Innovative Strategies for Lunar Expansion in THE MOON BOY

The Gate Chain Is the Game

Moon Base has seven buildings, and most of them are locked behind another building's level. You can't just save up and buy whatever looks shiny. The unlock chain looks like this:

• Solar Array and Reactor Core are open from the start.
• Regolith Extractor needs Reactor Core level 3.
• Ice Harvester needs Solar Array level 5.
• Hydroponics Bay needs Ice Harvester level 8.
• Orbital Relay needs Reactor Core level 15.
• Quantum Extractor needs Orbital Relay level 10 — and it costs TMBX, not Moon Dust.

Every expansion decision comes back to this chain. If you want the big producers later, you have to feed the gatekeepers now.

Reactor Core First. Not Close — First.

Every building produces Moon Dust per hour. The Reactor Core is the only one that does two things at once: +2 MD/h per level and +3 to your energy ceiling per level. More energy means more taps per session, more taps means more score and more instant Moon Dust. It also happens to be the thing you're physically tapping — level it up and the reactor itself changes look across four tiers.

And it gates twice. Level 3 opens the Regolith Extractor (a solid +20 MD/h per level for a 500 MD entry price). Level 15 opens the Orbital Relay, which is where the serious +300 MD/h per level numbers start. No other building pulls that much weight.

The trade-off: Reactor Core's cost curve is steep early — ×1.6 per level up to level 10, easing to ×1.35 from 11 to 25. It hurts, but you're buying energy capacity and two unlocks with the same Moon Dust. Pay it.

The Solar Array Line

Solar Array is your cheap workhorse — 50 MD to start, +5 MD/h per level. Nobody expands a base on Solar Arrays alone, but level 5 unlocks the Ice Harvester (+50 MD/h per level), and Ice Harvester level 8 unlocks the Hydroponics Bay (+120 MD/h per level). That's the whole left side of your economy, and it starts with a 50 MD building.

Get Solar Array to 5 early. It's cheap, and the Ice Harvester waiting behind it out-produces it ten to one.

The Long Climb: Orbital Relay and the Quantum Extractor

The Orbital Relay costs 30,000 MD to start and scales at ×1.6 per level. It's expensive because it's worth it — +300 MD/h per level — and because it guards the endgame: get it to level 10 and the Quantum Extractor unlocks.

The Quantum Extractor is different from everything else. It's priced in TMBX (10 TMBX at level 1, ×1.25 per level, max level 10), and buying a level triggers a real on-ledger TMBX payment — actual tokens leaving your wallet, not a Moon Dust deduction. In exchange: +1,500 MD/h per level. It's genuinely late-game, and it's the one place your on-chain holdings and your in-game economy meet head-on.

Don't Sleep Past the Cap

One more thing that shapes expansion: your buildings keep producing while you're offline, but only for 8 hours. After that, production sits capped until you come back and collect. The bigger your MD/h, the more an overnight-and-a-workday absence costs you. Expansion isn't just about buying buildings — it's about actually banking what they make.

The Short Version

Reactor Core to 3, Solar Array to 5, then let the Regolith Extractor and Ice Harvester carry your income. Push Reactor Core toward 15 for the Orbital Relay, grind the Relay to 10, and start weighing whether the Quantum Extractor is worth real TMBX to you. That's the whole map. Everything else is discipline.
