Train to Busan emerges

The Nightmare World trembled as another domain merged into its chaotic expanse. The Train to Busan domain, teeming with its own unique breed of fast-moving and highly aggressive zombies, had arrived. Jason X, in his wisdom, decided to place this new domain under the jurisdiction of Mr. X, given his experience with managing undead hordes.

As the Train to Busan zombies integrated into the Nightmare World, they began to merge with the other zombie types already present. The zombies from the Evil Dead, Dead Rising, Dawn of the Dead, The Walking Dead, World War Z, Night of the Living Dead, Dead Island, Left4Dead, House of the Dead, and Resident Evil (including those infected by the T-Virus, G-Virus, C-Virus, T-Veronica Virus, Mold, and Las Plagas) began to mingle with these newcomers.

The swift and relentless nature of the Train to Busan zombies brought a new level of chaos to the already tumultuous world. Their speed and aggression were unmatched, making them a formidable addition to the existing hordes.

Meanwhile, other infected types like the Cordyceps from The Last of Us and the Necromorphs from Dead Space sensed the presence of the Train to Busan zombies. This sensing stirred a new wave of tension and adaptation among the various infected entities. The Cordyceps, with their unique fungal infection, and the Necromorphs, with their gruesome transformations, found themselves interacting with the new breed of zombies, creating an ever-evolving landscape of horror.

The presence of these new zombies also drew the attention of other powerful entities within the Nightmare World. Count Dracula and Viktor, always seeking to assert their dominance, watched with interest as the dynamics of the undead shifted. The AI factions of Skynet and the Matrix continued their occasional conflicts, undeterred by the influx of new zombies.

Blair Witch, having submitted to Jason X's rule, observed the merging of the zombie hordes with eerie silence. The Wendigo, already finding kinship with the undead from the Pet Sematary domain, felt an increased hunger as the numbers of the undead swelled.

Despite the growing chaos, Jason X maintained a firm grip on his kingdom. The Enforcers, led by Jason X, continued to patrol the various domains, ensuring order was maintained amidst the constant upheaval. The Nightmare World, now a sprawling and ever-expanding universe of terror, continued to thrive under Jason X's reign, ever prepared for the next domain that would merge into its terrifying fold.
