Eri with heavy machine gun
The Heavy Machine Gun is the main secondary weapon in Metal Slug. It is represented by the icon H.


These crates are easy to find and the 7.62mm FMJ rounds in them fits most of the automatic weapons utilized on the battlefield. It has the same firepower as a regular handgun, but its high fire ratio compensates for it, turning this weapon into one of the deadliest of all.

It is also very common compared to the other weapon pickups, and appears whenever a character restarts after they have lost 1 credit, except in Metal Slug mission 3 when fighting Tani Oh.

In Metal Slug 6 and Metal Slug 7, Fio Germi starts with a heavy machine gun (in Easy mode she has the upgraded version). In Easy mode, all characters have an infinite supply of Heavy Machine Gun, and all prisoners who give out HMGs will give bomb ammo instead.


A Heavy Machine Gun normally has 200 ammo from Metal Slug to Metal Slug 5.

Heavy Machine Gun
Marco draws his HMG (which resembles Allen's HMG, the M60E3) and shoots at the foe. The move is fast and has a medium range, but cannot be chained.
