Dome Keeper Mobile: How to Balance Mining and Wave Defense

To survive the run loop in Dome Keeper Mobile, prioritize your first upgrades on drill impact and keeper speed, mine in horizontal corridors spaced two blocks apart, and start your surface ascent well before the wave timer expires. Arriving late forces your dome to take unassisted damage, wasting mineral stockpiles on repairs instead of critical upgrades.

Managing the Wave Clock and Resource Hauling

Every round gives you a brief interval between monster attacks to dig into the subterranean map. Because carrying materials adds drag and slows your upward flight, your return trip always takes longer than descending.

Follow these rules to avoid getting caught underground:

Factor in cargo weight: Carrying multiple mineral orbs substantially lowers your vertical thrust. If the incoming attack alert sounds while you are deep underground, drop excess minerals at shaft junctions and ascend light.
Stage resources at the main shaft: Pile excavated ore at the base of your central vertical corridor. This lets you mine continuously during calm periods and grab only what you can safely carry right before an attack.
Protect base integrity: Your dome does not passively regenerate health. Every hit sustained consumes repair materials that would otherwise fund offensive weapons or deeper mining equipment.
Haul relics independently: Bulky subterranean relics cannot be converted instantly on-site. Dedicate a specific trip to haul each relic directly into the dome cradle.

Mining Efficiency and Tunnel Layout

Deeper underground layers feature harder rock strata that require more drill hits to break. Aimless excavation wastes valuable time and stamina between waves.

To maximize your yield:

Dig a straight vertical drop down the center to serve as your primary travel lane.
Branch out into horizontal search corridors spaced two blocks apart. Because minerals occupy multiple blocks, this grid pattern reveals adjacent resource veins without forcing you to dig out every intermediate wall.
Open hidden caves as soon as you detect them to secure secondary gadgets, which provide automated utility and scanning functions to speed up later dives.

Upgrade Priority: Mining vs. Combat

Investing excavated minerals requires balancing your excavation speed against the rising strength of each alien wave.

Phase	Upgrade Priority	Tactical Value	Trade-Off
Early Game	Drill Strength & Movement Speed	Rapid block clearing and faster resource delivery	Keeps the dome hull fragile and reliant on accurate shooting
Mid Game	Weapon Damage & Rotation Speed	Clears split air and ground waves before they impact	Diverts materials away from deep-strata drill tools
Late Game	Dome Shielding & Hull Repairs	Absorbs burst hits from heavy ground and aerial swarms	Consumes ore reserves that could fund secondary tech

Begin each run by upgrading your base drill tier and jetpack speed. Once you can clear basic rock in one or two hits, shift resources into dome weapon power and tracking speed so you can destroy incoming monsters before they reach the glass.

Target Prioritization During Alien Waves

When manning the dome controls, alien waves split into distinct categories that require rapid target assessment:

Aerial Monsters: Fast flyers approach from high angles and fire ranged projectiles. Target aerial units first, as their mobility allows them to chip away at your dome while you track ground targets.
Ground Monsters: Heavy melee units walk directly to the dome base to deliver high-damage impacts. Once aerial threats are cleared, sweep weapon fire downward to eliminate clustered ground siege units before they begin striking the perimeter.

Setup Selection

Before starting an expedition, tailor your loadout around your intended strategy:

Keepers and Domes: Dome Keeper features two keeper types and four dome designs, each shifting your mobility baseline and defensive profile.
Primary Gadgets: Choose one of four primary gadgets to dictate your logistics. Transport gadgets that automate resource hauling let you stay deep in the mines longer, freeing you to focus resource spending entirely on drill upgrades and manual turret defense.
