About this game

Building on the best aspects of UnderMine, an acclaimed action-adventure roguelike, UnderMine 2 takes place immediately after the events of the original game, but can be played as a completely stand-alone experience.

Hundreds of new and classic items return and present a nearly infinite set of build possibilities. Charm enemies and use their abilities to your advantage. Cycle your potions endlessly and push your stats over the limit. Or grab a Fuel Injector and meme your way to victory by nuking a boss with a bomb that is far too large.

Camilla, demoted to Third Disciplinarian by King Faraam, struggles to bring the Goldmine back into operational form. Aid her, rescue helpful characters from the depths of the Undermine, and uncover what King Faraam is really up to. (Eventually, we are still in Early Access, after all.)

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.

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.

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.

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.

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.
