Dimhaven The Lost Source Full Walkthrough – Part 2

Welcome to the Into Indie Games walkthrough for Dimhaven: The Lost Source.

In Part 2 of Dimhaven: The Lost Source, Emily explores Bay Tower, collecting important items such as the Medical Access Card and a rubber tube while piecing together clues from a map puzzle.

After siphoning fuel from an abandoned boat, she powers up the island’s generator, restores electricity to key areas, and lowers a ladder leading to a bird’s nest where she finds a missing lever. This allows her to activate the payphone and receive a mysterious call.

Emily then unlocks the Ambassadorial Lavatory, spends her collected Forints on snacks to lure away the bird that stole her passport, and completes several photo challenges around the landing bay.

The chapter concludes with her reclaiming her passport, reaching the final visa checkpoint, and obtaining a clean sponge needed for future puzzles.

Inside the Bay tower now, open the cupboard and pick up the Rubber Tube.

Check the notice on the cupboard door. You will see the code format for the Ambassadorial Lavatory.

We picked up 3516 from the Visa Office earlier. We will check the calendar there later for the date for Wednesday.

Check the top right drawer on the desk for a Medical Access Card.

You will see a cut-up map on the desk. This is a jigsaw puzzle.

The trick to this is to line up the white edges first. Then go by shape, so that the completed picture looks like the screenshot below.

Turn it over and read the note. Now leave the Bay Tower and head back to the landing zone and past it to the locked gate.

Photo Challenge: A Rebel

You will find a bunch of sea gulls here. One is sitting on a “No-Seagulls” sign.

Go to the boat at the back and stick the rubber tube in the fuel tank.

Then, set up the petrol can we picked up earlier at the bottom. This will get you fuel for the generator.

When this is done, pick up the full petrol can. Go back to the generator in the lavatory area, refuel it and start the generator by pulling on the cord.

Go back to the tower near the bay tower, press the lower ladder button next to the broken switch to lower the ladder on the side.

This will lower the ladder on the side. Climb up the ladder and at the top you will find a nest which has the Broken Off Lever.

To open the door to the room on the right, you need to line up the grooves on the lock:

Once the groove is aligned, just unlock the door. Crouch and enter the small space and unplug the cable.

Photo Challenge: Zack’s House

Whip out your camera out and look to the left towards the horizon, you will see a black and white mansion.

Head back to the lavatory area and go through the small crawlspace to find the switch with the missing handle and insert the one you just picked up.

Pulling it will power the payphone we saw earlier and you will hear it ringing. Answer the call to have a conversation that is quite weird.

Anyway, its time to unlock the ambassadorial lavatory. The code is 1984+25+02+3516, therefore the final code is 5527.

Inside, check all the plaques on the walls. From the last one you can pick up 50 Forints. This should bring your total available Forints to 170.

Go to the vending machine near the Visa Office. Deposit 170 Forints and press 09 to get the red Sinister Snacks packet, which is the same one we saw in the nest up on the tower earlier.

Throw the snacks to the bird now to retrieve your passport. The bird is sitting on some cinder blocks near the visa office entrance.

Photo Challenge : Someone’s Lunch

If you take a picture of the bird eating the nut mix, you will get this challenge done.

Photo Challenge: A Sleepy Cat

Go through the turnstile now and you will see a cat sleeping on a bench.

Go up the stairs and check the lighter gun behind the coat and underneath you can find a code.

Take a photograph and leave it. Press the button on the wall that says Do Not Lean. Go inside to the final visa checkpoint.

Sit down and pick up the Dirty Sponge from the planter on the left.

Take the Dirty Sponge to the sink with the broken mirror and clean it to get a Clean, Wet Sponge.

Photo Challenge: Someone’s Breakfast

Go back to the Bay Tower and take a picture of the canned tomatoes on the window sill on the right.

That should complete “A Keen Eye For Detail: Complete the photo challenges in the landing bay” achievement.
