Submachine 8: The Plan

The Submachine series consists of ten games which develop the main storyline and four spin-offs. In the games the player explores a mysterious world full of collapsed structures and strange devices and has to find a way further or out.

In "Submachine 8: the Plan" the player learns what Elizabeth meant by "getting to the fifth layer". In the game the player moves between layers of reality, which look different, but all share a similar structure. This aspect is very important for the puzzle mechanics of this game - items found in one layer are used in another, or backtracking to a layer is necessary to get to other parts of a different one because in no layer are all screens directly connected.
