There was a different era 200 years from now. Humanity has experienced many technological revolutions. Thanks to these technological revolutions, people began to spread into space. They established colonies on Mars and the Moon.

The biggest helpers of humans in this process were robots with advanced artificial intelligence. Robots could work even in difficult environmental conditions.

Humanity also found peace within itself. No country has been at war with each other for the last 100 years. Humanity was literally living a utopia.

But this utopia was not so good for some.

People became aware of this fact with a surprise attack on the moon colony. Humanity must discover who this unknown enemy is and why he is attacking.

People will fight a great war to avoid losing their most important castle outside the world...
