Maybe not all of the perks, but I could see some of the highlight perks with an added link to the online shop w/ more info. Nice idea Reggles.

Well the menu could be something like, Ranks, Items, Pets, etc and when you click on it there is a tab where it lists out what perks they get and what they do. Then maybe in the main menu it would give a condensed list for players to just browse over if they are just interested.
