Confirm quest completion
The QUEST COMPLETED: RECURSIONS AND ITERATIONS banner appears; the map and inventory show the completed objectives and updated key items.
Find the equipment camp and follow the beacon
The first terrace holds the researchers’ equipment, tents and crates, but the team has moved on. Beyond The Spire, the route through Hallway Trail leads to researchers lying dead in an office. The dead researchers wear white hazmat suits, while Keep Searching for the Team keeps the investigation moving.
Follow the changing camp and collect Grist’s device
The return to the office changes what Dylan sees: researchers work at their consoles, then become corpses again. One member is still missing. Dr. Grist explains that time is being patterned here, leaving multiple versions of both the camp and its occupants.
Grist has experienced months below the Sinkhole. That relative time could mean months of additional research. Find a method for sending back the team’s data across every iteration and timeline. Grist’s device gives Dylan a way to track the fluctuations; its yellow circle marks the search area on the Underpass map.
When Track the Time Fluctuations returns, reopen the Underpass map: its yellow quest circle moves as the investigation shifts between research sites.
Reach Ayad and restore power to the terminal
Ayad’s missing charges have left the research terminal without power. The team laid yellow tape to keep from getting lost, and the connected yellow lines lead between the supplies. The map also marks the research sites and the power-restoration radius.
Unit 1 begins with two battery units and one charge present. Follow the yellow tape, strike the power switches and terminals along the route, then interact with the final power unit. Return to Ayad at the console after restoring power. Back at his console, the timeline shifts again: Ayad falls dead, a duplicate speaks, and Dylan learns that the attempted transmission failed.
Find Grist at the cliff edge
The researchers by the whiteboard place Grist near the edge of camp. On the balcony, she says she has spent a year researching. Dylan counters that people on the surface survive in at least some timelines and that another version of Grist sent him to find her. She agrees to keep working so another timeline can benefit from what she learns.
Retrieve Grist’s log and defend the Transmission Tower
The next changed campsite contains bodies, scattered documents and the audio collectible Grist Research Log #3. From there, the tower’s beacon leads across the gap to its rocky peak, where red enemies attack from the ground and air.
Investigate Dylan’s voice and cross with Grist
Pope’s initial analysis covers decades of research across multiple timelines, yet finds nothing that can stop the patterning. She calls the mission unsuccessful at this stage. Dylan then hears his own voice despite not speaking, drawing him toward the Cable Car station.
Inside the car, Grist needs to reach a spot directly beneath the Oldest House and asks Dylan to protect her while she places the relays. The car carries them across the chasm, but Grist disappears before it reaches the far landing.
Follow the relays and recover the final probe
Farther down, the pipes run through orange sludge and green-lit stalagmites. The message asks a surviving version of its speaker to cross the chasm and says another version must finish the job; beyond it lie another Dylan encased in blue crystal and the collectible I Don’t Mind Dying.
Grist lies in the red-lit cavern beside a dropped probe. The quest shifts to Place the Final Probe Relay, and the Underpass map marks its destination.
Carry the probe to the tree and complete the quest
Carry the probe along the massive pipes, following the orange pipeline across the abyss. Take it through the bending pipe tunnel into the vast underground cavern beneath the Oldest House. Your destination is the green tree growing alone on a mound at the cavern’s center.
Place the relay to start the montage. You regain control beside the sapling, with the deployed relay next to it, and Pope comes over the radio. She discusses the incoming data.
The banner confirms “QUEST COMPLETED: RECURSIONS AND ITERATIONS”, awarding you +1 Living Shard and the Prime Candidate Restraint Suit. Your key items change too: Grist’s Tracking Device is removed when you finish the quest. The objectives are complete, and Dylan turns to his meeting with Zoe.
