What's new

Super Weapons

The boxes were increased with the known weapons in Metal Slug and Metal Slug 2 but with a more powerful level, either in range, damage, etc. in the obese transformation they change their attack form, in the case of the Rocket Launcher it is the only one that does not present any physical change they become dirigibles like the Enemy Chaser taking slow trajectory.


A powerful weapon against armor, increases its power when the player gets fat (they turn into rocks)

Iron Lizard

It is a new weapon in this game. This weapon launches a kind of caninomorphic missile and crawls on the ground to explode in an enemy target. In fat mode, these missiles turn into yellow spheres with legs.

Enemy Chaser

Small missiles similar to the "Rocket Launcher", but they differ in size and in that the first pursues the enemy. They also differ, since the Rocket Launcher is more powerful, although less precise. When you are obese, you acquire the power of a normal grenade. Clear example of this is the first segment of Mission 5 of Metal Slug 3, the same case in Metal Slug 5 Mission 2 and Metal Slug 6 Mission 4, when you are flying.

Super Grenade

It has similar functions to the "armor piercing" (A.P.), so it can kill a large number of soldiers and aliens. As the name suggests, they are more powerful than ordinary grenades however it is one of the rarest weapons to get, it appears only in mission 5 in the subway area, in later titles it is found very rarely with less frequency, in its obese form, the grenades become larger and with greater power.

Drop Shot

The drop shot is also a new weapon in this game. The weapon has like ammunition a species of explosive balls that when being fired they bounce. It is not very good for long-range attacks, in its obese form the explosive balls become large, its explosion is more important.


  • "Camel Slug": The ammunition changes in appearance becoming bigger (acquiring the shape of a Heavy Machine Gun Augmented in fat state), although they still have the same power.
  • "SlugNoid": When used in Mission 5, the cannon acquires the power and characteristics of a Flame Bomb in an obese state, as long as the plane of explosion is located on the ground.
  • "Metal Slug Type-R": Varies the coloration of the tank in Mission 3, acquiring a sunset orange tone, which will persist in certain situations throughout the saga (such as Mission 1 of Metal Slug 3, against the boss) . The only difference with the common tank is that this model can reach greater height when jumping, as well as this vehicle is faster in the first delivery (Metal Slug).
  • "Slug Flyer": No change at all (only slight control improvements to obtain a more accurate flight) Based on the real Bae Harrier GR MK 3 model (VSTOL ground attack aircraft).
