Vanguard

Vanguard is a speculated and unconfirmed character class which was briefly mentioned in IGN's write-up of the Reveal Press Conference.

No other known article about the press conference mentioned the Vanguard class, giving rise to speculation that this was an error by the IGN reporter who covered the story. It is unconfirmed by Bungie whether this is an actual class, and Bungie has not commented either way.
