At its core, WeaponLord is a standard 2D fighting game experience. Where it differs is in its gameplay mechanics, and in some of its aesthetic choices and presentation. The game features thrust-blocking, an aggressive blocking system similar to Street Fighter III's parry System. Also introduced in the game are Deflect moves, a counterattack maneuver that each character has. Certain special moves, known as "Take Downs" knock opponents onto their back. A player can then follow up with additional attacks while their foe is still on the floor.
In addition, when certain attacks are performed on an opponent in mid-swing, the player can cut off a piece of their clothing or their hair. Players can finish off matches using "Death Combos" combination attacks that can have a gory effect on opponents.
WeaponLord's fighters possess between 9-12 special moves each. Moves can be executed one of several ways: sweeping motions on the directional pad followed by an attack button, "charge" moves where a directional button is held for 2 seconds quickly followed by the opposite direction, and finally an attack button, or hold down moves where the player must first hold down an attack button, followed by a directional motion, and finish it by releasing said attack button.
