Museum research and Urbex key: the Gridfall quest order

The Urbex key belongs to Beneath the Surface, after The Case of the Missing Curator and Field Notes and Loose Bolts. Meeting Atlas underground early is not the same as finishing those prerequisites.

Find the curator

Finish Keeping the Lights On, then repair Mita’s workstation and report to her. At the Museum, ask the Attendant, Archivist, Conservator, Historian and Tourist about Atlas. Return the news to Mita, then search for Atlas in the Underground.

The five interviews are individual objectives. Finding Atlas without completing the preceding conversations can leave a different stage active in the quest log.

Complete two Museum bundles

Field Notes and Loose Bolts requires two Museum research bundles. Complete the hand-ins and report to Atlas. Merely finding the station or collecting artifacts does not complete a donation objective.

Research rewards can also unlock station upgrades and recipes. Those rewards are distinct from the quest’s check for two completed bundles. The Refining Station guide explains why its level 3 unlock needs a full research page rather than only two arbitrary bundles.

Obtain and use the key

Beneath the Surface then directs you to ask Mita for an Urbex key, repair 3 underground pillars and meet her at the workshop. Follow the active objective instead of assuming that every blocked underground route opens when you first reach Gridfall.

Players have reported genuinely broken quest states, but a missing key alone does not establish that bug. A November discussion also describes a stalled route resolved by finishing the research hand-ins. Compare your active stage with this order before repeating the same conversation. The Gridfall repairs guide covers the preceding gate.
