey what's that guy in the middle?" One of the marine said to Travis, getting them to look back out there.

The demons in the middle moves to the side to allow someone to go walking through to stand at the front of the army, seeing this figure who stood taller than these demons. This demon appears to be a type of cultist or an acolyte, seeing he wore these ragged dark robes, carrying a long staff and has this weird looking face. His head was this rectangular looking thing, seeing he has no eyes but has three mouths, one at the front while the two are on the left and right.

"I think it's a Cultist." Travis said to the marine "These guys are worse than Summoners."

"Worse?!"

This strange demon looking cultist would begin to say a few words, speaking in a strange language, saying these weird things until suddenly a gunshot went off. A sniper fired while it was talking, sending that bullet straight through the head and blowing the head off, causing everything to be silent as they soon to find out that it was Lauren who fired that shot. She fired through that demons head and blasting it to bits, sending that demon to collapse onto the floor while the demons around the Cultist looks down at it for the moment, soon looking forward and seeing that there is no one controlling them.

"What the hell are you doing?" Colonel Logan shouts out to Lauren, standing behind her "I didn't order you to fire!"

The demons held their ground for the moment as the Cultist collapses onto the ground, soon seeing they are becoming restless, seeing they want to do battle right now, that is what they are about to do. They look forward and move and the demons at the front and second row behind them began to open fire at the men on the walls.

"It begins…" Colonel Logan said, looking out at the view as they are coming.

The marines on the wall ducks down to avoid the shots they fired, they soon came back up and started shooting back at them, unleashing thousands of bullets in a second, firing off so many rounds over the field, piercing through the demons and sending the front row demons to collapse onto the ground. The snipers and the men inside the bunkers let loose their bullets as well, the men in their bunkers fired these plasma rounds at the demons, seeing the projectiles shoots just as the demons do.

After a minute of taking all of those hits, the demons would shoot back, firing back these orange energy rounds across the field, hitting the marines on the wall and hitting the wall as well while they keep charging. The demons continues firing at the men on the walls, sending them falling off the walls and crashing hard onto the ground.

Doom and everyone else on the walls kept firing down at them, he took two hits to the chest but he kept firing his weapon, soon to run out of ammo but one of the marines next to him took a hit, getting the chance to ditch his gun and take his before he falls off the wall. Sergeant Travis was still by his side, still shooting down at the demons until he crouches down, taking a hit in the shoulder and was so close of falling but was still alive and well. Travis got a look at the bodies that fell from the wall, seeing many marines dead in an instant; this here got him up out of cover and continued firing.

Colonel Logan would contact the men on the ground through the radio in the tower, contacting the man near the artillery cannons. "All cannons, fire now!"

The four large artillery plasma cannons took their aim in the sky, firing off this huge plasma ball into the sky, flying over the wall and soon crashes down on the demons. The plasma artillery cannons at the back fired further, seeing that they have control of how far they can fire. Four of these plasma cannons made their marks on the land, obliterating a large handful of demons and changing the tide of war in their favour, killing more demons but they continue attacking, the demons continue charging even though they are losing more but they still had more numbers.

On the hill where the demons was first spotted, another Cultist came forth to replace the one who got its head blown off, here to take care of the situation as they are losing right now. This here is when this Cultist plans to turn things up a notch. The Cultist looks back as it brought two friends to help the fight, bringing two Guardians that looks just like the Pinky demon that Doom fought in the dead city. The Guardians appear more armoured than before, if possible, these two are a battering ram.

Colonel Logan got the look on the hill when seeing the Guardians and still many demons charging towards the wall, seeing the Guardians begin moving towards the wall and slowly getting faster by the second.

Logan would lower his binoculars; he then looks to Lauren and the snipers, giving them a new order. "Snipers! Take out the Guardians, now!"

Lauren fired her shot first, seeing it hit the top of the armoured skin but the Guardian kept moving. The other two snipers fired one at the head and the other through the leg but it was not slowing down. Lauren and the other sniper both fired at the same time, hitting the head and causing the Guardian to collapse. It was now up to the men on the wall to shoot down the other Guardian, seeing that their weapons are not doing well; they were force to abandon the wall.

Doom switches to the grenade launcher and started firing at the Guardian while everyone else kept firing at the Guardian and the demons, Doom fired two times to the face before finally the Guardian hits hard against the wall, hitting underneath where Doom is and causing a serious shake. The Guardian got itself killed after it made a huge dent against the wall, it made a huge crack and cause half of the wall to collapse but it held on for a while. The demons would try to target the broken wall with heavy weaponry, armed with heavy cannons that they place on their shoulders. The demons take aim to fire, only to stop when the snipers took aim and fired through their weak points, killing them instantly.

Doom continues firing a couple of grenades across the wall and taking out some of the demons but was not enough, he decided to move across the wall and take the mounted plasma gun that was un-operational, seeing the one who was using it before took two shots to the chest and one through the head of his visor. Doom moves him to the side and grabs the handle of the gun, aiming it around and firing plasma rounds through the demons, piercing through their armour and killing them quickly. The demons would take aim towards him, hitting his armour but their shots are not making much damage to him as he continues shooting.

The fight continues going on the walls as the demons continue trying to damage the broken wall, which would surely collapse so they could break through but no sign of any breach yet. Many dead marines are lying on the ground behind the wall, seeing they are just lying there while everyone else kept fighting until a certain change occurs when Colonel Logan gets a look across the field. Logan uses his binoculars to check around the area, still seeing the demons moving forward over the hill and seeing that Cultist is still alive, it looks like the Cultist has its side turn towards the base while it looks out to somewhere else.

"What the hell is it doing?" Logan mumbled to himself then looks out of the view of where the Cultist is looking, getting a look across the hill in the east, there he got a lock on enemy demons on the high ground. "Oh my god…."

An Archon of Hell stands on the cliffs, looking out at the base and lets off a roar while Cacodemons, Lost Souls, Revenants, Imps and also a new unique demon that has joined the flyers. It was a unique demon that Doom saw before, it was a tall and muscular looking demon that looks like a Hell Knight, having curved horns on where eyes are meant to be and very sharp teeth, its arms are long that reaches to the knees and has wide wings on its back. There was a handful of these creatures, flying across the air and going straight towards the base from above.

"Eagle-Nine." Logan turns towards the front of the base, seeing the UAC marines on the ground just spotted them and began firing. "We need your air support on the right side of the base."

"Roger that… Taking flight now." The said when turning on the Blackhawk and try to get up in the sky and began moving behind the watchtower just to avoid sniper fire or friendly fire from the ground. "Alright, spin it up."

The Chaingunner on the side of the Blackhawk takes aim and begins spinning up and fire, firing through the demon flyers and taking out a handful of them, seeing the flying demons are trying to avoid weapons by flying around to avoid the shots. The demons continue flying closer to the base, having the marines on the ground firing at the demons while Doom and other marines stayed on the wall and continue firing.
