Oh Finally the download link is here. Thanks! 
Edit: I got error when launching the demo:confused: :
And I got Swarm Agent icon on my toolbar. What is it?
And when switching to viewport mode then hitting play I getting red message : “Lighting needs to be rebuilt:1 object needs to be rebuilr” and when I rebuild lights (which takes almost an hour and eats all my ressources) I still get the same red message about ligthing needing to be rebuilt. And the demo runs very porrly for me eventhough i could run all other demos fine at Epic quality.
