Special Operations

Special Operations are limited time challenges where players can earn unique Boss items through battle and even a new hero by completing specified objectives. Once the time for the mission has expired, the hero is put back in the vault. Special Operations can be accessed from the Flight Deck or the Mission screen.

While normal Missions require 10 energy to access battles, Spec Ops also require Unstable Iso-8 to do the events. It costs Unstable Iso-8 for battles and for Deploy missions. It can be obtained through Gifts from friends, dropped in battles or deploys, or purchased from the  store. However, once the mission is expired that flavor of Unstable Iso-8 goes away with it.
