Boss Rush Mode is an alternate mode first introduced in Castlevania: Harmony of Dissonance and then reused in some later games. It is accessible once the game is completed (some require the "best ending" to be received) or by killing all bosses.
In this special game mode, the player must defeat several bosses from the game, one after the other. The player is usually presented with three courses at the beginning, each having a different level of difficulty. Upon completion of each course and depending if the player met certain criteria at the end (like finishing the course in a set amount of time), rare and powerful items can usually be obtained as a reward. The mode's progress defers from game to game.
Boss Rush Mode is unlocked once the game has been completed. It is played with Juste Belmont by default, no matter which ending was obtained. There are time trials in this mode in which the player can obtain rare and/or unique items at the end if the requirements were successfully satisfied. It is possible to collect Hearts between each boss room, but it's not possible to change the player's sub-weapon as it is chosen at the beginning of the Rush.
Maxim Kischine can be selected by pressing L + R while choosing the difficulty level. Another character only accessible in this mode is Simon Belmont, who can be unlocked if the Konami Code is used (↑, ↑, ↓, ↓, ←, →, ←, →, B, A, Select). An arrangement of Vampire Killer and Clockwork can be heard when playing as him.
Three Boss Rush "roads" are open for the player, each one being more difficult and longer than the last, and being unlocked by finishing the precedent one. The Normal road contains bosses from the Easy Road, and the Hard one contains all bosses from the game.
The mode can be unlocked if the player receives the best ending (by equipping the Flame Demon's, Giant Bat's and Succubus's souls when dealing the last blow to Graham's first form, and then entering the Chaotic Realm to destroy Chaos). Once the best ending is achieved, the player may go to the starting screen and select "Extras", where Boss Rush Mode is available. Man-Eater is oddly a boss in this mode too, as it's normally just a regular enemy. This mode can also be played as Julius Belmont if the player finished and saved a game as him.

Boss Rush Mode is unlocked when all the bosses have been defeated, including Legion and Nuculais. Boss Rush Mode can be entered during the game via warp rooms. It also allows the player to steal and obtain materials that they weren't able to obtain the first time around. Note that while playing as Trevor, Boss Rush Mode would be more challenging as Trevor does not use restorative items. Beating the Boss Rush Mode unlocks the Sound Mode.

This game's Boss Rush mode is different from the previous incarnations of the mode in the series - it becomes available as soon as one boss is defeated, it can be played with the help of a friend via a cooperation mode, and it is split into four courses; Random Rush, Boss Rush Normal, Boss Rush Dash, and Full Boss Rush. The player can choose between Richter Belmont and Maria Renard before starting this mode. Interestingly, Maria Renard is available once this mode is unlocked, even if she is not yet rescued in the main story. This allows the player to test her even after the first level of the game.
The player is goes through rooms filled with several candles, vases, and other breakable objects which contain Hearts, and various Sub-Weapons, Meaning, every room serves as a breather before each boss fight. Once ready, the portal in the center of the room can be entered, in order to proceed to the next boss fight.
- In Random Rush, the player will have to face all the bosses they have defeated so far in a random order. Because it is the only course that can be played as soon as at least one boss is defeated in the normal game, it is also the only course that doesn't give any reward for completing it.
- Boss Rush Normal contains all of the normal bosses of the game. However, Dracula is not fought in this course, and Shaft doesn't summon any monsters.
- Lesser Vampire
- Boss Rush Dash contains all of the alternate bosses. Once again, neither Dracula or any of the bosses Shaft summons in Level 6 are fought.
- Bone Golem
- Carmilla and Laura
- Shaft's Ghost.
- Full Boss Rush contains all of the bosses in the game, this time including Dracula.
The three last courses give out three rewards each. With the exception of Akumajyo Dracula Peke (unlocked after completing Boss Rush Normal three times), these rewards are always Sound Items.
This mode is unlocked after Dracula's defeat. You can play through it with either Shanoa or Albus. Two courses can be done: the first one contains every boss fought before getting into Dracula's Castle (an exception is the Giant Skeleton) and the second one that contains every boss fought inside Dracula's Castle (an exception is the Wallman).
- Course A
- Course B
The rewards are the following:
- Less than 4 minutes: L. Eye of God or R. Eye of Devil.
- 4 minutes or higher: Arrow Helm, Axe Helm, Hammer Helm, Knife Helm, Lance Helm, Rapier Helm, Shield Helm, Sickle Helm or Sword Helm.
This mode only appears in the HD remaster of the game. It is unlocked after the player finishes the game for the first time (a 100% run isn't mandatory). The player has access to all the unlocked techniques and upgrades from the Story Mode, even those obtained by defeating a specific boss (i.e. Alucard's Demonic Wings from the Daemon Lord). All bosses are fought, at the exception of the Daemon Lord with Trevor Belmont, as this boss is a quick-time-event sequence. If defeated, Dracula will make fun of the player's capacities.
- Night Watchman
- Daemon Lord (resurrected)
- Dracula (Alucard and CPU Simon)
- Executioner (1)
- Lady of the Crypt (no quick-time-events)
- Executioner (2)
- Dracula (Trevor only)
