I just played about five minutes of it, and two things are clear.
One, they seem to have borrowed heavily from the Ninja Gaiden school of combat.
Two, the game no where near follows the storyline of the actual book.
That all said and done... if they keep me amused I wont cry bloody murder. After all, if the first Pirates of the Caribbean taught me anything, it was that writers pulling things out of their butts CAN occasionally strike that gold turd.
