UnderMine 2 is a retro-inspired dungeon crawler from developer Thorium released on Steam in August 2025. The game is still in early access, but now has a major update, titled Dustfall, that will “test you like never before”, according to the developer. A new vlog, released to showcase the update, gives plenty of insight into what fans can expect when they next head out on an adventure.
The main content additions to UnderMine 2 are new areas, such as the Duskfall starting location and the Thimble Ticket market. There is also a new difficulty mode named The Grim Crucible, a combination of UnderMine’s Summoning Stone and Hades’ Heat. And to round things out, a new boss fight with the powerful Bul & Gogi.
Key features in UnderMine 2:
A Band of Hopeful Heroes: Discover, unlock, and play as new characters such as the lucky and ambitious Black Rabbit, or the dark and brooding Inquisitor Danté. The trusty Peasant is, of course, still an option. Each character has unique upgrades, abilities, and interactions, making for a fresh experience every run.
Embrace Endless Challenge: The Well, a never-ending challenge, awaits you at the bottom of the Undermine. Powerful enemies and bosses will test your skills and build. Discover its unique challenges, plan your run to overcome them, and see how far you can truly delve in this highly replayable adventure.
Harness the Power of Arcana: Wield new, interactive relics called Arcana. Each adds new abilities to your character. Leave your regular, basic abilities at the door, and form unique builds around devastating meteor barrages, sentient homing bombs, skeletal army totems, or dozens of other wild options.
It’s Dangerous to Go Alone: Grab a friend and play through the entirety of UnderMine 2 with two-player local co-op. Discover character and item synergies that only exist when playing with a partner, or have someone to hold you if things get overwhelming.
Full Mod and Workshop Support: Easily create new items, characters, encounters, quests, and more with paintable tilesets, a visual scripting editor, and other included development tools. You can also easily download other players’ creations through Steam Workshop.
