Its still having episodes released, technically speaking its v1.0 came out quite a while ago now. Given the narrative in their episodes I would suspect that 2 will follow directly on storywise from the end of 1's episodes.Isn't the first game still in early access?

Co-op would be good, there used to be (dont know how well it was kept up to date) a co-op mod for Long Dark 1 , I tried it a while back with that mod and it was pretty good , although tough, in co-op.Looks good, I never finished the story of the 1st one, but was hooked on the base survival game for a couple of weeks a few years ago
Looks like it could be co-op?
