Shackleton Base: Below. Within. Above.

Place the Fracture on the main board: a red one on an edge between sectors where you have a structure, a yellow one in a sector where you have a structure, or a blue one over a Corporation token next to a sector where you have a structure. Then take the matching bonus shown for that Fracture type (p. 7).

Adjacent sectors do not earn Credits, and resources or Corporation tokens covered by a Fracture do not produce or activate until it is repaired. When exploiting a sector with a Fracture in or around it, use an astronaut whose type matches the Fracture, take the Fracture instead of activating that sector, flip it, and gain 2 Reputation (p. 7).

When you gain a Civilian, take the one with the lowest Reputation requirement you meet (0, 4, 8, or 12) and place it in an available space in your base. Sending one from your base to an available Crater spot costs 1 Reputation and lets you exploit one sector in that row; you cannot do this at 0 Reputation (p. 5).

You may move an astronaut from your base into the Hall immediately after placing it, but the Hall’s bonus is gained during the Income phase only if an astronaut is next to it. Halls and astronaut spaces are unlocked as your Drill marker advances (p. 7).

To overbuild one of your structures, spend Blueprints equal to the size of the new structure; you do not spend Titanium or Rare Earth. Overbuilding does not increase your presence in the sector: its size remains the size of the structure at the bottom (p. 9).
