Metal Slug Wiki

Metal Slug (メタルスラッグ/Metaru Suraggu), also called Metal Slug 3D to distinguish it from the original Metal Slug, is a run and gun video game for the Sony PlayStation 2. It was developed and published by SNK Playmore and was released in Japan on June 29, 2006. It is the first game of the series to be presented in 3D.

A North American version was planned to be released as "Metal Slug 2006" but it was cancelled. Instead, SNK released Metal Slug Anthology for PS2, PSP, and Wii in Japan, America, and Europe.


From the Metal Slug 3D website:

The tumultuous 2030s.

The world faces a time of chaos due to the waves of military invasions led by General Morden. So far, the dictator General "Devil Rebirth" Morden plots to conquer the world and instigates a series fierce battles by starting coups against the Government Forces, stealing its all-purpose vehicle Metal Slug. He even allied himself with unknown life forms.

But at every turn, thanks to the crack performance of four agents, the pride of the Government Forces, Morden's ambitions were shattered to pieces. Worn down by this series of defeats, the fighting power of Morden's Forces was reduced to mere remnants scattered throughout the world and holdouts in the city of their main base. Morden had been rendered militarily impotent.

But just when everyone in the Government Forces thought Morden neutralized, reports concerning the discovery of hidden Morden Forces from the Division of Intel comes racing across the wires. Word has it that a mid-sized detachment is concealed in a mountain village not too far from the Government Forces' main base. In response to this, GHQ judges the information to be highly credible and directs the special-ops unit Peregrine Falcons to take a second look.

Receiving their marching orders, Marco and Tarma quickly catch a ride on a transport helicopter and head for the site. Tarma optimistically views this as nothing more than another SNAFU. But Marco can't help feeling Morden is once again on the move, because his trigger finger is getting mighty itchy.

Characters & attributes

The four classic characters, Marco Rossi, Fio Germi, Tarma Roving, and Eri Kasamoto, are in the game, as well as their nemesis Donald Morden and Allen O'Neil. New faces include Kewald Oguma (pronounced "Ogma"), who is the president of the technologically leading company named "Oguma Enterprises".

Players are ranked in a mission based on score and time taken. As the player achieves the highest rank, the S rank, on each of the 11 missions, they will receive medals which will increase the respective characters' combat abilities. Reaching S Rank in all missions gives the 12th medal. The combat ability is broken down into four different categories: Pellet/Power/Hit Rate/Machine. There are four levels for these combat abilities. The higher the level, the more effective their skill becomes.

  • Pellet determines the "splash" damage caused by the character's weapon. As the skill grows, the damage radius of their weapon will also increase. Eri starts with the Pellet stat maxed out.
  • Power determines the amount of damage caused by the character's weapon. As the skill grows, the total damage done by their weapon will also increase. Fio starts with the Power stat maxed out. 
  • Hit Rate determines the accuracy of the character's weapon. As the skill grows, the overall accuracy of ranged weapons used by the character against enemies will increase. Marco starts with the Hit Rate maxed out.
  • Machine determines the vehicle handling. As the skill grows, characters will be able to handle their vehicles more easily. Tarma starts with the Machine stat maxed out.

Aside from combat abilities, there also are four upgrades that the player can purchase using the skill point' gathered by playing the game. Playing the game on harder modes give the players more skill points which translates into faster upgrades. The upgrades are: Lock Range/Life Up/Luck/Rapid Bomb. Each of these upgrades cost 2000 skill points.

  • Lock Range increases the distance in which the player can lock on the enemies.
  • Life Up increases the character's health by one hitpoint.
  • Luck makes enemy weapons less accurate against the player's character.
  • Rapid Bomb decreases the character's rate-of-throw for secondary weapons.


In the Garage, players will be able to access various sections, including Soldiers, Main Weapon, Sub Weapon, Slug Customize, Laboratory.

  • Soldiers section lets the player switch between characters to be played on the next mission. Note that each character has their own paths, objectives, and enemies to face.
  • Main Weapon displays the current primary weapons and respective ammunition the player has in their in inventory.
  • Sub Weapon serves the same purpose as the Main Weapon section but with grenade-type weaponry.
  • Slug Customize lets the player customize the Slug with various parts built in the Laboratory.
  • Laboratory is where the player uses their materials to build different parts of the Slug

Custom Super Vehicle parts

There are five different categories in which the player can modify the Metal Slug with: Core, Caterpillar, Cannon, Vulcan, and Armor. Parts are acquired by collecting CDs found in the missions and then using the required amount of materials to build it.

Core is the Slug's chassis. Each chassis is able to support different types of equipment.

  • Normal Core is the standard chassis.
  • Powered Core allows the Slug to mount various Cannon parts otherwise unusable with other two cores.
  • Gunner Core is the chassis required to unlock the Slug Gunner.

Caterpillar is the Slug's treads.

  • Normal Caterpillar are the standard treads.
  • Speed Master are slightly faster than the standard treads.
  • Agile Caterpillar is slightly faster than the Speed Master.
  • Hovering Type is not as fast as caterpillars, but offers better stability.
  • Splitter is not as fast as other caterpillars, but does more damage to things the Slug runs over with it.
  • Gunner Legs are the treads required to unlock the Slug Gunner. It is also the fastest among the caterpillars.

Cannon is the Slug's primary weapon limited in ammunition.

  • Slug Cannon is the standard main gun. It has an arc trajectory meaning that it is useful as a "splash-damage" weapon but not precision weapon.
  • Flamethrower spews out a short stream of fire that deals great damage to anything in its way.
  • Homing Missile tracks in on target, and after approaching the target explodes and releases a number of smaller cluster missiles that swarm over nearby target(s).
  • Pile Bunker is a huge, sharp ramming tool that will not only damage anything directly in front of it, but out to a certain range because of the shockwave generated from it. It seems to impale anything that touches the weapon itself.
  • Rail Gun is a long cannon that can be used as a "sniper" weapon for the Slug. Although not very powerful, it has great range and respectable rate-of-fire.
  • Large Missile is the long-range quadruple rocket launcher mounted on one of the enemies, namely the M-15A Bradley. When fired, it will launch four big, unguided (unless one locks-on) rockets in succession. While each rocket do not inflict a lot of damage, the combined firepower of all four rockets hitting their target is devastating.
  • Parachute Bomb fires a long-range mortar useful for enemies that are hiding behind cover, but is useless in environments where there are objects that might block the projectile overhead (for example; ceilings and overpass signs).
  • Gunner Cannon is the cannon required to unlock the Slug Gunner. It is also the most powerful cannon that the player can equip on the vehicle, although its utility is greatly hampered by the fact that the turret does not rotate to track the target and the shell has very flat trajectory.

Vulcan is the Slug's secondary weapon. They do not cause much damage as the primary weapon, but they do have unlimited ammunition.

  • Normal Vulcan is the standard gun. It is relatively accurate and has the ability to engage aircraft, but can only move its barrels vertically and not horizontally, thus not being suited for engaging multiple enemies at once.
  • Wide-range Vulcan is the exact opposite of the standard Vulcan. Its barrels can only move horizontally but not vertically, making it suitable for engaging multiple ground enemies but not for engaging enemies at an elevation or aircraft.
  • Multirange Vulcan can traverse its barrels in all directions, making it excellent for utilizing "circle of death" tactics on a wide, open field.
  • Gatling Gun has same characteristics of the standard gun when it comes to target tracking, but it fires more munitions in a wider area, making it perfect for engaging and destroying a number of foes at once.
  • Napalm is a pair of mortars that fires off balls of Napalm in an arc trajectory. It is very powerful, but the travel time of the projectile is slow, and decreases significantly as the target is further away. The area-effect of this weapon is, however, quite impressive.
  • Gunner Arms is the gun required to unlock the Slug Gunner. When mounted on a normal Slug, it is basically a pair of Pile Bunkers with unlimited ammunition. When combined with all other parts necessary to unlock the Slug Gunner, the weapon turns into a Vulcan and a Pile Bunker.

Armor determines the type of protection the Slug gets. Excluding the basic armor, all armors are add-ons to the basic armor. The add-on armors will only protect the vehicle from certain type of projectiles, and the basic armor will be responsible for "dishing-in" the damage received from all other projectiles. When the basic armor is gone, the Slug will explode. As for the add-on armor, it can take certain amount of hits before being rendered completely useless, leaving the vehicle unprotected after that.

  • Normal Armor is the Slug's basic armor. It offers basic protection against all types of projectiles.
  • Fire Resist Armor has limited ability to prevent the vehicle from being damaged by incendiary weapons.
  • Sloping Armor has limited ability to protect the vehicle from being damaged by projectile weapons.
  • Reactive Armor offers limited protection against all forms of explosive-based weapons, including rockets, missiles, grenades, bombs, anti-tank shells, and so on.
  • Tempered Shield is the Melty Honey's shield. It offers limited frontal protection only against all forms of projectiles
  • Physical Armor protects the vehicle from being damaged by energy weapons.


Primary Weapons

Unless stated, all weapons have the ability to automatically track in on their target using the track button (R1) on the joypad.

  • Tonfa as melee weapon for Fio and Eri.
  • Handgun as the standard ranged weapon. Does very little damage and has short range but has unlimited ammo.
  • Heavy Machine Gun is a machine-pistol firing rifle-caliber munitions and has medium range and high accuracy.
  • Double Machine Gun consists of two machine-pistol firing pistol-caliber munitions. While the firepower of each gun is decreased by a fraction, the combined firepower of the two guns make them slightly more powerful than the Heavy Machine Gun.
  • Rocket Launcher fires an unguided rocket at the target. Although the rockets travel slowly, they are quite powerful for their availability. Aiming is done manually.
  • Super Grenade is basically a grenade launcher mounted on a rifle. (the rifle is never used, however) Although the travel time is slow, the grenade does devastating amount of damage. Aiming is done manually.
  • Enemy Chaser launches homing missiles. Although weak, it has quite fast rate-of-fire.
  • Flame Shot shoots a continuous stream of flame. Deals fair amount of damage but has very short range and runs out of ammunition quickly.
  • Iron Lizard fires a remote vehicle filled with explosive gas. The vehicle is unguided but can climb up some terrain and walls.
  • Laser Gun fires a continuous beam of highly concentrated light that does tremendous amount of damage over a tiny area. Runs out of ammunition very quickly. Aiming is done manually.
  • Shotgun fires pellet rounds that are very powerful in close range.
  • Sniper Rifle does fair amount of damage and has an extreme projectile range. A scope is provided. Aiming is done manually.

Secondary Weapons

Grenades are thrown by hand. Although their range is short, they offer better firepower than most side arms.

  • Grenade is a regular stick grenade, better known as the Stielhandgranate.
  • Fire Bomb is a Molotov Cocktail effective against infantry.
  • Stone is only effective against infantry in this games, unlike in other games where stones were highly effective against all forms of targets.
  • Smoke Bomb can conceal the player, as well as the enemy, for a short duration. When used by the player, the enemy will stop shooting until the smoke clears and get better view.
  • Monolith is basically a beacon for the gigantic stone tablets used by the Monoeye UFO during the second level of Metal Slug 3. When thrown, a harmless beam of light will shoot down from the sky, and in less than a second a huge stone tablet will drop down on where the beam was pointed at causing extreme amount of damage that is unparalleled by any other weapons in the game. The stone tablet does not damage the player, however, and it is safe to run into middle of it.


Upon completing the game once, the player receives the Monolith grenade as an unlockable.

The Slug Gunner is unlockable by obtaining all the required parts and assembling it. Removing one part reverts it to the SV-001.


  • The game had no definite title when it was first unveiled in Tokyo Game Show back in 2004. In Electronic Entertainment Expo of 2005, SNK Playmore has revealed the game to be called "Metal Slug: Evolution". However, this was later changed to just being "Metal Slug". It is called "メタルスラッグ3D" or simply "メタルスラッグ" in Japanese. In Metal Slug Attack, it is referred to as Metal Slug (3D).
  • Although only released in Japan, it contains a menu that is written mostly in English, as well as American voice acting. Japanese subtitles and dialogues are present for non-English speakers. There are unused, near-complete English, Spanish, French, German, and Italian translations in the game, and these can be accessed by patching the game with the associated cheat.
