One day, an unknown disease struck people, turning them into monsters. But this disease did not affect everyone. Those who had immunity hid in the Arks - fortress cities.

You are a soldier whose task is to protect the Ark. Every day, your squad searches for monster nests to mercilessly exterminate. These monsters hate people. Although they have changed in appearance, their development is not inferior to that of humans, which makes them truly dangerous.

Since childhood, you have been taught that the world has been struck by filth. But... What if reality is not as you know it?
