Chapter 3 walkthrough
The rail-cavern panel needs four fuses. Follow the upper route for the office and shed key before returning to the tracks.
In this guide
Get the train controls working
Use the yellow goo to climb from the flooded opening. At the train control building, activate the exterior lever, then the red button inside. Collect the dynamite, blast the blocked metal door and start the generator beyond it. Return to the train controls after restoring that power.
Make a mental note of the console you must return to. A restored generator is a prerequisite; it does not mean the distant vehicle has already been operated.
Open the freight route
Keep momentum when jumping onto adhesive goo, then jump away toward the next support. The freight route requires its gate key, repaired fusebox and yellow generator before you operate the platform controls. Red buttons reposition suspended freight equipment.
Read a platform’s destination before committing to a jump. If a route looks impossible, first check whether you are looking at the platform’s starting position rather than its moved position.
Find the four rail-cavern fuses
Search these four stops around the central rail panel:
| Stop | Where to look |
|---|---|
| Generator workbench | Inspect the work surface by the generator. |
| Lower office | Use the low office with the broad window as your landmark. |
| Upper wooden office | Follow the elevated route before dropping back to the tracks. |
| Trackside shed | Get the Shed Key from the high cabinet near the Call It In stairs. |
Panel complete, then onward
With four green indicators, use the main console. The later Motherlode area has its own power interaction; treat it as a new local objective.
If the second Allo encounter refuses to acknowledge the four fuses, check your game update before assuming you missed another item. Steam patch 1.0.9 specifically addresses the four-fuse issue. See the relevant patch fixes.
