Chapter 3, Ruby’s Trap:

1. Zoom in on the briefcase. It’s locked, but there’s a hidden button behind the handle. Press it to reveal a puzzle.

You can also watch my walkthrough video for the whole chapter here:

2. You need to slide the circle, square and triangle pieces into the correct slots. To do so, first get the two diamond pieces to the left so you can slide the circle to the right. Then, side the two diamonds over to where the circle started. You should now be able to get the circle over to its slot, then the triangle, and the square last. The briefcase unlocks and you can open it!

3. It turns out she strapped a bomb to a bridge and now you have to disarm it! Your new mission is to hit the kill switch. Start by picking up the pencil and looking under the corner of the note for a clue.

final-1491

4. Open the right panel and flick the switch to open the left panel. Take the electronic chip and glowing object. Then place the electronic chip on the empty slot on the right side to hack the circuit board and get the power cell. While you’re there, also notice the clue.

5. Insert the power cell into one of the slots around the big red button. We still need three more, but this opens a small panel on the front of the pedestal.

final-1495

6. You need to tap the blue buttons on the center piece to extend the arms one or two times to match the cutout that’s spinning around it.

final-1496

7. Three new panels open. Let’s start with the one on the front. It’s basically a trial-and-error puzzle. You need to open each lock in the right order so they stay open. You can follow the image below if you need help. The panel will open and reveal some more buttons and locks that we can’t do anything with yet.

final-1497

8. Look to the left side of the pedestal. There’s a crank handle jammed in the fan. Take it and a small door will open. Pick up the glowing object and all the little plugs from in there and off the floor. Also, make note of the clue.

9. Go to the holes on the right wall and place the little plugs in the holes in the same 7 pattern you saw on the paper with Ruby’s lipstick. It’s the right pattern, but nothing happens.

final-1515

10. Zoom out and look at the security camera for the third of a set of clues, as well as a separate clue.

final-1516

final-1543

11. Go to the front of the pedestal and use the three clues to figure out which buttons on the keypad to press. The game will outline sections of it for you to make it easier.

final-1520

12. Don’t pull the lever down yet. First, we’re going to look for Trevor the mouse. Find him in his little hole to the right. The next part needs to be done quickly or it won’t work. Tap him so he runs to the other hole. The second you see him pop out of that hole from a distance, pull the lever down. Now he should be in that hole, as both versions of the room share that hole. If he’s not there, change the room back and keep trying until you do it fast enough. It can be a bit tricky. Then tap him again and he’ll run to a hole in the wall across. Find it and get Trevor’s key.

13. Use Trevor’s key in the keyhole on the floor near the right mouse hole. There’s another puzzle like the one earlier, only this time it’s a bit trickier. Match the piece with arms to the cutout to reveal a little socket.

final-1528

final-1529

14. Place the crank handle in the socket and turn it until the whole disc glows green.

final-1530

final-1531

15. The camera will now automatically show you the lights on the wall, and the 7 pattern will light up, but backwards. That means we need to go back to the original room and place the little plugs in the opposite direction.

Having that problem now. Every pin I drop it just says “that didn’t work”. I saw a keyhole in the floor in front of the “holes” but I haven’t got/can’t find a key to fit it. Super frustrating

SOS I’ve found all the clues but can’t get to the second power cell, is it because I didn’t respect a certain path? I did get the lights reordered, moved to the spy room, turned that crank the wheel got bluish, to then try to grab the power cell but the little trap won’t open, it’s been days I’m stuck going back and forth between the two rooms repeating this operation. In the meantime I’ve found other clues and a 3 cell but I need to get the 2 out! What am I doing wrong?

I think it’s a great walkthrough, but not always clear. I’m driving myself mad trying to get the lasers in position, and I don’t even know if that’s what I’m SUPPOSED to do. Could you consider making a YouTube channel like this? I would watch it often. I don’t want to be negative, I’m just frustrated. If anybody could help with the lasers part, I would really appreciate it! Thank you!
