"Okay, listen, we should get our stories straight, alright? If anyone asks—and no one's gonna ask, don't worry—but if anyone asks, tell them as far as you know, the last time you checked, everyone looked pretty much alive. Alright? Not dead," he continues, and then the room hits something. "Aggh, see, now I hit that one, I hit that one..."

So dead.

"Okay, almost there. On the other side of that wall is one of the old testing tracks. There's a piece of equipment in there we're gonna need to get out of here. I think this is a docking station." It is not a docking station. It is a wall. "Get ready..."

"This is not a docking station, you idiot! If you want to ram the wall, just say that!"

"What was that?" he calls over the noise—

—then, yes, rams the wall. "Good news: that is not a docking station. So there's one mystery solved. I'm going to attempt a manual override on this wall. Could get a bit technical! Hold on!" Ram.

What's the wall made of?

Concrete.

He draws away from the wall, accelerates towards it, ram. Draws away—" Almost there! Remember: you're looking for a gun that makes holes."

"And is it distinguishable from other guns in any way?"

"Not bullet holes, but—well, you'll figure it out. Seriously do hold on this time!"

Ram and the wall's destroyed.

Anywhere's better than staying in the idiot's box. She jumps through the former wall.

She lands on a glass ceiling which breaks on impact, leading her to a glass room with no doors.

Can she break a wall?

Nope! They are sturdier than the ceiling.

"Hello," says a different voice from who-knows-where, "and again, welcome to the Aperture Science enrichment center."

Can she grab that short stool and use that to smash the walls?

Yes! Smashy smash, at the same time as the announcer voice continues: "We are currently experiencing technical difficulties due to circumstances of potentially apocalyptic significance beyond our control. However, thanks to emergency test protocols, testing can continue."

Great, then she'll hop out of the room and take a look around. And float the stool along in her FCS in case anything else needs hitting.

"These pre-recorded messages will provide instructional and motivational support so that science can still be done even in the event of environmental, social, and economic or structural collapse," the voice says. The space around the glass room seems to be dirty and overtaken by flora, as if abandoned for several hundred years. "The portal will open and emergency testing will begin in three, two, one." And a strange noise comes from the room she just left.

The overgrown nature of the room seems fairly normal. Maybe a bit neater than usual, if anything.

She ignores the strange noise.

If she walks around the glass room to the other side she'll find a round double door.

And what's through the door?

A derelict room with a large red button on the floor and a lumpy cube in a corner where is seems to have fallen from a glass cylinder attached to the ceiling.

"Cube—and button-based testing remains an important tool for science, even in a dire emergency."

...machines are weird.

Can she pry open the door?

Nope!

Fuck.

Okay. Button?

She can stand on it and that makes the door open!
