I tried playing AC 3 and got to the part where I'm freeing the hostages for the first time.
What happens is I get outside of the fort wall. As soon as I sneak onto the boat and try to free the hostage near the edge of the ship, I get caught. If I assassinate the guard first, I get caught still in plain site.
Is there more than one option?
I can free the other two, the ones within the fort, not get caught, AND EVEN assassinate the guards without getting caught either, if I take a few tries. But I seem perplexed at the fact that I don't see a lot to sneak around on the boat.
