We are happy to tell you that you can now help us test the latest public beta patch for Civil War II. Just be sure to understand that this patch, although seemingly quite stable, is still in the work. As 'RC4' indicates, it is the fourth iteration of the next patch-to-be, with 3 release candidates already tested and played by our fellows beta-testers.
Nothing horrible should happen if you try it, but again, this is not an officially released, quality-insurance tested, patch. Your feedback is more than welcome though. As for the definitive release date of the next official patch, we don't know. Probably not before summer, with all the bees busy on several game projects.
