Surviving the Aftermath

To use the Overtime ability on a building, you need to first reach the point in a game with the DLC active that Moon Rock begins to land in your colony. Then you'll need to build a Moon Rock Scavenger building and move the work area to any location the rocks land to gather Lunar Dust.

Once you begin collecting it, you will see the Overtime icon when you highlight a production building. It costs 10 pieces of Lunar Dust every time you use the ability so it will take a bit of time to reach 100 uses. Larger rocks with more dust do seem to fall more often the longer your colony survives. Avoid crafting Antistress meds as it uses these as an ingredient.
