The next Destiny expansion is called The Taken King, according to marketing materials sent to Kotaku. It’ll be out on September 15 and will open up a new subclass for each of Destiny’s three classes, according to the leak.

This evening, a tipster sent over a large marketing sheet for The Taken King, which we’ve been able to corroborate with other sources. The sheet—which lists The Taken King at $40—offers a handful of details surrounding Destiny’s next expansion pack. For example, it confirms the existence of a new subclass for each of the game’s three classes, along with a new elemental super ability: an electrical storm for Warlocks (arc); a gravity bow for Hunters (void); and a flaming hammer for Titans (solar). HardcoreDestiny players will notice that each of these abilities revolves around the element each respective class lacks today.

In addition to the usual additions we’ve seen in both other Destiny expansions so far—new Strikes, new PvP maps, etc.—The Taken King will have a raid pitting players against Oryx, father of Crota, who is apparently looking for revenge (and leading a new army of baddies called the Taken).
