Tips
  • Failure to complete calls can result in City HP loss, potentially leading to an achievement loss.
  • Hacking sequences are timed and require careful navigation and strategy.
  • Dialogue choices can impact relationships with characters like Blazer.
  • Pay attention to hero stat requirements and exclusive skills for optimal assignments.
  • Use special items and healing heroes when injuries are high.
  • Completing the Red Ring weakening objective is crucial for ending the shift and potentially unlocking future options.
Saving the city may allow an ex-team member to rejoin later. Losing the battle removes this option. The shift ends when the Red Ring HP bar reaches 0.
