It compiles fine. All the code is there (except the Artillery thing, looks like).
My guess why nobody is doing anything with it would be the restrictive license.
It's better than leaked source code, but still, would I be doing something with it, I wouldn't brag about it.
Especially since IP has been recently resurrected by an active company.
Thanks to the uploader just the same. I understand the limited possibilities of releasing the source for a commercial game with multiple publishers and all that.
