    1.About me
    -----------------------------------------------------------------------
    
    Hi, my name is Calvin Cheah from Malaysia and this is my first FAQ/Walkthrough
    I made. Please excuse my English if I made any error whatsoever during this
    FAQ.  I'm also a typical person who works in the office, studies in the college
    and most importantly playing some of my favorite games. Currently this FAQ is
    close to completion and now playing the combat school to unlock any goodies the
    game has to offer, so contribute some FAQ that I miss out anything in
    particular by emailing me at cheahyuanhong@yahoo.com. In addition, any
    character respond does not really happen in the game.
    
    Metal Slug series has been one of my favorite games so far, even when there are
    better games with great graphic and 3D character. Metal Slug should be played
    in an arcade version with normal difficulties setting. People that play on easy
    mode will understand the enemy attack. This is also gives players to understand
    the enemy behavior. However. As a veteran Metal Slug, fans like any other goes
    to a challenging mode known as the Hard mode where the enemies will attack you
    even when they aren't suppose to. Even though Metal Slug 6 owns many people
    with never ending episode and all time favorite run-and-gun, Metal Slug 3 still
    rocks my world.
    
    In this series, several new characters, Slugs, and enemy came into play and
    introduce. The game also lets players to use a newer system that enable players
    to get more coins by killing and such. This can be count by the bar located at
    the lower left (1P) or lower right (2P). Other than the game play, several
    figure also available for the players to enjoy, such as the art gallery, which
    features the artwork done from the early days of the known famous Metal Slug as
    well as soundtrack that eventually kept on track from the first Metal Slug to
    Metal Slug 6 itself.
    
    -----------------------------------------------------------------------
    2.Story so far
    -----------------------------------------------------------------------
    
    Metal Slug 6 takes place right after a few weeks or so in Metal Slug 3 when
    the Martian needed Morden's man to bring their leader back, Rootmark from the
    deep in the ocean. When they manage to pull it out, a new breed of enemy attack
    Morden's men and some Martian turns to lunch. Morden's men along with the rest
    of the surviving Martian tries to escape the tragic event and station on
    several location as an outpost, building up weapons of mass destruction to
    fight this new invader.
    However, giving the fact that Morden is still alive after their last set back,
    the government wasn't too please with the results and ordered two war veterans,
    Clark Steel and Ralf Jones to join up the fight. Marco wasn't too please with
    this results, as both never once fight the likes of the Rebel Army before.
    Nevertheless, both joins up and continue to pursue Morden's activity and what
    seems to be the final showdown between the Regular Army and the Rebel Army
    before the enemy feared by Rebel and the Martian appears again.

    3.FAQ
    -----------------------------------------------------------------------
    
    Q. What's a Metal Slug?
    A. Many people asked this question from the start. It was suppose to be a joke
    to create a game which related to a slug, but it eventually turn into a tank
    that could crawl like a slug (hold down and directional key) Other than that,
    Metal Slug is one of the surviving game series in 2D which features several
    unforgettable arcade moment. Metal Slug 6 keeps itís classic just as it is 10
    years ago.
    
    Q. I can't do the Frontal Attack!! HELP!
    A. OHMYGOD, Calm down! Simple press the R1 button and your wish came true.
    
    Q. How do you do Ralf's special attack?
    A. Simple press up button and R2 button. This also works on Clark.
    
    Q. Why can't I perform this ability to the original characters?
    A. That because they can't silly.
    
    Q. Does the old glitch still there, popping out from the Slug and receives no
    damage?
    A. Yes, the old glitch is still there. SNK developers think that this glitch is
    actually useful, so they keep it.
    
    Q. How come I have to rescue the Martians in the final stage?
    A. They somehow got themselves imprison by the Unknown. Think of it as a
    prisoner.
    
    Q. What is this goofy looking vehicle I found in Mission 3?
    A. Thatís the Slug Gunner in it's prototype stage. Although many refer as baby
    Gunner, It was officially a Slug Gunner during it's undergo experiment.
    
    Q. I heard about character penalties, is that true?
    A. Yes. Some characters such as Ralf is so powerful when he use his Vulcan
    Punch, so he's weapon stock is reduce by half.
    
    Q. Can any of the characters turn Invulnerable for some time, other than
    popping out from the Slug?
    A. None, but Clark somehow has this ability to remain Invulnerable when he
    perform his Argentina Backbreaker for at least 3 seconds while Ralf has the
    ability to return from the living from being hit once.
    
    Q. Which character do you like?
    A. I can't say. On Easy Mode, I like Fio and Marco and in Hard Mode, almost all
    the character is balance.
    
    Q. What kind of weapon do you prefer?
    A. Flame Shots. Too bad I can't use it on the final boss battle.
    
    Q. Which Slugs do you think is the coolest in Metal Slug 6?
    A. I could choose the Prototype Slug Gunner, but I like the Donkey Slug.
    Believe it.
    
    Q. ARGHH!! My weapon!! It just change to a weapon I don't like!
    A. Calm down, this happens to me once too. If you want the old weapon to stay,
    simple highlight it (or change in the weapon you want) and grab the other
    weapon. This way, the selected weapon won't be discarded.
    
    Q. I can't find anything useful about this new weapon SNK add in (Zangetsu
    sword) I think this weapon is a junk.
    A. Don't say that! Zangetsu Sword is extremely useful, especially later in the
    stage. The weapon can destroy energy shots like pistol shots or bazooka shots,
    and has the damage value of a shotgun, but hits multiple times than a single
    blast! SNK did a good job creating this weapon, so be proud of it!

         START                          -         Pause
    
    -----------------------------------------------------------------------
    5.Characters
    -----------------------------------------------------------------------
    
    Each and every last character has their unique ability and advantage. This is
    also the first time SNK elaborate these unique feature in the Metal Slug
    universe. Other than the usual team, Clark and Ralf from the Ikari Warriors
    joins in the fun.
    
    Marco Rossi
    
    Specialty: Default weapon is stronger than normal
    
    Explanation: Marco's pistol weapon has the same damage as the Heavy machine
    gun, only slower and does not consume ammo (duh!). His Pistol power can make
    major difference in the game. Balance hero with lots of problem in his head.
    Best accompany with Tarma
    
    Tarma Roving
    
    Specialty:  Double the damage done when controlling any Slug, increase armor
    and capable to activate Vulcan Fix.
    
    Explanation: Tarma has the ability to do more damage whenever he is inside the
    Metal Slug, reckless of any type. He only get average ammo at each weapon crate
    he collect. The main thing about Tarma is that he has the ability to take less
    damage whenever he is inside the Slug, more firepower and does more damage
    using the cannon option. Bring him along for a joy ride and see what I mean.
    
    Fio Germi
    
    Specialty: Double the supply and weapon crate, has Heavy Machine Gun from the
    start, pistol does less damage than normal.
    
    Explanation: Never thought Fio could be lucky to bring along a Heavy machine
    gun so early in almost every stage. She also gain double ammo whenever she
    picks up weapon crate and supply, but her Slug damage is something we shouldn't
    look forward too. In easy mode, she gain a SUPER heavy machine gun, and pack a
    lot of punches! This character is best accompany with Eri.
    
    Eri Kasamoto
    
    Specialty: Double grenade/bomb supply, can throw further/ above using the
    control pad.
    
    Explanation: Eri's a Demolition expert!! She gets double the grenade supples,
    throws further and does more damage with each throws. too bad it didn't enable
    the same strength in the Slug. Eri may deliver a short blow with her weapon
    arsenal, but let her take all the grenade in the game and let loose the
    bouncing green stick on her enemy, or to a hapless boss.
    
    Clark Steel
    
    Specialty: Does an Argentine Backbreaker stunts that gives Clark 1000 points
    and double the point at each kills, gain a momentary invulnerability while
    doing the SAB.
    
    Explanation: Clark Steel from the Ikari warriors make a tribute in Metal Slug
    6. His Argentine Backbreaker can kill almost all organic enemy with a single
    attack (except Martians and zombie, don't try it) His ability to tackle all
    infantry gives him points like crazy. His Slug however is a pushover, does less
    damage than normal. Try doing an Argentine BackBreaker stunt and watch him do a
    cool posing. Oh, did I mention he turns invulnerable for a short while when he
    does it?
    
    Ralf Jones
    
    Specialty: Does a Vulcan Punch that damage almost all ground unit. Can take two
    hits, fastest melee character in the game, enhance damage for Zangetsu sword.
    
    Explanation: Ralf, like Clark came from the same game, fight together and even
    enter the King of Fighters tournament. Ralf has an unusual ability to turn his
    fist into a short range Heavy machine gun that does TONS of damage. It kills
    tanks, Martians, Morden's men, bosses (O.O) and even the new alien that came
    straight at him dies with just a couple of hits. Ralf also has a 'second' life
    that brings him back to the living (O.O). The worst thing about Ralf is that
    his ability to use weapon crate ammo and grenade supply is limited by half! His
    best accompany with Clark Steel
    
    -----------------------------------------------------------------------
    6.Character Match-up
    -----------------------------------------------------------------------
    
    In two player mode, characters with stats are hard to understand, but matching
    them with the right partner will strengthen their rank and lower their
    disadvantage. Come up with a partner of your own, but these are recommended for
    team play.
    
    Marco and Tarma, Metal Slug Classic
    
    As the name applied, these dual heroes are the best matching team. While
    Marco's strength lies on his handgun, Tarma help his partner by using the Slug.
    In the hand of a veteran gamers, these two will last long enough to fight the
    final boss without continues and lost of life. Concentrate fire is recommended.
    
    Mission Achieve: 90%
    
    Eri and Fio, Sparrow Special
    
    Think about it, have Fio pick up all the weapon crate and let Eri pick up all
    the grenade in the game and let loose all of it in sheer destruction. These two
    country girls aren't here to play, their here to kick someone's nut. They could
    out last long enough though, but may have problems in the Final Mission stage
    when weapon and grenade are used sparingly.
    
    Mission Achieve: 85%
    
    Ralf and Clark, Ikari Warriors Classic
    
    Is it just me, or does this dual heroes here have a fair advantage over one
    another? Ralf will be useless using all the weapon in the game except Zangetsu
    sword and his Vulcan Punch does massive damage on armored units, which powers
    up Ralf attack by double. Clark however goes invulnerable whenever he uses his
    SAB and an excellent choice in Final Mission, although not many are effected by
    his attack. Have Clark handle the weapon and grenade while Ralf take control
    over the Slug. With practice, these two will survive, and perhaps bringing
    their gold medal at the next King of Fighter series.
    
    Mission Achieve: 79%-90%
    
    Marco and Fio, Lovebirds
    
    Came up this idea during Metal Slug 3 gameplay and tested on this game. This
    tag team actually covers up Fio's pistol damage using Marco's help while Fio
    provide long stream of endless supply of weaponry for covering fire on Marco's
    side. They might lose some lives once or twice though.
    
    Mission Achieve: 79%
    
    Tarma and Eri, Geek Shady and the Bomb Queen
    
    Also came up from Metal Slug 3, Tarma and Eri could rule this game if only
    there is enough weapon for both of them. Tarma may need protection from Eri
    until he gets a Slug, but both already has average damage value over one
    another. In truth, they rule the Final Mission stage, but before they reach
    Final stage, they may have to team up together once for a while.
    
    Mission Achieve: 89%
    
    -----------------------------------------------------------------------
    7.Enemies
    -----------------------------------------------------------------------
    
    In the Metal Slug game franchise, there is only one thing that stands in your
    way before you reach the boss fights, and thats soldiers, Martian and the
    likes. These enemies will give you trouble as you proceed but remember, they
    won't last long before you reach their boss, as long as you survive and
    hopefully not being killed.
    
    Grunt
    This guys a pushover; they are arm with knife and grenades, laid mines and
    launch a Chinese-like rocket, nothing more. They tend to be troublesome in
    numbers though, so don't be overwhelm by their mass number of grunt.
    
    Shield Grunt
    They aren't as agile as the grunt, but they have are armed with pistol and a
    sword.  They tend to back up other grunt to work together and their shield is
    powerful enough to stop a laser gun to pass through. Consider them as a medium
    grunt that has a low melee speed.
    
    Bazooka Grunt
    Same as shield grunt, but they have enough firepower and loading time to react
    depends on your action.
    Bazooka Grunt is a major threat in numbers, but a pushover as a lone wolf. Have
    them killed first before attacking the other lesser grunt. This one is consider
    high priority.
    
    Rifle Grunt
    This Grunt is your average, fully train grunt with a bolt rifle in hand. They
    sometimes take cover from tanks, gaps and even perform a melee hit for close
    counters. In numbers, they are life threating enemies.
    
    Mortar Grunt
    This grunt, like any other lesser grunt aren't so powerful alone, but with a
    few and accompany by shield, bazooka and normal grunt masses together is a real
    threat. They trade their mobility and defense for range and power.
    
    Heavy Grunt
    Appears just after the final stage, they are slow to react and pretty stupid as
    well, but they wield out lots of bullets in a single burst.
    
    Missile Tank (without spikes)
    This armored units once have it's spikes on, for some reason they ran out of
    spikes. They still fire a slow, homing missile that homes into you. This
    armored unit is weak, so simple apply a handgun will do.
    
    Tower Tank
    The Tower tank is much like a tank with two-stories high and fires a slow
    moving cannon ball. This tank is useless, but dangerous when grouped together
    with random enemies.
    
    Light Tank
    A gray tank that serve it's purpose to simple annoy you. They have a decent
    firepower and armor, but their cannon is very slow. Counter it with a hailstorm
    of bullets or a couple of grenade.
    
    Medium Tank
    This brownish tank has better armor, fires fireballs, and very, very slow
    firing time. This armored unit seldom has grunts and bazooka grunts together.
    
    MLRS Tank
    This vehicles fires extremely heavy projectile missile and bettered armored,
    but aren't so great while on the move. This unit is toast when a character is
    near this vehicle.
    
    Combat Copter a.k.a. Little bird
    Morden's own air support. This little copter takes time to fire their weapon,
    but they intend to confuse players whenever it fires at random or horizontally.
    This can be taken out just enough bullets stuck in their hole.
    
    Apache
    This is a oversize combat copter and does the bombing run as you go. It also
    uses a projectile rockets that homes in to you. Take it out and you'll be fine
    
    Combat Jeep (With mounted Machine gun)
    A conventional Jeep that had been modified to attack and ram any opponent or
    hostel enemy. They're speedy and has decent armor, but their attack and moves
    are predictable.
    
    Villager
    These villagers somehow inherit Ralf's ability to survive after being shot.
    They aren't as tough, but in numbers, they can slice you for all they care.
    Take them out by afar, or simple let Ralf and Clark do their things.
    
    Flying Piranha
    The least enemy you would expect to see again from Metal Slug 3 is the flying
    menace itself, the flying piranha. They are weak and easily dealed with, only
    an idiot would simple ignore them.
    
    Martian
    This octopus-like creature with a gun is the Martian. They made a tribute in
    both Metal Slug 2 and 3. They sometimes attack with yellow homing goo that can
    be destroyed with a single shot. They also fires blue, speedy projectile,
    enough speed to kill you. They are your average opponent.
    
    UFO
    The flying little plate that homes in on you is known as a UFO. This pesky unit
    can kill you with their laser and has a decent defense against firearm. This
    thing tends to go out hunting you in numbers.
    
    Unknown Alien
    This humanoid is the main enemy from the entire Metal Slug 6 series. Their head
    is bigger than average human and like to eat fresh Martians. They can puke out
    worms that self-destruct, attack you from afar and do a bouncing/rolling
    attack. They even explode into chucks of worms in the final stage. Consider
    them as Martians on steroids
    
    Parasite
    Red, flying unknown alien here is what we known as a parasite. These things can
    kill your character no matter how resistant they are. They can also control
    civilian and turn them into mindless zombies. Luckily, you can only kill the
    host and won't take more than three shots.
    
    Flying Unknown Alien
    These things are the same as the first Unknown Alien, except that it grows
    wings to take flight and puke out small, slow energy ball.
    
    Eye Alien
    An alien, who has only one eye to look at you, puking some bubble that is
    harmful to your health. They have better armor and quite dangerous, even when
    they are alone fighting you. They are lethal whenever they are grouped together
    with other alien breed.
    
    Spider Alien Tank
    This four-legged creep is like a tank that can't crush you. It does two things.
    One, It fires a two plasma artillery energy ball towards you. And if you fight
    from afar, this thing will fire out a Drop Shot version. They have the same
    defense as a Medium Tank has.
    
    Unknown Mini-UFO
    Unknown driving a UFO, the same as the Martian did. But compare to Martian,
    their craft are weaker than you could imagine. It fires many energy shots
    though.
    
    Alien Craft a.k.a. Unidentified Energy Object
    Instead of a UFO, we have a UEO! This ship gathers meteors, spare parts, junks
    and fish (That's right, fish!) as a weapon and toss it one by one or all
    together to you. They have better armor than Unknown Mini- UFO and sometimes
    fires volley of hot needles. Consider the Little birds.
    
    Pulverizes
    Can't come up a good name for this red-orange alien in the final stage. This
    alien is slow, but it can fly by and forming it's leg and propel it like a
    helicopter. Once on sight, it drops like a rock, effectively killing you. They
    appears to be social-like aliens, and aren't too happy to see you.
    
    Deflectors
    Green, oversize alien-like tank that fires small beam ball with slow speed at
    random height. They are annoying enemies and tend to attack you from both
    sides. They also project a huge laser beam that rotates slowly to you and
    absorb anything you shot at. They have better armor than their Spider Alien
    Tank.
    
    Alien Ant
    This Alien appears underground when you dig your way downward. They are
    annoying and has a average armor. But they can get serious when they are near
    you.
    
    Red Unknown Alien
    These are an 'elite' type of Unknown you'll encounter in Final Stage. they are
    better armored and handgun has little effect to simple ignore them. Fire as
    fast as you can by killing them with Shotgun, Zangetsu sword, Laser or Duel
    Machine Gun. Killing them before they attack will wield out normal points, try
    your best to kill them whenever they attack you, which wield out 10000 Points!
    
    Mother Eye
    Huge, freaking Eye Alien's mama. They are invulnerable to all weapons on their
    bodies, but no defense on their eyes. This thing kept on firing seeds of doom
    to you and sometimes accompanied by the unknown alien. They can take a lot of
    punishment before going down.

    8.Weapons
    -----------------------------------------------------------------------
    
    The saying ' your weapon is your best friend ' is best descript as something
    you shouldn't done in real life. The saying ' we only fire when fired upon ' is
    also not true in this game. So, let see what our old armory has and try to hit
    something with it on Morden's men, Martian and the likes. SNK did a good job
    building a new system as well, so carrying two weapons along with your everyday
    handgun is unique. Each weapon will be discard if you ran out of ammunition or
    if you picked up a newer weapon. So remember, guns don't kill people, we do.
    
    Pistol/ Magnum
    Damage value: *
    
    Your bread-and-butter weapon of choice. Has infinite ammo and does half the
    damage done by a Heavy Machine Gun. This weapon can be used almost all
    situation, from fighting against horde of men to boss battle.
    
    Heavy Machine Gun
    Damage Value: **
    
    This weapon has been in this game for over 10 years, and it is still the
    balance weapon used. Heavy Machine Gun does twice the damage done by a Pistol
    and can fire almost all directions. The main floss is that it consumes a lot of
    ammo just by a single bust. This weapon is all-purpose type arsenal.
    
    Rocket Launcher
    Damage Value: ***
    
    The weapon used to clear mass numbers of infantry and armored tanks. Does a
    splash damage as well. This weapon has very little homing device, but packs it
    all into speed and raw power. Use at your own risk, as it has a major cool down
    at each two shots it fires.
    
    Flame Shot
    Damage Value: *****
    
    Your typical Flamethrower on steroids, this weapon can incinerated almost
    anything, and can be used to cook your foes to crispy perfection as well.
    Devastating damage, but it's short range gives a little weapon less effective
    against opponent that had you pin down. Use this weapon during an emergency
    only, or simple torch the entire army with it.
    
    Shotgun
    Damage Value: ****
    
    The same weapon as the Flame Shot, but no splash damage, just an impact sound
    of bone crashing and bodies flung from one side to another. This weapon can be
    your friend AND foe. In short, this is a great weapon to clear unwanted path
    and get rid of the entire enemy in front of you. It also takes at least 3
    second cool down at each shots, making it difficult to use when both front and
    back screen starts to overflow by enemy.
    
    Laser Gun
    Damage Value: ***
    
    An enhanced version of Heavy Machine Gun. It's raw power can cut through
    anything it touches, and destroys armored units like a breeze. This weapon has
    floss though, like the machine gun it consume it's ammo like mad, bursting out
    4-5 ammo straight. Unlike the machine gun, it also takes a lot of time to kill
    the shield grunt, even though this weapon can cut through armored units like
    cutting butter with a burning chainsaw. Keep this weapon for last, as this
    weapon is an ideal arsenal against bosses.
    
    Drop Shot
    Damage Value: ***
    
    The bouncing bomb that... er bounce on the ground. This weapon is perhaps the
    oddest weapon created by SNK. Like it's sidekick Iron Lizard, this weapon is
    not always good against ground units, but it has a small splash damage. It also
    bounce towards the enemy before it hit something or explode on it's own. Like
    the Rocket Launcher, it has a major cool down after three Drop Shot is fired.
    
    Iron Lizard
    Damage Value: ***
    
    This weapon is an anti-ground weapon used to target infantries, tanks,
    Martians, and the likes, massive splash damage that hit even at the far rear of
    a battalion. For a weapon that hit almost all ground units, it also can be used
    to shoot up as an emergency.  It's fast and lethal, and an ideal weapon against
    mass number of foes.
    
    Enemy Chaser
    Damage Value: **
    
    This is like Rocket Launcher on steroids, it's fast, no cool down, little
    splash damage, random targeting sensor and absolutely ridiculous damage value.
    This weapon trade of it's damage to homing capability, which it zero in towards
    the enemy. This weapon can also be used to find and locate hidden prisoner or
    hidden items. Not an ideal weapon against boss.
    
    Super Grenade
    Damage Value: *****
    
    Super Grenade is like a pump up version of the standard grenade that shoots
    straight. It's massive power over armored tanks are something to believe at. No
    vehicles can withstand it's raw power not more than two hits. This weapon is so
    devastating that it only has 20 ammo or so, enough to send soldiers flying from
    one end to another, destroys uninsured enemy armored tanks and boss battle turn
    short as it constantly being hit by it.
    
    Dual Machine Gun
    Damage Value: ****
    
    Heavy Machine Gun's greater cousin. This weapon is the powerhouse version of
    Heavy Machine Gun, doubles the ammo capacity and feared by many. Like its
    lesser cousin, it is also ammo consumer, up to 8 ammo! Unlike it's lesser
    cousin though, it can't fire all the direction you want. Use this weapon on
    heated battle and boss fights.
    
    BIG Heavy Machine Gun
    Damage Value: ***
    
    A beefup version of Heavy Machine Gun. It's better powered and improve damage,
    but like it's previous incantations, this weapon still has a few floss. This
    weapon is rare and available in Mission 4-2, Slug path.
    
    BIG Rocket Launcher
    Damage Value: ****
    
    A beefup version of Rocket Launcher. It fires a gigantic missile that can
    damage anything before and after impact. It's large splash damage is awesome,
    but like it's incantation, this weapon still has a few floss. This weapon is
    rare and available in Final Mission
    
    BIG Shotgun
    Damage Value: *****
    
    A beefup Version of Shotgun. This weapon is so powerful that it can take out
    almost anything in front. Massive damage and included a splash damage, but it's
    ammo useage is something to be believe at. Like it's incantation, this weapon
    still has a few floss. A rare item found in Final Mission
    
    BIG Laser Gun
    Damage Value: *****
    
    A beefup Version of Laser Gun, or perhaps the most powerful weapon found. This
    is so powerful that it can take out Red Unknown Alien faster than Duel Machine
    gun could. It's power over mechanical unit is also an unbelieveable. This rare
    weapon is found in Mission 4-2, Slug path but like before, the BIG Laser Gun
    has a few floss similar to the normal Laser Gun.
    
    Zangetsu sword
    Damage Value: ****
    
    For some reason SNK wanted to use this arsenal as a weapon of mass destruction.
    Well, we read ya SNK for this weapon happens to be as useful as it looks later
    in the stage. This weapon has the same damage as the Shotgun blast, only it
    deals multiply damage than a single blast. Use this weapon against armored unit
    and cut it to tiny scrap metal is nice, but having a limited range means you
    need to get near it and only attack vertically. Capable to block energy shots
    and when the meter goes max, Zangetsu sword will unleash wave after wave of
    coins on enemy vehicle with each strike. Absolutely NOT an ideal weapon against
    boss, but an excellent weapon on the mid-boss battle.
    
    -----------------------------------------------------------------------
    9.Grenades
    -----------------------------------------------------------------------
    
    In the Metal Slug series, grenades are your friend whenever you need to clear a
    certain path or just to lower the boss down. This bounding green stick will
    help you out, and will always replenish each stage. Or in other case, if you
    die. SNK provide only 2 types of grenade from the original Metal Slug and Metal
    Slug 2, namely Grenade and Firebomb
    
    Grenade
    Damage Value: ****
    
    This is your typical grenade with awesome power. It has a massive splash
    damage, bounds a couple of times and powerful enough to kill anything most
    average armored units appears in front of you. This is your most used weapon
    and perhaps an ideal weapon against bosses.
    
    Firebomb
    Damage Value: *****
    
    This weapon was introduce in Metal Slug 2 and boy, does it come hot. Although
    this weapon doesn't bounds (this weapon is made out of glass, so basically it
    can't bound) but if the weapon is hit by solid ground, it will create a
    momentary firestorm, perfectly to kill (or burn) any unit that is foolishly
    jump in it. This weapon also has a awesome splash damage and easily the most
    useful weapon by fan demands.
    
    -----------------------------------------------------------------------
    10.Vehicles(Slugs)
    -----------------------------------------------------------------------
    
    Vehicles are not an essential to the game, but it's a what their here for.
    Metal Slug and the rest of the armored unit are there for the heroes to ride
    in, giving a major boost on defense, firepower and raw power. Some of these
    vehicles are available during the boss fight and some do not. Here's some of it;
    
    Metal Slug
    
    The original Super Vehicle 001 a.k.a Metal Slug still makes a tribute in the
    game. These things serve as the backbone for the entire game, since it's the
    only vehicles named after a slug (huh?) in the first series. The Metal Slug has
    360 degree firing angle, a powerful cannon and an average speed, nice defense
    and easily the best vehicles in the past 10 years.
    
    Donkey Slug (With Cannon Convoy)
    
    Okay, whose idea was it to have a donkey-mounted Vulcan? This thing is so slow;
    it compares the Elephant Slug on a low perspective. Like the Elephant Slug,
    this unit is slow moving and exposing you. One unlucky hit and bam! there goes
    your life. Good thing is that the Donkey Slug has a VERY powerful 360 degree
    Vulcan equipped, thank god! Did you know that when you use a frontal attack,
    the convoy wield out coins upon destruction?
    
    Slug Gunner (Prototype)
    
    Believe it or not, this vehicle found in Mission 3 under the sewer is actually
    the prototype of our once powerful Slug Gunner. Even when this vehicle is still
    a prototype, it can move faster and jump higher than the Gunner could, 180
    firing degree angle and has a build in Vulcan Fix, but having a hero expose is
    something bad though. It also hate to turn, taking it's time turning to the
    right direction. Weaker than it's fully completed one, but pack with surprising
    moment. Who would have wondered the Slug Gunner was so useful even in its
    prototype stage?
    
    Slug Flyer
    
    The classic Slug fighter and it haven't even change a bit. It has a 90-degree
    firing angle and a cool all-purpose missile. Like the Metal Slug, this vehicle
    is not entirely invulnerable. It does however hover depending your movement on
    you control pad. It's frontal attack is much powerful though, think of it as a
    kamikaze vehicle with steroids in it. This Slug can't attack at it's rear end
    however.
    
    Drill Slug
    Do not be confuse by the Slug Driller, this Slug main function is to dig it's
    way underground. Seeing that this vehicle is good, it has it's floss. One, the
    drill does no damage on enemy and two, the grenade it launches are hard to
    control. With practice, this Slug could be your friend. Try and used it to find
    a treasure next time.
    
    Super Metal Slug
    
    No, this Metal Slug can't fly nor it is invulnerable. Super Metal Slug appears
    red or orange in color and has a very powerful Vulcan, firing cannon with
    forceful blast and jump higher as well, minus the recoil. Just imagine that
    this Metal Slug hasn't been given a good treatment lately and had lotsa
    steroids on it. Found in the final stage.
    
    -----------------------------------------------------------------------
    11.Tips on Beat-the-crap-out-of-Metal Slug 6
    -----------------------------------------------------------------------
    
    1. Know your enemy. While many people know the Rebel and Martian attack tactic,
    many player, newbie and veteran alike always let themselves been killed. Avoid
    this from happening at all times
    
    2.Note that SNK is generously gives players the ability to set up high score by
    killing and filling the lower meter full for extra points.
    
    3.Some weapons, such as Duel Machine Gun or Flame Shot are rare, so don't waste
    it on normal foes, keep that weapon until you absolutely need it.
    
    4.The Metal Slug glitch is still there, but majority of us forget about it and
    even complain about it. For those who is new, simple press down on the control
    pad and jump button. The Slug will take no damaged during this act and the
    character you control remain invulnerable until he lands.
    
    5.Check the map location throughly, you may need to recall if there is a hidden
    item or prisoner in the area.
    
    6.Zangetsu Sword is perhaps your only weapon used against Mid-boss battle in
    the Final Mission. Keep as many as you can, as it's damage value is well earn
    to those who keep it.
    
    -----------------------------------------------------------------------
    12.Walkthrough
    -----------------------------------------------------------------------
    
    Complete walkthrough and with no hidden prisoner been reveal, it covers a lot
    of stages and boss fights. This game is played on HARD difficulties and yes, it
    covers final mission as well. Also, I will try and cover the character's tactic
    and advantage on the walkthrough. For hidden prisoners, please refer to
    Prisoner Location below this FAQ. (Under Construction)
    
    =================================================
    Mission 1
    Difficulties: Walk in the Park
    Character Advantage: The Lot.
    Character Disadvantage: None
    =================================================
    
    Ahhh, The Metal Slug Theme song for MS6 is back and better. You arrive on a
    rural area where you will be spotted by a grunt as you move forward, attack the
    grunt and more will come. A Prisoner there will give you your first weapon,
    Heavy Machine gun. Move forward and you'll arrive at the enemy outpost. This is
    where the fun begins. Shoot anything non friendlies and a truck loaded with
    grunt will join the fun. Attack the truck to free the prisoner inside, giving
    you a Rocket Launcher. Use it and cause some mayhem on the shield grunt. There
    are two crate as well, bomb supply and an Enemy Chaser. Pick both up, as more
    grunt and armored vehicles will join the fun. Once you clear the mess, move
    forward until the tower armored vehicles appears. Use your pure classic attack
    on this vehicles. Oh, remember to retaliate the grunt at the back as well. Move
    forward until you reach the river, saving another hostage and fight more grunt,
    mortar grunt, and shield grunt. An Apache will greet you at the river, giving
    you presents that you refuse to take. Take it out for a love letter it gives
    you. Move forward, rescuing 2 more prisoner, killing grunt and 1 more prisoner
    that has a Heavy Machine Gun. By the time you have equipped that weapon, a
    Morden's Centipede Convoy will appear, moving from one screen to the other. Try
    and destroy all of the segments and free the Metal Slug while your at it. If
    you destroy all of the segments, coins will wield out. LOTSA coins!
    
    Marco and Tarma: Coins For All!
    Fio and Eri: Shopping Spree!!
    Ralf, looking at Clark: Why are we hooking up with these guys again?
    
    Move forward and you'll be arriving at a cliff side. Kill more grunt and save
    another prisoner, this time he wield out an Iron Lizard. Use the Slug or Iron
    Lizard and fight off the grunt. Right now, you should have to fight a combat
    copter with no problem at all, rescue another prisoner for a Heavy Machine Gun.
    After the area is secured, you have a choice to go up or move forward. The
    choice is your.
    
    Route A
    
    Marco: Forward, march!
    Ralf and Tarma: On it!
    
    Moving forward. There you will be block by a huge gate. Destroy the gate and
    kill the bats as well. You will spot a prisoner been eaten alive by a bunch of
    bats with a Mortar grunt and a single tank guarding the area. Kill it and
    rescue that Prisoner. This prisoner wield out what you've been waiting for. A
    Flame Shot! Move forward and there will be another three more prisoners ahead.
    When you rescue them, the grunt will appear, attacking you with all the
    strength they have. Waste them using the Metal Slug or invite them for a
    barbecue festival using the Flame Shot. I recommend you save the Flame Shot for
    last though. Once all the grunt lay down and disappears, move forward until you
    see a prisoner and a lone tank guarding the area. Waste that tank and destroy
    the gate, enters your first boss battle
    
    Route B
    
    Tarma, driving the Metal Slug: Who's idea was it to take the high road!?
    Fio and Eri: Get out from the Slug then!
    
    Jump up according to the ledges. This isn't pretty, as shield grunt, bazooka
    grunt and normal grunt cornered you. Your Slug might be hit once or twice, so
    be sure to kill the bazooka grunt first, normal grunt and finally shield grunt.
    Work your way up until you see four prisoners hold up just at the peak.
    Carefully release them and rescue all of them. One of them has a Heavy Machine
    Gun crate (Re-joys!). When you rescue these prisoners, an armored vehicle
    appears and starts to attack you. Retaliate it and move forward where several
    parachute bazooka grunt and combat copter appear, giving another opportunity to
    kill you. When the entire enemy does their free fall, continue going up until
    you reach the summit, move forward until you reach the entrance.
    
    You will perform a free fall here, scaring the shit out of the two grunts.
    Shoot anything that worth the points, including bats, and more prisoners. There
    is also a Gas tank, boosting your weary Metal Slug and a wonderful weapon
    crate, Super Grenade! When you approach the weapon crate, more grunts and tanks
    will come inviting you to their prison. Simple say no and kill everything non
    friendlies. Move forward to you first boss battle.
    
    Marco: Hey, that boss looks familiar...
    Tarma: OhmygoditsourSlugDriller!
    Other characters: Pardon?
    
    =======================================================================
    BOSS BATTLE ONE
    MASTER DRILLER
    
    Suitable Weapon: Heavy Machine Gun, Super Grenade, Flame Shot, Rocket Launcher.
    
    Is it just me, or is this some sort of joke? This boss isn't worth your penny,
    but they make havoc on the surface, might as well destroy it. Morden must have
    come up with this from the Slug Driller. No matter. Time to stop this machine
    once and for all!!
    
    1st Form attack: Raise shield up, releasing some sort of Iron Lizard.
    Destroying it will wield out random weapon crate, bomb supply. Long range
    artillery blast, fires gigantic Stones from their machine's upper hole.
    
    2nd Form attack: Fires gigantic Stones from their machine's upper hole, Massive
    Driller that sometimes fires out it's drill, similar to Drill Cannon from the
    Slug Driller.
    
    This is ridiculous, Morden copy everything the Metal Slug team once has! This
    boss has an Iron Lizard, Stone and even the Drill cannon! His first form is as
    weak as hell, just fire volley after volley of firepower is enough. Watch out
    for their intimidating Iron Lizard though. When a grunt pop out on to of the
    shield, get yourself some covering ground! After you destroy the shield, a huge
    oversize drill will appear and remember to stay away from it, as it sometimes
    starts to drill when you approach it. It also splits out Stones from above,
    thank goodness it's slow though, and evading it is easy. However, don't leave
    the stone where it is, as the Master Driller will use its Drill Cannon. If you
    still have the Metal Slug, simple attack with your eyes close (No, seriously.
    ATTACK with your eyes close.) and watch the monster go down in less than a
    minute. Mission 1 Complete!
    
    Results from the characters;
    Marco: Easy as pie.
    Tarma: Owned once I got the Slug.
    Eri: Pushover, where's my remaining grenade?
    Fio: Geez, I still have ammo left.
    Clark: That thing is heavy too lift, but got it down.
    Ralf: Vulcan Punch anyone?
    =======================================================================
    Total number of prisoner found: 25
    =======================================================================
    
    =======================================================================
    Mission 2
    Difficulties: Boot Camp, Office work.
    Character Advantage: Ralf, Clark, Marco, Eri, Fio.
    Character Disadvantage: Tarma, Clark and Ralf (second phase and boss fights)
    =======================================================================
    
    Wow, this mission theme song is the remix from the first Metal Slug game,
    mission 2. You arrive what appears to be a village ruled by Morden's men and
    its villagers aided them. When you land, a single villager will greet you with
    his kitchen knife with his partner down at the dock with a dynamite. Put him
    down and his friend and rescue your first prisoner. Move forward and you'll see
    your next prisoner, but the villager wanted him too. Kill them and even more
    villager came along, joining the fun. Move forward and get the Laser gun below
    deck, with a ammo crate from the one of the two prisoner ahead. Kill the
    villager first before going towards the MLRS tank. Dispose it and move forward
    for your next prisoner, who happens to have a firebomb. Waste the flying
    piranha and a couple of villager, move forward and get another laser and ammo
    crate.
    
    Tarma: Is it just me, or did I just saw a UFO?
    Marco, Eri and Fio: de' javu?
    
    When you reach the end of the screen, destroy the gate to proceed, but the
    villager wouldn't let you, so try and survive the onslaught before tackling the
    gate.
    
    Ralf: This is where I'll show my technique to EVERYONE! Vulcan Punch!!
    Fio: Eat Laser creep!
    Eri: Barbecue anyone?
    Tarma and Marco: Me, me!!
    Clark: One little, two little, three little rag doll (Does an Argentine
    Backbreaker all the way)
    
    Once you pass the gate, you'll approach a single prisoner, wielding a Drop
    Shot, and the 2 Martian came down greeting the Metal Slug team.
    
    Clark: On my God, Martians! We're under attack!
    Martians: Hello earthling, we come in peace.
    Marco: Oh, thatís good then, so no...fighting? (sees Clark pull out a knife and
    kill both of them)
    Ralf: Friends of yours?
    Tarma: We're so dead.
    
    Yes, dead as ever, more forward and free another prisoner, wielding out a Flame
    Shot. Roast the Martians that appear both front and back screen before moving
    on. There you will see a Donkey Slug with a grunt appears to try to steal it.
    
    Fio: Who the hell send in the Donkey?
    Marco: I was told there were sending the Metal Slug, but they had to abandon
    that request.
    Eri: Why?
    Marco: HQ saids a Donkey will do fine, which they did.
    Tarma, riding the Donkey Slug: It's slower than a god damn Elephant Slug!! I
    want my money back!!
    
    Yes again, a donkey, equipped with a Vulcan, a VERY powerful Vulcan. Use it and
    travel forward, and more UFO came down, raining laser at you. Deal with it and
    it will go away. Don't forget the prisoner too. As you move forward, you might
    spot the cannon convoy, as you will arrive what seems to be a very small
    outpost, with the grunt looking for an intruder. Greet him with the Vulcan and
    enter the outpost, having the convoy attach to the donkey. There is Rocket
    Launcher in the crate and two prisoners, one of them will give you a new
    weapon, the Zangetsu Sword
    
    Fio: Sonic What?
    
    In no time, the bazooka grunt from both sides will appear, followed by a flood
    of grunts, armored tanks and Martians. Try to survive it and move forward. A
    single prisoner, Hyakutaro will help you as you progress the next segment of
    the outpost. You'll spot four prisoner, one of them has a bomb supply which is
    good for either the donkey or Eri. As you move on, more grunt and bazooka grunt
    will attack you. Be warn though as the grunt is now seriously want you dead,
    pulling out their knife to kill you. As you fight on, Martians and UFO joins
    the fight, followed by more bazooka grunt, medium tanks, Martians and UFO, a
    wonderful display of violent and explosion all into one screen.
    
    Clark: It's like World War 2 already!
    Marco: Hey, we eat this kind of things for breakfast.
    
    After all that, the door is good for the taking, you can use the frontal attack
    to destroy the convoy, wielding out precious coins all the way for your trouble.
    
    Tarma: No!! My donkey!! Yes!! Money!!
    
    Or simple attack the gate with full force. Either way, the donkey stays behind
    for your second boss fight.
    
    Tarma: No!! My Donkey!! I Want My Donkey!!
    Eri: Get this guy a pony.
    
    =======================================================================
    BOSS BATTLE TWO
    MONORAIL TANK
    
    Suitable weapon: Laser Gun, Heavy Machine Gun, Flame Shot, Rocket Launcher
    
    The tank that went out of control, speeding down the hill exceeding our laws
    speed limit and the entire team have to destroys in on it's lower deck. To make
    matters worse, this boss even wield out lots of rockets traveling vertically at
    random location. Try your best to fire the huge turret and evade/destroy the
    missile.
    
    1st Form Attack: Launches a hell lot of rockets, launches tomahawk missiles,
    side turrets.
    
    2nd Form Attack: Flak attack, Gigantic Missile attack.
    
    Here's the rules, the 1st form is a monster, it will launches multiple rockets
    that goes vertically from one screen to the next, launches it's tomahawk
    missile at you and pulling out it's side turret. These attacks appear to be
    random. When you see that if it starts to launch multiply attack at once, that
    means it's close to it's death. Attack the Giant turret and defend yourself
    from all the threat it uses. And remember, Heavy Machine gun is your friend
    here. Flame Shot also helps very down this tank, including the laser gun. Just
    as the 1st form is destroyed, get ready for the lord of pain. The upper turret
    slides back and reveal a giant missile silo, launching towards the sky with
    it's flak. Unfortunately, the missile appears to be heavy and starts to fall
    down to earth! Evade the missile's attack and destroy the missile silo. Fire
    bomb works well here, waste it all onto this boss. Then, when the screen
    appears to be zooming out for a long time, get ready to run, evade and gun
    tactics, as the missile will continue to launch, firing flak out and launch
    again. This also means that the boss is near death. Finishing it and celebrate
    your victory after it crash down hill. And watch the cinematic too. Mission 2
    Complete!

    country folks. When you land, you spotted Rumi Aikawa. Shoot her bag and try to
    get her in you rescue list. you'll be greet by this new alien and aren't too
    happy to see you. They will puke out worms ( Fio shriek: GROSS!!!) attack you
    from afar by extending its arm and roll towards you or even do a Sonic Spin
    from the famous Sonic the Hedgehog. Move forward and get the prisoner. Deal
    with these alien some more until you see two crates, wielding out a Heavy
    Machine Gun and a Shotgun. Keep the shotgun and waste the Heavy Machine gun
    against the alien. More prisoners along the way and more aliens still having a
    'rolling' good time. As you reach to flat land, a prisoner will give you yet
    another Zangetsu Sword. After you receive it, a jeep mounted with a machine gun
    will appear to ram you.
    
    Clark: What's your problem man?
    Marco: Maybe it's the deliveryman I asked.
    
    Avoid it and use your new weapon against it. Two more jeep will appear to kill
    you. Finish them and switch to your Shotgun, climb up the bamboo and fight more
    alien, more crate and more prisoners awaits. As you move forward, remember to
    arm yourself with grenade crate from the lower floor. You will have to jump
    down and intercept the alien and rescue two prisoner below. Go down again with
    the prisoner wielding out a bone for your trouble(!). When you reach another
    lower floor, the alien will attack you using their rolling attack. Kill them
    and more will come from the back. Go down for the last time and grab both Drop
    Shot and Iron Lizard. Move forward and saw hello to your new tank-like alien.
    
    Ralf: What the hell is that?
    Eri: Intel never saw anything about this!
    Marco: Screwed the Intel, lets trash it!
    
    Sure enough, this thing can shoot out plasma goo and even a similar Drop Shot
    attack. Destroy it and another from the back will appear, pulling the same
    tricks as the first one did. After the second one is down, go forward and the
    alien drop on to your position. Killing or ignore it is up to you. From here
    you will reach two-way points, go up the stairs or down the maintenance chamber.
    
    Route A
    
    Marco: I smell Chinese noodle from up there, lets go!
    Fio, Tarma and Eri: Stop thinking about your stomach Marco!
    
    Go up the stairs and you'll arrive at what appears to be Chinatown, trashed by
    the aliens. When you move on, you'll see a red floating alien known as the
    parasite. If you leave it alone, it will attack you or convert the civilian
    into...
    
    Fio: Oh my god! They suck their brain!
    Tarma: Oh my god! Their Zombies!
    Eri: Oh my god! They pulled out a grenade!
    Marco simple knife it down: Oh my god! Their weak as hell!
    
    Yes, these things can't even that two shots from your pistol, but be careful
    not to get caught though. Move along and you'll see a prisoner, offering a
    Flame Shot for free. Waste this weapon on the aliens and watch it dance for
    their lives. As you continue forward killing the parasite and alien, you'll see
    several man with a chicken in hand, trying to knife it down. Simple shot at his
    location to make him drop the chicken. Get the firebomb and shotgun as well.
    Almost immediately, more and more parasite will appear, either controlling the
    mans brain or attacking you. Deal the final alien and enter a new location.
    
    Ralf: Aliens, check. Parasite, check. What did I miss?
    Clark: Sewers, does that count?
    
    Sewers it is. Somehow, the alien find it comfortable here until you show up.
    They wanted to show you the door, but you rather want to stay, right? Move
    forward and attack anything not human. There are several prisoners that wield
    out good items and weapons, such as Drop Shots. As the alien fight back, the
    alien-like tank appears, attacking you with it's typical plasma goo and it's
    very own Drop shot. Show them what a real Drop Shot looks like and move
    forward, another prisoner awaits, guarded by several aliens along the way. Pull
    out a firebomb to finish it. Move forward and deal these bouncing alien again
    with the firebomb, roasting them very good. Then, move forward into the
    maintenance's chamber with two prisoner pleading for help, which wield out Dual
    Machine Gun and an ammo crate. Save the Dual Machine Gun and concentrate fire
    at the alien, it appears from the front and the back screen. A Prisoner will be
    drop off with another ammo crate, use this crate on the Duel Machine Gun and
    prepare for some serious bouncing action. The alien appears to be pissed off
    and launch a full 'bouncing' attack on you. This is where the Dual Machine Gun
    comes useful. Fire wildly at them using the Dual machine gun and you'll be
    fine. Throw some firebomb or grenade if you're in some tight situation.
    
    Tarma: Intel NEVER said they were this many!!
    Fio: My arms are killing me!!!
    Ralf, doing his Vulcan Punch: Keep them away!! NO, Stay Back!!
    
    After the bouncing alien finally been put down, keep going down and two more
    alien tries to defend themselves by puking worms, again.
    
    Fio: DIE YOU ALIEN SCUM!!!
    Eri: You know, I never seen her like this before.
    
    There will be two crates along the way, both wield out a Rocket Launcher and
    Zangetsu Sword. As you move on, an alien ship known as UEO appears out of
    nowhere, lifting the rubbish, and fish as weapon. Wait, did I mention fish?
    Simple destroy the machine and it'll be down in no time. Do watch out from the
    alien that appears from the back. As the last enemy is destroyed, you'll get a
    cool surprise, the Prototype Slug Gunner
    
    Clark: What the hell is this?
    Ralf: Looks like some sort of Slug...
    Tarma: It's the prototype model for the future fighting machine.
    Marco: HQ send it out to test it's capability before it is manufactured.
    Tarma: With no protection on it?
    
    Use the new Slug and get ready to fight the boss.
    
    Route B
    
    Fio: I heard something down there.
    Eri: let's go then.
    
    Move the control pad down and crawl down to enter the maintenance chamber. Here
    you'll be greet with the red floating alien known as the parasite, and with no
    civilian around except you, it will try and zoom onto you, sapping you dry.
    Fight your way and rescue several prisoners along the way. Some of them will
    give you weapon, such as the famous Rocket Launcher and Heavy Machine Gun. When
    head to the middle of the stage, alien and parasite came swarming the area, try
    to fight off and survive the attack. When the attack died out, move forward and
    two alien-like tanks appears from both ends with more alien and parasite
    warping together. Fight your way to the next area. You'll appear what seems to
    be a maintenance area with a prisoner awaits. Kill the two alien and rescue
    another prisoner, wielding out a Zangetsu Sword with a Rocket Launcher inside
    the crate. Move forward and alien ship known as the UEO appears out of nowhere,
    lifting the rubbish, and fish as weapon. Wait, did I mention fish? Simple
    destroy the machine and it'll be down in no time. Do watch out from the alien
    that appears from the back. As the last enemy is destroyed, you'll get a cool
    surprise, the Prototype Slug Gunner. Use the new Slug and get ready to fight

    Marco : Your not the only one.
    
    =======================================================================
    BOSS BATTLE THREE
    ABOMINATION
    
    Suitable Weapon: Dual Machine Gun.
    
    This is perhaps the eeriest boss battle I've ever seen. It has it's brain and
    eyeball on the goldfish bowl there, sharp claws and a small... dick. Thatís
    right. A dick. This is also one of the most long endurable boss you'll fight,
    so get that Slug ready, your going to need it
    
    1st Form Attack: Vehicle toss, plasma balls, shock wave, claw attack, ribbon
    beam.
    
    2nd Form Attack: Goes berserk, multiple plasma balls, longer claw attack,
    ribbon beam, vehicle toss
    
    Don't get near that boss. Seriously, don't get near it. Ralf will be completely
    useless here, so let him get all the duel machine gun or let him ride the Slug.
    Clark can use the Duel Machine Gun well and Tarma can do even without the Slug.
    This boss is a hard nut to crack, your best choice is to attack, move and jump,
    repeat. Use this strategy on the plasma balls. When you see a box appears at
    the back of you, jump on it and wait for the following;
    
    1. If it opens a center hatch, prepare to evade its ribbon beam. Characters not
    riding the Slug will have to predict where the beam is arching, either up or
    down and find the gap for cover. Character on the Slug has to be wise not to be
    hit by the beam. Have the beam goes across the Slugs leg so that the character
    won't be hit by it.
    
    2. It will launch Shock wave, an attack that will kill anyone who isn't above
    the box.
    
    3. It will kneel down and pull out a... vehicle out of nowhere and toss it to
    you. Where did that vehicle came from?
    
    Out of the three attack list, it will keep on launching it's plasma balls
    towards you. So be careful. It will go berserk if you keep on damaging it or
    pissed it off by moving too near, jump back and attack it while it goes it's
    claw attacks. When you see it's brain starts to change color from yellowish to
    near red and sparks like mad, that means it's going to die. Dual machine gun
    can be found each time it does a ribbon attack or vehicle tosses. Simple avoid
    it's plasma balls, vehicles toss, shock wave and ribbon beam and the mission is
    all yours. When it die, its brain came oozing out, and fall to it's death.

    Difficulties: HELL-LUVA, Jesus may cry.
    Character Advantage: Clark, Tarma, Marco, Eri, Ralf
    Character Disadvantage: Fio (seriously, she's weaker here.)
    =======================================================================
    
    You appear to arrive on a Golden Gate Bridge with alien seeing and taking parts
    of it as souvenirs. Move forward and kill the two alien, guarding a prisoner,
    which wield out Enemy Chaser. Go forward and get the Super Grenade crate in
    front of you. A mass number of alien will came attacking you from rolling,
    bouncing puke more worms and all. Eliminate all of them and you'll see lots
    crates. Inside the furthers entire crate, there are bomb supply and two fish.
    Rescue two prisoners and start your finger cross. Both will give you Enemy
    Chaser and a Laser gun, but then the alien with their new friend, Eye Alien
    appears in mass numbers. They will attack you from both sides by bouncing,
    rolling, puke more worms, release toxic bubbles and being support by flying
    alien as well, firing their slow projectiles at you. Try to survive the
    onslaught by concentrate fire at one side and throw several grenade at the
    other side and you'll make it out alive. Move forward and four alien came
    rolling down chasing you. Kill it and wait for Makoto Aikawa to show up again.
    Don't shot her, or she'll run away. From here, you can either go down or go up.
    
    Route A
    
    Tarma: Hey, I see a Slug up ahead!
    Marco: A Slug Flyer? Whats it doing here?
    Ralf: Never mind who put it there, I wanna ride it!
    
    Move forward and the bridges suddenly destroyed at the back, move forward and
    take a ride on the Slug Flyer. You'll then be fighting against all the aliens
    in the next stage. Range from flying alien to Unknown Mini-UFO. The parasite
    also joins the fun, acting like a suicide bomber, moving towards you. There is
    also two blue-colored parasites, holding a Super heavy machine gun and Super
    laser gun on their head. Kill both of them and get these items. As you battle
    more flying aliens, an unknown ship appears and sends it's collected meteor do
    the talking. You can't kill it nor destroy it, but you can damage it's hatch so
    that it won't fire it again. More of these things will most likely damage the
    Slug or kill you, so prepare some evading action while destroying the hatch.
    Just as the area is clear, a single UEO will attack you, followed by more
    flying alien and parasite attack you and mini-UFO tries to nail you down by
    pinning you down. Intercept them and you'll see two blue parasites with Super
    Grenade and a grenade supply appears for your trouble, preparing your boss
    battle.
    
    Route B
    
    Eri: Oh my god, there's a C4 Chargers under and above the bridge!
    Clark: Quickly, head to the lower bridge!
    Fio: Wait for me!!
    
    Crawl down the bridge and the bridge suddenly destroyed at the back, move
    forward and... No Slug!?
    
    Clark: Nuts!
    Fio: Hey, what's that above the sky?
    Eri: A bird? A plane?
    
    Wrong, not Superman, rather it is Rootmark, the Martians leader came and lift
    you up, giving you a strange mixture of relieve and odd. You control the Vulcan
    attach on top of Rootmark and also your very survival. Depend on your control
    pad, you move just as your Vulcan move. And the Vulcan can penetrate almost all
    enemy appears on the screen. Parasites, flying alien and UEO will appear to
    annoy you. During this event, with Rootmark not taking any serious help except
    leaning his Vulcan and his ultra powerful brain wave. Maybe his still mad at
    you. Attack the parasites and later more and more parasite with flying alien
    and Mini-UFO appears to attack as well. Survive it and the unknown alien craft
    will appear to stop you. Destroy their hatch and they'll leave you alone. More
    enemy will come by, so blast them out from the sky and move forward for you
    boss battle. Oh, don't forget about the grenade supply and Super Grenade.
    
    When you land, by air or still inside the Slug, you'll ended up in one of the
    Rebel army's Battleship. When you move forward to free the 2 prisoner, the ship
    will rock. Move forward and you'll get a nasty surprise.
    
    =======================================================================
    BOSS BATTLE FOUR
    ALIEN SEA SERPENT
    
    Suitable Weapon: Super Grenade, Heavy Machine Gun, Laser Gun
    
    I don't know how this alien manage to live under the sea when it's suppose to
    be an alien. This serpent has several tricks and a very predictable one.
    However, since this is the boss, don't take it lightly guys, move out!
    
    1st Form Attack: Puking out blue goo that is not good for health, Alien blast
    (Same effect as zombie blast, only longer.) blue toxin cloud
    
    2nd Form Attack: Rotate the area while shooting out blue toxin cloud. Does this
    almost every time during his near death.
    
    When you approach it, the rebel soldiers will run away (CHICKEN!) and the sea
    serpent doesn't feel really well, and starts to puke out blue goo at you.
    Counter fire it on its head and hope that none of the goo won't hit you. Once
    it's puking is done, it will swim down, vanish into the sea. There is a high
    possibility that it attack you from behind, doing it's zombie blast similar to
    what the hero once did when they were in zombie mode. Get near it (or get out
    from the Slug) and stay near the monster while you fired away. Once it finishes
    his zombie blast, it will dive again into the sea. It also has the possibility
    to come from the front, zigzagging it's way then turn to see you. This means
    you'll be standing on top of the creature while you attack it. The creature too
    will respond, puking more blue goo at you. Then once it finish, it will spin
    violently, effectively killing you if you don't jump in the right time. After
    it spins, it will return to the sea.  It also attack you by appearing at the
    back or in front of the screen, rotate several times releasing the blue toxin
    clouds several times in a different direction before it dive back to the sea.
    This cloud is like a heat sensor to your Slug so bail out once it use this
    attack. This attack pattern will repeat at random until you heard and
    explosion. Around this time, the alien is weaker now, starts to attack you by
    rotating the area, and fires blue toxin cloud at you. By now, his body is now
    an easy target. Ralf owns this place here, same goes to Tarma and Eri. Once the
    creature can't take it anymore, it's shell burst out, and starts to drown by
    our beautiful sea water. Mission 4 Complete!

    Final Mission
    
    Difficulties: Straight from Hell, or worst.
    Characters Advantage: The Lot
    Characters Disadvantage: None
    
    Marco: This is it folk, this is where we'll strike hard and fast.
    Tarma: Time to get personal then.
    Eri: Count me in!
    Fio: Me too!
    Clark: Wait until we write this to HQ.
    Ralf: What are we waiting for then?
    =======================================================================
    
    This is it, the final mission. Morden's men came to help for a time being just
    like in Metal Slug 3. This is also a very long mission from underground canyon
    to digging underground some more and enter a hive full of aliens. A cool final
    mission theme and the battle is on. As you approach further, three alien will
    immediately attack you with their rolling attack. This time, killing them well
    wield out more worms than usual. Moreover, the rebel troops won't last long
    too. Use them as shield meat and move further. You also see the Pulverizes, an
    alien that can crush you like a rock. Use this opportunity to learn your new
    foes here. There are even a red colored alien that speeds wildly around the
    stage, killing it will stop it from having a 'spinning' good time. When the
    Pulverizes is done, you'll meet another alien-like tank known as Deflectors, a
    tall green machine that fires at different heights. Move on and more alien came
    crashing the party with the Spider Alien tank, accompany with a couple of Eye
    Aliens. Destroy them and more Pulverizers came down. By now, you should have
    several bomb and weapon crate such as Heavy Machine Gun or Shotgun, don't keep
    them, waste them. You'll get a refuel later. After a hard battle between the
    aliens, the Eye Aliens, the Pulverizes, the Deflectors and Spider Alien Tank,
    the rebel army must have completely wiped out. Move forward some more until you
    have to fight a few more Deflectors coming from both sides. This time, the
    rebel armies is indeed a real help as they attack for you from the front while
    you keep them alive by attacking at the back. After all the green walking alien
    is grind to dust, move on and ride your every own Drill Slug.
    
    Tarma: I wanna ride it!
    Clark: You had your chance!
    
    In the second phase, you'll have to dig your way downward and strike any alien
    ant that came across. Fight and dig your way down and try to intercept the ants
    along the way. They will be an alien beacon that emits a powerful laser beam as
    a defense to their hive. Kill the last alien ant to proceed the hive.
    
    Marco: If only I bring my camera, I'll be rich.
    Eri: Too bad, I forgot to bring my cellphone.
    
    Inside the Hive, you'll see Martians been held captive. Move to one of the
    Martians and set them free, they'll act as a prisoner and will give you an item
    or a weapon/bomb crate. The first weapon you'll receive is a Dual Machine Gun.
    Continue and you'll see that the Eye Alien is making their home here. Free more
    Martians and keep killing those Eye Aliens. You might spot the Spider Alien
    Tank as well, and more Martians, some wield out SUPER Shotgun and Enemy Chaser.
    Continue fighting your way, including saving the last 3 Martians hanging above
    head at the end of the screen, one of them wield out another Duel Machine Gun
    until you're surrounded by Spider Tank Alien on both sides. Deal with them and
    proceed to the next stage
    
    Ralf: Hey Marco, aren't we forgetting something?
    Marco: Huh?
    
    You'll reach what seems to be the main hive and several hostel enemy greeting
    you to go to hell. Show them your pistol and fight back. They will be no rebel
    helping you here, so you'll have to manage on your own. There are two Martian
    you have to save, one of it has a Zangetsu sword while the other one is a
    grenade supply, keep the Zangetsu sword weapon for now. After several
    Pulverizes and Unknown aliens attack you, you'll see a single Deflectors
    projecting a long laser beam towards rotating. Since the terrain is different,
    learn it's capability and understand the weapons power. Destroys it and more
    Eye Alien will greet you with another Deflectors. As you move forward, you'll
    see a new foe.
    
    Marco: What the hell is that!?
    Fio: I don't know, but something tells me it wants revenge!
    
    You'll see a huge oversize Eye Alien moving slowly towards you. Known as the
    Mother Eye, and yes, it seems quite pissed off after you kill her kiddies.
    Attack it's eye for all you care. If you still have the Zangetsu sword, now
    it's the time to use it on the Mother Eye, just slice it at the eye a couple of
    time and it'll go down before Marco could say "General Morden!". Just remember
    to watch your footing though. After you kill the first one, several Unknown
    Aliens will attack you and another Mother Eye will appear. Kill all of it and
    another Mother Eye and more Unknown turns up.
    
    Ralf: Oh, come on! Enough already!!!
    
    Don't worry, that's the last one. Killing the last Mother Eye will open a path
    through it's eyes.
    
    Tarma: ... and here we have the organs, the stomach, the brain and the heart.
    Oh, look! A turd!
    Clark: Make him stop before I do my Argentina Backbreaker on him.
    
    Moving on, go up the ledge and rescue more Martians, guarded by Eye Alien and
    Spider-Alien Tank. The Martian here will giving you a Super Laser gun for your
    trouble. Other Deflectors will appear in front of you and you didnít have any
    room to crouch. Learn the rotational laser beam carefully to by past it without
    any problem. Destroy this Deflectors and another one will replace, repeat the
    same progress and cross over some more, rescuing another Martians, who'll give
    you a Zangetsu Sword but you might see multiple numbers of Eye Alien in the
    area, guarding the ledge and a that particular Martian. Crack it down and move
    forward for a red Unknown and it's normal companion. Use the Zangetsu sword to
    kill the red Unknown faster along with its companion. Mother Eye will appear
    again from the back, this time it's invulnerable to all your attack, with a
    Deflectors in front deflecting it's laser beam.
    
    Clark: Trap between two devils and a hole to oblivion.
    
    Not to worry, kill the Deflectors and rescue the two Martians. A single
    Martians gladly help you fight and another gladly gave you a SUPER Heavy
    Machine Gun as the Unknown appeared from the sky. It also helps you fight off
    one Deflectors in tight situation. Fight it off and rescue the 2 more Martian,
    one gives you a Super Rocket Launcher and an expensive gem worth 30000
    points(!!!). Move Forward and you'll have to fight on an unfair fight against
    major number of Pulverizers. Clark and Ralf are better here, while Marco might
    need some distance away from them. Once all of them are killed, move forward
    and jump up to rescue another Martian at the peak for a bone (!?). Jump
    forward, killing the last Deflectors until the music stops playing. Rescue the
    final Martians for a refreshing grenades. Move forward until you spot several
    parasites grouped together. It burst and one of the character been control by
    the Controller.
    
    =======================================================================
    MINI-BOSS BATTLE
    CONTROLLER
    
    They are several differences in this battle. One, you'll have to damage it
    enough until the controller is destroyed. Two, think of it as a clone back in
    the Metal Slug 3 series. Three, this is Allen stage, used the same strategic as
    you would use against Allen.
    
    This Controller (Marco, Tarma, Eri or Fio) will use their weapon to attack you
    either from Heavy Machine Gun, Flame Shots, Rocket Launcher, grenade or melee
    attack. Since the weapon order is difficult to predict, don't change your
    weapon at all times, remain as default weapon. When the controller change it's
    weapon, a voice will reveal what kind of weapon it will use. Don't try to do
    melee attack as well. The Controller will also use the characters advantage, as
    you would have. Take note that when the Controller switch to Heavy Machine Gun,
    get ready to bail and duck.
    
    a) If the Controller is controlling Marco, he will use pistol all the time, so
    attack above him. Run away from him when he switches to his weapon from Flame
    Shot or Rocket Launcher. When he uses the Heavy Machine Gun, stay away from him
    as he leap and perform a contra like attack. He often throws Grenade though.
    
    b) If the Controller is controlling Tarma, he will do just as Marco did, but
    he'll use Heavy Machine Gun a lot. Like Marco, he often throws grenade, but
    also like to get close to you for some slashing moment.
    
    c) If the Controller is controlling Eri, get ready for some pain. Eri will fire
    her handgun forcing you to duck. When you did, she will throw a grenade at you.
    No matter if your above, side or under, she'll use her grenade rather than her
    other weapons. To force her to change her plan, simple get near her and throw
    some grenade at her. She'll change her tactic and attack you the same pattern
    as Marco. She will reuse her tactic again if you are at ground level with her.
    
    d) If the Controller is controlling Fio, She'll do just as Marco did, but rely
    heavily on Flame Shots, and Rocket Launcher. She's easy to deal with, but watch
    out for her Super Heavy Machine Gun, which turns her into spinning porcupine.
    
    Defeating them is just a matter of time. If you still have a Zangetsu Sword,
    attack the controller by unleashing the weapons tide of waves at it, throw some
    grenade as well for some good messurement as well. When you did it, the
    Controller goes out of control and destroyed itself. The character will regain
    him/her self, gives a thumbs up showing their all right and out of nowhere came
    down a Super Metal Slug. Take it for your Final Showdown.

    FINAL BOSS BATTLE
    ENIGMA (1st FORM)
    
    Attack Type: Yellow goo (does no damage to you or the Slug), Rolling Unknown
    Alien
    
    Suitable Weapon: Slug's Vulcan, Cannon Blast
    
    The first form happens to be a weak and quite sensitive boss. Avoid it's slime
    for fun and retaliate the Unknown Alien, then focus on him again. If the battle
    is too long, Red Unknown alien will appear, but it also trigger the appearance
    of the Rebel forces, helping you out. After a few good blasting moments, the
    boss protection screen is destroyed and the boss came out oozing out yellow
    liquid, defeated. Hands full of Rebel's army arrives and cheers at you. But
    somethings wrong, the boss haven't given up yet, and kills all the Rebel Army.
    Enigma came out from it's sleepy mode and starts to attack you.
    
    ENIGMA (2nd FORM)
    
    Attack Type: Energy blast, Blue Fireballs, Laser Eye, and Scale Energy.
    
    Suitable Weapon: Slug's Vulcan.
    
    Having the Slug still intact, attack it's head with full force, concentrate
    your firepower at his head.  Enigma will use Energy Blast to destroy the floor
    at the center, uses his Blue Fireball from his mouth that fires almost all the
    screen angle. It also uses his Laser Eye, staring at you while firing a blue
    Laser.  Use the Metal Slug trick (Get out from the Slug for a momentarily
    Invulnerable) whenever youíre almost being hit by any of his attack,
    respectively his Blue Fireballs and Laser Eye. Continue to attack his head
    until he perform his last attack, the Scale Energy which it shoots out what
    seems to be his hairy scales. This attack can hit you from multiple sides, so
    prepare to eject and enter the Metal Slug back. Note that the non blue scale is
    actually a power up, mostly grenades and Heavy Machine Gun, but in rare
    occasion wield out Duel Machine Gun and Rocket Launcher. When Enigma continue
    to attack using his Scale Energy, this means he is close to his death. Keep
    firing his head until he loose his balance, dropping along with you in high
    velocity. The boss however isnít giving up the fight and launches MASS NUMBER
    of Scale Energy. Donít escape the Slug unless you really have too. Intercept
    his Scale Energy and watch him plunder to its doom. FINAL MISSION COMPLETE!

    For those who have memorize the walkthrough but still wanna find a way to kill
    the boss without reading the entire walkthrough, here's a little short cut you
    can use. Enjoy blasting away!
    
    =======================================================================
    BOSS BATTLE ONE
    MASTER DRILLER
    
    Suitable Weapon: Heavy Machine Gun, Super Grenade, Flame Shot, Rocket Launcher.
    
    Is it just me, or is this some sort of joke? This boss isn't worth your penny,
    but they make havoc on the surface, might as well destroy it. Morden must have
    come up with this from the Slug Driller. No matter. Time to stop this machine
    once and for all!!
    
    1st Form attack: Raise shield up, releasing some sort of Iron Lizard.
    Destroying it will wield out random weapon crate, bomb supply. Long range
    artillery blast, fires gigantic Stones from their machine's upper hole.
    
    2nd Form attack: Fires gigantic Stones from their machine's upper hole, Massive
    Driller that sometimes fires out it's drill, similar to Drill Cannon from the
    Slug Driller.
    
    This is ridiculous, Morden copy everything the Metal Slug team once has! This
    boss has an Iron Lizard, Stone and even the Drill cannon! His first form is as
    weak as hell, just fire volley after volley of firepower is enough. Watch out
    for their intimidating Iron Lizard though. When a grunt pop out on to of the
    shield, get yourself some covering ground! After you destroy the shield, a huge
    oversize drill will appear and remember to stay away from it, as it sometimes
    starts to drill when you approach it. It also splits out Stones from above,
    thank goodness it's slow though, and evading it is easy. However, don't leave
    the stone where it is, as the Master Driller will use its Drill Cannon. If you
    still have the Metal Slug, simple attack with your eyes close (No, seriously.
    ATTACK with your eyes close.) and watch the monster go down in less than a
    minute.
    
    =======================================================================
    
    BOSS BATTLE TWO
    MONORAIL TANK
    
    Suitable weapon: Laser Gun, Heavy Machine Gun, Flame Shot, Rocket Launcher
    
    The tank that went out of control, speeding down the hill exceeding our laws
    speed limit and the entire team have to destroys in on it's lower deck. To make
    matters worse, this boss even wield out lots of rockets traveling vertically at
    random location. Try your best to fire the huge turret and evade/destroy the
    missile.
    
    1st Form Attack: Launches a hell lot of rockets, launches tomahawk missiles,
    side turrets.
    
    2nd Form Attack: Flak attack, Gigantic Missile attack.
    
    Here's the rules, the 1st form is a monster, it will launches multiple rockets
    that goes vertically from one screen to the next, launches it's tomahawk
    missile at you and pulling out it's side turret. These attacks appear to be
    random. When you see that if it starts to launch multiply attack at once, that
    means it's close to it's death. Attack the Giant turret and defend yourself
    from all the threat it uses. And remember, Heavy Machine gun is your friend
    here. Flame Shot also helps very down this tank, including the laser gun. Just
    as the 1st form is destroyed, get ready for the lord of pain. The upper turret
    slides back and reveal a giant missile silo, launching towards the sky with
    it's flak. Unfortunately, the missile appears to be heavy and starts to fall
    down to earth! Evade the missile's attack and destroy the missile silo. Fire
    bomb works well here, waste it all onto this boss. Then, when the screen
    appears to be zooming out for a long time, get ready to run, evade and gun
    tactics, as the missile will continue to launch, firing flak out and launch
    again. This also means that the boss is near death. Finishing it and celebrate
    your victory after it crash down hill.
    
    =======================================================================
    
    BOSS BATTLE THREE
    ABOMINATION
    
    Suitable Weapon: Dual Machine Gun.
    
    This is perhaps the eeriest boss battle I've ever seen. It has it's brain and
    eyeball on the goldfish bowl there, sharp claws and a small... dick. Thatís
    right. A dick. This is also one of the most long endurable boss you'll fight,
    so get that Slug ready, your going to need it
    
    1st Form Attack: Vehicle toss, plasma balls, shock wave, claw attack, ribbon
    beam.
    
    2nd Form Attack: Goes berserk, multiple plasma balls, longer claw attack,
    ribbon beam, vehicle toss
    
    Don't get near that boss. Seriously, don't get near it. Ralf will be completely
    useless here, so let him get all the duel machine gun or let him ride the Slug.
    Clark can use the Duel Machine Gun well and Tarma can do even without the Slug.
    This boss is a hard nut to crack, your best choice is to attack, move and jump,
    repeat. Use this strategy on the plasma balls. When you see a box appears at
    the back of you, jump on it and wait for the following;
    
    1. If it opens a center hatch, prepare to evade its ribbon beam. Characters not
    riding the Slug will have to predict where the beam is arching, either up or
    down and find the gap for cover. Character on the Slug has to be wise not to be
    hit by the beam. Have the beam goes across the Slugs leg so that the character
    won't be hit by it.
    
    2. It will launch Shock wave, an attack that will kill anyone who isn't above
    the box.
    
    3. It will kneel down and pull out a... vehicle out of nowhere and toss it to
    you. Where did that vehicle came from?
    
    Out of the three attack list, it will keep on launching it's plasma balls
    towards you. So be careful. It will go berserk if you keep on damaging it or
    pissed it off by moving too near, jump back and attack it while it goes it's
    claw attacks. When you see it's brain starts to change color from yellowish to
    near red and sparks like mad, that means it's going to die. Dual machine gun
    can be found each time it does a ribbon attack or vehicle tosses. Simple avoid
    it's plasma balls, vehicles toss, shock wave and ribbon beam and the mission is
    all yours. When it die, its brain came oozing out, and fall to it's death.
    
    =======================================================================
    
    BOSS BATTLE FOUR
    ALIEN SEA SERPENT
    
    Suitable Weapon: Super Grenade, Heavy Machine Gun, Laser Gun
    
    I don't know how this alien manage to live under the sea when it's suppose to
    be an alien. This serpent has several tricks and a very predictable one.
    However, since this is the boss, don't take it lightly guys, move out!
    
    1st Form Attack: Puking out blue goo that is not good for health, Alien blast
    (Same effect as zombie blast, only longer.) blue toxin cloud
    
    2nd Form Attack: Rotate the area while shooting out blue toxin cloud. Does this
    almost every time during his near death.
    
    When you approach it, the rebel soldiers will run away (CHICKEN!) and the sea
    serpent doesn't feel really well, and starts to puke out blue goo at you.
    Counter fire it on its head and hope that none of the goo won't hit you. Once
    it's puking is done, it will swim down, vanish into the sea. There is a high
    possibility that it attack you from behind, doing it's zombie blast similar to
    what the hero once did when they were in zombie mode. Get near it (or get out
    from the Slug) and stay near the monster while you fired away. Once it finishes
    his zombie blast, it will dive again into the sea. It also has the possibility
    to come from the front, zigzagging it's way then turn to see you. This means
    you'll be standing on top of the creature while you attack it. The creature too
    will respond, puking more blue goo at you. Then once it finish, it will spin
    violently, effectively killing you if you don't jump in the right time. After
    it spins, it will return to the sea.  It also attack you by appearing at the
    back or in front of the screen, rotate several times releasing the blue toxin
    clouds several times in a different direction before it dive back to the sea.
    This cloud is like a heat sensor to your Slug so bail out once it use this
    attack. This attack pattern will repeat at random until you heard and
    explosion. Around this time, the alien is weaker now, starts to attack you by
    rotating the area, and fires blue toxin cloud at you. By now, his body is now
    an easy target. Ralf owns this place here, same goes to Tarma and Eri. Once the
    creature can't take it anymore, it's shell burst out, and starts to drown by
    our beautiful sea water. Mission 4 Complete!
    
    =======================================================================
    
    MINI-BOSS BATTLE
    CONTROLLER
    
    They are several differences in this battle. One, you'll have to damage it
    enough until the controller is destroyed. Two, think of it as a clone back in
    the Metal Slug 3 series. Three, this is Allen stage, used the same strategic as

    Defeating them is just a matter of time. If you still have a Zangetsu Sword,
    attack the controller by unleashing the weapons tide of waves at it, throw some
    grenade as well for some good messurement as well. When you did it, the
    Controller goes out of control and destroyed itself. The character will regain
    him/her self, gives a thumbs up showing their all right and out of nowhere came
    down a Super Metal Slug. Take it for your Final Showdown.

    14.Prisoners Location and Hidden Items
    -----------------------------------------------------------------------
    Prisoners, the every individual who seek help and gives you power ups or item
    under their gigantic size bonkers. These guys aren't any normal prisoners,
    their old man who need you to rescue them, all 100 of them including special
    prisoners. Items are there just to be remain hidden.
    
    -----------------------------------------------------------------------
    Mission 1
    
    Normal Prisoners: 25
    Hidden Prisoners: 0
    
    These are normal stage and are not required to locate any hidden prisoner.
    These first mission is just for newbie to rescue them. There are 6 obvious
    prisoner in Mission 1-1, 2 in the next scene and a total of 17 prisoners more
    in Mission 1-2 either the Cliff path (12 prisoners), or the Cavern path (5
    prisoner)
    
    Hidden Items
    
    You'll find your first red gem in Mission 1-1 on top of the tree (Why the heck
    would anyone put in there?) and 3 fish on the illusional mountain in Mission
    1-2 as you approach your eighth prisoner.
    
    -----------------------------------------------------------------------
    Mission 2
    
    Normal Prisoners: 17
    Hidden Prisoners: 0
    
    Another newbie area, this place is just like Mission 1, only different is that
    in Mission 2-2, the Donkey Slug will have to survive long enough to net the
    other 2 prisoners skipping on the gate using the Cannon Convoy. Mission 2-1
    will net you 7 prisoners while the other ten is just along the road, don't use
    the Frontal Attack at all cost until you reach the gate.
    
    Hidden Items
    
    There is 4 spot to 'fish' some fish, at the beginning in Mission 2-1, go back
    and shoot the river downward until you hit something, continue to shoot to net
    3 fish worth 500 points. When you rescue your first prisoner, there is another
    fishing spot at the gap, fire away to net another 3 more fish. Proceed until
    you see a prisoner (who happens to have a firebomb). Don't pick him up yet.
    Instead, jump down between the two gaps until the flying piranha attack you.
    Clear the piranha and shoot the two gap for 3 fish each. You'll also might get
    3 blue gem while you shoot the last final gap. The last hidden Item is rather
    unusual and rare to get. When you hike the hill, continue shooting until you
    hit something, which reveal a bird nest. This item is rare to get and only if
    the rebel plane arrive will you be able to get the nest.
    
    -----------------------------------------------------------------------
    Mission 3
    
    Normal Prisoners: 23
    Hidden Prisoners: 3
    
    Now we have some hidden prisoners here and a special Prisoner, Rumi Aikawa.
    Rescue the obvious prisoner including Aikawa in Mission 3-1 until you reach the
    temple entrance, netting 8 prisoners along the way. Here, approach the temple
    carefully and threw a grenade at the chinese board and run to the other side,
    as the Unknown flood the area and 2 prisoner will be glad to be in the list
    Remember, you must have at all 8 hidden white carrots to get these hidden
    prisoner. Now, going down will net you 6 prisoners, but no hidden prisoners
    here, so head upstairs and rescue 2 prisoners and keep the shotgun until you
    reach an area where the parasite came down for a feast. After all that is over,
    you'll notice that your actually fighting on a rumble place, go to the second
    hill and fire away your shotgun until your meter fills up, shot that spot until
    coins starts to fly out. When there is no more coin flying out, go all the way
    until you see a building drop all the coin and a prisoners. Continue on to
    rescue the rest of the prisoners.
    
    Hidden Items
    
    White carrots, an item that you'll get when you need it so. At the start where
    Aikawa about to leave, shoot the far left lantern for a single white carrot,
    continue on for another white carrot in the air conditioner, shoot the box for
    another and at the end before the jeeb arrives, shot the chinese billboards for
    another. Go up the construction building and shoot up as you go for another
    white carrot. drop down and fire again for another. drop down some more until
    you fought the Unknown. Once your done, shot up one last time for your last
    hidden item.
    
    -----------------------------------------------------------------------
    Mission 4
    
    Normal Prisoners: 6
    Hidden Prisoners: 19
    
    WOW, the number of prisoners here is plentiful. In Mission 4-1, there is a
    hidden prisoner just right after you pick up the first prisoner up in the lamp
    post, above the Super Grenade weapon crate. move forward and rescue more
    prisoners along the way. Makoto will appear as you finish mopping up the last
    four Unknown Alien. From here, the two path will gives you a separate numbers
    of prisoners. Go up and fire the lamp post for 4 prisoners. Do the same if you
    go down the path, fire your weapon at the lamp post at long range for 4
    prisoners and 50000 point fish. Once you've clear from all the flying action,
    rescue two more obvious prisoners and 3 hidden Prisoners above the ship.
    Eventually, you'll have to fight the boss here, but hold on! Don't damage the
    boss too much, you still need 3 more prisoners, coming from the rear of the
    boss fight, which only happen when the boss does a Toxin Cloud attack once. Net
    the last three prisoner and kill the boss for a good measurement.
    
    Hidden Items
    
    None, seriously, none.
    
    -----------------------------------------------------------------------
    Final Mission
    
    Normal Prisoners: 19
    Hidden Prisoners: 1(Unknown Location)
    
    Since I do not know where the heck is the last prisoner in Final Mission, I
    like SOMEONE to contribute it to me as fast as possible, I've been playing up
    until now trying to find the last prisoner
    
    Hidden Item
    
    The First hidden items happen to be the rare gem you'll be looking for, the
    yellow gem. In Final Mission-1, when you approach the area that has three
    crate, firing at the ceiling. If you hit something, move to the next spot.
    There are five spot you must fire, thus reveal a yellow gem at the middle of
    the crate. grab it for a 50000 points. Another hidden item is the hard-to-get
    treasure chest. When you arrive in Final Mission-3, eye aliens nest, when you
    receive your first Duel Machine Gun, carefully go down the slope and crawl
    under the invincible wall. Fire during your entrance to napped three treasure
    chest worth 50000 points. The next area, Final Mission-4, main hive is the
    place to collect the most uncommon item, bones. After you defeat the three
    Mother Eye, jump up and jump over the ledge. In the same time, jump back to the
    ledge and shot the right end screen to napped 2-3 bones. After a furious
    battle, head up and rescue the Martian that gives you the second Zangetsu
    sword, fire above to nap another three more bones. fight your way until you
    encounter two more Martian to be saved. Attack the right end corner to napped
    another 2-3 bones. Then, after your furious battle against the controller, dont
    jump on the Slug. Simple wait at the middle of the stage until the extented
    time is finish, your character will move on it's own, but also napped Bird
    Nest, doll and the rare item of all, the cat.
