16. Zoom in on the lighthouse. Then tap on the left side to see a wooden box. Open it and take the antique key from inside. Also, tap on the spider web if you’re working towards getting the Spy-der Web achievement.

17. Go back around and use the key to unlock the lighthouse door. Head inside.

18. Grab the battery and the shovel. Also, tap on the two spider webs if you’re trying for the Spy-der Web achievement.

19. Go back to the boat and then back to the beach. Time to find some buried treasure! Remember the map? It was showing the fuel drums. Use the shovel to dig where you saw the X and then examine the hole. Take the rusty box.

20. Go back inside to the elevator. Take it to floor -1. There’s a few things to do here. I’ve highlighted them in the image below.

21. First, take a photo of painting 2/2.

22. Then, use the crowbar to knock over the statue and take the ornate gem.

23. And next, zoom in on the broken security pad by the right door. Place the spring inside to open the door and go through.

24. Now we need to shut off the lasers. The access code is color-based. Look at the two paintings we found and note down which colors are in spots where there are circles, not dots. You get: Dark Blue, Teal, Red, Orange, Light Blue, Purple. Now press those colors on the keypad to shut the lasers.

25. The antigravity field turns on. Take the hearts key and place the two gems you found in the slots on the device.

26. Get back in the elevator and take it to floor 0. Insert the spades key and the hearts key into the box. They’re the last ones, so it should open. Take the ornate gem from inside and take a screenshot of the pattern inside the box. Again, it’s different each game.

27. Enter the right room again. We have a few things to do in here. First, load the ammunition into the gun. Then use the gun to explode the watermelon.

28. Next, place the rusty box on the pedestal where the watermelon was. Shoot it and then take the machete from inside.

You can also shoot the gun 100 times to get the Target Practice achievement.

29. To the right of the gun is a battery charging station. Place the battery in the slot and then wait for the meter to turn green. Then take back the charged battery.

30. Go back to the lighthouse. Place the battery where you found it to power up the lift.

Can’t find chapter5

parivesh sharma

I don’t understand the spider web thing, nothing happning on mine.


Hi yeah, you said the final blueprint piece was under the jet pack, but I’m still missing a piece? What’s the other location for the 5 clearance blueprint piece?

Conrad Uno

Hey, same for me but I’ve just found it! I was also missing the clubs key from the hallway box which i know i got in ch4. So went back inside Ruby’s house upstairs to study and over on the shelves that the cat knocked was missing blueprint and club key. Maybe it was the update, just glad i can carry on. Hope it works for you too


Same here.


So I finished all the chapters and I think you all need to follow the cat footprints the upstairs part of Ruby’s house. I did that in chapter four and got all the blueprints.


how the f? I found only one blueprint at the start of chapter 5 like you. But I seem to have one missing still.


I was missing one too. Found it back in the house in the room with the phone and the phonograph. On a shelf by the red lever.


Thanks for the tip. I found the missing blueprint piece there too.


I got the bird on the log with a fish before I knew to take a fish to the cat. I keep trying to get another fish, but a bird flies away with it every time. I have the key for the pink -2 room, but my code won’t work and I’m assuming it’s because I haven’t given the cat the fish yet. Do I have to reset the whole game now?

I can’t move the spring on the security pad in floor -1


Same here.

I can’t find Spade Key


Me either


How do you get to the waterfall?


What is the trick to the puzzle to open the waterfall?


This is a hard one to crack I am still stuck on this


Is there a trick for the floor puzzle beyond matching it to the pattern inside the box? I’ve definitely matched mine but no box pops up for the key.


Check second from bottom tile, rotate it a little. It was a problem in my case


Has anyone solved the puzzle behind the waterfall?


Also stuck here. I did the puzzle and nothing happened.


Check second from bottom tile, rotate it a little. It was a problem in my case

Hi, I do not appear to have the rope, despite reading this I cannot find it, where is it?

Charlotte Evers

Have you found this yet? I’m missing it!


I just saw the answer to my question. Thanks!


where’s the floating box? I can’t seem to find it.

Ray snowden

I’m missing a ruby. I thought I got them all but one is still missing. Is there 3 or 4 Ruby’s? I’m stuck.


The one I’m missing is the top one. Where is this located? When I dropped the others in it went to its place.


Where do we get the second stone


Hi, I’ve started chapter 5 but I can’t find the lighthouse?
