A Deadly Virus Turned the City Into Red-Eyed Monsters, Forcing Survivors to Hide in Bunkers

A deadly virus swept through the city, turning ordinary people into red-eyed monsters. Survivors had no choice but to hide deep inside bunkers, cut off from the outside world. For months, a family struggled to endure hunger, fear, and the endless sounds of creatures above. But soon they realized the military was not there to rescue anyone… they were sent to wipe out the infected.
What began as a fight to outlast the virus quickly turned into a nightmare of survival, as the family discovered the infection was already within them. The monsters they feared outside were not the only danger — the real horror was what they themselves were becoming.
