I know this isnt related to assins creed however i have a MASSIVE TIP for sonic adventure 2 about the KNUCKELS STAGES. (No spoilers) Unlike the first game the rador only works on ONE EMERALD at a time. This causes a lot of people frustration as it makes the stages take way longer. However what most people dont realize is that most stages are broken up into 3 or 4 sections. Once you find an EMERALD in a section the next EMERALD wont spon there. For example pumkin hill has 3 mountains and some platforms in-between, once you find an EMERALD on the church mountan the other emeralds can only be on the train mountain or the tall mountain. I hope this helps you as the KNUCKELS STAGES can be very annoying if you dont already know about this.
