Tubular!

Chapter 1.1 - An Ordinary Day: After a cutscene, you gain control of Harold in the All Water District Station. Interact with the boy near reception to leave. Follow Professor Mareaux to the Central Station via the All Water Tube System, then select the Lab District. This unlocks the 'Tubular!' trophy.

Chapter 1.2 - The Hang of It: After a cutscene with Professor Mareaux, follow her to the laboratory and receive tasks and the PDA.

Main Task [1] Clean the Filter Station: Navigate to the lowest section of the Lab District, find the Filtration Pump014F room, interact with the lever, and select the correct symbols (∝🗌 and 🌀?) to flush the pump.

Main Task [2] Feed the Fish: The fish feeder is out of food. Head to the Botanical Concepts 022F room (LVL 1, right from the T-section) to find Cyrus and get fish food. Return to the lab and use the feeder. (Author's Suggestion: Combine this with the filter station task before returning to the lab).

Main Task [3] Go to the Agora Arcades: Exit the lab and head to the Tube System. A cutscene will play, and you'll be given a new task.

Main Task [4] Watch the Announcement: From the Tube System exit, go to the Lounge room (right from the T-section). Meet Chris and watch the announcement. This unlocks the 'Chris in the Lounge' and 'Buoy Announcement' note entries.

Main Task [5] Time to Sleep: After the announcement, head back to the lab, go left from the fish feeder, down the stairs to your room, and interact with the bed.
