I was absolutely certain that I had seen this symbol before, and after discussing it with my crew I now also know where: It was decorating giant columns in Mu. On the back of the rock, you can see some fine engravings of pictographic writing. A clue? Maybe there are other ways in, and this will provide the key. I wanted to question the guy I saw earlier, but he was nowhere to be found, and nobody on the Pyke seems to know who he was. Did I just imagine the conversation? But where did the rock come from? It seems there is only one way to find out. We have to go back. And this rock will help us do that! Congratulations! You have successfully completed Mission Deep Sea. But the search for Mu is not yet over. If you want to really put your teamwork as a crew to the test, you can play more missions. Start at a level of difficulty of 18 and raise it by one each time you complete a mission. You will no longer have to count your attempts, but keep track of whether you have used the distress signal token. Free task selection always applies. How far can you get?
