Friends

As with any game, friends are an important part, but as it just so happens friends help to give you an edge in this game. While doing story missions you have the option to bring one of your friend's along with you. The Ranger that they have set as their avatar is the one that will accompany you. So be sure to change your avatar off the default Ranger! Additionally, you are able to send and receive 5 friend points every 20 hours that allow you to buy stamina. These friend points can be exchanged at a rate of 100 points per 20 stamina.
