About this game

Humanity didn’t just fall. It mutated.

A catastrophic biological outbreak has turned the world into a hostile wasteland. The infected roam forests and abandoned facilities, driven by something more than hunger.

But the undead are not the only threat.

The virus left a lasting mark on the survivors — subtle at first, then impossible to ignore. Exposure affects the body and mind in unexpected ways. Managing contamination becomes just as important as managing hunger or ammunition.

In this mature survival RPG, every choice has consequences.

Resources are limited. Nights are dangerous. Trust is fragile.

Survival isn’t just about staying alive — it’s about staying human.

 Core Survival Experience

• Explore dangerous environments

• Gather materials and craft equipment

• Build and upgrade your base

• Defend against waves of infected

• Manage hunger, stamina, health, and contamination

• Survive dynamic day/night cycles

The world is relentless. If you are not prepared when darkness falls, you won’t last long.

  Infection & Evolution System

The outbreak introduced complex biological effects.

Exposure to the virus may lead to physical changes that influence gameplay, character interactions, and long-term survival strategies.

Some changes may provide advantages. Others may complicate your journey.

The infection is not just a mechanic — it’s part of the world’s evolution.

Attention! For adults only!
