The Marine Contra leaps from a drawbridge across a vast canyon in a burst of speed and chakra. Thousands of Red Zetsus tumble into the chasm while hundreds keep pace and climb the drawbridge's bracing system. He electrifies his hand with Lightning Release before grabbing one of the bridge girders. Electricity surges within the metal, dropping dozens of flesh-eating ghouls like flies in a bug zapper. He sprints through the ruins of Fort Firestorm, avoiding the zombified soldiers lumbering around.
Jim rushes past the abandoned APCs (Armored Personnel Carriers) and tanks obstructing the roads. The bodies stuck on the stalagmites roar and twitch; the Red Zetsus trapped within the armored vehicles grab at him from the windows as he dashes into the flooded outpost. Uneasiness washes over him as the terrain becomes tedious to traverse.
Blood conceals the potential hazards beneath the crimson water. Silhouettes of all shapes and sizes appear in the shallow regions; he jumps atop a boulder, preventing the cannibalistic fiends from pulling him underwater. Debris inhibits the abominations from emerging; nevertheless, a decaying corpse breaks free. It leaps from the water as he pulls a small metal rod from his inventory.
The metal rod extends, impaling the Red Zetsu's fleshy ribcage. The abomination screeches and claws at the mass murderer holding it in place. He grabs the bo staff with both hands, sending several volts inside the flesh-eating ghoul's body. Jim shakes the metal staff until the rabid mutant resembles a screeching, smoldering red blur moving up and down at a blistering rate. He increases the wattage, setting the abomination ablaze; its residual skin and muscle tissue rip and tear, then fall apart from the legs upward. The Red Zetsu's burning bones and internal organs splash, then fizzle in the bloody water until all but its head remains. The war criminal flings the flaming skull upward before batting it away into the canyon.
The abominations arise from the crimson water; he is beyond their reach but surrounded. Jim deflects the Red Zetsus, lunging at him, and jabs down at them as they climb and sway the boulder. He maintains his balance, walking as the bolder rolls; bones crunch and grind against the concrete along its path.
The fugitive's momentum progresses to a brisk walk, flattening the walking corpses underneath akin to a gory toothpaste squeezer as they vomit their rotting entrails. The sudden increase in pressure expels the built-up gas and bodily fluids within the Red Zetsus in crude flatulence-like emissions. He almost loses balance due to his twisted sense of humor.
The boulder's velocity hastens. Jim accelerates from brisk walking to light jogging, swatting the lunging mutants away with his bo staff in a nonstop two-hand underarm spin. Dead ahead, the runaway boulder is on a collision course with a reinforced wall. He shoves his staff down a Red Zetsu's gullet, poll-vaulting over the blockade. The boulder impacts the rampart, squishing another abomination.
He lands a three-point pose, holding his bo staff behind him. He stands, gives the weapon a quick spin before it retracts, and seals it in his inventory. The ground is vibrating—a constant pulse strengthening every second. The low rumble becomes a violent pounding, which he identifies as giant footsteps rushing toward him. He dodges the behemoth, trying to devour him whole. The mutant berserker crashes into the blockade as he crouches on the vertical surface, staring in disbelief at the hulking monstrosity.
"Sweet mother-Marry of Josephine!?! What the goddamned titty-fuck is that thing!? Jesus Christ!!"
The bipedal behemoth's upper torso comprises multiple human and animal corpses partway absorbed into its flesh. Blood leaks from the grotesque abomination's eyes as it emits a constant jabbering/gurgling from its mouth. Its head resembles a hideous amalgamation of body parts (both animal and human), with two long fleshy tongue-tentacles coming out of what appears to be its mouth. He evades the inbound appendages, trying to impale him.
The berserker takes off after Jim, smashing and knocking around the blockades and military hardware. He keeps his distance, ascertaining the quickest way to immobilize the beast while assessing its weaknesses. He turns around mid-step; his hands fly through a sequence of seals. An upheaval in the ground trips the berserker; he backflips over a stalagmite exploding from underneath the road that impales the behemoth's forehead.
The Contra sustains his counterattack until the beast's tongue ensnares his ankle, yanking him in the air. He straightens his hand, severs the appendage using "Lightning Release: Synergistic Sabre!" and dodges another tentacle-like extremity. A horde of Red Zetsus amass atop the fortifications, spilling into the base.
"I don't have time for this!" Jim draws his rifle, dashing for the administrative towers. The mutant berserker pulls its head from the stalagmite and storms after him. He channels his chakra and runs up the skyscraper. He empties the stripper clip, firing at the berserker's joints to immobilize or slow it down. The berserker flinches a few times before a round maims its leg. The behemoth changes course without delay; with its massive arms, it grabs handfuls of the Red Zetsus, climbing the walls before cannibalizing them. The enormous biomass the beast ingests regenerates its injuries while mutating the behemoth.
A dense skeletal shell forms around the berserker's torso, arms, and legs; horns grow on its head, giving the beast a subsidiary demonic appearance as its inhuman extremities morph into razor-sharp claws and talons.
"You've got to be kidding me!" the mass murderer shouts. Despite the berserker's massive size, it scales the skyscraper after him at breakneck speed. The armored behemoth slams its powerful arms down at Jim. He uses substitution jutsu with the stalagmite; the berserker impales its hands. The explosive tags on the stalagmite detonate, catapulting the beast from the tall structure. The war criminal replaces his rifle's stripper clip while distancing himself from the hulking monstrosity. He dashes through the thickening horde using his rifle stock as a weapon when necessary; however, some of the mutants rebound as fast as he drops them.
Jim shoulders the rifle, resorting to Earth Release to redirect or obstruct the abominations in his path. He throws a half-eaten carcass off an anti-tank gun, then readies the twin turrets. The berserker explodes from the burning rubble, storming after the fugitive; a projectile impacts the behemoth's shoulder. The beast stumbles as its arm jerks back; he fires the second turret, stopping the berserker dead in its tracks. A mass of explosions envelops the armored behemoth.
"Eat my greasy shit, motherfucker!!" a semi-auto barrage of chakra-conducting shells hammers the hulking monstrosity within the smoke. Jim ceases fire, then crushes the half-eaten carcass's skull with his boot before it can bite his leg. He kicks the twitching Red Zetsu away; the berserker lunges from the black haze, then destroys one of the turrets, forcing him to dodge.
The beast's skeletal armor is now nothing more than tatters of cartilage and bone fragments. He draws his rifle, hoping the unarmored behemoth is vulnerable. It grabs at him; he runs up the berserker's arm, chambers a bullet, and fires, taking a chunk off its head. The beast swings its other arm; he b-twists, reloads, and fires—the round ricochets in the behemoth's skull, causing it to lose equilibrium.
The Contra lands, shoulders the rifle, and draws a kunai. The berserker grabs at him yet again. He ducks, spins, drives the blade into its exposed ribs, and shoves it further with his palm. Jim's index and pinky fingers extend as he holds the rest down with his thumb.
"Lightning Release: Synergistic Sabre!" the kunai conducts into a lightning beam, piercing the mutant berserker's abdomen. He tears out the electric saber, spilling the behemoth's intestines. The berserker swings its arm; the mass murderer tosses the galvanic blade overhead before flipping above the incoming appendage. The kunai's handle clings to his boot; the saber slices the berserker's jaw below its eyes in an unsuccessful decapitation.
He lands, then backhand springs away as the behemoth tries squishing him. The beast's tongue whips through the air. He electrifies his hand with Lightning Release; Jim catches the extremity centimeters from his face. Electricity surges within the behemoth's body, bringing the abomination to its knees; it tries ripping off its tongue, but he lassos the appendage around the beast's head and hands. The war criminal darts behind the berserker, then kicks its spine, breaking it in half. He channels chakra to his hand; concentric Rings of Power levitate above Jim's palm.
"Toot that ass up!" he twitches his fingers, propelling the Surging Centrifuge Jutsu toward the anti-tank gun. The berserker's eyes bulge as the barrel rockets straight past its meaty mutant mounds, bunker-busting the old backway boulevard without lube. He fastens conductive wire strings to the berserker's arms and around the trigger and locking mechanism. "I'm about to blow my load all over your insides…"
The mutant berserker stares at him, uttering a noise approximating, "What—the!?"
"Pause!" The fugitive fires the anti-tank gun, splattering the upper half of the behemoth's skull. The recoil pulls the barrel out; the chakra rings thrust it in. The wire strings binding the berserker's arms pull the trigger; the weapon discharges, destroying what remains of the beast's head. The anti-tank gun continues firing and resetting each round like an improvised bump stock configuration.
Jim is again sprinting for his life, unable to observe the spectacle. A sizable horde stampedes after him as he scrambles toward an armored personnel carrier. The Contra throws open the door, diving into the vehicle; an emaciated hand squeezes his ankle. He kicks the Red Zetsu away, then slams the door. The hordes of flesh-eating ghouls surround the APC, shaking and pounding on the armored vehicle.
Jim removes the cover below the vehicle's steering column, then connects the ignition and battery wires, energizing the radio. A Red Zetsu breaches the reinforced windshield with its arm, forcing him to duck. Jim jams a kunai in the ignition, then hotwires the APC; he revs the engine, shifts into first gear, and drops the handbrake. The mass murderer dumps the clutch with the revs near red, flooring the accelerator.
The tires screech as the vehicle rams into the horde. The cannibalistic fiend flails its arm, trying to grab him; he keeps his distance while shifting through the gears. The APC accelerates; visibility is scarce, but he steers toward the central tower's general direction. The abomination grabs the steering wheel; Jim loses control of the vehicle. The APC rolls—he clings to the seat with his chakra, safeguarding himself from injury.
The vehicle lodges into the tower's reinforced window upside down; he crawls from the wreckage with minor cuts, bruising, and slight dizziness, then shuffles into the building, leaning against a column for support. The war criminal uses a nearby switch to close the security gates before the mutants rush the barricaded entryway.
Now able to stand without support, he steadies himself while observing his surroundings. The moons illuminate the anteroom in a red hue. White noise emanates from an idiot box on a shelf between two desks; decrepit propaganda posters line the walls. Broken glass litters the floor; a sizeable steel fan spins above but does little to alleviate the smell of iron on the bloody tiles.
Besides the Red Zetsus pounding on the barricades, the reception area is somewhat calm; regardless, the mutant responsible for flipping an armored personnel carrier draws near. He stalks the lobby, approaching a dark hall. Past the reception desk, the Red Zetsu's footsteps squelch on the floor. Jim leans against a wall, halting a few steps from a junction.
