Seattle Day 3: The Flooded City and Infiltration

A boat trip through the flooded streets with six stops, then the way into the aquarium.

Two chapters. The Flooded City is a boat trip: the waterway runs past a fixed string of stops, and every one of them holds something for the checklist (six artifacts, two cards, a journal entry, two workbenches and a safe in all). Step off the boat at each stop before you drive on. Infiltration is short, with one journal entry.

Artifact: Sniper's NoteCollectible
Location
Seattle Day 3 · The Flooded City – Drive on toward the gunfire, where WLF and Seraphites are fighting, and before you join in steer hard left to the monorail train hanging off its track. Leave the boat at its end and walk up through the cars to a rope beside a locked door. Toss the rope up through the gap in the roof so it falls past the doorway on your right, climb to the roof and drop into the locked car, where the note lies on a red seat by a body. If no climb prompt appears, rappel out of that open doorway, swing to the frame under the locked car and climb in through its open door.
Requires
Summary

Boat stops: hotel, monorail, breweryQuest step
Location
Seattle Day 3 · The Flooded City – From the monorail car, which gives you a good spot to pick off some of the fighters below, head for Kingsgate Brewing Co., the building they are fighting over just past the broken train bridge. Clear it: most of the enemies hold the upper floors, so Trap Mines on the stairs and Molotovs work well.

About this guide

Three runs of the story, plus No Return alongside any of them. Run 1, on any difficulty below Grounded, takes every collectible, safe, manual, weapon and workbench; before the last chapter of that run, make a manual save to keep for cleanup. Run 2 is New Game+ on Very Light with Permadeath set to Per Chapter: it finishes the upgrades, which one run doesn't give enough Supplements and Parts for. Run 3 is Chronological mode on Grounded. After the credits, Chapter Select replays a chapter, with limits: the chapter list follows your latest autosave, so replaying an early chapter hides the later ones until you reload the cleanup save, and Supplements and Parts taken on a replay don't count toward the upgrades.
