Nothing. Risen seemingly ended after the 3rd one, and now PB are busy with ELEX 2, as others have pointed out.Sorry for the bump.
What has changes since 2013? To Gothic and Risen I mean. I've been searching for the info on forums and the bulk of the threads are not accessible anymore. What is happening guys?
However, THQ Nordic now own the other franchises too, so in theory we could see new development there.
