freeorion binary package in Ubuntu Bionic arm64

 FreeOrion is a turn-based space empire and galactic conquest (4X) 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.
