bug to hell, suffer from the same problem asscreed had in the 360 era, manage to fuck with their own puzzle (door puzzle solution being half right and half wrong while gollum says the correct shape), script not activating and somehow manage to make the worst chapter system in history (the checkpoint you had in your playthrough is your chapter mark, so if it was messed up you'll load a messed up chapter). you play the same level for 4 chapter. It's insane to think this game had a budget.
