The Hellgate: London Website has a post with a general outline of what is described as the "TONS of new content for subscribers" to Flagship's coming action/RPG, saying paying subscribers will get access to additional weapons, monsters, and even character classes, among other things. This additional subscriber content is one of the topics in the Q&A with Bill Roper on Shacknews, and article-format conversation about premium content, as well as changes being made to the game based on feedback from the beta.
