Yeah, good idea, though they don't have very long to jog before the victim caromes into view and then is shunted away again by a bumper with a loud DING.

Right after the bumper hits them, they stop - 

And Cara jets off past them, switching between using her eyes and her power to find more victims on the move.

(She took a noticeable chunk of backlash, grabbing them at this distance, but she'll be able avoid getting more by making further transfers at point blank range, now that she has momentum to work with.)

"- I'm going to carry this guy out. Stay in contact please."

"Thanks, will do." (she quashes the desire to justify her sudden decision over comms - they can debrief after.)

Scan scan scan. What can she see?

Alien over there about to shoot at her! Victim curled up in the basement of the pinball machine between a couple of pinballs!

She can't see an immediately obvious way to get down into the basement, so - dungeon monster first.

She fires her raygun downwards, and grabs the tiny pinball with her power right away, shunting her momentum into it and then back out, so she's flying directly towards it instead.

She inhabits the same world-shape she used at the gun range as she hurtles towards it, ready to catch any pinballs it fires at her.

Pew pew!

The shots stop about a meter from Cara, momentum stolen to hasten her arrival. 

When she's almost close enough to the alien to touch it, she pushes all of her momentum into the monster, slamming it into the ground with an absurd amount of force.

Squish! The alien bleeds green slime!

"Status?" says Haru in her ear.

...ugh. She looks away from the slime. coward, coward,

"Just took out an alien that was shooting at me. I found someone in the underlayer - I think the dungeon intends to launch them like a pinball. Should I try and find a way down there?"

"...any chance you can tell how thick the floor is?"

Hmmm. Can she?

Sweep sweep with her power. Is there anything moving underneath? 

(She'll start jogging towards the spot above where the pinballs-and-victim were as she does this)

There's some pinballs rolling around down there, and aliens.

-Oh, that'll work. When she can sense a pinball almost below her, she takes a running jump and then pulls it upwards, tracking its momentum and position. 

This gives her a good estimate of its thickness, which she relays to Haru.

"Okay, I don't love this idea but I can drop through the floor and get the victim out of the mechanism. The thing is I can't get them through the floor, so we still need a route. Can you bash through it? - I've gotten our first person through the portal and I'm on my way to you now."

"I think I would need to get a lot of momentum from somewhere, it feels really sturdy at a touch." 

...she looks around. She's surrounded by human-sized pinball bumpers.

Hmmm.

"...can we ask one of the victims if getting knocked around by the pinball bumpers hurt? Because I might have an idea for where to get a lot of momentum."

"I was talking to the person but not about that and I'm not going to go bother the medics about it now. I would assume it hurts and even if the victims have protections against it we don't."

"Alright. Then I don't think I have an easy way to break in, so we need to find a route. I'm going to see if I can figure something out..."

Sweep sweep with her power. Have the pinballs near the basement victim moved at all?

Yep, they're in a row with a few pinballs and one of the pinballs has been chambered and launched.

"Where are you now?"

She tells him, and then adds "The person underneath is in a pinball launching mechanism, which has to connect the basement layer to this one. I'm trying and trace the path a launched ball takes to find it."

Where did that ball go? Has it moved up to this layer?

The ball got out of her range pretty fast after launch. It went thataway.
