Hydlide 3 - Yami Kara no Houmonsha (Japan) is a continuation of the Hydlide series. The game remained in the action RPG genre for the NES.  It builds on established elements of the previous Hydlide games, although specific details about its plot and gameplay mechanics aren't widely available in English.  It's likely that this entry still offers an open world or semi-open world design along with sword combat, magic, and possibly expanded lore within the Hydlide universe.  Being a Japanese-only release, details are more scarce.
