Discover the secrets of the UnderMine, one peasant at a time

Want to keep up with UnderMine news? Just add yourself to this mailing list and we'll get at you with the important stuff, like when we come out.




UnderMine is an action-adventure, roguelike with a few RPGish elements tossed in. Delve into the UnderMine as a lowly peasant seeking fortune and freedom. Each journey promises challenge, discovery, riches, and untimely death. That's okay though, because your belongings will be passed on to the next peasant, who will hopefully do a little better.

Action-Adventure. Rogue-like. RPG.

Blending combat and dungeon crawling from traditional roguelikes like “The Binding of Isaac,” with the progression of roguelites like “Rogue Legacy,” UnderMine delivers a fresh new entry to the genre. Mine gold on each run and increase the peasant’s power by finding powerful relics. Rescue NPCs and return them to the hub where they will open up shop and offer powerful upgrades for future runs. Delve deeper, exploring each new area, discover its many secrets and ultimately defeat its powerful boss.




  • Dungeon Crawling: Forge that perfect run where you find all the right items, all the right secrets, and get all the right rolls to become a peasant god of destruction.

  • Discovery and Exploration: Bomb walls, blow up rocks, light torches, and discover secret passages, hidden characters, loot, upgrades, and more.

  • Character Progression: The peasants keep dying, but your upgrades pass on. Unlock new abilities that will help in combat and open up new areas to explore.

  • Bosses That Don’t Mess Around: Challenge enormous bosses that take a combination of upgrades and skill to take down.


Thorium is Derek Johnson and Clint Tasker. Two guys brought together by their passion for games. We each left professional game development jobs to pursue indie game dev, hoping to create a game on the same level as the ones we grew up loving. UnderMine for us is an opportunity to show the world what we are all about as developers, and a way to communicate directly with our audience.






Hi! I’m Derek, a software engineer from Vancouver, BC. I used to work at Relic and now am the original founder of Thorium. I have a dog named Dillon, who is named after Carl Weathers' character from Predator and has been pushing too many pencils.





Hey! I’m Clint, a game designer from Seattle, WA. I met Derek at Relic and now am the co-founder of Thorium. I’ve worked in AAA console, PC, and mobile development. Now I’m an indie. One day I’ll show Hideo Kojima my Foxhound tattoo, but not in a weird or creepy way.
