The Human Covenant War rages all over Reach as the humans are trying their best to hold them off but the covenant is in the lead at the moment. The marines along with the three Spartans called Shadow Team are battling against a force that wants to take over the region all they need to do is remove the UNSC in this area.
"Come on lets go lets go let's go!" Adam shouts at the others as he fires a grenade launcher at the elites, taking out three of them
"We have to advance, take out that gun now Joseph!" Mark said to Joseph on the radio in his helmet
"I already got it covered..." Joseph was shooting the infantry inside the gun then walks over towards it and throws a grenade inside the core before running out of there throwing another grenade towards an elite but he evades it.
The large AA gun would explode, taking out a few infantry that was nearby and makes Joseph return to the others as they advance forward thanks to the Scorpion tank they have, it takes out the Wraith tank and pushes forward to finish the rest of this off.
"We have to move. Go!" Mark said and grabs the grenade launcher Adam was about to fire, he fires in the air disabling the ghost that was coming then watches the tank blow it up.
A few marines were killed but they continue going forward until there all dead, finally the battle was over they return back to the place they fought before as there was no other path to take them further. They return to recover their wounds and repair the tank, the three Spartans returns together elsewhere to plan their next move.
"The covenant is not on this side of Reach... maybe we should pull back and head to Sword Base." Joseph said to Mark
"If we move to Sword Base we could maybe help them defeat the Covenant there, i heard they are planning another attack on that base, we should help them." Adam said
Mark looks over seeing the sergeant walking over to him "Sir me and my men are ready to move out, we will now obey in your commands."
Mark looks to the other Spartans then back to him "Then we guess we go to Sword Base."
It started to get night when they made it to this base but it was already under siege by the covenant, they got themselves a Scarab walking around outside the base while the infantry was pushing forward, they were fighting inside the base as they cannot defeat them without help and they can't call for air assistance because they are busy taking out that Scarab and the banshees nearby.
The group led by Mark makes their way towards the Scarab before heading to the base; all they have to do is hold the covenant until they arrive. The Scorpion tank drives full blast towards the scarab and starts firing at its legs while the rest of the marines surround it and target he infantry on the Scarab, Joseph would try to get to high ground and jump on the Scarab but fails, Adam ran out of his grenades and notices a twin 50cal machinegun stationed near the front gate of the area, he would run towards it and moves the dead marine out of the way and aims it in the air as Banshees were coming down to take out the tank, he shoot burst fires at the Banshees but once they were destroyed he just pulled the trigger down hard firing rapidly at the scarab taking out the head of the it but once it ran out of ammo he quickly got out of there before the front of the scarab shoots its cannon towards it, destroying it and the front gate.
The Scarab finally exploded when Mark charges through inside and took out the core once it lowered thanks to the tank, once that was done they quickly run through the gate but had to ditch the tank, they run through fighting the covenant along the way but they get stopped again as two hunters stands before them, they do hear fighting inside the base so they need to get there quickly.
Mark and the others scatter all around the area but then he spots a red Railgun on the ground near a dead Spartan, he quickly runs towards it and picks it up then fires towards the Hunter, it only has three shots inside but he fired three bluish beams towards one of them, the third hit killed the hunter and then notices Joseph jumping at the back of the hunter and fires a few times at the head with his rifle, finally it died and then falls to the ground.
"We have to save the marines... go!" Mark said to the others before throwing the Railgun away then runs through inside the base to attack the covenant inside.
The marines charges through but they all reload before running inside, they notice a few marines left and they help them out before by ambushing the infantry from behind, they all open fire down at the covenant taking them all out one by one until there is nothing left of them. Mark jumps down from the area to see the survivors personally.
"You all alright?" he takes off his helmet
"We are what's left of Sword Base, they killed all of us, attacked us while the rest of us went to war against the covenant."
"Then there is nothing left for us to be here." He looks back to the others "Get as much ammo as you can, were getting out of here, and were going to join the front lines."
"Yes sir." Adam turns back and returns to the others to tell them the situation
"Were getting out of here... we're going to join the others on the fight for Reach."
They all prepare to head out of there by calling in some support on getting them all out of there. A pelican arrives to pick them all up and also picks up the tank also as they might need it for later, the pelicans starts to fly out of Sword Base and move to the place where the Pillar of Autumn lies that they will go and protect it against the covenant army.
The Pelican took an hour to make it to that destination and once they landed they made it down there safe along with the tank as well, they quickly prepare to attack the covenant as they were already there trying to take the bone yard.
"Joseph i need you on higher ground, take them out as you go." Mark said to Joseph as he keeps shooting with the M41A Pulse Rifle
"I got it." He runs past him firing a few rounds them heads to this large building, he jumps on top of it and starts shooting down the covenant by doing a few headshots.
Adam decided to take the tank by targeting the strong ones like the brutes and the elites along with their vehicles just so they can press forward. Victory will soon come to their side but suddenly they can hear a Scarab coming towards them from behind, it comes out of nowhere as it climbed up the mountain to get to that area. The moment the marines spots the Scarab they quickly scatter around the place but once they were all looking at the Scarab another appears near Joseph, it was on a cliff looking down at him, he would slowly looks up seeing it and didn't have a chance to escape the Scarab cannon, it would obliterate Joseph and that building he was on.
"Joseph!" Mark yelled out as the Scarab blows up that building, he then looks back seeing the other one moving close to him.
Adam would start firing the Scorpion at the Scarab to make it go against him, a grunt on the Scarab would charge a plasma pistol and shoots the tank making it disable for now but Adam would have to jump off of the tank before that Scarab destroys it along with him.
Adam escapes the blast but his shield went off when he ran to Mark, they would all flee the area as they do not have the fire power to take out those two Scarabs so they retreat further in the boneyard and in the buildings along with the other marines before the Scarabs starts coming over. They take a break and Mark was furious about the death of Joseph in battle but they would have to keep going and make it to the Pillar of Autumn before it takes off.
Mark and Adam are ready to move, with their weapons out of ammo they switch to their secondary fire and that's the P33 Pereira Semi-Automatic Revolver with 8 rounds and has mounted a laser pointer underneath the barrel of the gun. The two takes point while the others stays behind them as they move further in the building, they do make it outside but notice a few covenant infantry around so they scatter around the area and shoots down the Brutes with their revolvers, those guns were strong like a sniper rifle, it took them out two or three shots, if they were close enough they would maybe kill them with one shot of their gun.
They notice a Wraith nearby and they don't have the power to take it out so they need to hijack it before it comes close to them but suddenly a cannon fire went off, blasting the Wraith with one shot to the side, it was a M777 Howitzer artillery that was stationed on the side of the cliff, it was in the tanks range so they took it out with one shot to save the Spartans on the ground.
"Glad we got someone on our side." Adam said as he reloads his revolver.
"Let's keep moving... let's go!" Mark shouts to the others then moves through to another building, heading to the Pillar of Autumn
The battle for the ship has already started, they already notice two Spartans on the field fighting against the covenant, one was controlling the large gun that can take out a few of their drop ships, with the reinforcements they manage to defeat them for now but it won't be long before they return again.
They notice a few help arrived in the air, two AV-22 Sparrow hawks appear and helps them out but one of them lands on the area as one of their pilots were shot in the air and needs someone to replace him. Mark decides to take the Sparrowhawk while Adam stays on the ground and helps the black Spartan fight the covenant, they did notice a Pelican coming down on the area and the black Spartan would head over to the landing pad to deliver something to them.
During that delivery another Phantom appears near the gun just when a covenant cruiser was in route to this position, preparing to charge it's ion cannon, the elite zealots took out the Spartan using the gun and no one can stop the cruiser coming over so the black Spartan and Adam joins together while the rest of the marines jumps in the Pelican, Mark also stays here while the other hawk defends the Pelican while it returns to the ship, Mark has the sky and it's up to Adam and this Spartan to clear out the zealots and take out that ship.
It took them a while before they can take control of the cannon, Mar was still in the sky fighting some banshees but then he notice two Seraphs coming towards him, the Spartan controls the gun and targets the phantoms coming their way while Adam secures the area. During the skirmish in the air one of the Seraphs manage to damage the Sparrowhawk's engine, causing it to crash landing but not on the fields it would crash land down the hill.
"Adam... good luck out there... i will see you in the air... over and out!" Mark said his last words before the Sparrowhawk crashes down on the fields, Adam looks back at the black Spartan as he continues shooting at the phantoms.
The cruiser was just in the range and the Spartan open fires; it targets the main gun causing that ship to sustain heavy damage to that blast, inside the blast it took out a few areas before it would fall from the sky and crash on the ground close to where Mark crashed. Adam and the Spartan watches the Pillar of Autumn takes it's leave by preparing to fly in the air once they have the precious cargo, it takes flight and heads out of there while the Spartans stays on Reach and prepares to do a Lone Wolf mission, their final hour against the rest of the covenant that are still on the planet.
