Yes, there is a lot of developer diary blah blah blah going on in this video, but there is also a lot of raw, direct footage of Ancient Space's gameplay in action. And it looks pretty cool.
One weird thing I noticed is that so much of their footage makes the game look 2D. It's only when you look closer that you see you can in fact move your ships "up and down" as well as "left, right, forwards and backwards".
For a game that came out of nowhere it sure is out soon: September 23.
