Metal Gear Effect

Disclaimer: I do not own the MGS series or Mass Effect. They belong to Konami and Bioware respectfully.

Summary: Humanity continues to advance without the Patriots control. Nano Railhine enhance and regulate without blocking off our emotions, cybernetics are advancing at an astonishing rate, and eventually humanity becomes a spacefaring species.

(A/N: Basically Metal Gear Solid tech, specifically Metal Gear Solid 4: Guns of the Patriots and Metal Gear Rising: Revengence, in the Mass Effect universe. While there are a few ME/MGS x-overs none of the do what I'm gonna do.)

Chapter 1: Timeline and First Contact

2014: The Patriot System is taken down, and humanity moves forward on its own.

2020: Surprising everyone David Hayter, more commonly known as Solid Snake and Old Snake lives much longer than the 6 months predicted, showing just how strong he was. He died on March 12th 2020, his role in the destruction of the Sons of the Patriot System was released to the public and he was hailed as an International Hero. He is buried in the Arlington Nation Cemetary near the graves of The Boss and Big Boss, whose full files were also de-classified and released to the public. March 12th is declared an International holiday, Snake Day.

2060: Over-population is becoming a major issue and planes to colonize the moon. Planes to colonize Mars are also underway.

2065: The moon, now called Luna, has been successfully colonize and is steadily growing. The Mars mission is nearly ready for launch. Until Artificial gravity is perfected most "Spacers" have most of their muscular system replaced with artificial muscles to avoid muscle degeneration brought on by the ZeroG environments.

2075: Mars Mission is a success and the first colony of Aries is founded, quickly followed by Sparta and Troy.

2094: Alien ruins are found buried beneath the colony of Sparta. Archeologists are eager to search them and are stunned to see how advanced the ancient technology is and after months of searching they find a large monolithic structure and discover it is a kind of archive. The information found within reveals groundbreaking new discoveries but most of the data found so far is corrupted beyond repair.

2097: After 3 years of research and study it was discovered that using the strange new "Element Zero" that was found in a storage facility in the Prothean ruins artificial and anti-gravity can be created. Shortly afterwards a scientist by the name of Orion Gran discovered a mode of FTL using Einstein-Rosen Bridges, with the help of another scientist named Olga Dinavitch, they developed the Gran-Dinavitch Worm-Hole Drive, an Worm-Hole projector that allow incredibly fast travel between point. Originally they were going to use Eezo as the main force behind FTL but when it was discovered that larger ships with Eezo cores couldn't land on planets the idea was scrapped.

2099: Though not perfect a world very similar to what The Boss had envisioned, a world with truly united nations that respected one another despite their differences. This Unity was called The United Astrological Alliance. Though there are still terrorist groups and rouge nations that cause trouble.

2157: A strange artifact is found is found the in the Shanxi system.

(A/N: I had a lot of trouble planning out the First Contact War so with permission I copied some of xpredatorx's First Contact War from his story Halo: A New Age, and edited it to fit my story. So Most of the rest of the chapter, and parts of other FC War chapters most likely, belong to him/her, and MistaSilentKiller who helped him/her write his/her story. I strongly recommend the story as is one of the better Halo/Mass Effect x-overs. That's Halo: A New Age by xpredatorx.)

May 19, 2157

Shanxi system

UAA Cruiser Pathfinder

Main Bridge

Admiral Jon Grissom a man at the age of 46 with dark brown hair and height of 6'2 is sitting in the captain's chair overlooking at the operations on the holographic projector. About a month ago one of the UAA's deep space probes was launched from Shanxi the newest colony to be developed was searching the asteroid field for possible mining instead they found a strange artifact that had two long, curved "arms" with what we believe to be a set of revolving rings in between them, covered in ice. The admiral was assigned to protect the civilian workers charged with digging the artifact out of the ice and science teams charged with studying the device.

"What is the status of the workers and scientists and can they tell me what this artifact is?" asked Grissom

"The workers are finished cleaning the ice off the artifact, but the scientist are requesting permission to turn it on for more information." said the comm. officer

"Permission granted just tell them to be careful the last thing we need is for this device to blow up in our faces." said Grissom while trying to relax in his chair

"Admiral haven't you heard the expression nothing ventured nothing gain." said Athena the Pathfinder's A.I.

Athena appeared next to the Admiral as a full size adult a height of 5'9 in holographic form, Grissom turned his head to look at Athena she had the appearance of a young scientist with a white long sleeve coat, with raven black hair that settled at her shoulder length. A.I technologies have come a long way from the of the Proxy-War era in the early 2010s and are now even more sophisticated than the Patriot , capable of the full range of human emotions which also helped deter them from repeating what the Patriot did as they are capable of compassion and most would not want to repeat the Proxy-War era.

"I'm as curious as the next guy about what this giant tuning fork can do, but I'm not going to take chances." replied Grissom with a look of annoyance

"Yes admiral I understand your caution, but if humanity shied away from every potential risk, you'd still be living in caves right now." said Athena

Before the admiral could say a thing the comm. officer alerted the Admiral of the activation of the artifact. "Admiral the scientists are ready!"

"Very well, alert the captains of the Hellfire, the Viking, and the Hercules to be ready." replied Grissom

Exodus Cluster

Utopia system

Turian Patrol fleet

A Turian patrol of three cruisers and six frigates is patrolling the Utopia system in search for any pirate activity.

Tonn Actuss a Turian captain in the Turian Hierarchy is in charge of finding any pirates that might be hiding in this unclaimed cluster, Actuss is a proud Turian. The military life runs in his family, he is very serious when it comes to upholding the law in council space and will do just about anything to make sure everyone follows it.

"Captain relay 314 just activated." said the sensors operator

Actuss turns around and walks toward the operator. "Impossible relay 314 is a dead relay it leads to nowhere." Actuss responded

"Sir, I am positive and something just came out of the relay." said the operator

"What is it?" asked Actuss

The operator turns back around at his console to check. "I think it's a probe we may be dealing with first contact captain." reported the operator

Actuss just stands there thinking, 'This is obviously a new immature race that doesn't know the dangers when activating a relay, and worst a dormant one, that's against council law they need to be taken care of'. He heads back to his chair and sits down and begins giving out orders. "Tell the patrol to head for relay 314 we must deal with this new incompetent race." said Actuss

The patrol starts heading to the mass relay in hoping to put down these law breakers, but they might get more than what they barging for.

UAA cruiser Pathfinder

Main Bridge

Admiral Grissom was just finish reading the reports the scientists found on the artifact. A transportation device capable of sending you a thousand light years instantaneously to another star system. "Are these reports accurate?" asked Grissom

Athena was the one to respond. "Yes sir they are, this is obviously a very interesting piece of technology that will change a lot in the UAA."

"Yes it will, a device capable of sending you instantaneously to another system! I know the Gran-Dinavitch drive has advance ever since we first discovered it, but it still takes at least one or two days to get to our farther colonies, but this could help us fix that." said Grissom

Before anyone could celebrate the success of the mission the artifact's inner rings moved rapidly and out came nine unidentified ships that started attacking the civilian and science ships. Before anyone could respond both vessels were destroyed.

"WHAT THE HELL JUST HAPPEN?" asked Grissom shouting at the top of his lungs

The sensors operator turned to face the admiral. "Admiral nine unidentified contacts came out of the relay and began attacking the civilian and science teams ships, I believe this is first contact with a new alien race."

"Admiral do you want me to try and make contact with them?" asked the comm. operator

"Their obviously a hostile species! They just attacked innocent civilians." said the Admiral. "I want you to tell the captains of the three Frigates that came with us to get their weapons online." The Lieutenant did as he was told and began sending the message to the ships.

"Athena charge the Rail Cannons and get one through four Achilles missile pods ready." said Grissom. Athena did as she was told and was already getting the Achilles missiles prepped and ready to fire. The Achilles is successor to the Archer missiles. On cruisers there are more than five hundred pods contain fifty missiles, in each missile contains an EMP charge that are designed to do damage on shields emitters quickly followed by a shaped charge of C-22 designed to rip armor plating apart and expose the interior to vacuum.

The outside on the Pathfinder four hidden compartments opened up and out shot four pods racing to the alien ships in these four pods contained over two hundred missiles.

Turian cruiser The Judicator

Captain Actuss is standing in front of the projector looking at the battle, he thinks to himself. 'How can a race build ships that large and manage to fly them'. Obviously he is referring to the three frigates and cruiser, the frigates length is 438 meters, width 152 meters, and height is 112.3 meters; the cruiser's length 1,192 meters, width 300 meters, and height 450 meters, they were also strangely organic looking while also obviously not. The designs were odd to say the least. Actuss turned and face his comm. officer. "Tell the frigates to swarm the three smaller vessels while we and the other two cruisers handle the bigger one." The Turian acknowledged this and was about to send the message until the sensors operator detected what appeared to be missiles of some kind launched from the bigger vessel.

"Captain I am detecting what appears to be four large missiles heading to the cruiser midnight shadow." said the operator.

Actuss just chuckled. "What do they hope to hit a planet with those oversize things just get ours and the other two cruisers guardian lasers to shoot them down."

Just as the weapons officer was about to turn the guardian lasers on, the Turians were shocked to now see over two hundred missiles come out of the pods. The guardian lasers attempted to shoot down the missiles but was too over whelming and only took down fifty-eight the other hundred and forty-two slammed against the midnight shadow. The ships kinetic barriers could do almost nothing as the EMP charge weakened there shields and the C-22 finished them off and tore massive holes in the haul.

Captain Actuss was furious that one of his own ships took serious damages. "It would seem we underestimated this new race." said Actuss. "Tell the frigates to continue as plan and target those three ships while we handle the bigger one!" said Actuss fire burning in his eyes, he looks at the weapons officer. "Fire disruptor torpedoes it's time to return the favor for what they did to my cruiser."

UAA cruiser Pathfinder

Main bridge

Admiral Grissom is looking at the battle on the holo projector, he sees the damages to one of the alien ships by the Achilles missiles, and six of the smaller ships breaking off course heading to the three Frigates.

"That's interesting!" said Athena. "By studying the impact of when the Achilles missiles collided and after, it would seem their shields seem to be using Element Zero to generate them."

The Admiral turned his head and looked at Athena. "So what you're saying is their shields technology is derived from the Protheans." asked Grissom.

"Yes admiral but I believe that our Rail Cannons..." Before she could finish that sentence the sensors operator reported of incoming weapons fire from the larger vessels. Grissom orders for the shields to be at maximum strength and tells the crew to brace themselves.

The entire crew on the Pathfinder braced for impact as the disruptor torpedoes slammed against the shields of the Pathfinder. As soon as the bombardment was over the crew began assessing the damages, but Athena was already ahead of everyone. "We have hull breaches on decks four and seven shield strength is down at 86%." said Athena

"What the hell did they hit us with?" asked Grissom

"What I can tell from the sensors is that it was torpedoes that when impacted against our shields created some kind of warhead that creates random and unstable fields in a localized area." said Athena. "These Torpedoes put incredible strain on the haul, we were lucky their wasn't that many or the ship would have been torn apart."

"We can't let that happen again!" said Grissom determined to make sure of it. "Get the laser canons and gauss guns online and target those missiles." said Grissom to the weapons officer. "Athena what's the status of the Rail gun." asked Grissom

"Charged and ready Admiral! Do you have a target in mind." asked Athena

"Target the already damage one make that ship go away." said Grissom

Athena maneuvers the Pathfinder's Rail gun and aims it at the Turian cruiser. The Rail Cannon is one of the UAA's primary weapon on ships. Over hundred years ago the Rail gun was just a large small arms sniper rifle that shot rounds with enough force to knock over large trees. Today the standard Rail Cannon on ships has 750-ton tungsten flachete with a depleted uranium core firing at 55,000 meters per second with a destructive force of 86.73 kilotons of TNT, but requires a one minute charge for every fire.

Captain Actuss is listening to the weapons officer of the successful direct hit from the disruptor torpedoes, and understanding that the enemy's shields went down a notch from the warhead of the mass effect fields. Now they have a way to beat them. "Order every ship to use disruptor torpedoes to target the enemy ships they seem the most effective."

"Sir I'm detecting a buildup of energy that far exceeds anything that of a Turian dreadnought can put out from the larger vessel." said the sensors operator. "I believe they are planning to fire!"

"Get are shields at full strength and ready guardian to shoot it down." said Actuss

As the crew on the bridge works to get everything ready the Midnight Shadow blows up in a gulf of fire. The entire crew looks out in shock as to what happen Actuss runs towards the weapons officer. "What just happen?" asked Actuss

"I believe it was a mass accelerator that puts any of our dreadnoughts to shame." said the weapons officer

Actuss wasn't happy about this, but he still believe he can win this fight "have the frigates concentrate all their fire on one of those ships while we take ours and move back and to get away from the range from that weapon." said Actuss

The two Turian cruisers moved out of weapons range while the six frigates concentrated all there fire power on the UAA Viking.

Main Bridge

On the bridge the crew is rejoicing over the destruction of the Turian cruiser, but the excitement had to wait as the comm. operator spoke out that the Viking is being overwhelmed and their shields are about to collapse.

The admiral acted fast. "Open up a line to the captain of the Viking." asked Grissom. "Admiral this is captain Littlefield we are being overwhelmed by the enemy, laser cannons are picking the missiles out of the sky, but there's too many; shields will soon collapse." Grissom thinks fast. "Captain get your crew to transfer power from non-critical systems to the shields and try to get the Hellfire to give you some support." said Grissom

"Were doing that now captain but I don't think the Vik...'' Before captain Littlefield could say anything the Viking was destroyed from a mass accelerator from the Turian cruiser the Judicator.

Everyone on the bridge saw the destruction of the Viking and could not believe it, the admiral however did not let this break his resolve. "Athena call in the reinforcements it's time we end this". said Grissom

Just as he finished his words out in space around the battle six Wormholes opened up and out came four frigates and two cruisers. This caught the Turian's by surprise and cost them four frigate and one cruiser. Captain Actuss was not happy but like all military strategists they know when to retreat and the Turian's began retreating back to the relay, before the last frigate could escape admiral Grissom ordered Athena to take its engines out with the laser canon. The laser canon on the Pathfinder shot out in a red beam and struck the engine of the Turian frigate leaving it dead in the water.

"Admiral do you want us to finish the job." said the weapons officer

Grissom looks at him and says. "No we need answers on who they are and why they attacked us get boarding parties ready were sending them over."

UAA Pathfinder

Armory

Major Jenifer Hale a UAA BREACHER is getting her and her team of twelve ready to board the enemy ship, she straps on the standard BREACHER armor and checks her shields. Ever since the UAA developed their own shield technology they found a way to equipped all their foot soldiers with shields, not as strong as those given to specialized groups like FOXHOUND, the revived B&B corps, and the new Dead Cells but protects them from getting their asses shot. Admiral Grissom walks in the armory and sees the boarding party getting ready the BREACHER's stop what they're doing and salutes the admiral.

"Major I wanted to debrief you on what your team will be doing." said Grissom as he continues. "You will be transported via the HARPOON to what Athena believes is the bridge and once aboard you will set up a link between the Pathfinder's computers to the enemy's understood."

"Yes sir we do and we won't fail." replied Hale

Turian Frigate

CIC

The Turian Captain was giving out orders to be ready to repel enemy boarding party's but just as he was about to finish three large spear-like objects punched through the haul of the ship, killing a few turians at their stations, atmosphere was leaking for a split second before a membrane of somekind quickly grew over the holes where the spears still stuck out and sealed the breach, the "head" of the spears then split open and out of them came twelve strange looking creatures in the eyes of the Turian's that almost resembles the Asari started taking down his people, four from each spear. There were shots fired but thanks to the shields of the BREACHER they were okay the captain looked up from the ground he was knocked down by one of the aliens he looks up at one of them the alien went up to the ships computers and started messing with it.

"This is Major Hale setting up the link now." As she did that streams of information was going through the holographic projection.

UAA Pathfinder

Athena was going through the information the aliens had and found something surprising." Admiral you need to see this!" said Athena. She sets up a link between her and the admiral's neural implants, he begins looking at the information in English thanks to the translation program and found something shocking.

"It looks like we did the Unions job for them and more." said Athena

"I have to tell you when we started this fight I thought we were fighting a hostile race I didn't expect this." said the Admiral. "Send this Intel to General Williams of the Shanxi Garrison, the UAA High command and the UAA Senate they will definitely want to see this." As the UAA ships tows the Turian frigate to the Shanxi anchorage admiral Grissom looks back at the artifact now known as the Mass Relay and asks himself what the future might become from this encounter.

(And that was Chapter one. And Now CODEX!)

Codex

BREACHER: Breachers are highly trained elite soliders trained to board and take over enemy ships quickly and efficiently. They are transported into a ship via a spear like vessel called a HARPOON. As the name suggests a HARPOON pierces the haul of a ship with minimal damage, once the onboard A.I detects that the vessel has completely stopped it released a semi-organic membrane that adheres to the entry point and creates a reliable barrier to the vacuum of space.

Rail Cannon: Rail and Gauss gun technology as advanced quite a lot since 2014, most larger weapons such as Sniper rifles, tanks, and heavy machine guns use this technology with varying degrees of power. But the Rail Cannon is the panicle of modern Rail gun technology, a massive Rail gun capable of firing equally massive rounds that have been seen to shatter asteroids. In fact, the first functioning prototype was test on a large asteroid that was predicted to hit earth in 5 years 87 years ago, the round hit it with enough force to shatter the asteroid into pieces small enough to burn up in atmosphere.

UAA Shields: The first prototype seen in use was way back in 2007 during the Big Shell Incident. A Dead Cell member by the name of Fortune who unknowingly had a magnetic field emiiter on her person. It was capable of deflecting the paths of bullets around the wearer, and render nearby explosives inert. The device worked by creating an electromagnetic field around the user, which would be strong enough to repel all metallic objects, though the user's own weapons and their immediate environment would remain unaffected. The field could deflect bullets, missiles, rail gun shells and other types of weapons away from its intended target. Grenades and other explosives were also disabled, making them appear to be duds. Likewise, it is also capable of resisting even weaponry capable of shorting out most electronic devices, such as chaff grenades

Will have more in later chapters.
