You find yourself in a sort of maze made up of several apartments connected via their front doors.

In the overgrown apartment, one of the doors is locked. You must find a way to open it.

It is also possible to take a look into this locked room from an adjacent room.

In order to find a way to open the door, you must explore four different apartments.

This is the version number of the retro console's internal software.

Some docks allow you to modify the version number. More specifically, to increase it.

Some of the retro console's features are unlocked as the version number of the internal software increases.

The highest version number that can be reached during this part of the game is version 1.3.

Batteries are used only to power other devices.

You can carry two batteries at the same time.

You will find the first battery easily while exploring the overgrown apartment.

To locate the second battery, you will need to understand why some objects in this apartment appear "unstable".

The videos show not only phasmids, but also several sections of the same outline.

You can pause the videos by interacting directly with the video projectors.

Pay close attention to each area's composition or look at the screens in the monitoring room to piece together the layout.

You can see the entire layout from a room in the apartment that's completely overgrown with plants.

Powered by a battery, the antennas cause phantom objects to appear, some of which seem "unstable".

You've probably already seen these phantom objects somewhere outside this apartment.

If you recall where you have seen said objects, you will find which codes to enter and in which antenna.

Enter the correct code in an antenna and observe the change that occurs among the phantom objects.

This machine also lets you save waveforms to your GameLeaf.

There are three slots you can use for saving waveforms.

To describe waveforms, Fael has developed several systems. He mentions the topic in his emails.

Saving a specific sequence of three waveforms on your GameLeaf will allow you to open the locked door in the apartment that's completely overgrown with plants.
