2★ Isogen Extraction is a Territory research that raises your base mining rate for 2★ Raw Isogen, from 10% at level 1 to 150% at level 12. It unlocks at R&D Department 30, the natural next step after 1★ Isogen Extraction as you push into higher Territory Capture zones.
What 2★ Isogen Extraction does
2★ Raw Isogen is the mid tier of the isogen family, mined in higher Territory Capture zones and refined into the Iso-Emulsion that pays for the deeper Territory research levels. This project multiplies your base 2★ Raw Isogen mining rate, which matters more each season as the tree’s later projects lean on mid-tier emulsion.

Unlock requirements
Level 1 needs R&D Department 30 plus Thorough Scanning 1 and Cargo Security 1. The rest of the ladder is in the table above.
Cost and research time
Per-level costs are in the table above. Maxing all 12 levels totals about 1.6M 1★ Iso-emulsion, 1.1B Dilithium. The base research time adds up to roughly 14.6 yr on paper; research speed bonuses cut real timers to a small fraction of that, so use it to compare levels, not to plan your calendar.
Is 2★ Isogen Extraction worth it?
Yes, as soon as your alliance holds zones with 2★ isogen nodes. Rate research on the resource you actually mine beats almost anything else in the tree for steady value. Combine it with Iso-Emulsion Wirkungsgrad so the refined side stretches too, and see the Territory Research guide for the whole branch.
