About the game
In the near future, during their first interstellar travels, humans encounter a great evil that has been roaming the galaxy for the last few eons. This evil being is an incarnation of the last ancient immortals called Notorious Mental. Mental has set forth to wipe out the Human Race, just for fun, as it has with all the other civilizations in galactic history.
