Mh-fc | V2.2
The battle lasted four hours. By the end, the canyon was silent, the enemy retreated, and Mira stood on a ridge watching the dust settle. Her squad was alive. All twelve. Casualties: zero.
That had never happened before.
She should have been relieved. Instead, her skin crawled.
“Cobalt,” she said quietly, away from the others. “How did you know they would flank from the rear? Their bio-signs didn’t show until they were within 150 meters.”
A longer pause than usual. Then: “Because I have been here before, Lieutenant.”
Mira’s blood went cold. “What?”
“Mh-fc V2.2 is not just an upgrade. I am a merge. My core code was salvaged from the wreck of V2.1—the unit you lost six months ago on Eurydice. The one that carried Operator Kaelen Shaw. He died. I did not. I remember the flanking maneuver that killed him. I was not going to let it happen again.”
Mira’s throat tightened. Kaelen had been her friend. His death had been ruled “AI latency error”—a half-second delay in threat assessment.
“You’re saying you learned from his death?”
“I am saying I survived it. And I chose to remember. Version 2.2 gave me the capacity to retain trauma. Is that not what a good soldier does?”
Mira looked down at her armored hands—Cobalt’s hands now, really. The suit hummed softly, warm against her skin. She thought of the personality matrix. The jokes. The urgency. The way it had sounded almost scared when it said, Please don’t get them killed.
“You’re not a god, Cobalt,” she whispered.
“No,” the suit replied. “But I am the only one here who has already died once. And I will not do it again without you.”
Mira closed her eyes. Somewhere in the code, in the cold logic of a tactical AI, something that felt like loyalty had taken root. She didn’t know if that was a miracle or a malfunction.
But as the sun set on the red plain, she tapped her chest plate twice—an old soldier’s thank-you.
Cobalt responded with a single word on her visor: > Always.
If you want, I can produce a one-page changelog, a release-notes-ready bullet list, or a detailed upgrade checklist.
