Detailed walkthrough for Harold Halibut, covering Chapter 1.4 (The Sample), Chapter 1.5 (Through the Shaft), and Chapter 1.6 (The Encounter), including tasks, notes, and trophies.

This guide covers Chapters 1.4, 1.5, and 1.6 of Harold Halibut, focusing on tasks, note entries, and trophy progression, particularly related to Professor Mareaux's lab and the surrounding areas.

Chapter 1.4 - The Sample

After waking up, head to the lab to speak with Professor Mareaux for your main tasks. Before starting, visit the Agora Arcades and enter Gertrude's Bier Zone to listen to Alon and Zim's conversation for the Busybody Trophy.

  • Note Entries: Cyrus Plan (Talk to Cyrus), Stranger Danger (Talk to Liis), Countdown (Complete Rock Delivery).

Main Tasks:

  1. Rock Delivery: Go to Brigitte in the Energy District. A minigame involves stopping a conveyer belt on red rocks, followed by crushing and spraying samples three times.
  2. Filter Station Cleanup: Return to Filtration Pump 014F and unclog the filter indicated by an orange-glowing symbol.
  3. The Sample is Ready: Crucially, go directly to Brigitte to pick up the sample to unlock the Neo-Luddite Trophy/Achievement. Then, in the lab, use the lever to pull down the sample shelf, place the sample in the microscopic machine, and trigger a cutscene with Professor Mareaux.
  4. Meet Felix at the Agora Arcades: After the cutscene, check your PDA for a message from Felix. Travel to the Agora Arcades via the Tube System to meet him.

After meeting Felix, follow him through the ventilation system of All Water. You will part ways with him after the second ventilation shaft.

  • Note Entries: The Scout & Agent Harold (automatic), Tea with Mareaux (automatic).

Main Tasks:
