WILL: Follow the Light: Chapter 3 & 4 Walkthrough – Lighthouse to Fog

For Chapters 3 and 4, the clean progression is this: finish the island and lighthouse logic in order, use 314 when the keypad blocks you, restore power through the fuel-barrel elevator setup, set the beacon and radio correctly, then solve the loading-yard crane puzzles so you can repair the lantern and cross the fog sea with minimal fuel waste. If you try to brute-force these chapters room by room, WILL: Follow the Light can feel much more obscure than it actually is.

This walkthrough focuses on the main progression path and the spots most likely to stall you: the lighthouse sequence, the crane-and-crates logistics puzzle, the lantern bench repair, and the fog navigation that follows. Optional cassette tapes fit naturally into this route, but the priority here is getting you unstuck without unnecessary backtracking.

Fast route through Chapters 3 and 4

• On the island, follow the lighthouse puzzle chain instead of searching every room at random.
• When you reach the code-gated step, enter 314.
• Use the barrel-and-elevator setup to restore generator power.
• After power is restored, complete the beacon setup and keep the radio frequency 120.5 in mind for navigation.
• In the loading area, push the first crate onto the chalk mark and use the crane to place it beneath the ladder path.
• Find the hidden cart near the elevator, move it to the marked spot, and crane-lift the nearby fuel barrel onto it.
• In the workshop, repair the lantern from the missing nearby parts.
• On the fog sea, keep speed low, avoid raising sails, and swap lantern colors as visibility demands.

Chapter 3: clear the lighthouse sequence in order

The biggest time loss in this part is treating the island like a freeform scavenger hunt. It is more linear than it first appears. If a door, machine, or control point seems dead, it usually means you are one step early rather than missing some deeply hidden item. That matters because the chapter ties several small environmental interactions together: the code lock, the generator, the beacon, and the later navigation setup.

As you move through the island buildings, pick up cassette tapes when they are on your natural path. They are easy to miss if you rush, but it is also not worth derailing the main route for them if you are currently stuck on progression. The better habit is to clear each reachable room thoroughly before moving on: shelves, benches, and obvious interactables first, then the next machine or door.

Use code 314 when the puzzle flow narrows

If you have reached the stage where the game clearly wants a numeric input, the code you need is 314. This is one of those moments where overthinking costs more time than the puzzle itself. Enter the code, move the sequence forward, and only then continue exploring newly opened areas. If you are still locked out after using it, double-check that you are at the intended keypad or lock for the current objective and not revisiting an earlier dead end.

Restore generator power through the barrel elevator setup

The generator portion is easy to misread because it looks like a simple switch problem, but the solution is logistical. You need to use the fuel-barrel elevator setup to get the generator running. In practice, that means focusing on how the barrel reaches the machine instead of hunting for another lever. Once the barrel is in the correct place and the power puzzle is resolved, the rest of the lighthouse chain starts making more sense.

After power is restored, complete the beacon step and pay attention to the navigation information tied to it. The chapter also uses a radio frequency, 120.5, as part of the broader route forward. Even if the game does not make the relationship between these systems feel especially elegant, the important point is that lighthouse power, beacon setup, and radio guidance belong to one connected progression line.

Crane puzzle 1: place the crate on the chalk mark first

When you reach the loading area, stop looking for a hidden ladder route. The first crane puzzle is about floor positioning. Take the initial movable crate and push it onto the chalked ground mark. The chalk is the game’s way of telling you where the crane can properly line up the load. If the hook action seems wrong or the crate will not solve anything useful, it is almost always because the crate is not centered on that marking.

Once the crate is in position, operate the crane to hook it, lift it, and lower it into place so it creates access to the ladder route above. After that, climb onto the crate and use it to reach the upper level. The reason this works is simple: the crane is not just moving clutter out of the way, it is building your platform. A lot of players lose time trying to place the crate near the ladder by hand when the puzzle expects the crane to do the final placement.

If the scene still looks unusable, step back and check the full vertical route. These puzzles are easier to solve when you think in elevation changes: floor mark, crane lift, new platform, ladder access. The game likes that pattern in this chapter.

Crane puzzle 2: find the hidden cart and move the fuel barrel

The next progression gate is not another random cargo shuffle. Near the elevator area, there is a cart hidden behind crates. Clear the obstruction, pull or push the cart out, and move it onto the correct chalk mark. Just like the earlier crate puzzle, the chalked spot matters because it defines where the crane can drop the next object with useful alignment.

After the cart is in place, use the crane to lift the nearby fuel barrel and lower it onto the cart. This is the step that opens the route toward the workshop and the lantern repair sequence. If you have been trying to drag the barrel directly to the destination, that is the wrong approach. The cart is the transport solution, and the crane is there to load it rather than replace it.

This is also a good moment to remember how WILL: Follow the Light communicates mechanical puzzles. Chalk marks, benches, carts, cranes, and elevators are usually part of one complete chain. If one object seems pointless, you are probably still missing the next piece of the chain rather than looking at optional scenery.

Repair the lantern before leaving the workshop

In the downstairs workshop, inspect the lantern on the workbench. It is not ready to use yet, and the missing parts are nearby rather than hidden across the entire level. Search the immediate workspace carefully, collect the pieces, and assemble them at the bench. The game expects observation here, not a wide-area hunt.

Once repaired, the lantern functions like the one from Chapter 1 but with an important twist: it now has fuel limits and color switching. The relevant colors in this chapter are red, blue, and yellow. That matters because the lantern is not just a light source; it becomes your navigation tool for the fog segment. If you leave the bench area mentally treating it as a simple flashlight, the next sequence will feel harsher than it needs to.

If the lantern repair does not register, re-examine the workbench after placing the last part. Coverage around the game’s launch noted occasional objective confusion, so one extra interaction on the completed device is worth trying before you assume something more complicated is wrong.

Fog-sea navigation: go slow and use the lantern deliberately

The fog crossing is where players often sabotage themselves by sailing the boat the way they would in a clear-water segment. Do not do that here. The safe approach is to move slowly and avoid raising the sails. The chapter’s core challenge is visibility and lantern management, not speed. By creeping forward, you give yourself time to read the water, identify rock shapes, and correct your line without burning fuel through unnecessary detours.

Use the repaired lantern actively as you move through the fog. Swap between red, blue, and yellow when the current color stops giving you enough contrast to safely read the route. The exact rock silhouettes can be hard to parse in heavy fog, so the goal is not perfect memorization; it is controlled movement and quick reassessment. If the water ahead suddenly looks blank, assume the problem is visibility first, not that the path has vanished.

The radio frequency 120.5 also ties into this navigation sequence, so keep that reference in mind if the chapter asks you to orient yourself through radio guidance. Between the beacon work in the prior section and the lantern colors now, the game is clearly asking you to think like a navigator rather than a speedrunner.

The chapter ends once you make it out of the fog and discover another boat. If you are close to the end, stay patient. A lot of failed attempts happen because players sense the segment is almost over and start pushing the throttle harder. That usually leads straight into a rock that was only half-visible a second earlier.

Common stalls and fixes

• If the crane puzzle feels impossible, check whether the crate or cart is actually on the chalk mark. Being slightly off-center can make the whole setup look wrong.
• If you cannot progress past the lighthouse section, verify that you used 314 at the correct lock and completed the generator power chain, not just part of it.
• If the workshop seems finished but the objective does not advance, interact with the lantern bench again after assembly.
• If fog navigation feels random, lower your pace. This section is tuned around careful visibility management, not fast sailing.
• If the route ahead becomes unreadable, change lantern color before changing direction. The wrong color can make obstacles much harder to judge.

What these chapters are really asking you to do

Chapters 3 and 4 are less about hidden-item hunting and more about reading the game’s mechanical language correctly. In the lighthouse section, that means following the chain from code to power to beacon to navigation data. In the loading yard, it means trusting chalk marks, cranes, and carts instead of trying to muscle objects into place. In the fog, it means giving up speed so the lantern can do its job.

If you keep that logic in mind, the whole stretch becomes much cleaner: use 314, restore generator power, complete the beacon setup, solve the two crane placements, repair the lantern, then cross the fog slowly with deliberate color changes and minimal sail. That is the route that turns these chapters from confusing into straightforward.
