"Roger that. Give us thirty seconds to reload everything first."

The bots follow her in when that time is up.

Inside the Memorial are high, but not very wide rooms and hallways. The main room has the turrets set up, as James said, but they are defunct. The main door to the purifier is still firmly closed. 

Between them and the door, however, are some very angry enemies.

And their pets.

The bots freeze for one and a half seconds, then concentrate fire on the super mutants and ignore the centaurs.

The centaurs don't take kindly to their masters being shot at. With high, gurgling streaks they approach in that slow, menacing, sickly way, tentacles slapping at bots, trying to get firm holds to drag them to the ground.

Amy focuses on them, managing to drop one, even as her heart clenches to think of Edward.

Okay then. Nick misjudged. Or something.

As soon as she starts firing at the centaurs the bots return to normal firing pattern: FIRE EVERYTHING AT EVERYTHING.

The centaurs don't flinch at all, and only stop attacking when they die.

The super mutants howl in fury to see the centaurs fall, and a small group charge forward, swinging sledgehammers of various kinds.

Amy lobs a grenade at the ones who stay back. The explosion relieves two of a leg, and the rest are knocked down.

The robots fall back while firing, trading ground for time. Flamethrower Bot stays, pouring fire over it all, playing a high-pitched laugh on a loop, and then the sledgehammer-wielders are upon it.

Amy nearly doesn’t see what’s about to happen, but catches it just as she downs another centaur, and dives back behind a wall, putting distance between her and the bot. 

“Godspeed, soldier,” she murmurs. 

Flamethrower Bot gets hit twice, three times, there's a gash in his fuel tank and chemicals are gushing out, catching on fire. The fire trails back up to the big tank and-

WHOOOOM. The fireball covers the entire hall, reaching almost to the top of the narrow room. A wave of heat and concussive force washes over everything.

That seems to be the end of the super mutants.

Amy braces herself as the wall she’s behind becomes almost unbearably hot. 

A few moments later, the fire dims, and the roar dies away. Amy gets up and heads back into the main room, saluting the pieces of the bot. “Your sacrifice is noted, and we are grateful, soldier.” 

“All right, the rest of you spread out. We need to double check this place before your boss can come through.”

Sarge Bot comments, "He'll get a medal for that show of courageous stupidity. Double-check that they're all dead!"

Amy heads over to the door and checks that all the seals are in place. It's remarkably solid for having withstood for nineteen years. 

"How's it looking?" Amy asks one of the bots once they start filing back into the main room.

"No further hostiles in area. Starting loot- Er, acquisitions detail. From the mutants only."

"Go for it. Let your boss know it's all clear."

"Looks like the loud and dangerous parts are over, bud. I lost a bot but his personality consisted of 'I like fire', so I can rebuild him."

“Is Amy all right?”

Edward seems to want an answer to that too. At least, his gurgles seem worried. 

"Maybe a bit singed, but walking and talking just fine. And there's no more super mutants. Go on in."

“You’re not coming?”

"Maybe in a few minutes. Leave my ship unattended except by a large number of turrets, in the wasteland? Bah. Call me paranoid, I don't mind."
