Solo Lost Sector Mastery

Overview

Solo Lost Sector Mastery is an Europa World, Exploration triumph. Complete any Europa Lost Sector on Master difficulty alone.

How to complete

Choose Perdition, Bunker E15, or Concealed Void when its higher-difficulty version is available, and launch Master with no teammates. Prepare the sector's Champion counters and move through its rooms from safe cover.

Defeat the final boss and open the reward chest, staying solo throughout the run. Only one qualifying Europa sector is required; completing all three is unnecessary. A Master clear on another destination does not replace the Europa condition. This record does not require flawless completion.
