Introduction First off, Metal Slug 6 is a 2D side scrolling shooter that was released as a tenth anniversary edition of the game series. The other games in the series are Metal Slug, Metal Slug 2, Metal Slug X, Metal Slug 3, Metal Slug 4, and Metal Slug 5. Recently, the Metal Slug Anthology features all seven of these games on one convenient package. If you have the anthology, this FAQ might be of some use to you as it can help you beat Metal Slug 6. Something new in Metal Slug 6 not previously seen in other versions are the new characters, weapon stock system, and character specific abilities. Another major difference is the fact that you can select one of two modes, Hard or Easy. Note that the slide ability in Metal Slug 5 has been scrapped. It does not appear in this game and its removal is probably a good thing. In Easy mode, the game is easier. In this mode, your default weapon is the Heavy Machine Gun [H] with infinite ammo. Also special weapon ammo supply is doubled. The drawback to Easy mode is that you cannot play the final mission so if you want to play the last level, you have to choose hard mode. For the easy mode bosses, they have several powerful attacks that they do not use. I will outline these differences in the boss strategies. In Hard mode, the game is similar to previous Metal Slug games. Only in this mode can you access and play the final mission. Also your initial equip is the handgun with infinite arms off course. Compared to Easy mode, your special weapon ammo supply is halved. Note that you can pick up the Heavy Machine Gun [H] in hard mode, but not in easy. 2. Controls On the arcade version of the game, there are 5 buttons, A-E and an 8 direction joystick. On the arcade machine I play on, they are in the following arrangement: ABC DE The A button fires your weapon. B is the jump button. C is the grenade button. D is used for the Frontal Attack or the Slug Suicide if you are riding a Slug. For Ralph and Clark, pressing up+A+D is the command for doing their special attack. The E button is for changing your weapon. Aside from the normal controls, there are several other commands that are unknown to most newbies and I will now elaborate them. First off, to jump off your Slug, press down and the jump button. Note that from the time you dismount to the time you land, your character is invincible. This command is very useful and is necessary to defeat some bosses. Another neat trick is that while riding a Slug, you can throw your normal grenades by pressing down and the grenade button. The upside of throwing grenades from inside the Slug is that you can throw them at a much faster rate. Some other not so known, but not as important commands include the weapon discard. It is performed by pressing C and D simultaneously. Also, pressing A and D at the same time will cause your character to do a melee attack. 3. The characters In this game, there are six characters each with different special abilities so on the character select screen, pick the one whose abilities suit you the best Marco: He is the team leader and his special ability is that his initial weapon is stronger than everybody else. Normal ammo supply and grenade supply. Fio: Fio's special ability lies in the fact that she starts each life with a Heavy Machine Gun [H] with 150 arms. She also has increased ammo supply. I have heard that her handgun is weaker than everybody else, but I have yet to confirm this. Tarma: Tarma's special ability lies in the Slugs. Whenever he rides a Slug, he has increased firepower and automatic Vulcan Fix. Vulcan Fix allows the player to hold the fire button and the Slug Vulcan will keep rapid firing in one direction. This ability is good as you gun will not change angle when you move left or right. When ever Tarma rides a armoured Slug, it the damage it takes is halfed. Normally Slugs lose 1/3 of health when hit, but with Tarma, it will only lose 1/6 of its health. Eri: Eri's special ability lies in her grenades. She gets 20 of them at the start and has the longest throwing range. She can also aim them in the four directions. I also believe that they do more damage than normal. Ralph: Ralph is a special guest character from the King of Fighters and Ikari Warriors games. Perhaps his best ability is that if he gets hit, he will come back to life, essentially giving you double life against most attacks. One catch on the double life ability is that there are some attacks that will kill him in one hit no matter what. While Ralph has double life, he has half ammo for all special weapons and grenade crates. He does start with 10 grenades, but every grenade box gives 5 instead of the normal 10. Ralph also has a special melee attack called the Vulcan Punch that causes major damage to enemies. Clark: Clark is the second special guest character from the King of Fighters and Ikari Warriors games. His special ability is the Argentine Backbreaker. This special move can only be used on organic enemies in melee range. When used, most organic enemies die in one hit and every use scores a large amount of points which increases with more combos up to a certain limit. Note that when the special is used successfully, Clark becomes invulnerable for a second or so. Here is a video I found of someone racking up a lot of points using Clark's special: http://www.youtube.com/watch?v=aGfXO3VMZNM 4. Weapons: Handgun: Symbol: None This is your initial equip in Hard mode. In easy mode, the Handgun is replaced by the Heavy Machine Gun. Arms: Infinite Power: 1/5 Range: 3/5 Speed: 4/5 Rarity: Initial equip This is your initial weapon and luckily it has infinite arms. It is best used to conserve the ammunition of special weapons when facing a small number of enemies. Note that Marco's Handgun is stronger than normal as that is his special ability. Its weaknesses include having the worst attack power of all the weapons. Also, it cannot shoot diagonally so taking out enemies up high might be difficult as you need to stand under them. Overall, use this weapon to save the ammo of special weapons or learn to love it if you don't have any special weapons on you. Note that some enemies can deflect the shots of this weapon. Knife: Symbol: None This is your standard melee attack that is used whenever an enemy gets close to you. Power: 2.5/5 Range: 1/5 Speed: 3/5 Rarity: Initial equip Every character comes with a melee attack which is the knife. Ralph's is the best at melee as his knife attack is fastest of the entire cast. The melee attack is useful to kill off organic enemies that are close to you. In later levels, knifing can be better than the handgun as the knife attack can kill some enemies faster than the handgun. Also, some enemy attacks Grenade: Symbol: A crate full of shells This is your standard bag of handy grenades that every solider has that can be very helpful in your battles. Initial arms: 10, Eri 20 Pick up arms: 10, Eri 20, Ralph 5. Power: 3/5 Range: 3/5 Speed: 3/5 Rarity: Common This weapon can be used by pressing the C or the grenade button. What happens is that your character pulls out a grenade and throws it forward. Eri has a longer throwing range and she can aim then with the joystick. After the grenade is thrown, it bounces for a little bit and explodes upon contact or after it stops bouncing. It is best used to take out armoured tanks or enemies downhill for you. Sometimes, grenades can be a life saver as they can usually take out an organic enemy that is just about to hit you before they hit you. Grenades can be found from prisoner drops, crates, or certain enemy drops. The Grenade does not have many weaknesses apart that it has low range. It is a pretty good balanced weapon that will be very useful. Firebomb: Symbol: A bottle with the word Fire on it. This weapon is basically an extension of your normal Grenades. By grabbing a fire bottle, your normal Grenades turn into Fireombs. Note that if you have Firebombs and you grab an item that says "Bomb" your Grenades will return to normal. Arms: 10 and it converts your normal grenades to Firebombs. If you pick up a bomb box, while having Firebombs, they won't revert to normal grenades. Power: 3.5/5 Range: 3.5/5 Speed: 3/5 When thrown, a bottle resembling a Molotov cocktail containing flammable material hurls towards the ground or enemy. If it hits the ground, there will be a flame wave that erupts around the contact point that incinerates nearby enemies. Note that if you hit an enemy directly such as a boss, there will be no splash damage, but the hit will be slightly stronger. The advantage over normal grenades is that it has a larger blast radius. The biggest weakness of the Firebomb is that it cannot roll as it explodes upon contact with the ground. Heavy Machine Gun Symbol: [H] This is the most common special weapon found in crates, prisoners and some enemy drops. Comes in normal and Super versions. The Super version will have a pulsating H and the icon is slightly bigger. The difference between normal and Super is that the Super Heavy Machine Gun one has more attack power as indicated by the slightly larger shot. Arms: 100 Power: 2/5 Super power: 3/5 Range: 5/5 Speed: 4/5 Rarity: Common Super Heavy Machine Gun Rarity: Uncommon This general purpose weapon is best used on large numbers of organic enemies. On single organic targets, it is quite a waste unless facing some of the stronger enemies on the final mission. Against tanks, it is moderately effective, but better than the handgun as it packs more power. This weapon is the initial equip of Easy mode and will not appear as a drop in this mode. Note that the super version of this weapon appears in the fourth level of easy mode. I believe that picking up the Super Heavy Machine Gun in easy mode does nothing. The Heavy Machine Gun's only weakness is that it might not have enough power to take out swarms of stronger enemies in the later levels, mostly in Mission 3 and onwards. Another bad thing about the Heavy Machine Gun is that it consumes ammo at a high rate. Note that some enemies can deflect the shots of the Heavy Machine Gun. Rocket Launcher: Symbol: [R] This weapon is first found in Mission 1 and is dropped by crates, prisoners, and some enemy drops. Comes in normal and Super forms. The Super one has more attack power. Arms: 10 Power: 3/5 Super power: 4/5 Range: 3/5 Speed: 2/5 Rarity: Uncommon Basically this weapon shoots a large missile in the direction you are pointing in. It can only be fired in four directions and has limited homing ability. This weapon is best used on armoured units such as tanks and bosses. The Rocket Launcher's biggest weaknesses include a slow firing rate. This weapon cannot be fired rapidly as there is a limit to how many missiles can be on screen at a time. Also, it is not very effective against swarms of organic enemies as a result of its poor firing speed. In addition, it has poor homing ability and it cannot strike diagonally. On a side note, the Rocket Launcher is pronounced similarly to "Rawket Lawnchair" by the announcer voice. Not critical to gameplay, but a funny joke to some. Enemy Chaser: Symbol: [C] This weapon is similar to the Rocket Launcher with a few differences. Arms: 10 Power: 2/5 Range: 4/5 Speed: 3.5/5 Rarity: Uncommon What this weapon does is that it shoots a homing missile in the direction you are pointing in. What direction you point in does not really matter as it will home on to nearby enemies regardless of direction so it is possible for the shots to go behind you. It has a much higher firing rate than the Rocket Launcher at the expense of power. This weapon is best used against armoured or flying units. It is decent against a swarm of organic enemies as it has a large blast radius that can take out multiple targets. Compared to the Rocket Launcher, it has lesser power so this is its greatest weakness. Also you will probably find that rapid firing of this weapon will cause it to be used up very quickly. Flameshot: Symbol: [F] This weapon is like a portable barbeque. Comes in normal and super varities. Arms: 10 Power: 4/5 Super Flameshot power: 5/5 Range: 2/5 Speed: 1/5 Rarity: Rare How this weapon works is that when you fire, a large red blast of fire comes out of your gun. It is great at roasting enemies alive and most organic creatures die in one shot. The Flameshot is similar to the Shotgun with the only difference is that the Flameshot is multihit while the Shotgun is a single hit. The main advantage that the Flameshot has over the Shotgun is that its shot lasts slightly longer. Note that this weapon is great at negating the shots of Martians. While the Flameshot packs a powerful punch, it comes at the expense at speed and range. With its horrible range, the Flameshot is a semi-melee weapon. Also, since it is a multi hit weapon, in order to do full damage, the enemy must be in contact with the shot for the entire time. Iron Lizard: Symbol: [I] This weapon is found in the Mission 1 and it looks like a toy car... Arms: 10 Power: 3/5 Range: 2.5/5 Speed: 3/5 Rarity: Uncommon Basically this weapon is a missile on wheels. When fired, a rocket drops to the ground and rolls towards an object and explodes upon contact. It is only good on armoured units on the ground or enemies downhill from you. For the most part, this weapon isn't that great as it can only hit ground enemies. Although it can be fired upwards, it doesn't go very far as it drops back on the ground thus making it useless against aerial enemies. Also, if the ground is not even, it will have difficulty reaching a target as it will blow up when it crashes into a wall. Basically, this is the second worst weapon, as your Handgun might just be better than it. Laser Gun: Symbol: [L] This is a rapid firing weapon similar to the Heavy Machine Gun that is first found in Mission 2. Comes in normal and Super varieties. Arms: 100 Power: 3/5 Super Laser Gun power: 4/5 Range: 5/5 Speed: 4/5 Rarity: Uncommon Super Laser Gun Rarity: Very Rare This weapon is similar to the Heavy Machine Gun, but instead of yellow shots, it shoots out a continuous laser. Usage is similar to the Heavy Machine Gun, but the Laser differs from the fact that it has more attack power. Great against large swarms of enemies or armoured units and the additional attack power means that it can cut through stronger enemies with ease. Also, its shot cannot be deflected by the reptilian aliens in Mission 3 onwards. The Laser Gun's biggest weakness is that it consumes ammo at a ridiculous rate. Drop Shot Symbol: [D] This weapon is so bad that your Handgun is better than it. First found in Mission 2. Arms: 10 Power: 2/5 Range: 2/5 Speed: 2/5 Rarity: Rare How this weapon works is that when you fire, a small bouncing ball will come out and bounce its way slowly towards your enemy. You can only shoot three at a time and they move very slowly towards the enemy. The Drop Shot is only good if you are right up next to an enemy tank or if an enemy is downhill from you. Overall, this weapon is purely crap and is indeed the worst weapon in the game. It is bad in most situations and your Handgun is definitely better than it. In other words, if you have other weapons in your stock, leave it. If you have nothing but your Handgun, you might still want to leave it. Shotgun: Symbol: [S] This slow, but powerful weapon makes its first appearance in Mission 3. Comes in normal and Super varieties. Arms: 10 Power: 4/5 Super Shotgun power: 5/5 Range: 2/5 Speed: 1/5 Rarity: Rare Super Shotgun Rarity: Very Rare, only found in Final Mission. What makes this weapon great is that it packs a mighty punch with a single shot. One shot will take out most organic enemies in one hit and tanks are destroyed quickly with this weapon. What the Shotgun has in pure power, it sacrifices speed and range. Each shot is a large blast in front of your character so you have to be somewhat close to your enemy. It can only fire in four directions so it might be hard to hit aerial enemies. Also, the Shotgun is quite slow so each shot must be accurate or else you might be screwed. Zantetsu Sword: Symbol: [Z] The best melee weapon you will ever get. First found in Mission 3. Arms: 10 Power: 4/5 Range: 1.5/5 Speed: 3/5 Rarity: Rare When equipped with this weapon, your character basically has an insanely powerful knife attack that just rips enemies apart. Since it is a melee attack, you need to be close to the target. Unlike your normal knife, it works wonders on armoured and even has the ability to negate enemy shots. Like your knife, you can only attack left and right. Overall, the biggest weakness is the lack of range and firing direction as it is the only weapon that cannot be fired up or down, but its high speed and insane attack power makes up for this disadvantage. Dual Machine Gun Symbol: [2xH] (The in game symbol is of normal size off course) The Dual Machine Gun has the highest firing rate of any weapon in the game. First found in Mission 3. Arms: 200 Power: 4/5 Range: 4/5 Speed: 5/5 Rarity: Rare The Dual Machine Gun is an upgraded form of the Heavy Machine Gun featuring more firepower. When you get this awesome weapon, your character wields two machine guns instead of the usual special weapon rifle. Basically is one of the best weapons in the game and will help you greatly in combat. What the Dual Machine Gun is good against are large swarms of powerful enemies. It has enough firepower to take out masses of enemies with ease. Tanks fall quickly under the sheer firepower of this weapon. With this ridiculous amount of rapid fire, most enemies fall with ease and it makes quick work of bosses. At the expense of a ridiculous firing rate, the Dual Machine Gun burns ammo up at an insane rate. Pressing the fire once can use up at least 8 shots. As such, it is a complete waste to use the Dual Machine Gun against single targets. As such, take care not to waste the ammo whenever it is not necessary. Super Grenade: Symbol: [G] A rare weapon that is packs an explosive punch. First found on the alternate route of Mission 1. Arms: 10 Power: 4/5 Range: 3/5 Speed: 2.5/5 Rarity: Rare This weapon works similarly to the Rocket Launcher. It fires a smaller shot, but the shot deals more damage. This weapon is best used against armoured or strong organic units as it is a complete waste on lesser enemies. Overall, this weapon still has the weaknesses of the Rocket Launcher, but is still better than it because of its higher attack power. Bullet Box: What this item does is that it increases the ammo of a special weapon proportional to how much it starts with. The weapon that receives the ammo restoration is the one that you are equipped with when you grab it. Note that if you grab it while using the Handgun, you will get nothing and the item is wasted. Gas: This isn't really a weapon, but more of a health pickup. It restores a third of a Slug's health. Has no effect if you grab it outside of a Slug. It is only found in areas where you are likely to have a Slug. Note that this is a rare item that only appears twice in the game. The above section I have listed details all the essential and important items that will aid in beating the game. All other items you can find function only to give you bonus points. 5. Slugs Q: What is a Slug? A: A Slug is one of the various vehicles that you get to ride throughout the game. Each have their own characteristics and I will describe them in detail. Metal Slug This is the famous super tank that is found in all of the Metal Slug games. This Slug is armoured as when you enter it, a health bar will show up at the top of the player status. Each hit will normally decrease its health by 1/3 until it is destroyed. For Tarma, the Slug has double durability so each hit does 1/6 damage instead of 1/3. If the Slug runs out of health, an arrow saying "Out" will appear so press jump to escape the Slug before it explodes on you. The Metal Slug is found in Mission 1. If you happen to complete Mission 1 with the Slug, you will get a point bonus at level completion. The Metal Slug is armed with a Vulcan that fires blue shots rapidly. The gun's direction changes as you move around. It also has a cannon that fires a powerful shell to the right. Note that the Slug cannot turn around so the cannon is only effective towards enemies to the right. In addition, the Metal Slug can run down enemy soldiers as a melee attack. The Slug is unharmed by knife attacks. Unlike the other Slugs, the Metal Slug is the only one that can duck like your solider, enabling it to avoid a lot of attacks. While ducking, if you press the grenade button, normal grenades will be thrown at increased speed. Lastly, if you press the D button for the Frontal Attack, your character will jump out and the Slug will run towards the right, running over enemy soldiers before self destructing into something for massive damage. Donkey Slug This Slug is first found in Mission 2. Like all animal Slugs, it has no protection so if you get hit; your character falls off and dies. Note that if you die while riding it, the Slug is will still be there as it is indestructible from enemy fire. The Donkey Slug is equipped with a Vulcan that fires larger, stronger, oval shots. Initially, the Donkey Slug has no cannon, but near the end of Mission 2, it picks up a cart accessory that gives it the cannon. Something notable about the Donkey Slug is that it is quite slow, which makes dodging enemy fire a little difficult. To counter this, jumping while moving can increase movement speed by a little bit. In addition, the Slug dismount was boosted significantly as when you jump off, your jump is a lot higher than the dismount jumps of other Slugs, making it easier to retreat to the opposite side of the screen. Also, the cannon accessory acts as a platform that gives you the extra height needed to reach some items or prisoners. If you happen to suicide the Donkey Slug, your character will jump off and the Slug will charge towards the right with the Slug Vulcan flying off and exploding in mid air. Note that, after the Slug Suicide, the Donkey can be found running back towards the left so it technically never dies. Although it comes back, you can't get back on it again. Slug Gunner Prototype The Slug Gunner Prototype is found right before the boss fight of Mission 3. Unlike the other Slugs, it has automatic Vulcan fix. However, this Slug has no protection so if you get hit, your character is toast. It is equipped with a cannon that can fire either left or right, depending on what direction you are facing. The Vulcan has an angle of 90 degrees, but you can turn the Slug around. Like the Donkey Slug, it cannot be destroyed by enemy fire, but your character will die if hit. The only way for it to be destroyed for good is if you suicide it. Also, it is the fastest Slug in the game, with a movement speed slightly higher than your character. Slug Flyer This Slug is found right before the aerial section of Mission 4. The Slug Flyer is basically an airplane with a Vulcan that can only fire towards the right. Instead of a cannon, the Slug Flyer has powerful missiles. If you manage to keep the Slug alive to the boss, it will make fighting the boss a lot easier. Like the Metal Slug, it is armoured and can take 3 hits before exploding. If it does run out of health, jump to eject before it blows up. Slug Driller This is the newest Slug of the Metal Slug series and it is found near halfway through the Final Mission. It is equipped with drills that can destroy the ground in the subterranean section of the Final Mission. The Slug Driller is equipped with dual Vulcans that are absolutely crap unless you are Tarma. The Vulcan can destroy the ground, but is not as effective as the drill. Controls for the Slug Driller are quite complicated as they are somewhat inverted. First of all, the Vulcans face the opposite direction you are moving in, thus away from the drill, unless you have Vulcan Fix with Tarma. For some reason, the Vulcan firing rate was horrible unless you are using Tarma which in this case is normal. Instead of a standard cannon, this Slug uses mines that explode when enemies contact it. Note that this is the only inescapable Slug so if its health runs out, your character dies with it. Also, Ralph's double life effect does not work here. If you do die in the Slug Driller, another one will reappear with your character inside it. Note that the Slug's mines reset to 10 when you respawn. 6.1 Mission 1 Before I start on the walkthrough, I would like to note that this guide is written primarily for a single player game. While playing two player co-op is not much difference, most strategies are designed for the single player game. At times that I will discuss about two player strategy, I will make that explicit, therefore, assume that all conditions are single player. For the most part, the only difference between single player and two player is that the weapon drops may vary slightly in terms of quantity. The types of weapons found will still be the same, just that the quantity might be slightly different. Also, since there are two players playing, your combined firepower is essentially doubled. Overall, it is easier to beat the game on two player mode just because you have more firepower from two players. Note that both players cannot choose the same character though. Mission one is a somewhat long, but easy first level. Most will find that they can beat this level without dying so the end of level bonus can be large. This level starts by your character parachuting down to a grassy field. Run towards the right and you should find a couple of soldiers guarding a prisoner who is tied up. Shoot them with your Handgun and free the prisoner. He gives you a Heavy Machine Gun. Next you should find a scouting soldier on top of a platform. A weak tank will appear so shoot it with the Heavy Machine Gun and it will fall quickly. Note that this tank attacks by shooting a slow homing missile. Next, a truck containing soldiers will back up onto the screen. At this point, you might as well use up the Heavy Machine Gun as you will get two more special weapons slightly. Keep shooting the truck or use your Grenades and the if you want, shoot the scout and you should rack up a lot of points due to the combo system. If you are using Ralph, two Vulcan Punches will take care of the truck. After dealing with the truck, you should get a Rocket Launcher. Next, there will be some shielded solders standing on some boxes. As more enemies come onto the screen, you can take them all out by blowing up the danger barrel. Jump upwards and you should find a set of two crates. One contains Grenades and the other one an Enemy Chaser. The Enemy chaser should take care of all the enemies and the tank that appears. Next there will be a set of mine soldiers. They run at you and dive, dropping a mine on the ground. The mines only explode after a certain time, but just to be safe, jump over them. Knife or shoot the solders and proceed right. Next, you will find a towering tank. You can kill it quick by throwing Grenades or by doing one Vulcan punch. It attacks by shooting a rolling bomb. Watch the soldiers that appear behind you though. On the downhill section, more mine soldiers will appear and you can find another prisoner that gives you a mushroom. As you run towards the docks, care not to fall into the water or else you will lose a life. Another shield soldier will appear. Since nothing else will come, you can take your time and shoot it with your Handgun or kill it quickly with one Grenade. Jump and proceed and you should find a helicopter above you. When it appears, you can jump and throw some grenades at it. To kill it, shoot upwards and move slightly right or left to avoid its dropping bombs. After defeating it, it will drop a letter that gives you points. Continue jumping and you will find two prisoners and some soldiers near a mortar launcher. Shoot them quickly and proceed right. Keep going right and you will find another shield guy and some other weak soldiers. Another prisoner will give you a Heavy Machine Gun. You might want to save it to blow up the running train that appears next. On the train part, shoot upwards and the containers will explode. Note that the handgun does not have enough power to effectively destroy the containers. Most of the containers contain point items such as food. The most important thing to shoot is the container that contains the Metal Slug. Shoot it and it will fall so hop in for a ride. After getting the Slug, the last containers have bazooka solders on them. They only die if you destroy the container they are on. Also the other containers have cannons that shoot rockets. If you are playing two players, it is best to focus your fire on one container at a time. By focusing your fire, you can destroy more of the containers in less time and grab the items inside them. Also, focus firing can neutralize the threat from the bazooka soldiers or the cannon containers faster. Go right and now you are about done half of the level. Next there will be more soldiers and a prisoner that gives an Iron Lizard. Kill more of the mine solders and proceed right. Next you will find a mountain base with a mass of bomb throwing soldiers and a helicopter. First kill off the mortar and then focus on the helicopter while running over soldiers that get close. The Danger barrel can be destroyed to kill off enemies close to it. At this point, you can either go right or up. Going right is the normal easy route and up is the harder alternate route. If you want to beat the level quickly and easily, take the right route. The up route is harder, but you can get more prisoners and points there. Some might find the normal route too easy and for the better players, the alternate route might be a better challenge. First, I will discuss the normal route that you can take by going right. As you go right, you should find a large metal gate and some bats flying. To advance, you must destroy the gate in front of you. There is no need to waste your special weapons so just use the Handgun or Slug Vulcan. The bats can be shot for fun for some extra points. There are no enemies at this part. Destroy the door and you will find a cave. In the cave, there are some soldiers hiding behind some sandbags. Destroy the sandbag bunkers or lob a grenade/ cannon shot to kill off those soldiers. In the air, there are a couple of prisoners and one will give you a Flameshot. Next, there will be a few tanks that look similarly to your Metal Slug. Stay far from them and keep shooting them until they die. Note that there are bats in the sky so you can shoot them for extra points. Soon, you will be caught in a depression and a large wave of soldiers will come left and right. Keep shooting left and right and run over those that get close with the Slug. After destroying the last tank, you can advance to the boss by blowing up the door behind the tank. The alternate route can be taken by going up instead of right at the base of the mountain area. By going up the go arrow will point up instead of right. Jump across the gaps and make sure not to fall to your doom. There will be a shield soldier waiting for you. Throw a grenade or shoot it with your Slug. As your proceed up, there will be more soldiers including ones armed with shields and bazookas. The bazooka ones are more threatening so kill them first. To take out the shield one quickly, just run him over with the Slug or toss a grenade. A little way up, you can find some more prisoners and one will give you a Heavy Machine Gun. Keep going up and eventually you will meet a helicopter. This foe is quite threatening so take it out quickly. Next, some paratroopers armed with bazookas will drop from the sky. Kill them before they have a chance to shoot. Keep going up until you reach the top. Soon you will find yourself dropping by in a warehouse full of prisoners hanging by the ceiling. Free them and kill off the soldiers. One of these prisoners will give you a Super Grenade weapon for the boss. If you take your sweet time killing off the enemies, more soldiers will come which can be either bad or good. Good if you want to rack up serious points with Clark, bad if you just want to make it out in one piece. In addition to the soldiers, there are a few tanks here. Some shoot missiles while others will shoot three fireballs. The fireballs can be avoided by ducking. Note that in order to advance, the tanks must be destroyed. After clearing this area, you will find yourself at the boss room. 6.2 Boss 1 You enter the room and soon find yourself fighting a large yellow bulldozer like tank. This boss is relatively easy and can be taken care of with no deaths in a fast manner. The character that has the advantage on this boss is Tarma just because of the Slug. With Tarma the boss can fall in a minute or so, possibly less. There are no character disadvantages on this boss. In his first form, the boss has a shovel in front of him. He attacks by shooting a small cannon that has low to mid range. To avoid this attack, either stay far away on the left side of the screen or you can use the Slug dismount trick to avoid it. If you want to kill off the boss fast, it is recommended to stay close to the boss as you will be able to hit it with your cannon, your grenades, and your Flameshot. Dodge the cannon attack by using the Slug dismount trick. If you are using Ralph, you can Vulcan Punch the boss if you want for major damage. His other attack is that the shovel will rise up and an Iron Lizard will appear. If you destroy the Iron Lizard, you can get some power up. If you take too long, the boss will move forward and reduce the amount of battle space you have which means that his later form attacks can hit you despite the fact that you are as far as possibly can from him. His second form starts when the shovel blows up and breaks off. Next a drill will appear in front of him. At this point, he will attack with a rock launcher that is located at the top of the boss. The rocks try to aim towards you, but cannot get you if you are in melee range. To dodge this attack, either be as far as you can from the boss or be in melee range. After the boss shoots the rocks, they will stay on the ground and hinder your movement across the screen. Also, if you don't destroy the rocks, the boss will use the drill attack. Note that since the boss moves closer towards you as the battle goes on, there might not be enough range to avoid the rock attack by going on the far left side of the screen. In this situation, get in melee range. The drill attacks vary for easy and hard mode. In easy mode the drill always go diagonally upwards. This causes a rock shower to fall from the sky. The rocks can be destroyed with the Heavy Machine Gun quite easily and some will yield items. On hard mode, the drill will not go upwards, but horizontally towards you. The drill alternates from high and low with the high attack starting first. This is possibly the hardest attack to dodge of the boss as it has a lot of range. Note that the range of the drill is not necessarily the entire screen, but since the boss moves forwards as time progresses, it can cover the entire screen. Dodge the high attack by crouching. To dodge the low attack, jump over the drill bit. It is safe to touch the rope the drill is attached to, but be prepared to jump again when the drill bit retracts. Note that the second before he does the drill attack, the drill will spin for a second before it flies towards you. Also, when the boss uses the drill, it means he is near death. Finish him off and Mission 1 Complete! After completing the mission, you will get a point bonus depending on your prisoner count and wither you have the Slug intact or not. This is probably the level in which you will receive the largest bonus so savor it while you can. 7.1 Mission 2 Ok you have finally beat Mission 1 and now it is on to Mission 2. Mission 2 is slightly harder than Mission 1, but a little bit shorter. This level might be hard for some novices, but it will only get tougher from now on. You start the level on some wooden dock like area with water underneath. Run across right and you find a new enemy, the axe wielding madman. These guys look like the native villages and they don't like presence. These enemies attack by either swinging their axe at your or by throwing a stick of dynamite. The dynamite attack does not explode on contact, but only after a certain amount of time. Occasionally, there is a madman in a makeshift raft below that throws dynamite sticks upwards towards you. Note that the axe men can take more punishment then regular soldiers. To kill the guy in the raft, jump and shoot downwards. Kill off the axe man and proceed right. You should find a prisoner and he gives you a point item. Jump across the hole and don't fall as that will mean certain death as your character cannot swim. The first crate contains a Heavy Machine Gun. A set of axe men will jump over the fence and try to ambush you. There is no need to use your Heavy Machine Gun. Either kill them with your Handgun or run knife them before they can attack. A couple more axe men will appear and you can find a box on a lower level. The crate contains a Laser Gun. Note that the upper platform is shorter than the lower platform. Drop down from the upper platform and land below, careful not to die in the hole. Grab the Laser Gun and jump right. More axe men will come so knife or shoot them. Jump over the hole and a prisoner will give you a bullet box. It is best to give the ammo to the Laser Gun. Shoot the prisoner above you to free him. Next, there will be a tank to the right on a platform that launches missiles. The missiles tend to land in the middle of the area so to kill it, stand underneath and shoot it. This tank has quite a bit of health so it might take a while to kill. If you are using Ralph, you can jump into it and give it a Vulcan Punch to kill it quickly. The higher angle the missile tank fires at, the less range it will have. Note that more axe men will come and if they can't melee you then they will throw dynamite sticks. Proceed right and take the upper platform as piranhas will attack the lower platform. A prisoner will give you a Firebomb power up. As you proceed right, there are two prisoners on a platform. One will give a Laser Gun and the other will give a bullet box that you should give to your Laser Gun. At the final part of this area, a large swarm of axe men will come from all directions. Note that there will also be enemies ranging you from below. The axe men keep on coming and the only way to advance to the next part is to destroy the wall to the right. On the next part, you will be on a hiker's path that slopes upwards. The first prisoner will give you a Dropshot. If you have both a Heavy Machine Gun and the Laser gun, don't grab it as it crap and not effective in uphill combat. Next, you will find a new enemy, the Martian. He attacks by shooting out blue bubble shots that slowly home towards you. These shots can be destroyed by shooting or crouch knifing them. If there are a lot heading towards you, throwing a Firebomb will destroy a lot of them. Go right and kill off the Martians. When they die, they squirt out green guts. As you proceed right, you will find a wooden bridge with a prisoner that gives you a Super Flameshot. Next a mass of Martians will drop from the air. If you want, the Flameshot can take out multiple enemies with one shot, provided that the enemies are in range. After killing the Martians, you will find the Donkey Slug. On the next section, a regular soldier will try to sneak up on you. Also, UFO enemies will fly above you and try to kill you with their Laser attack when you are directly below them. The Slug Vulcan has enough firepower to kill off UFOs above you provided that you aim straight up. The Heavy Machine Gun also has enough power to kill off the UFOs before they attack if you are playing easy mode. If you find the Slug too slow, you can slightly increase the movement speed by jumping while walking. Next, you will find a camp. Kill off the scout before he can sound the alarm and go right. Soon after, you will find the Donkey Slug cart accessory which gives the Slug its cannon. Also this cart acts as a platform to help you reach items or prisoners upstairs. At this point, this is the hardest part of the entire level. You will soon find yourself swarmed by multiple enemies of different type and is difficult not do die here. First off, I will list the priority of enemies that you should take out. If you see bazooka soldiers, kill them first as they can be deadly in the confusion of combat. Next off should be the Martians. There will also be jumping knife soldiers that try to knife you. If they get too close, dismount the Slug and jump backwards. The shield soldiers are not much of a threat, but they can protect other enemies so knife or bomb them if they block your normal shots. If a tank appears, use your bombs or Slug cannon. Don't bother killing the UFOs as your fire power is best used to deal with the Martians or other enemies. Just make sure you keep moving left and right so they can't hit you. Note that the crate on top holds a Rocket Launcher. To grab it, dismount the Slug and land on the Donkey cart. Jump to touch the Rocket Launcher and the prisoners. One of the prisoners here will give you a Zantetsu Sword, but it is not of much use. Also, another prisoner will give you a bomb crate. As you keep going right, you will find a Haduken prisoner that shoots energy balls at enemies. If you see tanks, kill them fast with the cannon. These tanks attack by shooting fireballs that are hard to dodge if you are on the Slug as it is too tall, so that is why they need to be destroyed quickly. Since this is the end of the level, you might as well shoot out the Slug cannon as you cannot take the Slug to fight the boss. The end of the level is marked by a wooden door that must be destroyed. After collecting the last two prisoners, you can suicide the Slug if you wish. Destroy the door and head to the boss. 7.2 Boss 2 At the boss area, you walk to the right. Your character stops and a giant tank charges down the hill. You jump on the tank and the battle begins. This boss is not too hard, but is harder than the first boss and it includes a lot of button mashing. Characters that have an advantage include Marco, Ralph, and Eri. Marco's advantage lies in the fact that the Handgun is probably going to be the most used weapon against the boss. Ralph's advantage is that his Vulcan Punch can destroy a part of a boss quickly, allowing you to continue attacking the main body. Eri's advantage lies in the fact that she can throw her grenades upwards to hit the main body with ease. Against this boss, Tarma and Clark have a disadvantage. Tarma's disadvantage lies in the fact that his power lies in the Slug. Since there is no Slug in the boss fight, he has no special abilities. Clark's disadvantage lies in the fact that he cannot use his special technique as there are no organic enemies in the battle for his special to be used on. Fio neither has an advantage or a disadvantage against the boss. While her increased ammo supply ability might be useless as you won't get many special weapons in the battle, the fact that she starts each life with a Heavy Machine Gun cancels that problem. When fighting the boss, the part to aim for is the cannon at the top by shooting upwards while standing under it. To hit it with grenades normally, stand under the cannon and throw a grenade while jumping. Eri does not need to jump as she can throw the grenades upwards. Alternatively, you can stand on the left side and throw the grenade right while jumping. Ultimately, destroying this part destroys the boss and completes the mission. The other destructible parts are not linked to the main health of the boss, but the destruction of them can make the battle easier. By destroying the certain non essential parts of the boss, such as the missiles, you can occasionally get a special weapon such as the Heavy Machine Gun, Rocket Launcher, or a bomb crate. On the first phase, the cannon on top is a large standard cannon. On hard mode, this cannon will shoot large missiles. The missiles fly backwards and will hover in the air. At this point, they are tracking your position. When it drops, it will fall to where you are or previously were if you dodge it successfully. These missiles are destructible and can yield items, but the Handgun does not have enough firepower to take them out quickly enough. Note that this attack is not used easy mode. Another attack the boss uses are small missiles. They come from the side panels of the boss and cross the screen in fixed horizontal linear trajectories. For this attack, I usually stand on the middle right of the boss. Most of them pass over you and they can only hit you if you jump. Occasionally there will be a low missile so jump over it or duck if it looks like it will hit your head and not your feet. These missiles are weak and can be destroyed in two or three pistol shots. Note that this attack can be used at the same time as the homing large missile attack. The third attack the boss uses is two side cannons. The cannons come out of a side panel and rotate from left to right, slowly shooting as they rotate. It is highly recommended to destroy one of the cannons as if you leave both intact, you might get trapped. The cannon I usually destroy is the right one as it is easy to destroy just by standing under it. If you are using Ralph, one Vulcan Punch will take it out and you can continue shooting the boss's main body. When you have done enough damage, the cannon on top will explode and the boss will move to phase two. At this point, the cannon is replaced by a large missile silo. The primary attack of phase two is that a gigantic ballistic missile will launch into the air. While it is launching, a massive amount of flak will go up and slowly fall down. These small shots can be negated by your shots. As the missile goes up, the screen might zoom out a little to show the large missile. The missile will not have enough thrust and soon falls back down towards the tank. When it falls, it will fall to your previous location that is determined when the missile was shot. Note that the missile covers about half of the area so run to the opposite edge of the battle field to avoid attack while avoiding the flak. The large ballistic missile is fired one at a time until the boss reaches its near death state. When you do enough damage to the boss, the boss will be in its near death state. At this point, it fires the ballistic missiles in volleys of two, which makes it harder to dodge. While it is harder to dodge, at least this means the boss is nearly defeated. Shoot it for a little while more and finally the boss will explode and crash into a mountain side. A cut scene follows after the boss that you can watch or skip by pressing start. 7.3 End of Mission 2 Cut scene In my opinion, this cut scene is well placed as it gives you a chance to rest your weary fingers after that button mashing fest on the second boss. After defeating the boss, your character laughs and does his victory pose. In the bush, you will find that General Morden is alive and well and with two Martians. The Martians use their guns and shoot some bondage shot that wraps your character in some thick green rope. Morden laughs his ass off when the Martians suddenly shiver in fear and hug Morden. Suddenly, the Martians shiver in fear and grab onto Morden. Two flying Aliens that you will see in the next levels appear and they grab the Martians. The Martians try to hang on to Morden and they manage to take his pants off, before being carried off by the Aliens. The aliens take a big bite and the Martians hang limp with their brains busted open while the Ailens have a feast on their gray matter. A third flying Alien attacks Morden and knocks him down and he lands at your feet, looking like he is begging for help. At Mordon's base, his men are lifting something up with a crane and they are cheering and laughing. Suddenly the object they are lifting drops and they find themselves under attack by the Aliens. The soldiers try to run for their lives, but they can't get away. The Martians are paralyzed with fear and soon everyone dies and the base explodes. Next, your character breaks free, and Morden looks like he is begging for help while lying on the ground with his pants off. When Morden passes out, the cut scene is over and on to Mission 3! 8.1 Mission 3 At this moment, I do not have this part complete, but I do have a strategy written for the boss of Mission 3 which I will put after this placeholder section. Boss 3 is the hardest and most discussed boss of this game so you are probably more interested in knowing how to defeat him. 8.2 Boss 3 If you are wondering what the boss looks like, he is a giant robot with a brain that you can see through some transparent glass. The boss battle takes place in the sewers of Mission 3. First I will list the character strengths and weaknesses. First off, Marco's advantage his handgun is the powerful and you will be using the handgun a lot. Since you will be using the handgun for most of the battle, the extra damage would help a lot. Fio double extra capacity would be good as any Dual Machine Gun [2xH] you get will last longer. However, I have heard that her hand gun is weaker than normal so with a handgun she might lack the power you need. She also starts each life with a Heavy Machine Gun [H] so that can be used for extra firepower. Tarma is only as good as the Slug which would be a pain to get and reset after you died. Not a good character choice. Eri's strength lies in the fact that her grenades have more range and supply. This is only a good character choice if you can chuck out 20 grenades before you die. Ralph is good because of the second hit. Since special weapons are rare, his half ammo doesn't hurt a lot. Don't try the Vulcan Punch on the boss though as the claws will get you. Clark is completely useless as he can't do his special here and he has no other abilities that would help in the boss fight. Don't choose him. Before the boss battle jump on the Slug Gunner Prototype and fix your Vulcan at about 30 degrees. As the boss walks towards you your Vulcan will constantly hit it. In the beginning, the boss doesn't really shoot much plasma balls so take this time to shoot out your cannon. After doing major damage and when the plasma balls start to rain down, retreat to the middle right side of the screen. If you are about to be hit, suicide the Slug as you are invincible when you jump out of it. The Slug will crash into the boss and you won't need it in the future as getting it back is very difficult. For some players, the Slug can be more of a liability as it is very difficult to retrieve it after you die. After the boss has taken significant damage, he will swing his claws at you when you get close to retrieve the Slug. By the time you manage to get back on the Slug, your respawn invincibility might have worn off and there might not be enough time for you to clear his claws. If you do clear the claws, you will be busy fixing the Vulcan. At that time, you might get hit by a plasma ball and thus you have to repeat the cycle of Slug retrieval while dying quickly. During the battle, the boxis your friend and I tend to stay on top of it at most times as there is enough room to dodge the plasma balls while ensuring you are safe from the car and the electrocution attack. Now I will list some tips on dodging the plasma balls as this is the most common and dangerous attack. What I do is stand on the left middle of the box. When the ball stops moving, it will home on to your present location. When it falls, I tend to jump right and in the middle of the jump, I reverse the joystick and land back on the box. By this time, the plasma ball already exploded and is no longer a threat. In easy mode, the boss will not continuously spam the plasma balls, but use only use it if this is his "turn." If the boss picks up a car, it means free shots as this attack is the least threatening. You can simply avoid it by standing on or behind the box. Watch out for the plasma balls though as they will still be raining down continuously. The boss does not drop the car immediately, but waits a second or so. If he electrocutes the floor, stand on the box and when avoiding the plasma balls, take care not to fall off the box or else you will die from the electrocution. Before the boss electrocutes the floor you can tell he is using this attack as some tubes will come out and face the floor. Also, there will be a box in the area. If he uses the ribbon sinusoidal wave, crouch in front of the box. There is a gap there that will allow the attack to pass you safely. Take care not to camp there too early as a plasma ball will get you. If you have the Slug, dismount/ suicide the Slug and land in front of the box crouching. Note that when you are dismounting off the Slug, you are invincible until you land so you can pass through the attack unharmed. In easy mode, you can dodge this attack by jumping towards the boss while riding the Slug. This tactic does not work in hard mode. When the boss uses the water wave, you have to jump over it. I believe standing on the box will save you but the box will not always be there when he does this attack. This attack is quite rare, but it is perhaps the most difficult attack to dodge. The boss will only swing its claws at you if you try to get close to it after doing significant damage to it. This usually happens if a player tries to retrieve the Slug after they died. This attack cuts the battle field in half and makes the situation quite dangerous. To avoid the melee attack, stay on the right side of the screen so its claws are out of reach. Now to the offensive part. Occasionally, Dual Machine Guns [2xH] will appear. These are quite rare, but they can do massive damage to the boss. Since it is likely you will be dying often, use your grenades to do major damage to the boss every time you respawn. If you are using Eri, range shouldn't be a problem as her grenades travel further than anyone elses. If your grenades tend to miss, you can increase their range by throwing them while jumping from the box. The height of the jump on the box should give your grenade enough range to hit the boss. For the most part, your handgun will probably be used the most. Sneak in a few shots while you are facing the boss when you are dodging the plasma balls. Perhaps the most important part is to throw out all your grenades at the boss as they can do some serious damage. Overall, good luck on beating this boss as this is the boss that most people have trouble on. When you do finally beat the boss, the robot will collapse and its brains will flow out of its head and gush out everywhere. Hopefully this boss guide has helped you defeat this boss.
