Where: the woods and Fairlight Outpost, the tunnels and subway under the city, the district around the Kalona Theatre, Monroe Library and Landa Memorial Hospital, a bridge convoy, the clock tower, and a fort.
To find: 36 collectibles, 38 Hard Cases and 3 secondary objectives. Last Foothold is the open chapter, with a map; two of its collectibles only appear inside its secondary objectives.
Watch for: the Corpser at the end of Enemy Lines, Rooftop Mayday, which only opens after a main-story fight, and the last Hard Case of the act, which gives no alert and does not glow.
1. Stranded
5 collectibles · 3 Hard Cases · no secondary objectives
Through the woods to Fairlight Outpost and its sub-station. Linear, with a Supply Cache by the large warehouse.
-
1
Woods and outpost
Work through the woods; after a rope descent the road forks by a mauled body, and the knife is a short way down the left branch while the objective is right. Cut through the locked gate, clear the Locust, then climb the shipping container over the fence into the outpost.
-
2
Restore the power
The objective sends you into the sub-station. Search outside it first: the map is between the generators on the right of the fence doorway, the target round the back on the left. The last Hard Case is just inside the door.

-
2
The dark tunnel and the crashed cars
To go on you climb over crashed subway cars. Before that, follow the tracks the other way, down the dark tunnel toward a red light, for the flashlight; Avila's tags are down a stairway on the left before the cars.
-
3
Boss: the Corpser
At the end of the chapter. Its leg slam sends a shockwave that knocks you down; hide behind the pillars. At first your guns do nothing: wait for it to scream, rear back and lunge, and stand behind a pillar so the lunge brings the pillar down on it. Repeat. After enough damage it runs and you follow it to a second arena, where guns hurt it too, but dropping pillars on it is still the main damage. Tickers and Juvies join in; kick Tickers away with B. Beating it unlocks Get Back You Eight-legged Freak.

7. Act 3 Completion
Cross-checked
Cross-checked on 5 October 2026 and re-checked on 6 October 2026 against the Act 3 guides of Game8, The Nerd Stash, TechWiser, Gamer Social Club and Gamers Beacon, the Act 3 Hard Case lists of IGN and Gamers Beacon, and Gamer Social Club's Corpser guide; all five guides agree on 36 collectibles and their chapters, and the route order, the Hard Cases and the secondary objectives follow Gamer Social Club, whose Hard Case count for every chapter Gamers Beacon matches, as do IGN for the first five chapters and Game8 for the first two. Where they differ: The Nerd Stash and TechWiser write Kevin Garbor and Game8 Kevin Gabor; Gamer Social Club gives Rooftop Mayday and its collectible the same directions as Lost in the Park, so only the unlock condition from The Nerd Stash and TechWiser is given; Gamer Social Club's twelfth Hard Case in Last Foothold repeats the eleventh's directions, and Gamers Beacon gives it no fixed place. Not from a playthrough: nobody here has played it, and what the sources do not describe is not on this page.
