Regressed with Omnipotent AI on Zombie Apocalypse

BAM! Bam! Bam!

The echo of heavy footsteps reverberated through the basement as Zack moved within the confined space. His tests were basic—simple movements and strength checks, all suited to the cramped area.

“MV-01 armor, second trial…” Zack called out. “Basic functions are operational.”

Ego, his AI assistant, responded. “All systems are reading normal. I recommend moving to an open area for further testing.”

Zack shook his head, grinning as he fastened the helmet. “No need for that. Let’s get to the real test—time to clear out the zombies in the nearby Mansions.”

He moved toward the elevator. As he did, Ego ran a final self-inspection, reporting the status of each system. “Helmet is secure… air circulation active… buffer system fully operational…”

The checks completed just as the elevator doors slid open, and Zack stepped onto the ground floor. Sophia was already waiting by the elevator, anxiety written across her face. She’d heard the ominous rumblings echoing from below and couldn’t shake her worry about what Zack had been doing down there.

Ding!

The elevator doors opened, revealing Zack, now a towering figure encased in gleaming metallic armor. Standing over two meters tall, his presence was imposing. Sophia instinctively took a step back, wide-eyed with a mix of shock and awe. Seeing an armored giant in movies was one thing, but seeing one in real life was an entirely different experience. The power and size of it were hard to believe.

“Don’t worry, it’s just me,” Zack’s voice came from within the suit.

“Za... Zack?” she stammered, her voice tinged with disbelief as she looked up at the narrow visor of his helmet. “This… this is what you’ve been working on down there? Armor?”

Zack chuckled, lifting the mask to reveal his face. “Yeah. So, what do you think? Impressed?”

Sophia’s jaw dropped. “Impressed doesn’t even begin to cover it! This is… this is incredible!” Her voice shook as she spoke, still struggling to grasp that Zack had built this suit in just a matter of days during an apocalypse. Such a feat seemed impossible even before the world fell apart.

The corners of Zack’s mouth twitched into a small smile. “Glad you like it. Who knows, maybe someday I’ll make one for you too.”

Her eyes lit up with hope. “Really?”

“Of course.” Zack nodded. And he meant it. With Ego’s database, he had access to blueprints for all kinds of power armor. Any one of them would be more than enough to protect Sophia in a world overrun by zombies. But for now, there were more pressing matters. “Stay here, alright? I’m heading out to clean up the area.”

As he lowered the helmet back into place and began walking out, Sophia called after him, “Be careful!”

“Will do.” Zack nodded confidently and stepped outside.

The HUD inside his helmet lit up, displaying the Mansion occupancy data that Ego had gathered earlier, marking the locations of the other residents—now likely turned into zombies.

“Let’s start with the nearest one,” Zack said, setting his sights on the closest Mansion.

Every step he took echoed through the empty streets, the heavy sound of metal striking the ground. Despite the suit’s bulk, he moved with surprising speed, almost like a human tank. As he neared the Mansion, the sound of his approach stirred the zombies inside. Their snarls and roars reverberated as they stumbled toward the windows and doors.

“Tired of living, huh? Oh wait, I forgot—you’re already dead.” Zack muttered with a smirk.

Without hesitation, he pulled back a massive armored fist and smashed it into the front door. Boom! The door shattered, splintering inward and slamming into a zombie lurking behind it. The impact split the zombie’s body in two. Even in pieces, the creature clawed at him with frenzied desperation.

Unfazed, Zack stepped over the half-zombie and into the Mansion. With a heavy stomp, he crushed its skull, silencing it instantly. Two more zombies lunged at him—one large, the other small. They had likely been a mother and child in life. A cold resolve flashed in Zack’s eyes.

“Let me end this misery for you. Rest in peace, together.”

The suit surged forward, plowing into the zombies with the force of a freight train. Boom! Boom! Both zombies were knocked back, crashing into the wall with enough force to crack the plaster like shattered glass. Zack wasted no time finishing them off, each punch sending them to their final resting place.

Once the Mansion was cleared, Zack dragged the corpses outside to his vehicle—a sturdy Ford F-150 Raptor. The bed of the truck had been converted into a makeshift corpse hauler. He tossed the bodies into the back, stacking them on top of each other.

“Alright. On to the next one.”

Pushing the heavily loaded truck, Zack moved from Mansion to Mansion, clearing each residence of the undead with methodical precision. Each encounter was quick—a series of thuds and crashes, like a macabre symphony of destruction.

By the time he exited the last Mansion, the truck bed was overflowing with bodies, the pile now towering high. Even the cab had become a gruesome storage space.

“It’s done,” Zack murmured, a sense of satisfaction settling in. He pushed the truck out of the neighborhood and into an abandoned construction site.

There, he poured gasoline over the truck and its grisly cargo. With a flick of his lighter, he set it ablaze. The flames roared to life, casting flickering shadows and sending thick, black smoke billowing into the sky. In the smoke, it felt like the countless souls trapped in these rotting shells were finally set free, rising in silent peace.

Zack stood for a moment, watching the fire, the reflection dancing off his visor, before turning to continue his fight against the apocalypse.

Before returning to his Mansion, Zack made a detour, stopping by an empty house to clean up. He carefully removed the MV-01 armor and dragged a water hose outside. As he sprayed the suit down, blood and grime washed off, pooling on the concrete. After giving it a thorough rinse, he put the armor back on and headed out toward Mansion No. 9.

In the eerily quiet neighborhood, only Zack’s heavy footsteps echoed through the empty streets. The once-constant groans and growls of zombies had fallen silent.

“Ego, how much power do we have left?” Zack asked, his voice reverberating inside the helmet.

“Sir, barring any unexpected issues, the local power grid should last about eight more days,” Ego replied.

“What about the surrounding areas?”

“Two days ago, widespread power outages began in neighboring cities. Currently, only a few regions worldwide still have power.”

Zack checked his armor’s battery. Over two hours had passed since he left the Mansion, and the armor was down to 3%, just as Ego had predicted.

“Looks like it’s time to prepare for life without power,” Zack muttered. With the MV-01 armor, he could now venture into more dangerous areas to scavenge for supplies. His mind drifted to the nearby industrial park—full of valuable resources like steel, alloys, and heavy machinery, all crucial for future upgrades.
