To change equipment (for example, to use a new sword), enter the "Equipment" screen at a shop. You can now switch items. Note: Some items, such as certain outfits, can be switched in the basement of the homestead manor.
As young Connor/Ratohnhake:ton, Hold [Run] and lightly press the Left Analog-stick in the direction you wish to move. Instead of running, Connor/Ratohnhake:ton should skip.
Use the following trick to go from notorious (wanted) to incognito (not wanted) without paying a bribe to the crier or the printer, and without tearing down any posters. Once you are anonymous (unseen by the enemy) you can use "fast travel" and when you do so, you will become incognito.
Saving time with Nathem:
During the first two or three sequences where you play as Natham, do not spend any time acquiring any amount of money or weapons. You will lose them all after you switch over to Conner.
During the mission where you attempt save the man who is trapped in the rapids and held by a log, try to save him just as he is about to go over the waterfall, and as close to the death zone of the falls as possible. When you dive, aim directly for him. If done correctly, the screen will be distorted (even during the intermission sequences). It will look much in the same manner of when Charles Lee's friend hits Conner over the head and he just wakes up. The screen will remain like this until you are able to pause the game.
