The game opens with a playable prologue featuring Richter Belmont's final battle against Dracula from Castlevania: Rondo of Blood. This serves as a tutorial for basic combat and movement. You are intentionally overpowered here, so don't worry about dying.
Objective: Defeat Dracula
As Richter, you have access to the Vampire Killer whip, a powerful sub-weapon (Holy Water), and item crashes. Focus on learning the attack patterns. Dracula will teleport around the arena, summoning fireballs and bats. Use your whip and Holy Water to deal damage. After his first form is defeated, he transforms into a larger, more demonic form. Continue to attack relentlessly. This fight is largely cinematic and designed to set the stage for Alucard's journey. Once Dracula is defeated, the true game begins.
