Escape First 2: How to Complete Escape Room Factory

When you first spawn in, next to a medical cabinet will be 2 rows of 3 red buttons.
Enter in the the following:  Top Middle, Top Right, Bottom Middle

This will make Blue, Red, Green, and Yellow birds appear around the room.

There are: 4 Blue birds, 2 Red birds, 1 Green bird, and 2 Yellow birds.

Enter the code: 4212 in to the number pad located in the far left corner of the room.

Inside will be a power button and a note, however we are unsure what the note related to.

Before pressing the red button, turn towards the radiator with a mirror just above.

Turn the Red valve and this will reveal the numbers needed to unlock the next number pad.

Go to the number pad closest to the sinks, and enter: .4531

PRESS THE RED BUTTON 

You can now open the door of the fuse box, inside there will be a Gray button, and a Key hole.

Once the Fuse Box is open go to the other side of the sinks (next to the medical cabinet). Interact with the keys sitting on top of the pipe.

This will make the keys fall down the pipe.

Back at the fuse box, press the gray button.
Spawn in the Wrench, Crowbar, and Screwdriver.

With the Crowbar, break the chain on the Medical cabinet door.
(There will not be a white highlight when hovering over it, unlike the other interactables in the game).

Inside will be a pipe part, and a water bottle. You can either add the water to the pipe where the keys were sitting, or use the water bucket located near the radiator.

Use the Wrench on the bolt to have water leak into the bucket.

Once the water has been added to the pipe, go back to the fuse box and press the gray button until you get back to the pipe wall.

You now need 3 pipe parts:
There is 1 in the Medical cabinet, 1 in the toilet, and 1 on the floor directly outside of the toilets.

You will need to complete the pipe circuit so the air compressor links to the fuse box.

Once the pipe parts have been added, press the switch on top of the air compressor.
(Warning: this is very loud)

Go back to the pipe where the keys were originally, the keys are now on the floor.

You can now enter the keys in to the fuse box.

Press the Gray button until you get to the wooden door.

Click the wooden door.

Well Done, You have completed the Factory!
