Dome Keeper: Infiltrator Miner Prestige Strategy

To maximize your score with the Infiltrator in Dome Keeper's Miner Prestige mode, keep your dome defenses minimal, reach Drill Tier 2 before hitting hard rock strata, use teleportation beacons to eliminate ore transit time, and redirect all surplus iron and water into the prestige multiplier once basic survival is stabilized.

Early Excavation and Upgrade Priorities

Your opening five cycles dictate whether your multiplier scales ahead of escalating alien waves. Avoid spending early iron on defensive enhancements; every early mineral must go toward movement and mining efficiency.

• Cycles 1–2: Dig directly beneath the dome stem to establish a central vertical shaft. Branch horizontally by two blocks whenever you expose raw iron veins. Pool your initial minerals to buy Drill Tier 1 immediately.
• Cycles 3–4: Expand horizontal sweeps across the soft dirt layer. Haul back enough iron to unlock your first movement speed upgrade so you can gather loose ore faster.
• Cycle 5 onward: Stop digging into multi-hit rock strata until you purchase Drill Tier 2. Striking dense stone without adequate drilling power wastes mining hits and cuts into combat preparation time.

Beacon Placement and Hauling Optimization

The Infiltrator relies on teleportation beacons to eliminate hauling delays across deep caverns. Poor beacon anchoring forces long transit walks, while proper placement allows you to mine until the last possible second.

1. Anchor the main return beacon: Place your primary beacon at the junction where the central vertical shaft meets your deepest horizontal branches.
2. Stage mined ore: Past the map's halfway depth, stop dragging minerals manually back to the dome cellar. Pile iron, water, and cobalt directly on the beacon pad.
3. Trigger batch returns: Once an entire vein is staged, activate your teleportation mechanic to jump yourself and the resources to the base right as the wave proximity alarm triggers.
4. Bypass bedrock barriers: If you hit impenetrable bedrock, place a marker and tunnel laterally rather than burning stamina and time trying to force a straight vertical descent.

Defensive Thresholds and Combat Priorities

Miner Prestige requires lean dome management. Over-investing in base integrity drains the resources needed for your score multiplier.

For dome loadouts, the Laser Dome provides precision targeting against flyers, while the Sword Dome cuts through dense melee groups with minimal early tech investment. Avoid purchasing raw hull health upgrades early; save cobalt for emergency structural repairs. Rely on basic shield installations or overcharge mechanics to absorb initial projectile volleys while you dispatch ground targets.

During alien waves, eliminate targets in this sequence:

1. Ranged Bombardiers: Target backline projectile spitters first to keep continuous chip damage from breaking your shield.
2. Heavy Bruisers: Use the Infiltrator's tactical tools to stagger or kite slow melee attackers before they impact the dome glass.
3. Swarm Flyers: Clear fast flying units with wide weapon sweeps or defensive pulse activations before perimeter health degrades.

If a wave breaches your shield, use a single cobalt for repairs only when dome integrity drops below safe operational limits. Never spend cobalt on cosmetic top-offs.

Timing Multipliers and the Final Cash-Out

The turning point of a Miner Prestige run occurs when you stop upgrading your keeper and shift all incoming resources into the prestige console. Converting too early leaves your base vulnerable to armored waves, while converting too late caps your maximum score.

Begin converting resources once you meet three criteria:

• Drill Tier 2 unlocked
• Carry Capacity 2 unlocked
• A primary weapon upgrade tier active that reliably defeats standard armored aliens

Convert minerals in calibrated batches. Water yields substantial multiplier growth, so store water caches until they can be deposited alongside large iron loads.

When alien wave scaling finally outpaces your lean dome defenses, begin the cash-out phase. Drop all remaining underground minerals into the converter, defend the dome through the active wave, and end the run with your multiplier fully converted.
