Not only was Castlevania: Symphony of the Night the first installment of the Castlevania series on PSX but also the first PSX game to have a published run here.
Not satisfied with just going on a death spree to Dracula, Alucard decides to steal every single one of his father's heirlooms, while also killing his prized collection of monsters. Luckily he has the handy ability of phasing through walls whenever he needs to.
A run that beats the game through save data corruption is available here, along with one that avoids data corruption. If you prefer the main character to have muscular bare arms and to pray to the rain gods to defeat bosses, you may enjoy the Richter version. If you want to see a run on Replay mode that can skip many cutscenes, see this run. We also have a run of the Saturn version using Maria. We even have a run where Alucard avoids killing everything except Dracula.
Due to the lengthy amount of time needed to obtain the best ending in the previous run, this run was deemed significantly more entertaining, and thus obsoletes it.
Note: Due to an emulation error, the audio in the ending FMV sequence doesn't play.
