Project Hydra? There's little to no information about it. You could discuss 'what' it could be in CC, but really what else is there to discuss about it so far?
Didn't Hellgate London die? Their company fired everyone and got bought out and the people that bought them are sueing them for legal rights to their games, are they not? Something like that. I know they closed down the forums and everything, but didn't they close the forums too? Haven't even heard of the other two games.
