The Beyond the Red Line demo is a stand-alone conversion of Freespace 2. A test run; an experimental release; you know, just a demo.
Is this all free and stuff?
Yes, and it’s a two-part ordeal. Once upon a time, the Beyond the Red Line development team had a demo phase that established many things. Those established things evolved, and resulted in a focus to obtain what was once thwarted: a full game. The full Beyond the Red Line game is a separate entity in that it is being made by discriminating fans… for the discriminating fan.
