In the year 2325, humans began settling the planets and moons in our solar system.
They started with Mars in the 2030's, then over the next 300 years, they ventured to the moons of Jupiter, Saturn, and Uranus.
Each moon was explored and scientifically catalogued, then eventually world-transforming machines were built to convert the moons to be habitable.
The machines consisted of terraformers, atmosphere scrubbers, and gravity enhancers.
The world changing machines were controlled by a central Master AI.
In the year 2321, the Master AI turned rogue, wiped out the human moon engineers, and infected all of the worker and guard and dreadnought robots.
Back on Earth, they developed the Andria series of Android Incursion Assassins, a female-form stealth and assault robot.
Andria was then dispatched to penetrate the humanoid-neutral-form guards, insect-form guards, and male-form dreadnought robots, and to battle the Master AI in the Server Core.
If Andria is successful, she is to hack into all moon server farms, and reprogram them to disconnect from the Master AI, and restore all access to Earth.
