The Zantetsu Sword is a special weapon introduced in Metal Slug 6. It is represented by the icon 021445.gif.


The Zantetsu Sword is a knife (or hatchet) that imbues the holder's melee attack with large waves of energy, powerful enough to destroy armored vehicles. It can cut through the enemy's bullets and weaponry, at the cost of a low ammo count, so use it wisely.

Unlike other special weapons, the Zantetsu Sword can only be fired sideways.

In Metal Slug Attack, the Special Forces soldiers have their own version called the Sky Splitting Sword. The energy wave has a shorter travel than the Zantetsu Sword.
