Originally, CCP presented Kali to the world as an epic expansion that would fundamentally alter the universe. It was huge. New models, textures, Windows Vista support, a completely new factional warfare system and much more. The revolution was underway, but soon they realized that it just was not possible - or sane - to pull off that much content in one giant bundle. So, they split it into three and Revelations I was born. On November 28th, the first of three parts hits the live servers.
Currently available on their public test server, Revelations I not only continues the theme of Biblically named expansion packs, but also further fills out a game world that has been relentlessly growing since the title's initial launch in May of 2003. Unlike many expansions we see, Revelations does not just throw a couple new classes and races (or should I say skills and ships) into the equation, but systems that fundamentally alter the experience (although there are four new battlecruisers and four new battleships to go along with those systems).
