My best theory right now is that this is some kind of emergency exodus thing, conducted in secret so that life would survive in the event that the Reapers won. The press release says that it takes place a long time after the original trilogy, which makes sense. Whatever intergalactic travel they came up with, it would have taken a long time to get to Andromeda. Protagonist is not in the trailer, it seems, but it'll be a human (gender chosen by player, of course). The biggest question I have right now is what kind of FTL system is that? They went between systems in *seconds*. Also, there's a mysterious ancient race and ruins and other plot stuff and the goddamn Mako! So excited!
