Firefly Online is a strategic online role playing game (RPG) based on Firefly, Joss Whedon’s cult-hit television series. Get ready to take to the skies in the delightful western / science fiction universe of Firefly, visiting the locations and meeting the people made famous in the TV program. The core of the game is to fly your ship from place to place, taking odd jobs and focusing on keeping your ship flying. Beware; the 'verse is a dangerous place! Hazards from overzealous Alliance inspectors to ravening reavers await the unwary.

Note: Firefly Online's Facebook page has not been updated since 2016, and the website is down. The game appears to have been abandoned.
