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

Alyssa's hands trembled as she unrolled the classified site maps across the strategy table. 


….Her last act before fleeing Dyford had been copying these incriminating documents showing locations of all the corporation’s clandestine viral research hubs dotted menacingly across several continents. 


Now to expose the menacing constellation to the right heroic eyes. 


Jiro and Ruka leaned in intently, faces taut. 


….Alyssa took a deep breath, drawing on wellsprings of courage she hardly recognized in this defiant woman who had emerged from the chrysalis of complicity. 


"Six core facilities are housing the most dangerous bioweapon programs by my estimates," 


….she began, orienting them to the Molecular Research Centre where she had worked. 


"But over twenty affiliate sites globally also handle development, testing, and..." 


 - she swallowed hard - "...human trials."
