NAME
FreeOrion - turn-based space empire and galactic conquest game
SYNOPSIS
freeorion [OPTIONS]
DESCRIPTION
FreeOrion is a turn-based space empire and galactic conquest (4X) computer game being
designed and built by the FreeOrion project. FreeOrion is inspired by the tradition of the
Master of Orion games, but is not a clone or remake of that series or any other game. The
game is about the construction of a living, breathing universe in a grand campaign model.
You can develop your own galactic empire and explore new star systems with your fleets as
one of several unique human or alien species. Colonization of new worlds, researching new
technology, managing your resources and defending your planets against the AI or other
human players on a galactic scale are your main objectives.
