Halcyon Sun is a dogfighting game set in space that mixes gameplay sequences with the narrative of a science fiction TV series. It was originally released for free and exclusively downloadable through the website Freeloader.com as an episodic series of twelve instalments released every two weeks, of which the first one was launched on 3rd November 2000. Next to the main game, players could also read additional reports and briefings on the official website to extend the game. Through poor distribution however, later parts missed the release schedule, causing players to use hacks to retrieve the episodes from the website. It faded quickly into obscurity and the entire package was re-released as a single game on a CD-ROM.
