Milestone tier progression
HUB milestones unlock buildings, recipes, equipment, and other rewards. Tier 0 upgrades are sequential; completing Tier 0 opens Tiers 1 and 2, and Space Elevator phases unlock higher tiers.
How it works
Complete milestones at the HUB Terminal by supplying the specified resources. Parts submitted there cannot be recovered. At the start of a new session, Tier 0 is available unless onboarding is skipped; completing Tier 0 opens Tiers 1 and 2. Higher tiers become available through Space Elevator phases.
Read the supporting references
A source-bounded reference to named MAM research unlocks and HUB milestone rewards shown in the supplied evidence windows. It records stated effects, costs, and progression conditions where those details appear; unsupported details are omitted. Guidance explains the referenced mechanics; it is not a tested damage ranking. Check the stated edition and source version before applying a patch-specific detail.
