Activision has released the official launch trailer for the second Destiny expansion: House of Wolves.
The expansion pack will be around the size of a small game in itself, boasting new story missions, weapons, maps and gameplay modes.
While the trailer remains fairly mysterious in terms of plot, it does suggest that you'll be taking on The Fallen - one of the major foes in the first person shooter.
Going with the classic vengeance plot line The Fallen apparently feel wronged in some way, prompting them to exact terrible revenge. Of course preventing this will be you, armed with new weapons and equipment.
