Beyond the Red Line
Beyond the Red Line (BTRL or BtRL) is a standalone total conversion based on the popular Re-Imagined Battlestar Galactica series. It features a seminewtonian flight model.
BTRL has released a playable demo of the game. It is designed mostly for the multiplayer though a short singleplayer campaign is included as well.
The demo is available for download from FreeSpaceMods.net, but there has been little sign of further development for over a year and the project is widely believed to be defunct.
