Hardmode

Hardmode is a new character type released after Overworld's End. You can choose between a normal character or a hardmode one. It is essentially a harder version of all levels. All secret missions (as well as the tower, daily trials, and Gauntlet of Gales) are not affected by this mode.

## Story

This takes place in an alternate universe where the Orb of Dominance got way stronger when Archie got it and it actually looks like an orb (and not a cube). Also in this universe, the Nameless One was extremely powerful, and so were all other manifestations. The Undertale characters do not forgive you for killing off all the mobs, creating something similar to the genocide route.

## Difficulty

There are 7 levels of hardmode, and each hardmode mission is assigned to a level. Orb Clan Fortress has a special level known as Level X.

## Special gear

Each level has a new gear piece and artifact that can only be found at that level on hardmode (except for Obsidian Pinnacle, Broken Citadel, and Orb Clan Fortress which have 4, and the towers in Overworld's End which have no new gear pieces).
