beat the house of wolves in the fastest time possible and a secret cinematic will play out where all your fireteam and yourself will sudden be killed off with a 1 hp left and the final boss will execute everyone with a final blow and within the last second a shot blows of the final boss head clean off , as u all look from a distance into the shadows a familiar figure steps out all in green armor and a orange/yellow visor and with only a head nod the stranger steps back to the shadows again.
