• Playable Character Classes Discover, unlock, and play as different characters including some favorites from UnderMine. Each playable character has unique stats, abilities, upgrades, and relics they can find. Each character significantly alters the feel of the game.
• Branching Paths New regions of the Undermine have been revealed, and each branches off into various other areas. Navigate it to complete builds, quests, and different objectives. Your final challenge depends entirely on your decisions throughout the run.
• Arcana Wield new, interactive relics called Arcana. Each adds a new ability to your character, from casting fireballs to summoning skeleton minions to rearranging time and space. Arcana can make an old character feel new by centering entire builds around their function.
• Full Mod and Workshop Support We’re shipping you the tools we use to make the game and making it as easy as possible to upload and download mods from Steam Workshop. We feel we’ve created a really great technical platform and are excited to share that with you.

The Crone Valeen and Hexes

• Serious players require even more serious challenges. Now, after completing their first run, the player will unlock Valeen, the Crone. Valeen then joins the hub and the Othermine antechamber. The player can ask Valeen to hex them, which will apply powerful debuffs that can not be removed during a run. Hexes seriously alter a run and can be stacked on top of each other for additional challenge.

Journal Improvements

Fully Expanded Map

Hoodie’s Care Package

Steam Trading Cards

Achievement Changes

• We have changed the conditions by which players can earn the 5 “No Upgrades” boss achievements. Now, you simply need to defeat the 5 major bosses while using the “Rogue’s Ultimatum” hex, which is functionally the same as having no upgrades. This is to alleviate a lot of confusion around what constitutes an “upgrade” and to avoid the necessity to start a new save file. Please note: If you had previously earned these achievements under the old rules, you will still have them and do not need to earn them again.
