Indeed!

The chamber is more complex than previous ones, with lots of buttons. The exit seems to not be naively reachable—it's higher up but there are no stairs. Furthermore, it's locked and connected to a large red button.

Okay...

What do the other buttons do?

The small one she can press makes a cube fall from the dropper onto the floor over there; the big one raises a set of stairs to the other level.

Portal to grab the cube, cube on big button, up the stairs.

As expected the big red button there opens the door.

Other buttons?

One of the buttons makes a second cube drop onto the slanted stone plate and fall into the goo, and the other makes the panels extending over the goo become vertical for a couple of seconds.

She has to put the portal underneath the other dropper, but if it comes out the orange one traveling at speed it's going to get launched right into the goo anyway. But the temporary wall will probably block it so- portal, cube button, wall button.

Works!

Hooray.

Onward.

"Well done! The Enrichment Center reminds you that although circumstances may appear bleak, you are not alone. All Aperture Science personality constructs will remain functional in apocalyptic, low power environments of as few as 1.1 volts."

The elevator chamber is up ahead! And the walls have holes.

What, they don't have internal reactors?

Holes she can get through?

She can prrrrrobably squeeze through, yes. The other side is pitch black though.

Hmm.

Can she put a portal in there?

She can try but the blue light of the portal goes as far as her eye can see and disappears into the darkness.

Why is this place so pointlessly fucking large.

Who even knows.

The elevator is still waiting for her.

If she gets in the elevator she's just going to have do another stupid "test" of basic spatial awareness fuck it too late she's already going through the wall.

It's dark. And she's falling.

At least she's not testing.

She can see looming shapes that resolve into walls, and shadows that become catwalks and glass tubes delivering cubes here and there. There are metal railings like the one the robot eye used to navigate, but no movement's detectable there.

She should probably try to grab something before she hits the bottom. Not that that seems likely to happen any time soon.

That catwalk is perhaps close enough...

This going to hurt a little bit. Good thing she's not heavy enough to rip herself apart.

Swing over and grab with as many limbs as possible-

The catwalk sways but holds.
