No offense, but you are gonna die
when other Inferno forumites see this topic...
It's just that this question has been asked a lot. So, here is the answer:
R2 is not done, and it is nowhere near being done. Woomeister has been working alone on it for a while now, you won't be seeing it for a long, long time. Also, R2 is now called "INF SCP". They have dropped the storyline, have created a new one, no one knows what the hell is gonna happen to the Gargant, and the Ancients have been cut out completely. Though I hear a sub-campaign called "Gateways" will feature them...
But, Inferno: Alliance, which is a prequel to Inferno, should be coming out soon. It's being tested now... correction, it is almost ready to be tested.
LGM is working on Steadfast, an Inferno-based campaign; and I am building Dreamcatcher
, a sequel to R1's storyline. Maybe these will hold you over until INF SCP is released.
