A glowing seam beyond a wall of stone. A creature guarding the easier route. A buried machine that could open a permanent way through.
Deep Delve is a mining adventure about choosing what to uncover next, building a more capable rig and bringing your discoveries home.
FOLLOW THE LIGHT
Steer continuously through open tunnels and hold your direction to drill. Follow ore and crystal trails, choose between branching routes and inspect what lies beyond the next barrier. Tap-route controls are also available in Settings.
BUILD A RIG THAT CAN GO FURTHER
Bank your haul and invest in energy, hull and cargo upgrades. Earn new drill assemblies and useful equipment through exploration. Progression unlocks come from discoveries and restored machinery, so preparation and the route you choose both matter.
SHAPE YOUR WAY THROUGH
Recover or craft Bore Charges, Seam Lasers and Fire Blasts. Use grapples, crossings and restored machinery where the mine demands more than drilling. Open tunnels and completed connections stay part of your mine.
CHOOSE YOUR ENCOUNTERS
Creatures move and attack in real time. Avoid a patrol, dodge a charge or find an opening to counterattack. Uncover optional bosses and return for rematches, remaining seams and field projects. Menus pause the action.
BRING THE UNDERGROUND TO LIFE
Recover fossils and lost machinery, explore connected galleries and restore routes into deeper chambers. The authored campaign has an ending, with optional discoveries and unfinished projects to return to afterward.
PLAY AND SAVE LOCALLY
Core exploration works offline and needs no account. Progress saves on your device and does not sync between devices. Purchase restoration recovers supported ownership, not your local mine.
OPTIONAL PREPARATION
The core game is free to play. Optional purchases offer extra preparation. Automatic ad breaks are limited to eligible banked trips; products that remove them state their scope. At any depot, choose a supply and complete an optional rewarded video to receive one, subject to availability, recipe and carry limits. A shared cooldown follows each earned ad supply. This is separate from the banked-trip video bonus. Rewarded videos remain optional even with automatic ads removed. Core progression and tool recipes remain earnable through play. Online services require a connection.
Sound, reduced motion, effect density, larger text, steering preferences and assistive controls are available in Settings. Optional game usage reports start off and require a separate eligible Allow choice each session.
Drill a persistent mine, upgrade your rig and uncover what waits below.
