Unstable Isotope-8

Unstable Isotope-8 (Unstable Iso-8 or U Iso-8) are used specifically in Special Operations in addition to the normal requirements to initiate each battle or deploy. They are also used for researching various items that are only available from unlocking the Blueprints from completing Spec Op Tasks. Only Special Operations 1 required 5 Unstable Isotope-8 per battle or deploy and had no research. From Special Operations 2 forward, each deploy, incursions and normal battle requires 10 Unstable Iso-8 and each boss battle - Mini, Regular, Epic, and Group Boss - requires 20 UISO to initiate.

UISO are consumed on research. Spec Ops 2 to 16, Blueprints specific to each Special Operation usually requires 80, 100, and 120 Unstable Iso-8 for the research. Spec Ops 17 to 33 requires 40 and 60 Unstable Iso-8.

Starting UISO may vary from Spec Ops. On Spec Ops 1, started at between 65 and 500 UISO to players. From Spec Ops 2 to 33 and 35 (except Spec Ops 3), started with 440 UISO. Spec Ops 3 started at 550 U Iso-8. Spec Ops 34 and 36 started at 600 UISO.

Unstable Isotope-8 that obtained before Special Operations is unlocked may not be updated visually until refreshed.
