How about the blue flame helmet in Reach that you got if you had an iPhone and downloaded the Bungie app when it first came out? That was pretty neat...but sadly it made you more visible and a better target. Oh, almost forgot that it also gave you the Bungie banner that only employees could use up to that time. I lost count of all the people who didn't know better sending me friend requests cause they thought I worked for Bungie...stupid suckups.
