Part 1: Island Solutions

The Islands are listed as what level they open on the lighthouse.

1st Island (Perspective Isle):
Once on the island, move over to the opposite side where a small dock is. You should find a triangle that can be picked up with the gravity gun. You will also see (looking towards the boat) that the small pole, solar panel, and boat, create a triangle. Bring this triangle over to the dark blue square by the generator.
Next to the generator you should see a roman numeral one. If you line up the green pieces on the poles (stand near the dock and look towards them), you'll see that they form a roman numeral one. This roman numeral one goes on the green metal square.
Finally, climbing the ladders in front of the generator will lead you to small lookout. Standing here you will see that the environment creates an orange roman numeral three. And up there is a roman numeral three you can pick up and place on the orange square.
Placing all three objects will open a walkway that rises from the water. Follow this to a newly opened cave and press the button. This island is complete.

2nd Island (Basalt Island)
Once you hop across the basalt pillars and arrive at the island, you will see a house and a painting on an easle. Go up to the easle. You will realise that it's missing a painting. Now head inside the house and find the correct painting. It is the only one that looks somewhat normal, it is a picture of the pillars outside. bring this to the easle and you will now know the combination. Interacting with the pillars will raise and lower them. All you have to do is mimic the painting and the generator will be activated. Run over to it and press the button. This island is complete.

3rd Island (Small Oil Rig)
head over and climb the ladder. On the outside of this platform you will see a crane. Interact with the button on it and the crane will pull up a cog. Bring this cog inside the oil rig. Inside this rig you will see two machines that need activation. First is the panel next to the door. On the opposite side of the desks you will find a plug. Bring this over to the panel and plug it in. Now the switches will have opened. Interact with these two switches and the gears on the other machine will start operating. Put the cog you fished out of the water in this machine and it will finish this island.

4th Island (Ships)
Swim over to these old ships and get aboard. Hop across them until the furthest ship. On this ship there will be a generator. Interact with it and it will pull the middle ship up from the water. Not surfaced, this ship will have a few barrels of oil on board at the back. Bring these to the first ship and refuel the generator where the light is. Once all three barrels have been placed here, the machine will start up and this island will be complete.

5th Island (Windmill House)
Run across the dock and at the back you will find a furnace which is burning. Grab the piece of wood right next to it and place it in. Continue to fill it up with wood (6 pieces total). After two pieces a windwill will turn on. Continue until all are on and the island will be complete.

6th Island (Large Oil Rig)
Jump off the small dock and onto the small boat. This works as a HL1 cart. Interact with the boat and move forward, this will start the boat. On approach, slow it and stop. Hop off and climb the rig. You will see a control panel with two buttons. The left button will disable (reroute) the electricity flowing into the water and you will be able to cross it. Press the left button and then grab the plug in the water. Plug it into the generator also touching the water. Now continue to the other side of the rig. All you have to do here is also plug in the loose plug. This will immediately start up the steam generators and the island will be complete.



Part 2: Lighthouse Solutions

This part of the guide will be for the inside of the lighthouse.

1st Floor:
Simply climb the ladder and press the button, this will break the grate and allow access to floor two.

2nd Floor:
Press the button and allow the kettle to produce steam and move the windmill which will open the door.

3rd Floor:
press the button and quickly get on the elevator, it leaves after two seconds.

4th Floor:
Press the button and it will destroy the object holding the ladder back. Now you can jump on the wooden crate and get to level five.

5th Floor:
Simply press the button and climb the ladders, the top should be open.

6th Floor:
Press the button and the elevator will take you to the top floor.



Part 3: End

Now you're at the top of the lighthouse, move to the spyglass which is setup looking at the Windmill House. You will see something in the ground. Run to the bottom of the lighthouse and grab one of the four shovels there. Bring this shovel to the Windmill house and to the ground on the right of the house. You will dig up a body and with it the key. Bring this key to the shack at the back of the lighthouse. Simply enter through the trapdoor and you'll be finished!
