Upgrade Chain (4 tiers)

|---|---|---|---|---|---|---|---|
| L1 | Atmospheric Recycler | 600,000 | 150 | 40 | — | — | 2 |
| L2 | Climate Control Array | 1,300,000 | 225 | 60 | — | — | 2 |

| L4 | Full Habitat Dome | 10,500,000 | 375 | 100 | — | — | 2 |
Each tier is built by upgrading the one below it. Cost, build time and power draw climb with the tier; the recipe it runs stays the same.
