Modern Art Museum Overview
In Nightmare mode, the Modern Art Museum takes on a distinct twist compared to Standard mode. Instead of doors, areas are now connected through portals, all converging in the “Cloud Level” room, which serves as the central portal hub. While the layout shifts slightly with this new mechanic, the individual rooms remain largely unchanged. For reference, I’ll continue to use the Standard Mission map to guide you.
For clarification:
The rooms are numbered according to the sequence in which I entered them, prioritizing doors first, followed by portals.
1 Foyer 2 Ancient Exhibit 3 Bathroom 4 An Illusion of Choice Room
1 – Foyer
The Foyer serves as the expansive entrance hall, offering a glimpse of two green hands and a shimmering portal up ahead. To the left and right, two sets of closed double doors stand, granting access to the West Wing (Music Exhibition) through a locked Beige Door and to the East Wing through a locked Yellow Door. Note: The Garbage collection point is at the Cloud Level.

The Furniture Room, also referred to as the Red Room in the Standard Mission, can be reached via the white portal in the Cloud Level. This distinctive space is characterized by white furniture suspended from the ceiling, creating a striking visual. It now also incorporates the area formerly known as the Yellow Room from the Standard Mission. Once entirely yellow, this section has been transformed into a blend of blue and yellow. A double door within the blue and yellow area provides access to the Foyer when opened.
There are no further access doors.
