Twigs added and changed some stuff on the website, and will do so over the next few weeks. I highly recommend you all check it out every now and then.
By the way, there is a new campaign that's in the works. You can find a couple teasers of it on the Rebel Defiance Website. It seems like it will be much better than the previous ones, and it appears that it will have a Risk-like metagame, like what Global Conflict does with BF3. These are just my thoughts however, so visit the site and see for yourself!
