Secrets

So there are quite a few known secrets about expedition 33 such as the hidden rooms in the manor. I’m just curious if there are still any other secrets that People just haven’t found yet. I looked and there was a post from about 6 months ago that had the game devs confirming there were still more secrets. Also one thing that bothered me greatly is that there are two endings but it would have been masterful if there had been a third ending that you could only get if the final fight ended in a “DRAW”!!!
