Special Note: The following stories will elaborate ALL the Metal Slug 6 stages and can be considered as a walkthrough by others. Also note that spoilers will also be included. Like the game, this fic is based on Metal Slug 6, but I will not elaborate where the prisoner is and weapon crates, it will spoil this fic even more.

Metal Slug 6

Prologue;

Before the Rise

"Come on, the exit is just ahead!" Marco shout at his teammates, Eri, Fio and Tarma as they run backwards with their firearms blazing.

"Go ahead Marco! We'll catch up!" Tarma respond, throwing several grenades on Clone Marco.

Saving General Morden wasn't their plan they really hoped for, they wanted to save Marco, and thats what they did, using the rebel astro to attack the Martians mothership and to rescue their captive companion. The Martian clone him right after he was captured and create thousand of his kind. Luckily, their not as fast as the Marco they knew. They manage to rescue both General Morden and Marco, but now the entire spacecraft is exploding, with the Rebel Army nowhere to be found. It is a high possibility that they manage to escape.

Eri kept on firing her special issue heavy machine gun as well as Fio while Tarma try his best to destroy the gate. Out of nowhere, Zombie Clone Marco appears, and it doesn't look too healthy. Fio and Eri looked at each other as the Zombie begin to vomit. They push Tarma down before it hit him just in the nick of time.

"Thanks girls, I owe ya one."

"Keep shooting the gate Tarma" Fio suggest, leading him a Drop Shot weapon crate.

"Great, a Drop Shot." said Tarma, looking forward to use either a Rocket Launcher or a Flame shot.

Both Eri and Fio concentrate fire on the Zombie Clone Marco the best they can when Eri's weapon goes on clicking, empty. She pull out her handgun and starts to shoot the Zombie right between their eyes, as it's head fall off before his body starts to melt away. Fio too starts to have the same problem, her weapon is almost dried up but the gate isn't open yet. Tarma has wasted the Drop shot but it was no good, the door still wouldn't rise. He begin to hesitate, and throws all his grenade wildly at the door. The door gives way, and more Zombies too at the other side. "Kill, kill, kill" they chant.

"Guys, we got company!" Tarma shouted, praying that he would settle his weekend getaway for a Slug aloud, any Slug. He's prayer has answered as a Slugnoid suddenly drop from the Spaceships hull, smashing the unexpected clones beneath, thinking that god GOES exist. Eri and Fio however is dumbfounder by Tarma's wish.

"You could do that?" Ask Eri, throwing her last grenade.

"If you could, can you pray for a even heavier Slug?" Fio asked.

"Stop teasing me!"

With the Slugnoid available, Tarma gives a lot of covering ground for Fio and Eri, both eventually picked up a Flame Shot left by a dead Clone Marco, but rose up as the Zombie! Eri and Fio immediately go postal and melee the creature before it starts to spray blood on them. They eventually arrive at the third door. Zombies and clone starts to pour down like water, but Tarma manage to settle them before the door is down. Fio spotted a Rebel LV Armor and take it for a spin. All three eventually had to fight with several King Brain Laser, a towering machine with a brain on it's upper sphere. With Tarma busy killing off zombies from behind, both Eri and Fio had to level it with Flame Shot and pistol, dodging it's predictable attack. They eventually reach the final gate, but a massive flood of Zombies and clone soon overwhelm them. With Fio's rebel LV armor no longer had any ammo and Tarma's Slug taking heavy damage, both Fio and Tarma execute the Frontal Attack on the final gate, thus destroying it. The Zombie and Clone immediately died when they open the last door, wondered whats going on

"What the hell? Why did they die?" Tarma asked

"Look, I don't even been to school, how should I know?" Eri replied

-----------------------------------

"Sir, is it wise to just to leave them alone?" one of the Rebel soldier spoke out.

"Of course you incompetent, they only here for their friends, not me. I'm surprise that they would simple leave me in search of their lost friend" General Morden replied, narrowing his remaining troops.

He took a look around the Martians mothership closer, thinking that he would use it's technological edge against the Regular Army. Nevertheless, this old bucket is going to crash along with it's technology. He immediately command his troops to take what seems useful from the Martians weapon, material and even the broken eye robot. However, Clone Marco beginning to flood the area, and Zombie Marco just right behind it. "Kill, kill, kill" the clone chants.

"Sir! It's the Clone! It's the attack of the Clones!" several grunt said it in shock

"Get back sir!" another yelled, pulling out his bazooka.

As several grunt open fires to protect and defend their general from harm, general Morden take place inside what appears to be a tank shape like a UFO with several grunt riding their rebel astro and the Martians mini UFO. Just as they begin to deploy their way out, a loud explosion suddenly erupted, followed by a terrifying shriek. As the explosion wasn't much to worried, a strong space vacuum suddenly begin to suck the clones and the poor unprotected rebel soldiers. The vacuum instantly drag the clones to their doom, along with everything else inside the mothership.

-----------------------------------

"Oh my god, Marco, Fio!" yelled Tarma as he watch his best partner been suck into the space vacuum as he sit comfortable inside the Metal Slug. Eri simple watch away with her tears, praying nothing else will happen to them.

"Tarma, get a grip. Both of them died to save us." she sobbed inside the Metal Slug using the communication radio. She could feel a sharp pain in her chest. She lost her partner as well after all.

As both Tarma and Eri's Slug kept going down plundering to Earth, Marco and Fio however survived, but they are hanging for their dear lives near the gate, trying their best to hold themselves the vacuum suck in more clones, Martians and several alien technological army to space. Just as the space hatch begin to close, Marco and Fio suddenly heard a loud shrieking sound, even in the vacuum, it can hear it clearly. Zooming in front of them, several rebel soldiers plundering towards the void of space followed by a huge, oversize Martians with two arms, easily the biggest Martian both Marco and Fio would descript as a monster forcefully exit the mothership, damaging almost all the hatch door and hanger in it's wake. It activates it's booster pack and aiming towards the two Slug. Marco and Fio knew Tarma and Fio will be in big trouble. Just as the space hatch closes, suddenly the hanger door violently open when the explosion erupted sending several Mini UFO slam along with the space hatch, thus knocking both Marco and Fio. The slamming continues, weaken the hatch even more and forcefully opens the hatch sending Marco and Fio into the void of space itself, along with all the mini UFOs

Both Tarma and Eri wasn't too thrill about their lost. They just saved them, why would Marco risk his life to save us? Tarma simple watch as the mothership beginning to engulf by the flame, plundering towards the gravitational pull from the Earth's own gravity. Just as Tarma and Eri begin to activate the Slug's deflatable bag, both of their Slug suddenly shake violently, jerking both of them. Eri look around in her Slug's visor. She sees nothing, thinking they were hit by some heavy object. She tries to open her emergency deployment, but nothing happen.

"Tarma, I think I've been hit by debris, and my deflatable bag wouldn't open." she claims.

"If it's a debris, then they wouldn't have two eyes, would it?" ask Tarma, firing his Vulcan at it

Eri took a look again puzzled why Tarma open fired. She opens her cockpit, and saw two brown 'stick' jolting the Slug. It eventually lead to an oversize Martian, looking at them as it pull both of them towards Earth. Eri goes back in and fires her Vulcan at the Martian, and the alien retaliate both of them with a massive shockwave, damaging the Slug. Tarma finished reloading his last cannon and fires it at an unexpected spot, the brain. The Martian shriek in pain, giving Tarma a clue.

"Eri, get out of the Slug. We need it if we want to survive from this free fall!" He yelled at her, exiting his Slug and goes postal at the alien's brain.

Eri had other plans, she focus her Vulcan towards the brain and auto-fires it, releasing the cannon along the way. The alien begins another shockwave when a two beam strike the Martians brain, followed by a familiar voice.

"Hey guys, remember us?" Marco greet at Tarma, still going postal.

"Go away Marco, I'm avenging you with this knife I got here... Marco?" he replied. "Marco! Your alive!" he continue

"Fio, your alive as well!" Eri shout out, seeing her and Marco riding the mini-UFO

"Yeah, I'm alright. If it wasn't because of that hanger filled with these things, we'll never made it out alive." she said

"Okay guys time to finish this. Everyone, open fire!" Marco commanded followed by a unison happily replied "YES SIR!"

The massive Martian begins to panic and launches another shockwave, with Tarma jumped over it but destroys Eri's Metal Slug. She exit her Slug and join Tarma for a good slashing moment. Both Macro and Fio also try their best to fire their weapon at the Martians. The Martians starts to split out plenty of energy balls, but Tarma and Eri manage to escape from it and continue their work. Helpless, the Martian begin to launch several more random attack. After some dodging and evasive action, Tarma give the final blow, in return the Martian shriek in pain, smokes and blood came running out from it's tube. Tarma took a look at Eri's Slug damage beyond repaired. 1200 feet.

"How will you escape then?" Tarma asked. 1000 feet

"I could squish my way inside that Slug with you." she suggest, feeling uncomfortable saying it as well. 800 feet

"The Metal Slug is for ONE pilot only!" Tarma said as he could feel the Martian beginning to loose balance. 600 feet

"Just do it!" Marco yelled. 490 feet.

------------------------------------------------

"So you yelled at them and both squish themselves inside the Slug" the Commanding Officer with his tag name Wilson pointed out as he read through the paper works. He wears his military uniform with one button not tied up and had glasses, appears to be bold.

"Yes sir, I did sir" replied Marco. Both Tarma and Eri looked embarrass the fact that both had to squish themselves inside the Slug for their survival. Fio stand beside giggling way.

"I hope none of you do anything naughty." Fio said aloud childishly. The two duo immediately yelled out "No we didn't!"

"... your report also said that the rebel army help you as well?" Wilson asked.

Tarma step forwards, nodded "Yes sir, in order to rescue Marco, the rebel army agree to help us"

"And how about General Morden, have you successfully annihilate him?" He ask

There was a long silent when that question came out. Tarma, Eri and Fio looked at each other, thinking that they might at least arrested him back in the ship However, they won't let a single minute to leave Marco behind just because of General Morden? Wilson starts to tap his pen, waiting for an answer. He looked at the report again, seeing that the report based on an event that Martians came to Earth and invade the planet by kidnapping their best men and officers. He close his file, remove his glasses and asked again. "Did you or did you not kill Morden?"

"No sir we did not." Tarma answered. "Along with the other Second Rebel Coup"

"Then that what I figured. Return to your posted. Take the weekdays off for all I cared." He said as he toss the file aside, stood up and exit towards the hallway, slamming it. Leaving all four veteran soldier to look at each other.

"Well, looked at the bright side, at least we had a weekdays off." Tarma respond, followed by a series of punches from Marco, Eri and Fio.

Back in the cabin, all four veteran look at their reports, they've been fighting weird things lately from a giant mutated crabs, zombies, huge freaking robot, old Japaneses troops, worms, plant eating monster and Martians. To Marco, the report feels like a fairy tale. The government wouldn't believe what they seen or heard in the communication since they were dispatch against Morden's men. They do know that one day, they'll have to fight against Morden again.

"Marco, how did you escape from near death again?" Tarma asked, breaking the silent moment.

"I don't really want to recall that experience" he answered.

"But seeing you alive and well right after you've been suck into the space is something even I can't believe." Eri pointed out.

"Perhaps it's luck" Fio replied.

"Well, I'm bored. I think I'll hit the shopping mall and see what I can grab." said Eri as she stood up, placing her sidearm aside. Fio followed too, pulling out her usual clothing from her dresser. Fio offers Marco and Tarma to join as well, but he refuse.

"Sorry girls, but I had to go report this to Penegine Falcon HQ that our mission was a success." Marco said, smiling out at the two girls. "I'm coming with you Captain." said Tarma.

--------------------------------------------

Somewhere in the Pacific Ocean,

"You sure that this Rootmark isn't or wasn't dead yet?" General Morden pointed out to the remaining Martians on their own cargo ship.

"That is correct Earthling. Our leader has the ability to recover even the most indefinable death. To us, he is our superior and other than that, he is one of us." the Martian spoke out.

Just then, the chain suddenly jerk down, causing the ship to rock. The voice of shrieking can be heard. Other rebel troops begin to tremble just by it's monstrous voice, then it is calm again. Rebel soldiers take the liberty to have a close look at the monstrous Martian while Morden himself was confident that the Martian will indeed join forces with him till the end. When Rootmark eventually resurface from the water's depths, Rebel forces cheers along with the Martians in their fashioned ways. Just as they were celebrating, the Martian instantly starts to shake in fears, making the rebel army along with Morden puzzled by it's reaction when suddenly two unknown alien beings dive from the sky and lift up two Martians and starts to eat them alive. The troops begin to lost their focus, not quite ready what they just saw. Then more of these thing landed on the deck, attack the rebel and knock Morden down. He yelled as he fell towards the cold sea along with Rootmark.

------------------------------------

In the Penegine Falcon HQ, Marco and Tarma gives the report to the authorities about their mission status. Many other Penegine Falcon greet them as their idol, their heroes, the best man for the job. Marco didn't really wanted to be the best of everything, he wanted to stop this war from going on. Thats what he thinks. With General Morden still out there planning for another grand plan for world domination, he thought. As he sign his name on the tabloid, Tarma poke at his shoulder, asking his friend a question.

"Hey Marco, I heard about some sort of new weapon been develop, wanna go and check it out?"

"No thanks Tarma, I still have to deal with this fan mails here," he replied with a sweat drop appears as the officer hand him over a basket filed with letters.

"It's a Slug they've been develop, something that is similar to the rebel LV Armor" Tarma continue

"Seriously?" he asked

As both veteran heroes head to the R & D center, almost all the trainees and officer take this opportunity to watch the Slug in action on the other side of the fence. To Marco and Tarma's surprise, it walks just like the rebel LV armor and jumps high as well. It appears to be having a chain gun and a huge cannon folder. The only thing missing is the roof, which will not protect any piloted man from harm. Intriguing by the Slug, Tarma wanted to know the name of this particular Slug. He walk towards the person in charge, a woman with tight military uniform and wears a lab uniform as an overcoat. He gives a weird posing while he's at it.

"Hey babe, what's this babies named?" he asked

"There is several things we could call it. One, you can call me Stancy McWeel, Two, I am in charge of this operational and my status is higher than you and finally, we don't have a name for it yet" She answered.

"Okay, you said that your rank is higher than mine is no problem, but whats up with a Slug with no name?" Tarma asked

"Initially we wanted to call it the LV Slug, since it was based on the rebel LV armor. But we want it to be genuine. Others called it something even I can't said it out loud." She replied.

"Like what?"

"Slug Slinger, Slug Metal, Slug Destroyer, etc, you make a pick" she said as she handle over a pile of list about the name of this Slug, it when over 100 names on it. Tarma simple open his jaws wide open, Slug Frogger? Slug Dominon? What kind of name is that? Marco heard the conversation when he approach to Tarma. He borrows the list and look through them, comparing it to the Slug he sees and gives it a try, lightening his partner's mind.

"How about... I don't know, the Slug Gunner?"

---------------------------------------

Several Hours later...

Eri and Fio finally return from their shopping spree and had been borrowing the Metal Slug to counter the road tax. They didn't actually buy anything essential other than new model pistol issue and several grenade order from their daily uses. Both girls make themselves comfortable in Marco and Tarma's cabin before returning to the Sparrows in the next 3 days. They spot Tarma, but Marco isn't inside the cabin. He explain it to Eri and Fio along with the new prototype Slug Gunner.

"... and so the new Slug has the new name from Marco?" Fio said.

"Yep, believe it or not, that name kinda suit that thing as well, unlike one particular named like the Juggernaut Slug." Tarma suggested.

"Speaking of Marco, where is he?" Eri spoke out, "I bought him a new water bottle ever since that cloning incident."

"I saw him entered the recruitment center, said some new veteran troops was assign to join in." Tarma announce.

"That is correct Tarma," Marco answered, entering the room with two soldiers into the cabin. "These guys here will assist us in the coming mission."

The three of them gaze at the two soldiers. One of them is wearing a striped bandana, with gray leather jacket while the other one is wearing a cap and had a purple leather, wearing the same dark glasses as Tarma. Both have the same height, but different personal. Eri, Fio and Tarma stood up solute in respect , which they solute back.

"Greetings, My name is Eri Kasamoto. This is Fio Germi, my partner from the Sparrows." Eri announce.

"And I'm Tarma Roving, same company with Marco Rossi."

"Good to meet you. I'm Clark Steel and this is my companion, Ralf Jones. We are here to assign the same task force as you will. I heard plenty of rumor that you were fighting supernatural."

"There's just some rumor to be true" Fio said childishly. "We fought the mummies, the zombies, mutated creature and Martians, and live to tell it." she continues.

Ralf, who wasn't taking any serious simple poke his finger to his ears, feeling irritated "Right, mummies, zombies and Martians, just what HQ needs, more rumors and fake stories."

"Hey, it's just a government cover up okay?" Tarma said when the alarm suddenly burst out loud. An announcement clearly stated that all personal to be reported to the main hall for mission briefing. After hearing the announcement, Tarma look down, sadly said "There goes our weekdays off, I shouldn't have asked for a Slug that day"

"Well, you shouldn't even pray too!" Fio teased him.

Immediately, all veteran arrive at the main hall for their state briefing. The commanding officer came up and gives a speech "Good evening men. By now you all know that Morden's man is no where to be found and are hiding near either on American or Europe soil. But we manage to found this picture captured by one of our operatives in Rangoon." he said and reveal a badly destroyed cargo ship with a Rebel Armies label on it. Immediately, Marco ask Tarma, Eri and Fio to get a plane ready for take off. The commanding officer continues.

"We believe that the remaining Rebel troops is somewhere there, and most lightly station there with small outpost from Rangoon. We also found some disturbance in China, detail to be some sort of Rebel armies biological weapon appearing from China recently. We will launch a preemptive attack on their front door while others attack at the rear, battle plan and orders will be given to you. Dismiss."

As the war veteran beginning to race down to grab their gears, Clark and Ralf when towards the airstrip with nothing more than their sidearms and grenades. This is also the first time get to taste this action on different armies. But since the other plane isn't ready to take off, they had to join up with Marco and his team who gladly offer them a lift.

"There still room for two" Eri yelled at them.

"Alright, here we go!" Ralf answered.

"Wait a minute, whats with the tank?" Clark asked, referring to the Metal Slug. This is his first looked at the small-looking human-height tank. Unlike any other armored vehicles, this vehicle is considered the pride of every armies needed, or so the rumor goes.

"Don't worry, will need it once the situation gets nasty." Tarma answered, "this thing never seize to amaze me" he added

"You use tanks? Come on, your fist do the talking, not a tank" Ralf spoke up, making Clark chuckle.

After Marco read through his mission briefing, he narrow it down to a simple sentence they would understand, especially those who had fought against Morden with Marco on his side that is. "Right, our mission is to destroy our enemy, the Rebel Army and rescue hostages. Pilot, next stop, Rangoon!"
