Aye, it was a treat to find. I have a soft spot for the Vipers (especially the Mark III from Blood and Chrome) so any game or mod that features them heavily gets my attention. With so few official BSG games out there (and all of them being abandonware barring Deadlock) it's largely down to fan creations to carry the franchise. I didn't expect the controls to work at all flatscreen, but they're somewhat manageable already, which is what inspired me to pitch their update for flatscreen users.
Agree with you about multiplayer wholeheartedly; it would probably be a hassle to produce and would likely be touch-and-go in practice. I was moreso referring to a simple combat mode with a bunch of Vipers and Raiders for some cinematic challenge, sort of like Star Wars Battlefront's Instant Action modes. Regardless though I'm amazed enough already that indie games like this and the similar title Colonial One can tackle the Vipers' three-dimensional movement to this degree.
