Customization, create a class, firing range and a real match coming shortly. Request what you want to see, since it's not officially released yet and I don't know what information is out there and what isn't. The game looks better than the videos. HD PVR gaming thing only caps 30FPS, and youtube eats away from quality as well so that's the best you'll end up with.
