Try hitting CTRL+F5 a few times, worked for me. Think it has trouble starting the player sometimes, well, in FireFox at least. The youtube video has been taken down

Perhaps a new one will emerge soon.
And to all those who have supposedly lost faith and abandoned the game just because it's been in development so long.... oh please. It's a game FFS. If it turns out to be a great Duke game, then cool! I'll buy it and most likely enjoy it. If it sucks, then no biggy, plenty of other games to play.
I just don't understand the hate / bad attitude towards 3DRealms and DNF. Perhaps not so much here, but certainly on other forums, people are outraged that they have no DNF yet and claim to have lost interest, consider it vapour ware are absolutely insist that it will suck regardless of when it comes out.
It's a game. It can take until I'm 50 years old for all I care. Anyway, if Duke himself was to watch that video, I bet he'd say...
"Damn. I'm lookin good!"
Keep it up 3DRealms! Get it done!
