Titan Suit

As the dense swarm of bone spurs streaked toward him, Zack activated his auxiliary thrusters, pulling into a sharp, evasive maneuver. Still, curiosity got the better of him. Deliberately, he let one spike strike the alloy on his left shoulder.

Bang! The bone spur shattered on impact, leaving not so much as a scratch. "That's it?" Zack sneered, unimpressed. Without hesitation, he launched eight spiral anti-ground missiles, each targeting clusters of the Spitter below.

Boom! Boom! Boom!

A series of fiery explosions tore through the horde, leaving a long, blazing trail of destruction. More than half of the Earth Roars were obliterated in seconds. "Sir, there's a Mutated Lord at your three o'clock," Ego's voice cut in.

At the same time, Ava's second-generation Avalon swooped down, locking onto the Mutated Lord with its depleted uranium-loaded cannon. The Avalon's 20mm cannon roared as Ava strafed the horde. The Silverback, despite its formidable defenses, was riddled with holes and collapsed, bringing a line of lesser zombies down with it. "Be careful! These zombies have ranged attacks now," Zack warned over the comms.

"Understood," Ava replied without hesitation, pulling the nose of her plane up and away from the bone spurs. As a soldier, following orders was second nature to her.

"Sir, high-frequency sound waves detected. Suspected leader. Coordinates uploaded," Ego reported.

"So soon?" Zack was genuinely surprised. His original plan had been to use the nuclear strikes to divide the massive zombie tide into smaller groups, then locate the leader hidden among them. The odds of finding it so quickly were slim.

"Good luck," Zack muttered, a smirk forming as he adjusted course toward the marked location. As he approached the marked zone, the density of mutated zombies increased dramatically. Dozens of Mutated Lord, countless lords, Hunters, and even more Spitter packed the area. But what truly made the leader hard to find was its uncanny ability to blend in with ordinary zombies.

Ordinary in appearance, indistinguishable in movement, and emitting sound waves inaudible to human ears, the leader was an enigma that even the end of the world hadn't fully revealed. Zack and the Vanguard Organization were among the few who knew of its existence. "But luck isn't on my side today," Zack muttered coldly, eyeing the horde. Despite the nuclear strikes, which had annihilated tens of millions of zombies, the leader had survived, hidden among its monstrous army.

"Sir, high-energy reaction detected!" Ego's sudden warning snapped Zack's attention forward.

A dark shadow burst from the horde at an incredible speed, heading straight for him. "What the hell?" Zack exclaimed, instinctively yanking the controls. The Apex suitresponded with an almost impossible sharp-angle turn, narrowly avoiding the incoming projectile.

Boom! The shadow missed Zack, arcing through the air before slamming into the ground like a cannonball. The impact left a massive crater, the force shaking the surrounding area. There were no flying zombies, which meant this creature had leaped over a hundred meters into the air purely on raw power. "A Sarcoma?" Zack muttered, turning to get a better look at the monstrosity.

The creature below him was unmistakably a Sarcoma , but far more formidable than the one he had faced before. Last time, the Sarcoma had been little more than a newborn, barely understanding its capabilities. This one, however, had fully matured. "Roar…" From within the deep pit, the Sarcoma raised its head and locked eyes with Zack. For a moment, Zack could have sworn he saw something disturbingly human in its gaze—a mocking, taunting glint.

"Sir! High-frequency sound waves detected!" Ego's voice broke through Zack's thoughts. "The source isn't the leader—it's the Sarcoma below!"

Zack frowned. "You're telling me the zombies are learning to lie now?"

"Target locked!" Ava's voice cut through the comms as she dove toward the Sarcoma in her Avalon. The depleted uranium rounds from her 20mm cannon streaked toward the creature in a fiery torrent.

"Roar!!!" The Sarcoma roared as the bullets slammed into its body, creating fist-sized craters in its thick flesh. But even depleted uranium rounds, powerful enough to shred through tank armor, couldn't pierce its defenses.

With a deafening crash, the Sarcoma leaped again, the ground beneath its feet exploding into rubble as it soared over a hundred meters into the air. It reached for the Avalon, holding its own against the relentless cannonfire. But Ava had been warned. She quickly pulled the nose of her aircraft upward, maintaining an altitude of two to three hundred meters to stay out of the Sarcoma's reach. "Sir, the depleted uranium rounds are ineffective. I'm withdrawing to attack other targets!" Ava announced before diverting her attention to the masses of zombies below.

Moments later, the Aegis and the unmanned armors arrived. "Master, I can break through its defense. Let me handle it," Lillian offered from inside the Aegis. Her abilities were uniquely suited to taking down heavily armored foes.

"No need. You and Ava will focus on the second sound signal. Leave this one to me," Zack ordered, his tone decisive.

"Yes, sir!" Lillian replied without hesitation. As the Aegis and the unmanned armors veered toward another section of the divided horde, Lillian and the seven Fearless Warriors leapt from the aircraft, falling a hundred meters into the swarm of zombies below.

They landed with an earth-shaking crash, their impact seemingly swallowed by the endless tide of corpses. "The sound wave's origin has been pinpointed! Kill!"

What looked like drops of water falling into an ocean suddenly erupted into chaos as Lillian and the Fearless Warriors carved their way through the horde like a blade through flesh. Meanwhile, Zack hovered mid-air, watching the Sarcoma below. "Call the Titan," Zack commanded coldly.

The Aegis's sleek form split into many modules, each equipped with thrusters of its own. The modules shot through the air like homing missiles, converging on Zack. The Apex armor began shutting down its systems as the Titan modules attached themselves to it, piece by piece. With each module added, the suit grew bulkier, heavier, and deadlier. The thrusters maintaining Zack's hover cut off, and he began to plummet toward the ground, a mass of several tons. The sound of machinery locking into place echoed in the air as each piece of the Titan suit connected seamlessly. To Zack, the sound was like a symphony—a heavy, mechanical rhythm no warrior could resist.

"Roar!!!" The Sarcoma, seeing its chance, let out a furious roar and charged toward Zack's falling form with terrifying speed. Its massive frame, over four meters tall, moved like a blur as it barreled through lesser zombies, knocking them aside like ragdolls.

As Zack neared the ground, the Sarcoma leaped once more, channeling its full momentum into a single devastating punch aimed directly at him.

BOOM! At the same moment, the final piece of Zack's armor—a massive, reinforced head module—locked into place, completing the Titan suit. Zack slammed into the ground like a meteor, creating a crater several meters deep. "The neural link is online. Full system functionality achieved," Ego reported.
