The ProSonic Anniversary Pack is here! It includes a couple goodies (including the ProSonic engine itself), although none which I will provide any actual support for. I don't consider this an "official" release. I have called this a "camera demo" because there's no player activity yet. I did what I could in the short amount of time I offered myself, so I hope some people are happy.
You can click here to download the anniversary pack. A Pentium II processor is the bare-minimum requirement, but I strongly recommend a Pentium 4 processor as it will do a far better job with performance.
