I think about 90% of the work before an internal alpha is done.
Depending on what creeps up there, there is an unspecified amount before something more public, like a beta.
Problem is, that I have very little time to work on it right now (I'm basically all alone on this mod),
but I do want to get this playable, especially considering the amount of work already put into it.
But as for specific dates, or time tables - no such thing.
