Yes: Natural Selection 2 Beta Game Footage
Ooh, we've got the first official game footage trailer from the Natural Selection 2 beta! The hybrid RTS-FPS multiplayer sequel is in pre-order-based beta at the moment, where it is being tweaked and honed and squeezed into shape by the testers and developers alike. For those of us who haven't dared dip in, however, it's not been clear quite how this thing plays. Unknown Worlds have addressed that with a brand-spanking new video, which you can check out below. It shows the RTS mode, as well as lashings of combat. There's also perspectives from both alien and marine side, giving you an idea of how the game should play out.
And it looks good.
