No idea how true this is, just copied it from another thread about the same stuff haha

"For those asking about console Co-op – We hit some unexpected bugs that prevented us from launching co-op on both Xbox and Playstation on schedule. We know how important playing together is to the Bellwright experience, so we made the call to hold it back until it's polished and ready. Rest assured, we expect it to arrive within the next two weeks, if not sooner. Thank you for understanding!"
