Sword Master is a side-scrolling action game developed for the Nintendo Entertainment System. The game is set in medieval fantasy setting and focuses primarily on strategic fighting using shield and sword.
Sword Master is a side-scrolling action game in which the player must use sword and shield to battle through 7 game levels, from the forest, to a cursed town, to multiple levels of the villain's castle lair. The player encounters giant bats, wolves, skeleton warriors, evil knights, wizards, lizard men, gargoyles, and other fierce enemies on his quest. The Sword Master can swing his sword, defend with his shield, and gather power-ups which enable him to change his form. For example, the Sword Master can transform into a mage and cast offensive magic spells.
