Access Tunnels

Try to flip the lever, but the elevator won't work. Open the hatch in the elevator ceiling and climb up. Climb up to the door above. Pick up the small coin from the ledge here. Examine the small access panel and use the coin to remove both screws. Open the panel to find a sliding puzzle - you just need to slide in the 4 large rods from the sides to turn the lights from red to green. Continue into the walkway ahead, where a steam vent blocks access to the left. Open the door at the end of the hall and go through.

You will find a crossroads here with signs to several new areas. Start by heading to the right, then enter the room on the right.

The door to the right leads to a flooded area, so continue straight ahead. Go forward into the main lobby and take the red wooden cube from the shelving. Open the trash can to see a recipe for DIY fuel. Back out and go over to the TV. Open the cabinet beneath and take out the darts. Go over towards the bar and look at the whiteboard that shows the scores of a darts competition. Continue through to the kitchen and take the cooking pot from the right. Search the shelves on the right to find a blue wooden cylinder. Back out to the start of this hallway, and go right into the game room.

Pick up the pool triangle from the floor. Read the notice on the wall about how to set up for a game of pool (in particular note the numbers of the balls). Now examine the wooden cabinet on the wall. Put the darts on this cabinet, then you need to rearrange the darts according to the scores you saw earlier:

Look at the broken door on the floor and take the keycard. Back out and turn around. Pick up the crowbar from the yellow crate, then climb back into the vents. Your flashlight will run out of power - open it and take out the battery, then put it your new one. Go through the ventilation ducts to the right and into a new room.

Power Room

Go through the door on the right to be just outside the power room entrance. Examine the blue panel on the wall, and force it open with your crowbar. Take 4 colored wires from inside. Head back inside and go forward twice. Try the large lever on the left, but it won't work yet. Examine the panel on the right, which has five symbols that match the torn sheet of music you saw. Arrange the panel so the positions of the sliders match the relative positions of the notes with the same symbols:

When correct, the light at the top of the machine will turn green. Note the small blue safe here, which is closed. Back out, then look at the large console area to the far left. Look at each of the windows to see the paths of the colored wires. Remembering the equation you saw in the bedroom earlier, you need to copy the layout of the 4 wires in the appropriate windows (red A, blue B, yellow C, green D). Go to window E and insert your wires, then adjust their left and right attachments as follows:

Go back to the large lever and turn it on. Return to the small blue safe in the corner and take the wire cutters. Go back into the vents.
