Plenty of time to blast them all later. After they won't be immediately replaced.

Means she's back to being more surrounded, for what that's worth. But after making some progress, she can see where they're coming from. It's definitely not a converted preexisting building; this one is all metal and heavily fortified. Robot armies march out of the open gates, but there's no easy way to tell if they're leaving a garrison or are actually being built in real time.

Metal walls don't present any more of an obstacle than other sorts. She'll go in on the far side of the building from the gates.

The gates on this side are closed. And subsequently irrelevant once she's inside.

It's more of the same. Mostly bipedal, some variants, and the same types of weapons. There are in fact robots being repaired, but it's slower than the rate she's been destroying them and the repair drones aren't building more from scratch. She's been making progress after all.

Aha. Good. Then she can get to work on destroying these repair bots.

They go down easily. It's a sensible priority, but it eases up the pressure on the ones currently trying to kill her. A hail of what looks like lightning arcs toward her from most directions.

Not good. She retreats back through the still-open tunnel.

As long as there's a tunnel it also contains bullets and the a few grenades. Apparently the robots weren't going to use those indoors. When the tunnel disappears, the blasts from both both sides of the wall and inside it leave a more permanent hole.

Very very not good. Lightning is preferable to grenades. Back to the enclosed space. Not the same room that just got a hole blown in it.

As soon as she's inside the explosives and bullets stop. Missed lightning shots hit the thoroughly grounded wall, regardless of whether they're hers or theirs.

Time to keep moving again. Maybe she can find some sort of command center in the building.

On the way, she'll thin out their numbers a bit more. (The robots aren't terrible shots, probably, but they're very predictable. A split second to register her location, another to aim, and if she keeps moving she can usually be gone by the time she needs to be.)

A few tunnels later one of the rooms is entirely empty for no obvious reason. A voice comes from a hidden speaker. "You've really put a dent in my army, you know that?"

She starts, looks around for the source of the voice.

"Your army?"

"Robot armies don't just happen, you know. Congratulations, you got farther than any other heroes. Though to be fair I don't think either side is seriously trying usually."

The ceiling retracts, and a human descends. He's flanked by a squad of robots similar to the ones she's been evading, and wearing a matching suit of fairly basic power armor. He gestures, and the machines open fire.

Ellie dodges to the side while he lightning shade returns fire.

These are much less mechanistic about it than the earlier ones. They move like extensions of the tinker's suit more than as autonomous drones. He leads them out of the direct line from wherever she puts her shade, but doesn't seem to be doing anything analogous to help them shoot at her yet.

Then several of the machines blast straight down and plant long metal poles through the floor, angling them toward her. Lightning grounds harmlessly through the rods, and they take aim with ordinary bullets.

The lightning shade repositions so that the rods aren't directly between it and the tinker, while Ellie ducks through the wall again, closing the tunnel immediately after herself.

And the other side of the wall contains ranks upon ranks of robots, already set up with lightning rods and already firing.

They aren't terrible shots. And there are a lot of them.

Too many, too many-

Keep moving-

If she can get closer to the tinker she can at least kill him before she dies-

She can run back through the wall and that doesn't exactly help...

 Everything is bathed in a golden light. The machines don't stop, but they get silenced and shut down with a beam from the newcomer's hand. Ellie can hear others still active but none in the immediate area. Her opponent is more confused than anything else; what is Scion doing here, doesn't he have kittens to rescue or something?

The golden man swings an arm, not bothering to make a fist, and the tinker slides across toward Ellie. His suit sparks and hisses and is obviously at least partly nonfunctional.

Scion looks around, barely acknowledging Ellie, and then flies off to explode a few more helpless machines.

What.

And then she recovers herself enough to lunge down and grab the tinker, reach out for his power and rip it away.

He's not totally out of fight yet, and a partly-functional set of power armor is great for grappling—

but he's really not expecting an instant death touch.

There's a brief flash of something enormous floating through space, and then—
His power is exactly as impressive as it probably looked to the heroes. Not a lot of variety in what it can make but perfectly capable of machines building machines. Easily overwhelming with a little buildup time; presumably that's what happened here.

Oh, oh this is nice. She is going to have some fun with this.

...Though she should check if Scion is still in the area first.

He's out of sight. Notoriously hard to track, but at least she can't see him at the moment.
