In the future, XEN units are used in combat and to explore places where humans have never been before. They are clones of genetically improved girls, and they have the unique ability to synchronize and control powerful robots.

Recently, Earth has lost communication with one of its colonies - a planet called X-69, inhabited exclusively by XEN units. Therefore, they decide to send a young commander to check what’s going on.

XEN units use Crystals to improve their equipment and evolve, so when the X-69 colony discovered a new mineral, they decided to use it. Little did they know that its power would end up corrupting them.

Your mission is to discover what happened in the planet X-69, fix the issue and re-establish communication with Earth. In order to do this, you will have to venture into the planet, defeat the corrupted XEN units and destroy the source of energy that caused the problem.
