Used since the first Great War, then being banned by the U.N. convention, then being used again, the flamethrowers are effective against infantry and lightly armored vehicles at close range. One shot is enough to burn a number of soldiers, and a few are enough to melt vehicles with ease.
There are two versions of the Flame Shot. The first version only appears in the first Metal Slug game, shooting a fireball that covered a good range but was quite weak. The second version replaces the previous one from Metal Slug 2 onward, shooting a stream of fire that covers a lesser range but causes more damage to vehicles. A variation called the "Big Flame Shot" shoots a larger stream of fire that covers more range, burns more enemies, and causes even more damage to vehicles.
When a character turns fat, the Big Flame Shot becomes even more powerful, firing a giant fireball (unlike one in Metal Slug 1).
A Flame Shot gives out 30 ammo from Metal Slug to Metal Slug 4.

- Due to rushing the game, the Flame Shot was scrapped and unused in Metal Slug 5. Despite this the game has burning animations for the most common enemies. These unused sprites from Metal Slug 5 were used in Metal Slug Defense instead.
