Bosses

There are eight bosses and twelve minibosses in 30XX. Each stage has its own miniboss and end boss - unlike 20XX, levels are not shared between bosses. Gauntlets also feature 4 different minibosses, each corresponding to a Resonant Armor Piece.

Minibosses
Minibosses appear before the end boss of the level. Unlike bosses, minibosses do not have a bossbar.

Bosses
Bosses are strong enemies that appear at the end of a level. They must be defeated to proceed. Defeating a boss lets you take its power. Memoria can also be collected after defeating the boss. Defeating any boss after Level 3 will also give you a choice between collecting the Power, a Power Aug/Remnant Aug, or nuts.
