The world changed in a single moment.
A scream.
A bite.
And the merciless death of someone irreplaceable.

What began as an ordinary workday spiraled into a nightmare drenched in blood and betrayal—where trusted friends turned into ravenous monsters, and the living were devoured without mercy. Paralyzed by grief, hopelessness took root. But even in despair, a message broke through the darkness—a message from long-estranged family, igniting a spark in a heart that had nearly given up.

Regret. Guilt. A desperate yearning for reconciliation.
There was now something to live for.
Something to protect.
A reason to fight.

But just as hope flickered, a grotesque abomination emerged—an unnatural creature reeking of rot and death, far worse than any zombie seen before. With death closing in, salvation arrived in the form of a being not of this world—an angelic figure offering a second chance and a mysterious system unlike any other: one that grants power, but demands everything.

Three paths appeared—each one a weapon in the war to come.
An infinite arsenal.
A fortress of might.
The fury of close-range combat.

With every level gained, the world itself evolves.
Allies rise.
Monsters mutate.
And the mystery behind the outbreak—and the system's true origin—grows ever darker.

This isn’t just a fight for survival.
It’s a reckoning.
Because power always comes at a price.
And in a world devoured by the undead…

The price may be everything.
