It's done when it's done, so it's done now!
What else can I add? You may now download the first Open Beta to Red Alert 3: Trinity Defense. Please read carefully, if it is the readme or certain in-game tooltips - especially if you have the impression that something refuses to work.
As a sidenote, I don't have all art assets finished right now. There's still a lot of work to do and you'll probably notice that immediately. For now, I'm glad that the gameplay works well so far - this was hard enough! However, if you encounter any bugs which are not represented on the known issues list, let me know.
Now, go re-install RA3 if not yet done for RA3: Upheaval or whatever and enjoy R3D.
