Central Station

Central Station, or Deepsea Central Station as it is commonly referred to as, is the primary hub of the Deepsea Metro and starting point of the Octo Expansion.

Gameplay
After completing the tutorial Abandoned Station, Agent 8 and Cap'n Cuttlefish find themselves at the Central Station. No weapons are allowed in the area. On an initial playthrough, the only things of note in this station is the actual metro train, which can be boarded in order to access any other station, and the Telephone, who will act the primary catalyst of the Octo Expansion, granting Agent 8 a CQ Card and a CQ-80 device before giving them their objective. After completing any of the thang stages, Agent 8 will return to the Central Station with the thang. After collecting all four thangs, interacting with the Telephone will trigger the escape sequence of stages.

Postgame
After completing the Octo Expansion, Agent 8 can return to Central Station and go to the remains of the blender in order to replay the final act of the game or to watch the credits, which are known as "Remember the fight" and "Remember the light" respectively.

Additionally, after completing the Octo Expansion, a vending machine starts functioning which accepts either CQ Points or mem medals. The vending machine randomly gives out items, including food and drink tickets, Cash, and ability chunks in varying quantities. When exchanging mem medals, it may also reward more CQ Points.

Secret Boss: Inner Agent 3
Upon completing all the Test Chambers and collecting all the mem cakes, Agent 8's final memory is unlocked. Locker number eight on the station's platform opens and interacting with it triggers a battle with their "Inner Agent 3". This acts as a secret boss in the Octo Expansion. Beating this boss rewards players with the gear piece.

Trivia

 * In a screenshot released shortly after the announcement of the Octo Expansion, this station was shown on the Deepsea Metro map. At that time, the translation was not yet finalized, and the station's subtitle was "Promised land here we come!"
