Examine the phone on the coffee table to hear about your mission Undercover Mission. Look at the sticky note on the corner of the laptop screen, then go to the tablet on the opposite table and unlock it with the code #113113. This will show you part of a code (22672--), and a message about "Breaking News" on the laptop.

Just to the left, examine the box with the long combination lock, and open this with the code 2267226 (just repeat the pattern), then take out RAINI. Notice the number on the picture on the wall (5-3-). Go to the sliding blocks next to the sofa and slide them so that the numbers (5-3-) are shown at the very top - the highlighted numbers across the middle will be 1727. Open the key box on the other small table with the code 1727. Take out the key. Use this on the door and leave.


Notice a tool box on the ground next to an open dumpster. Pick up the metal pipe leaning against the wall (this turns out to be a flashlight). Open the dumpster that is blocking the stairs and take out the trash bag, then put this in the other dumpster. Now you can push the one blocking the stairs. Look at the sign on one of the shops on the right, mentioning the weights of various tools:

  • Saw: 3 kg
  • Hammer: 7 kg
  • Tool Box: 17 kg

Go back to the tool box and open it with the weight of all 3 objects combined (027), then take out the screwdriver. You can now get through the locked gate. Continue down the stairs and grab the dry cloth from the top of the mattress leaning against the wall to the left. Use this in the bucket of water on the other side of the stairs, then pick up the wet cloth. Use this to clean the side of the taxi blocking the next part of the alley, and you will see a number: 9129 (note the colors red, blue, yellow, green). Enter the taxi and notice the colors on the steering wheel (red, yellow, green, blue). You need to enter the numbers from the side of the taxi, re-ordered based on the steering wheel: 9291 Grand Theft Auto.

After getting back out of the taxi, look at the symbol on the bonnet. Go further into the alley and look at the bricks on the left wall. You need to press the 4bricks corresponding with the open circles from the taxi logo:

Head down the stairs.

Look at the sign on the left wall that mentions two dates 903-304. Subtract these numbers, and enter the code 599 into the keypad next to the door here. Enter the small room and take a door key from the open cabinet on the wall. Return to the main corridor and look at the laptop on the low table. Count the number of triangles in the symbol on the display (13), then enter this to unlock the laptop Hacker.

Follow the corridor around until you can unlock another door with your key. Look at the 5 circles on the back of this door once it is open. Back in the corridor, examine the large ticket machine. You need to press the buttons on the left of the ticket machine in the order indicated by those circles (filled to empty):


Grab the ticket, then use the turn-styles and walk through.

Subway Platform 1

Go over to the glowing panel on the wall and drag the pieces into these locations:

Head through the opened door. Notice a locked briefcase with a series of numbers on the lid here. The numbers in each row add up to 1000, so open the briefcase with the missing number (280). Take out the triangle button. Continue through to the next platform. Board the first subway car here and look on the seats to find a weekday service schedule. Also notice the large blue numbers written on the inside of this subway car (2, 4, 1, 5, 3) and the matching symbols on the outside (Triangle, Triangle, Triangle, Circle, Circle).

Inside the subway car, go to the left end and attach your triangle button next to the circle button on the wall. Press the buttons in the order indicated by the numbers and symbols on the subway car: Triangle, Triangle, Circle, Triangle, Circle. Go through the opened door into the next car. Look at the colored marks and numbers on the window to the right, to work out their individual values:

  • Blue: 4

A little further on, look at the diagram in the newspaper on a seat on the right - follow the lines to get the correct order of symbols from left to right (two lines, star, down triangle, up triangle). Continue to the end of the car and look at the keypad. Based on the colors on the EXIT sign, enter the code 4754. Exit the subway car and find an electrical panel that is locked with another keypad. The writing on the outside mentions Ridgewood 6-13. Using the information from the service schedule, 6-13 corresponds to 5:58, so enter the code 558. Grab the keypad button from inside the electrical panel. Also note the date of last inspection (03/12/2022).

Board the subway car again and go all the way to the far end. Look at the panel on the left wall and drag the 4 symbols into the positions you discovered earlier (two lines, star, down triangle, up triangle). Go through the opened door into the next car. At the far end, attach your keypad button, then enter the date you saw earlier as the code: 03122022. Go through the door and access the controls - you need to drag the colors to the correct places based on the subway map on the wall outside Train Driver:

  1. 5 × 4 − 9 = 11
  2. 3 × 5 − 7 = 8
  3. 2 × 6 − 1 = 11
  4. 4 × 3 − 8 = 4

Examine the laptop, which asks you for a code made up of triangles 2, 1, 4 and 3. Enter the code 811411. Now you need to find an IP address. Leave this room and go back up the stairs. Turn right and go up some more stairs, then use your crowbar to force the door open. Inside this room there are 4 columns of arrows. Each column corresponds to a number (draw the arrows end-to-end, starting at the bottom, to form the numbers). Enter the code 5739 into the keypad. Take the master key from the cabinet.

Leave this room and go to the far end of the hall, using the key to get into the first Staff Only room. Take note of the IP address on the wall here.
