UnderDeep

Dig deeper, grow stronger, and transform every swing of your pickaxe into a thriving automated mining operation.
Choose your path through the earth one block at a time. Break tougher materials, uncover valuable rewards, collect gold and experience, and develop your miner with permanent upgrades and character abilities.
Explore an ever-deepening mine filled with distinct biomes, special blocks, valuable deposits, and treasure chests. Every descent brings greater challenges—and greater rewards.
BUILD YOUR MINER
Spend your gold on a branching tree of permanent upgrades. Increase your mining power, improve your rewards, strengthen automatic excavation, and uncover new ways to progress.
MASTER NEW ABILITIES
Earn ability points as you level up, develop different skill paths, and equip active and passive abilities that change how you approach the mine.
CHOOSE YOUR PATH
Every block matters. Carve your own route through the grid, pursue valuable deposits, and return to previously excavated areas whenever you want to review your journey.
KEEP DIGGING WHILE YOU DO OTHER THINGS
Let automatic excavation continue your progress while the game sits in a compact window beside your other applications. Offline progress also helps your mining operation move forward between sessions.
