Boss Rush

**Boss Rush** is an optional game mode where the player fights all bosses in sequence though some games make them compulsory.

## Lunar Shadow

Lunar Shadow has no Boss Rush Mode because there isn't any space for more maps. King (2.0) tried to add one in in his copy of the mod, but after finding it to be frustrating decided to turn the entire copy into Lunar Shadow~The Gauntlet.

## Solar Shadow 2

Splendid Tower makes you fight 4 minibosses. After a breather, and a Save Point in Sky Platform, the player must fight 4 harder versions of them, before they can fight Nought Celeritas:

* Gold Knight
* Gold Witch
* Gold Thug
* Gold Demon
* Platinum Knight
* Platinum Witch
* Platinum Thug
* Platinum Demon

## Umbrageous Light

Umbrageous Light has no Boss Rush Mode because it's early in development and only the first area is mostly complete.

## Apocalyptic Shadow

Apocalyptic Shadow has no Boss Rush Mode because there isn't any space for more maps.

## Gun

Gun will have a Boss Rush Mode implemented after Gun v4.Unlike the main game, the player can choose a single weapon (either Boss or non-Boss Weapon) or a Boss Weapon or non-boss weapon to take into battle; the only time you can change your setup is between battles.

It will be the last feature that the player unlocks and is split into three difficulties:

### Mechanto Arena

You fight all the story mode bosses and an optional boss. The HP orbs during the first three boss fights and the full heal before the final boss is removed, though the Healing Machine between battles fully restores HP and there's also a EXP Capsule that gives 100 EXP. Completing the Mechanto Arena once unlocks the Mechanto Arena X.

After defeating Big Boy, the player is returned to the rest area but it's now nighttime rather the daytime it was previously. The player must then do battle with the last 4 bosses before completing the Mechanto Arena.

* War Machine
* Diamond Dogs
* Big Boy
* ???? (optional boss)
* ????
* ????
* ???? (final boss)

### Mechanto Arena X

You fight all the optional bosses, Mechanto Mode's final boss and the true final boss. There are no HP Orbs during boss fights and the EXP Capsule only gives out 50 EXP.

The player starts outside of a post-apocalyptic version of Mechanto Isles, the place broken down with a hellish red sky. After defeating the first 6 bosses, the player is now inside with the music changing to a mournful drone. You will need to defeat the Final Four in order to complete the Mechanto Arena X.

* Taboo-Oh
* Taboo-Me
* Taboo-Ga
* ???? (Mechanto Mode EX boss)
* ???? (warp portal EX boss 1)
* ???? (warp portal EX boss 2)
* ???? LAST 4
* ???? (Mechanto Mode final boss) LAST 3
* ???? LAST 2
* ???? (true final boss) LAST 1

## The Ultimate Challenge

After completing Mechanto Arena X, there is one last challenge to do before Gun can be considered truly done.The player fights both sets of bosses from the Mechanto Arena and Mechanto Arena X with no rests inbetween fights, and the player is only allowed to use one weapon. However, this weapon is the same one used to unlock Ending 03: Glory to Mechanto, allowing the player to make short work of each boss.

After sending all the bosses from the Mechanto Arena to the scrapyard, the player will be fully healed before they go on to brutally crush all of the bosses from Mechanto Arena X.

## Trivia

* Gun's boss rush mode is based off the Kirby style boss rush (The Arena and The True Arena), right down to the True Final Boss being a "Soul" version of the final boss. Furthermore, much like Kirby Super Star Ultra's True Arena, it has exactly 10 bosses and follows its structure.
* Due to Lunar Shadow ~ The Gauntlet sharing the same developer as Gun, it's no surprise that it shares the same basic formula. However due to being based off a modified version used for his game concepts, it has 4 Arena types instead of the 2 seen in Kirby. These types are **Bronze** (story mode bosses), **Silver** (EX Bosses and the True Final Boss of the main game), **Gold** (Strongest versions of story mode bosses and bosses exclusive to the game's "Extra Mode" with a "Soul" boss at the end) and **Platinum** (Special Bosses who are the hardest fights in the game).
