Just finished the scripted mission. Have to say, the mouse flight takes a bit of getting used to, especially only having a standard wheel mouse, I've lost the missile and "select nearest target" buttons on my 4-button-with-hat joystick.
That said it does work well enough, except it now feels like I'm playing a first person shooter, which I guess was the whole point of it all. I'd rather use a joystick anyday though, maybe in time, one of the clever WC folks, (HCl et al.) will figure out how to do it.
Couple of questions, I didn't look hard for it, but, where's the radar? And, looking at the 3rd screenshot on the CIC home page, it seems to indicate a multiplayer chat option, which I can't seem to see in this demo.
