Prologue
On board a UNSC paris class frigate fireteam crimson were being briefed on the mission they were being sent to. "When planet side you will head to the way point and retrieve the artifact while we distract the covenant above the planet" the captain said the majority of crimson headed to the armory except for the David the team's leader. "Sir what if we fail to complete the mission" David asked "if you fail to complete the mission in time we will be forced to destroy the artifact and the AI with mac rounds understood" the captain said "I understand sir" David said as he joined his team in the armory. Pulling his assault out of the weapon rack Nate the team's combat specialist put his weapon on his back and a magnum at his side. "Really the assault rifle again why don't you pick something else for a change" Jack the team's demolition expert said as he put his spartan laser and his railgun on his back.
"I like the SMG but the assault rifle has an ammo counter besides I'm not the one with a smart AI" Nate said "hey it's not my fault Ali and I make a great team" Jack said as Nate's sister Maria the team's sniper picked up a sniper rifle and SMG. Putting his plasma pistol on his side Edward the team's medic and tech specialist pulled a SMG out of one of the weapon racks. Putting her saw and rocket launcher on her back Cross picked up a large chain gun and loaded it with a fresh drum magazine "a bit of overkill isn't it" Scarlet the team's CQC expert said as she equipped her shotgun and gravity hammer as Cross just gave her the death glare. Equipping his battle rifle and putting his magnum to his side David grabbed his helmet and put it on as the rest of the team did the same and exited the armory to the pelican.
On the ride down the team were preparing for the fight ahead and were preparing themselves "whoever get's the least kills has to buy drinks" Scarlet said "sounds good to me" Nate said. As the back doors opened they saw Promethean soldiers and crawlers attacking nearby marines. Firing her chain gun Cross embedded multiple bullets inside of the crawlers and soldiers. As the spartans jumped out of the pelican it dropped of the warthog it was carrying and Nate drove the mongoose out. "Cross, Jack stay here and guard the pelican, Nate will drive the mongoose and Ed will ride with him, Maria will drive the warthog Scar you ride shotgun I'll operate the turret." David said as everyone did as he said. As fireteam crimson drove towards the objective they saw banshees shooting at phaetons and vise versa. Driving down the hill they saw a phantom lower down to drop troops off "Ed take out that phantom" David said as he jumped off the mongoose and used his thrusters to boost himself up into the phantom.
Firing his SMG and killing the six grunts in the ship Edward pulled out his plasma pistol and overcharged it disabling one of the elites shields and killed it with his SMG. As he pulled out a plasma grenade to throw into the cockpit an elite zealot tried to hit him with it's energy sword making him drop his SMG out of the ship. Kicking the elite in the gut Edward picked up a nearby carbine and threw the plasma grenade into the cockpit. Jumping out of the phantom Edward landed on the back on the mongoose as the grenade went off causing the phantom to crash. Arriving at the objective fireteam crimson exited their vehicles and entered the forerunner structure. Walking through the halls of the structure the spartans encountered no resistance and noticed that none of the forerunner defences were offline.
"Shouldn't this places defenses be online" Edward asked "maybe there are no inside defenses" Scarlet said as they entered the main room they saw the artifact "well that was quick" Scarlet said as she began to walk forward before being stopped by Maria "guys my tracker just lit up" Maria said as everyone raised their weapons "active camouflage!" David said as fourteen elite zealots and one elite general appeared and activated their energy swords except for the general. "You think that's the leader" Nate asked "no shit" Scarlet said as the elites charged at them. Firing her shotgun Scarlet killed one of the elites as another swung their swords making her duck and pull out her knife. Stabbing the elite in the eye Scarlet pulled out her gravity hammer and hit one of the elites in the stomach with the blade and sending another flying off the ledge.
Firing his assault rifle David killed an elites and stabbed another with his knife. Ducking underneath one of the elite's blades David punched it in the gun and kicked it off the ledge. Firing his carbine at the elites Edward was able to kill two before almost being stabbed. Overcharging his plasma pistol Edward fired the weapon into the elites head before killing it with a couple more plasma shots. Shooting her SMG at one of the elites Maria was able to kill it before it was able to reach her. Dodging one of the elite's blades Maria quickly kicked it and then stabbed it in the head.
Pulling out one of his knifes Nate quickly stabbed one of the elites in the neck before charging the general. Pulling out it's energy sword the general activated it revealing a dark red blade. Swinging its sword Nate slid underneath the blade. Firing an entire magnum clip at the elite Nate's pistol finally clicked as the general kicked him of the ledge. Grabbing the ledge Nate held on for dear life as he saw his magnum fall to the bottom before looking up and saw the general raising his energy sword. "Die demon" the general said as a sniper round went through the general's head. Falling to the bottom the general finally hit the ground as Nate looked up and saw Maria holding her hand out to help him up.
Grabbing Maria's hand Nate was pulled up by his younger sister Nate dusted himself off before thanking Maria "thanks sis that's twice you saved my ass" Nate said "not a problem" Maria said as Nate picked up an energy sword. "Let's grab the artifact and get out of here" David said as Edward grabbed the artifact and the team headed outside. Placing the artifact into the back of the warthog David heard gunfire over the comms "sir the lZ's hot right now did you get the artifact yet" Cross said over the comms "we need emediate assistance" Alison the teams AI said over the comms. Yes we got the artifact and are on our way back" David said as the teams got back on their vehicles.
Firing the turret at the ghosts that started chasing them David was able to take one out as Edward disabled the other one with his plasma pistol making it fly off the side of the cliff. Driving towards the checkpoint they felt the ground shift as they saw the ship they were on explode "crap what are we gonna do now" Nate asked "we need to get to the star of eternity and get the hell out of here" Edward said as they saw the pelican being under fire. Cross was mainly dealing with the elites while Jack was mainly using a assault rifle to kill his targets.
Running over three grunts with the mongoose Edward and Nate jumped off the mongoose and started to fire their weapons at the covenant. Driving over a ramp the warthog landed on four grunts and one elite as Maria and Scarlet jumped out and David stayed on the turret. Grabbing one of the grunts needlers Nate shoved it into the grunts head and kicked it too another group of grunts before the needler blew up. As the fireteam held off the the covenant forces another phantom came in and dropped off an elite ultra and two hunters "hunters!" David said as they rolled out of the way of one of the hunters beems.
Charging towards the hunters Nate was hit by one of their shields and was sent through a garage door. Sliding between the hunters legs Jack pulled out a frag grenade and shoved it into the hunters back before jumping away from it and letting the grenade kill it. Recovering from the blow Nate looked up and saw an old cyclops without any weapons or tools 'hello beautiful' Nate thought as he climbed into the cockpit. Activating the cyclops it's inside heads up display came to life as it stood up. Walking towards the door Nate used the cyclops' strength to break the door open catching the attention of the hunter. Slamming his fists together Nate ran towards the hunter as it charged it's cannon.
Grabbing the hunters shield Nate punched the hunter so hard that it's body went flying off the shield. Throwing the shield to the side Nate stomped on the hunters head before he walked towards the hunter that fired it's cannon at Nate causing the cyclops' right arm to be torn off. Ignoring the damage Nate ran towards the hunter and stomped it's head in before punching it's back killing it. Exiting the cyclops Nate saw the rest of his team dealing with the elite ultra. Ducking underneath the blade Cross punched the elite in the gut before being sliced in the chest by the elite's energy sword severely injuring her.
Jumping on top of the elite Scarlet pulled out her knife and stabbed the ultra in the neck killing it. Helping Cross onto her feet Edward carried Cross over to the pelican as the rest of crimson entered the pelican with the artifact and the vehicles. As the pilot took off the pelican ascended the artifact began to glow orange and opened a slip space portal behind the pelican. As the pelican shook Nate fell out of the pelican and into the portal before being joined by the pelican.
A/N: Hey guys I hope you enjoyed this chapter and here is a preview on what's to come.
"Is that a robot" Nate heard as he opened his eyes and saw four girls standing over him.
