The Crust the Crust Game Helium-3 — Wiki & Guide
the Crust Game Helium-3 explained: Helium-3 harvesting, outposts and fusion power. Facts sourced from official pages, wiki and community discussions.
Helium-3 is The Crust's late-game prize resource: you can't mine it at your main base — you claim distant territories, build outposts, and run helium harvesters there, then truck the gas home to feed energy cells and the massive fusion generator. The key numbers, documented from a creator's first outpost run:
| Helium-3 fact | Value |
|---|---|
| Deposit size example | ~8,278 helium per site |
| Extraction pace | 12 weeks per extraction cycle |
| Harvester upgrade | +20% extraction speed |
| Outpost power (RTG) | 30 energy |
| Fusion generator output | 1,000 energy ("like 50 RTGs") |
| Storage | 1,024 units per box |
| Territory requirement | ≥3 probes to mark; monthly rent (−25% with research) |
| First haul recorded | 12 units |
Why you want Helium-3
The endgame power chain: helium-3 feeds energy cells, and energy cells power the fusion generator — "very, very pricey, but it does make 1,000 energy," which one streamer computed as "like 50 RTGs." The resource also sits in the wiki's mining table alongside regolith and water ice as one of the Moon's native materials. If your run is economy-first, helium-3 territory is also simply valuable land: the in-game guidance quoted during outpost setup says "if the outpost is built in the right place, the profit from helium-3 extraction will justify the cost."
How to get it: the outpost loop
- Research the probe line. Territory probes and resource probes arrive late in the tree; drone manufacturing itself is a "heck of a lot" of blue and orange science.
- Mark a territory. On the orbital level, open probe management and mark an area with your territory probes — at least three probes must bracket the zone. Marked zones get terrain-scanned, then unlock outpost construction. Two catches: there's a distance limit from your base (the streamer spent minutes discovering "all the nice spots are too far away"), and territories cost monthly rent ("renting new territories requires regular financial investment") — with a research that cuts rent 25%.
- Build the outpost. Send a cargo truck with modules; construction slots expand via the Outpost Structures research. Power it with the outpost RTG (30 power).
- Build the Helium Harvester. The harvester (with a +20% extraction speed upgrade) taps the local deposit — one site in the run showed ~8,278 helium available at a 12-week extraction pace. The Outpost Transport Node research lets one hub service multiple harvesters.
- Truck it home. Set a truck route from outpost to base; helium-3 stores in regular boxes (1,024 per box) via Helium Storage near the elevator. The first real haul in the run: 12 units — "it's slow, but we can do upgrades."
Community context
- Helium-3 searches are common enough that "the crust game helium 3" is one of the game's recognized search terms, and the New Horizons update era (which introduced outposts) produced dedicated harvesting series — e.g. "LET'S GATHER THAT HELIUM-3 NOW!" (episode 42 of a New Horizon playthrough) and Surtr Plays' "First Look At New Outposts And Helium."
- The outpost system extends beyond helium: the same territory mechanics support titanium and silicon outposts, regular refineries, and storage — "a chance to move part of the industry beyond the base," as the in-game tip puts it.
- Early outpost lessons from the run: don't double up trucks on one route (they queue at the base gate), and bring your own power math — the RTG's 30 power vs. its cost matters when every module also draws.
Quick answers
- Where is helium-3? In territories away from your base — found via resource probes, claimed with territory probes, harvested at outposts.
- How do I increase helium-3 production? Harvester speed upgrades (+20%), the transport node for multiple harvesters, and better truck logistics between outpost and base.
- What is helium-3 used for? Energy cells, which power the fusion generator — the largest single power source documented in the community materials (1,000 energy).
