In the 11th century, when monarchies weakened, local feudal lords grew stronger. The first knights simply protected their lord's domains, but with the reforms of late 11th century, knights also protected the peace. They fought against heretics for God. One company of knights was said to be invincible due to two men: Leon Belmont, a baron who feared nothing and whose combat skills were second to none. And his friend Mathias Cronqvist, a genius tactician whose education made him an exception, in a largely illiterate society. They trusted each other completely and had a long friendship together. But one day, as Mathias returned from a victorious campaign, he received news of the sudden death of his wife, Elisabetha. His grief was profound and he became bedridden. A year passed since then, and because of Leon's efforts, the company stayed undefeated. However, an army of monsters suddenly appeared in Leon's domain. Because of the Crusades in the East, the Church was only interested in fighting heretics, instead of monsters. It was forbidden to fight unauthorized battles, so Leon wanted permission to retaliate, but the Church denied his request. One night, Mathias struggled from his bed. He told Leon that the monsters were related to a vampire who lived in a castle of the forest, 'Eternal Night'. Mathias said that Leon's betrothed, Sara Trantoul, was kidnapped by this vampire and brought to his castle. Many game mechanics and elements in Lament of Innocence are taken from the metroidvania style, from the currency, items, upgrades and map style. However, the Experience Points and Level-Up mechanics are not present in this game. The main character's weapons are also limited to the whip, sub-weapons and relics. As the player progresses through the game, defeats specific enemies, or perform repeated actions, Leon will gain additional abilities, or combos that are signified by a message prompt (e.g. Guarding against 15 enemy attacks will unlock Perfect Guard). Relics and Orbs are likewise the most significant items that the player must find. Several HP, MP, or Heart Upgrades can also be found throughout the castle. Many areas also contain secret parts, puzzles, or numerous environmental traps. From the back of the box: Leon Belmont, an eleventh-century nobleman and knight of clergy, is about to be wed when his fiancee, Sara Trantoul, suddenly disappears. Leon embarks on an epic journey to bring her back, unaware that a growing evil looms like a shadow over his quest. The majestic tale of Castlevania and the true origins of the Belmont clan of vampire-hunters is about to unfold.
