## Walkthrough

To progress through this level, you will need to follow a series of steps. First, read the message on the wall and then move the doormat to find a red key. Use the red key on the red door lock and head through. Throughout this level, you can use the map to help find your way around.

Once you are through the red door, turn left at the intersection and look at the panel next to the locked door. Through trial and error, you can work out the correct code to enter the store room. Once inside, examine the locked container on the wall and turn all the lights green to open it. Inside, pick up the black key and search the shelves and the trash on the floor until you find the matches.

After leaving the store room, use the map to head towards F2 and use the black key on the black door lock to enter the lounge room. Here, solve the picross puzzle and examine the chess board to work out which moves were made from the start of the game. Enter the code found on the note to open the locked box and take out the blue key. Unblock the other door so you can exit the lounge back towards the main corridors.

Head left and examine the puzzle on the door here, solving it based on the picross puzzle. Enter the gas feeding room and turn all 3 valves to the left. Open the cabinet and pick up the spare valve. Walk around the corridors and turn all 6 available valves to the left, then head towards the power room. Attach the valve near the fire and turn this valve to the left.

In the power room, open the green cabinet with the blue key and look at the computer screen to find out the 4-digit code needed to operate the right power board. To find the code, count how many of each item is present in the room, including the ones on the shelf. Once you have the code, move the yellow handle to turn the individual fans on or off. Start by setting the handle to position B2.

To disable fans F2, go out towards F2 and pick up a wooden pallet. Throw this in the water near fan F2 and move the other pallet as well. Pick up the red lever arm and return to the power room to attach the lever arm, then pull it down. Next, set the yellow lever to position C2 to disable fans F4 and F5.

Open the medical cabinet and take the yellow key from inside. Unblock the door here and go through to return to the main corridors. Return towards the gas feeding room and use the yellow key on the yellow door lock, then enter a store room. Pick up the red propane tank and return to the ventilation room. Use the propane tank on the brick wall, but be aware that the large fan above will blow out your match.

To continue, go to the power room once more and move the yellow lever to position C1 to disable fans F6 and F7. Go back to the ventilation room and head through the stopped fan on the right. Climb up the ladder and examine the fan controls. Adjust each of the settings to overload the circuits. Once the system explodes, the fan will stop spinning.

Climb back down and return out to the ventilation room. Use a match to light the propane tank, then go through the opening. Light the torch on the wall and examine the 4 statues around the room, then examine the dial in the middle. Position the small statues according to the compass directions on the bases of the large statues.

Go through the open doors and light the fire in the middle of the room with your final match. Look at the note and the map, and take the pass. Pull the two torches on the wall. Finally, go through the exit door and make your way out to your car. Drive away.
