About
A dungeon adventure on your wrist.
Descend through 20 handcrafted levels of ancient cells, forgotten crypts, dangerous mines and haunted depths as you fight your way toward the heart of Underkeep.
Tap anywhere to move. Tap an enemy to strike with your sword. Simple controls make Underkeep easy to pick up, while new enemies, traps and puzzles make each descent more dangerous.
EXPLORE
Navigate twisting dungeon rooms, hunt for keys, open gates, discover hidden paths and find your way deeper underground.
FIGHT
Battle rats, slimes, skeletons, bats, spiders, ghosts, mages, armoured guards and more. Every enemy behaves differently, so watch their movements and choose when to strike.
SURVIVE
Dodge charging enemies, magical attacks, spikes and other dungeon hazards. Learn each enemy's weakness and make every sword strike count.
DESCEND
Journey through five distinct areas across 20 levels, culminating in a final confrontation with the Warden.
Designed specifically for Apple Watch with simple tap controls, short levels and no complicated menus.
Underkeep is completely free.
