Learn about non-combat ships like Constructors and Trade Ships, and industry research for resource extraction in Sins of a Solar Empire II.

Walkthrough
  1. 1
    Understand the roles of non-combat ships: Constructor Frigates (Assembly Drones for Advent, Junra Fabricators for Vasari) build structures near your planets. Trade Ships generate income by moving between trade ports. Refinery Ships extract and transport crystal and metal resources.

  2. Investigate the Industry research group to improve resource harvesting and planet colonization.
  • 2
    Research Deep Core Metal Mining (requires 1 Civics Lab) to increase metal extraction by 7% per level (2 levels available). Level 1 costs 400 Credits, 25 Crystals. Level 2 costs 500 Credits, 50 Crystals.
  • 3
    Research Rapid Hydrometallurgy (requires 2 Civics Labs, 2 Levels in Deep Core Metal Mining) to further increase metal extraction by 7% per level (2 levels available). Level 1 costs 600 Credits, 50 Metal, 100 Crystals. Level 2 costs 700 Credits, 75 Metal, 125 Crystals.
  • 4
    Research Nuclear Smelting (requires 4 Civics Labs, 2 Levels in Rapid Hydrometallurgy) for a final metal extraction increase of 7% per level (2 levels available). Level 1 costs 1000 Credits, 150 Metal, 250 Crystals. Level 2 costs 1100 Credits, 175 Metal, 275 Crystals.
  • 5
    Research Efficient Crystal Sorting (requires 2 Civics Labs) to increase crystal extraction by 7% per level (2 levels available). Level 1 costs 600 Credits, 50 Metal, 100 Crystals. Level 2 costs 700 Credits, 75 Metal, 125 Crystals.
  • 6
    Research Automated Mining Rigs (requires 3 Civics Labs, 2 Levels in Efficient Crystal Sorting) to further increase crystal extraction by 7% per level (2 levels available). Level 1 costs 800 Credits, 100 Metal, 175 Crystals. Level 2 costs 900 Credits, 125 Metal, 200 Crystals.
  • 7
    Research Shockwave Pulverization (requires 5 Civics Labs, 2 Levels in Automated Mining Rigs) for a final crystal extraction increase of 7% per level (2 levels available). Level 1 costs 1200 Credits, 200 Metal, 325 Crystals. Level 2 costs 1300 Credits, 225 Metal, 350 Crystals.
  • 8
    Research Orbital Commerce (requires 2 Civics Labs) to unlock Trade Ports, enabling trade ships to generate more credits. Costs 600 Credits, 50 Metal, 100 Crystals.
  • 9
    Research Orbital Refinement (requires 4 Civics Labs) to improve crystal extraction.
    • Tips
    • Protect your Constructor Frigates to ensure your planets develop properly.
    • Protect your Trade Ships to maintain a steady flow of income.
    • Ensure Refinery Ships have a clear path to and from your extractors to keep resources flowing.
    • Prioritize Efficient Crystal Sorting research early on, as crystals are vital for most actions.
    • Upgrades to resource extraction are key and should be acquired as soon as affordable.
