Quest overview

  • Quest giver: Shani (unlocks after "Paving the Way").
  • Objectives: Decrypt at Fuel Control -> Decrypt at Arrival Building top floor (same raid).
  • Rewards: Defibrillator x3, Trailblazer Grenade x3.
  • Failure condition: Death before both decrypts = restart the quest.

Step 1: Fuel Control Building (Northeast)

Enter the Fuel Control Building near Rocket Assembly. It's dark - use a flashlight. In the server room, the distinct blue Magnetic Decryptor sits on the southeast wall. Interact to start decryption; it will fail and point you to the next location.

Step 2: Arrival Building top floor (Northwest)

Cross to the Arrival Building on the northwest side. Go straight upstairs to the top floor. In the central corridor, find the long rows of old computer banks; one is the second Magnetic Decryptor. Interact to complete the quest objectives.
