Chapter 3:

You can watch my video for Chapter 3 or continue below for my step-by-step guide.

1. Xochi and Peter are trying to get Professor Burns to Dr. Okoya’s lab. We need to delete their records of the group. First, open the trunk of the white car and grab the windshield scraper. Move aside the pot of tea and grab the plastic sheets. Also, take a look at the army propaganda posters on the wall.

2. Use the windshield scraper to remove the army posters and reveal some symbols.

3. Look at the plastic sheets in your bag. Slide them around so the different sets of symbols line up properly. Focus on the symbols on the wall. The first two symbols are visible in my first photo as N and O. In the next photo you can see the symbols for C and T. Then in the next photo you can see I and the last one shows you S. So you end up with NOCTIS.

4. Enter NOCTIS into the locked box to open it. Take the sleeping pills and remote control from inside.

5. Give the sleeping pills to the tea merchant and he’ll make you a cup of tea with them.

6. Give the tea to the soldier with the laptop and he’ll fall asleep. Now we can access his laptop, but it’s locked with a passcode. Notice the pink and yellow squares above each number. Use the remote control on the lights above the gate and note down the pattern for each of the fives sets of colored lights. Now, look at the laptop again. For the first number, there are two pink boxes. So count up the pink lights in the first set of lights — 6. The second has a yellow box and a pink box. So count the yellow lights on the left and the pink lights on the right — 4 + 4 = 8. Do the same for the third number — 2 + 2 = 4. The fourth number is two yellow boxes and it’s 6 again. And the fifth number has yellow and pink again — 1 + 1 = 2. So the code is 68462.

7. Enter 68462 into the laptop to unlock it. Then delete all three files on Xochi, Peter and Professor Burns. The soldiers will let Xochi and Peter through.

8. Now we need to solve the Desert Navigation puzzle. We need to drive the jeep to the lab without running out of fuel. You only have 6 units of gas and you can refill at a gas station. You can also use a radio tower to make a soldier move to a different node. You can use my video if you need help.

9. At the lab, Dr. Okoya tells them that Professor Burns has been possessed by all the spirits of the Zerzurans who perished when Zerzura was destroyed. We have to help her unlock the box containing the Scroll of Mot that can help him. Pick up the tweezers and the photo of Burns and then the small key.

10. Use the small key to unlock the cabinet and grab the candles and chalk. Then place the candles and chalk and the photo of Professor Burns on the table. Go through the doorway to the submarine.

11. We’re going to use the little underwater drone to look for the missing masks. First, grab the pool net and the mummified head. Also, notice the word MALYEHNEDZ on the submarine and look at the map on the peg board.

12. Now let’s unlock the combination lock on the drone. The clue is MALYEHNEDZ from the sub. Break it up into pairs of letters — MA LY EH NE DZ. Now find those locations on the map. MA is Morocco, LY is Libya, EH is Western Sahara, NE is Niger, and DZ is Algeria. Now look at the lock on the drone. The first number is green and there are 2 green thumbtacks in Morroco. The second number is yellow and there are 4 yellow thumbtacks in Libya. The third number is green and there are 2 green thumbtacks in Western Sahara. The fourth number is blue and there are 4 blue thumbtacks in Niger. And the last number is red and there are 3 red thumbtacks in Algeria. So enter 24243 into the combination lock on the drone to open it.

13. Take the uncharged battery from the drone. Use the pool net to fish out the ID card from the pool. Charge the battery in the charging station. Then use the ID card to open the locker and take the lab journal. Look at the diagram of the teeth inside it.

14. Place the charged battery back in the drone. Now let’s use the drone to retrieve the mask underwater. You can watch my video if you need help with the Drone Diving puzzle.

15. Go back to the other room and tap on the X-ray machine. Place the mummified head down on the scanner to see that it has four false teeth. Now we have to figure out how to use that information to unlock the treasure chest. The way to do it is focus on the four false teeth. Notice that the 10 teeth in the x-ray are the ones in the middle shown in the journal. So they go from 4 to 13. The false teeth would be 5, 8, 11, 13. So just use the combination lock to write out those numbers, using the symbols in the journal as a guide. Then take the mask from inside.

16. Place the two masks with the others on the table and then use the tweezers to pull a splinter off of each.

17. Now go to the mass spectrometer and analyze the wood samples.

18. Now we need to use that information to figure out where to place each mask. Basically, the wood with the highest percentage of radiocarbon decay would have no trees with leaves, and then work your way up from there. It should look like the photo below in the end. Then grab the Scroll of Mot.

19. Use the scroll on Professor Burns and then watch what happens. The souls of the Zerzurans declare war on Atlantis!

And that’s the end of Chapter 3! Click here to continue to Chapter 4 or choose a chapter below.

    Came here for the part just after where you stopped, then realized you just posted this today and are probably still figuring that out. haha Hope you get it soon! 😊

    1. Julie

      Same lol, meant I had to persevere and solve puzzles myself

      1. Lexi

        It actually ended up being pretty easy, until Atlantis…. haha Had to get outside help for a math puzzle there, but still enjoying the game! Took a break to sleep. ╬ô├½├¡Γò₧├åΓö£ΓöÉΓö£├í I think I’m on chapter 7 now.

        1. Tiffany

          I need help on the first part of Atlantis, where the symbols open the door. I canΓÇÖt figure out the cipher

          1. Mm

            Atlantis welcome door equation, the rock outside in the water, each symbol starting from RIGHT to LEFT doubles…1, 2, 4, 8. The – is equal to zero
            So values of each symbol from Left to Right are 8, 4, 2, 1
            On the window sill count each of the symbols on the door lock, from top to bottom the #s are
            9, 1, 7, 13

          2. Lexi

            The four spaces are represented by four specific numbers: 8/4/2/1. Put a triangle in the space and add those numbers together to get the answer you need. The first number you need is 9, so you’d put ╬ô├½├¡Γò₧├åΓö£Γòó╬ô├▓├ª–╬ô├½├¡Γò₧├åΓö£Γòó╬ô├▓├ª. ╬ô├½├¡Γò₧├åΓö£├╗Γö£ΓîÉ The numbers you need are all on the thing you put water into on the left of the room.

        2. Mm

          Math equation please

    9. desert navigation: there must be something wrong here. ItΓÇÖs impossible to solve. Radio towers can only be used once as well. Soldiers move one spot away. This leaves no options. Please help.

  3. F. Brown

    I figured it out..

  4. Anchester

    I’m at Chapter 4 now, trying to figure out the best combination of trades, gets me a headache to find the best combination. For the parachute, I didn’t have enough time to figure out final puzzle, so I skipped it 😅

    1. Anchester

      I finally got the trade puzzle lol

      1. E

        Howwwww? IΓÇÖve been stuck for ages.

        1. Devin

          Me too

          1. Lexi

            I put in whole numbers that were in between the two numbers on the map, then just kept clicking through the numbers after the decimals. I’d switch the bottom number, then click through the top numbers. Keep doing that until you get the star. I can’t remember what they ended up being, but it didn’t take long.

      2. B

        Same tried basically every combination before I got it!

  5. Mm

    Chest puzzle, use the name on the submarine, each 2 letters represent a country. Count the colored pins in order of the colours in the chest.
    MA = 2 green, LY = 4 yellow ….

    1. Mm

      Sorry, meant to say this is for the sub cell, not the chest

  6. Madison

    Has anyone figured out how to do the coordinates on the plane?

    1. Devin

      Find the average

  7. Melissa

    How do you get the guards to move in the puzzle with the jeep?

  8. Pradnya

    Can someone please explain the puzzle with pink and yellow traffic lights?
