    Continue northwest and scan a locked door. Head west to a circular chamber with three sets of Holo Locks.

    Use the hallway where you found the Power Cell as a bottleneck. Place traps like Blast Tripwires on or near stairs.
  24. 24
    Pick off enemies from the hallway using a Sharpshot Bow.
Tips
  • Use stealth to eliminate the Corrupted Watcher initially.
  • The elite Cultist is a tougher target; a Sharpshot Bow with Triple Shot is effective.
  • The hallway near the Power Cell location serves as a good defensive position against the Cultists and machines in the next chamber.
  • Traps, especially Blast Tripwires, can be very effective in the chamber with numerous enemies.
  • Experience Points
  • Loot from defeated enemies and chests
  • Power Cell (4/5 collected)
  • Various Datapoints (Audio and Text)
