The castle flipped upside down, the game doubled in size, and a genre was born.
Koji Igarashi's masterwork combined Castlevania's gothic action with Metroid-style exploration and RPG progression. As Alucard, Dracula's son, players explored a massive castle filled with secrets, equipment, and abilities that opened new paths. Just when you thought you had finished the game, the entire castle inverted, revealing an equally massive upside-down version with new enemies and bosses. The RPG systems, including leveling, equipment, familiars, and spells, added incredible depth. Despite being a 2D game in the early 3D era, it became a beloved classic.
Example
The inverted castle reveal is one of gaming's greatest surprises. Players who defeated Richter normally got the 'bad' ending. Finding the holy glasses revealed that Richter was being controlled, opening the upside-down castle and roughly doubling the game's content. Many players had no idea this existed.
Why it matters
Symphony of the Night formalized the Metroidvania genre alongside Super Metroid, merging exploration-based progression with RPG systems. Its influence on indie gaming is immeasurable. Hollow Knight, Dead Cells, Blasphemous, and countless others descend directly from this game's design philosophy.
