Its only a beta but its pretty rough so far. Not many scenarios or platforms available and those that are aren't for the most part fully fleshed out. Should be a good game but needs some more work. The interface etc is very good.
Theres almost no British kit so far, what there is is a bit misinformed (Type 82s anyone?). In short needs a bigger, better, database and some UK centric scenarios.
I'm quite tempted to make some myself.
It isn't a huge download (130 megs) so worth having a pop at.
