Hey!
I don't remember who was the user who first mentioned this game here on the forum, but anyway, I just wanted to say that the registration for the closed alpha is open.
There are some videos of this game (made using Unity 3D engine, but it looks amazing) on YouTube if you want to see how it is. You just have to search for 'elite squad game'..
