It is the year 2086. Earth has finally joined the Galactic Union; people, knowledge, and technology can now freely travel to and from Earth. New technology is solving many of humanity's problems, such as disease and food shortage, and galactic tourism is quickly becoming a boon for Earth's economy. However, not all changes are positive: with its borders open, Earth is no longer considered a protected location by the Galactic Union, and not everyone who might come to the planet is there just to see the sights. The Galaxy Police are dedicated to fighting interplanetary crime, and while they may provide the tools, Earth itself must provide the talent, and those recruits are going to need some training to keep the peace.
