Boss Rush Mode is a mode first introduced in 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 bosses from the game. The mode's progress defers from game to game.
Appearance in Harmony of DissonanceEdit
Boss Rush Mode is unlocked once the game has been completed and is normally played with Juste Belmont. There are difficulty time trials in this mode, and you can play as Maxim Kischine by pressing L + R while choosing the difficulty. Another character only accessible in this mode is Simon Belmont, who can be unlocked if the Konami Code (Up, Up, Down, Down, Left, Right, Left, Right, B, A, Select) is used.
Appearance in Aria of SorrowEdit
The mode can be unlocked if you receive the best ending (use Flame Demon, Giant Bat, and Succubus soul when fighting Graham and then kill Chaos). Once the Best Ending is received, go to the starting screen and select extras, and Boss Rush Mode is played. Man Eater is oddly a boss in this mode. (it is normally just a regular enemy)
Appearance in Lament of InnocenceEdit
Boss Rush Mode is unlocked once all bosses are defeated (including the Elementals and the Forgotten One). It then appears in the Castle Entrance as a sixth portal.
Appearance in Dawn of SorrowEdit
Appearance in Curse of DarknessEdit
Boss Rush Mode is unlocked when all the bosses have been defeated, including Legion and Nucleaus. Boss Rush Mode can be entered during the game via warp rooms. It also allows the player to grab materials that they weren't able to obtain the first time around. Note that playing while playing as Trevor, Boss Rush Mode would be more challenging as Trevor does not use restorative items.
Appearance in Dracula X ChroniclesEdit
This game's Boss Rush mode is different from the previous games 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.
- 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 felled 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 : Wyvern, Werewolf, Minotaur, Dullahan, Death, Shaft, and the Lesser Vampire. Dracula is not fought in this course, and Shaft doesn't summon any monsters.
- Boss Rush Dash contains all of the alternate bosses : Serpent, Bone Golem, Dogether, Carmilla and Laura, Shaft, Hydra, and Shaft's Ghost. Once again, neither Dracula or any of the bosses Shaft summons in Level 6 are fought.
- 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.
Appearance in Order of EcclesiaEdit
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).
