Unchained: A Tabletop Roleplaying Game

From the introduction:

The last thing you remember was being onboard a great ship, being transported to who knows where. Now you are suddenly awakened by the sharp pinch of a tiny crab. You instinctively grab it and fling it away. You find yourself soaking wet, on the edge of a sand covered beach. You examine yourself and find that you are no longer bound. You have nothing, but your wet tattered clothing. You look around and see no one. No one shouting orders. No one to answer to. You quickly realize that from this moment forward, you are in full control of your own life. You are now free.
