When Dr. Isaac Gilmore tweaks the genetic code of a captured alien virus in 2041, he accidentally creates an unspeakably destructive shapeshifting plague—dubbed the Xeno-5 Strand. What begins as an isolated lab outbreak in a futuristic Tokyo research institute soon erupts into a full-scale global disaster.

Just years after the world beat back the original Xeno-3 epidemic, this new mutant “protean” strain proves even deadlier, triggering chilling bodily transformations. In hours, the entire metro area becomes engulfed by a biological tidal wave turning millions into ravenous beasts acting as one.

With apocalyptic annihilation looming, special operative Jiro Yamada ventures into the hotzone’s shifting landscape of alien tissue, nightmarish architecture and strange psychic phenomena to rescue Dr. Gilmore and secure research needed to formulate a cure. However, shadowy political interests have other plans for deploying the lab-grown viral payload that Jiro is determined to stop at all costs.

He bands together with the doctor’s gifted young daughter and a squad of misfit scavengers caught behind enemy lines. But can their makeshift alliance adapt fast enough to withstand the nightmare bubbling up from secret military Crypt labs seeded across the city? Hope hangs in the balance on whether Jiro’s team can uncover a counteragent before a key zero hour when Protean will enter an unstoppable final stage.

Protean Relapse 2041

The inky blackness of night blanketed the forest. 


….The trees stood like silent sentinels. But the calm would not last. 


Jiro slid forward, his skilled eyes probing every shadow and shape. 


..He moved with the stance of a seasoned hunter stalking his prey. 


..Ruka followed directly behind, her footsteps making no noise on the soft loam. 


 In her sure hands, a pair of wicked daggers caught faint glints of moonlight peeking through the canopy. 


They were warriors - and the hunt was on. 


Up ahead, the first dim lights of the supply camp flickered into view like will-o-wisps in the distance. 


Jiro paused, motioning for Ruka and the others to freeze. His sharp gaze swept over the makeshift buildings and parked truck transports. 


..Two guard soldiers patrolled with a lazy gait, their weapons held casually - they did not anticipate any trouble this quiet night. 


Jiro's fingers flashed a series of hand signals, relaying his tactical instructions.
