Three years after the victory on a dying Earth.

In 2024, humanity won the fight against the unknown invaders known as the Primers, a battle that lasted two years. The Primers have departed, and peace has returned to Earth. However, the population has been reduced to 10%. Civilization is on the brink of collapse. Those who survived continue their efforts to recover.

Three years have passed, and it is now 2027. Humanity faces another problem. The Primers left many aliens (colonists) behind on Earth. They formed a group and occupied the cities to survive and settle on the planet.

Humans and aliens are constantly fighting against each other. Through this ongoing conflict, both ethnicities have grown weary of one another.

And the remaining threats.

There is an even greater problem. The invaders continue to breed on Earth.

The invaders are forming an underground nest, the ruins of which are growing larger. Their numbers have already overwhelmed humanity. Humanity must continue to fight to prevent the invaders from dominating the Earth.

The rebuilding of society and the revival of civilization are progressing slowly, and each day is a struggle to make that day a reality. Humanity continues to fight against the remaining threats.
