Eri with heavy machine gun

The Heavy Machine Gun (HMG) is the main special weapon in the Metal Slug series. 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 using a continue. The exception being Metal Slug's third mission when fighting the Tani Oh which gives out a Rocket Launcher instead.

In Metal Slug 6 and Metal Slug 7, Fio Germi starts with a Heavy Machine Gun in her weapon stock. In Easy mode, all characters replace their pistols with an infinite HMG, with Fio holding the Big version. All prisoners who normally gave out HMGs will give bomb ammo instead.

In Metal Slug Attack, units who collect an HMG crate on the field gain a temporary attack boost. Rumi Aikawa, Sisilia (both variants), Rootmars X, and other support units are able to produce HMG crates, and only their teammates can collect them.


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

Marco draws his HMG (which resembles Allen's HMG, the M60) and shoots at the foe. The move is fast and has a medium range but cannot be chained.
