The game play and storyline as far as i can tell is great as usual, but the problem would be of a possible glitch in the game. Taking the tunnels has caused the character I am playing to randomly be ported to the patheon (even if that wasn't where I was going). After running around roma, i would randomly be desynchronized, without warning. (aka. death) I dont really know for sure if it was just my copy of the game, or if there have been other issues with the game such as this.
