You'll get teleported to a tower where you have to activate the 3 further devices first then return to the doorway and activate the device here. The monolith will awaken and you'll get an achievement:

It walks!


• Head back to the lighthouse. There's a photo on the front step. The desk on floor 2 has a statue, ritual disc (with the eye on it), and 3 notes to grab. Make sure to grab the cellar key off the chair as well. Floor 3 has a telescope you can look through. The roof has a note above the chair. You can take another note off the painting near the railing for an achievement:

• On eastern shore you can pick up 3 bottles, 2 shark teeth, and a disc key to access the north shore. Near the disc in a small altar you can approach for a vision. Heading up the nearby path behind the lighthouse has a meteor you can touch for another vision and an achievement:

Quite the reader


• When you reach the end, go right and find a creepy photo near the standing camera and then hop into the boat. Grab a photo and a small object that acts as a key. *After placing this, you get teleported away and cannot return to this part of the island. Enter the nearby cave and place the key piece in the altar.
• You'll be on another shore with a dead whale. Going past it, a creature will come from behind the whales tail and chase you into the cave. Halfway through it collapses and you're safe.
• Find a note outside and then grab the diver's suit. Walk on the ocean floor until you find a stone gate with 3 small pillars. Rotate the pillar blocks until the etchings line up and the gate opens, Proceed down towards the tentacles and jump into it's mouth.
• A creature in down here, all you can do is run. You'll meet another (harmless) creature that will kill the one chasing you. Pick up the Cthulu statue and you'll get teleported.

• To start off, move the camera to see where you are! You've lost everything except the artifact you recently acquired. Place it in the slot to open the way. A giant monster is slowly after you so only stop if you have to attack someone or want to see the monster. Once at the end, you'll see another creature here. Grab the nearby artifact, it's a weapon you can kill the creature with. You'll then get teleported away.
• Follow the path and beam the giant eye. Teleported again, follow this path into the twister then another teleport to a long tunnel section.
• There's 2 fast re-spawning creatures ahead. Try to run backwards while beaming them. if they die, turn around to check the path, then backwards again to beam the creatures. Beam the door at the end and enter a safe room.
• Take the hands from the statues, place them on the pedestals and proceed. Walk through the creepy head room, beam a gate open, and talk to the floating mask. Then you'll get transferred back to the island.
• Walk down the shore and approach one of the side pedestals. Push the 3 light rods in to generate a light ball. Put the ball in an eye socket of the hovering statue. Repeat x3. When all eyes are placed, create 1 more light ball and it will grow. Place that one in the floating ring facing the pillar. Do this again on the other side and then go beam the middle object to wake Dagon. This act is an achievement:

Dagon

• Start in a room with a calm creature and 3 spheres. Attack the creature to have it kill you for an achievement:

Nowhere to run


• To escape, beam both side spheres first then the middle one. Beam the symbol produced to teleport.
• Next room, find the head with a glowing symbol and place it on the body. Teleport.
• Walk through this tunnel and beam all the symbols then get teleported away.
• Beam the door open and proceed. You'll see an invincible creature ahead. Take the left path, beaming the creature to stun it shortly. Repeat this, and around the corner is a door on your right you can beam open and run through! It will close separating you and the creature. Run up and open another door and continue on.
• You'll enter a large area. Approach Cthulu, beam the symbol to wake him up. You'll get an achievement and then teleported.

Fhtagn


• Here, follow the path and grab the missing piece. Place it on a pedestal and swap the pieces as needed to match each pedestal. You'll talk to some monsters and teleport again.

• For this puzzle, approach each tower and rotate the small floating discs. Then spin the 3 hovering objects in the middle to release the artifact. Take it and you'll teleport away.


• Walk straight into the tunnel ahead and a big creature will be on the left. Run and open the spiral door with the pedestal, it will close behind you and you're safe in here.
• Stop the small cubes from spinning when the eyes line up to the big cubes. There's a small path up to a spiral door but I don't think it opens, just advance through the main one into all the arms.
• Run through avoiding them if you can because they do hurt you. Grab the suspended creature and continue on. The next maze-like room has a killable creature in the corner that will come after you. Place the little monster on the pedestal to open the 'mouth' door.
• This part has 2 fast creatures. Run backwards while beaming them and eventually they die. Proceed to the end room and beam the 4 eyes around the center organism. Spiral door will open.
• Next room a big creature will spawn smaller ones that come after you. Kill them with the beam while beaming the 5 lights in the room as well until they go black. Get an achievement:

It breads by itself!


• Interact with the ball of light under the creature you teleport.
• Here you beam all the eyes on the heads. Killable creatures spawn like the previous room but here it's multiple spots. Once all eyes are lit and no more spawns, you can present the artifact. Look up to see the gatekeeper monster.
• You'll be teleported again to a straight area (map below). Last story achievement:

Is he awake?


• All you do here is interact with each 'scene' for story stuff. The end has 3 pillars to touch as well and then game come to an end here.
