The entire driving force in Destiny 2: Forsaken is revenge. This is an expansion that doesn’t focus on saving the day or preventing the extinction of mankind by disabling a space station super-weapon that can cause entire stars to go supernova. This is a chase, a journey to get your hands around the neck of Prince Uldren and squeeze the life out of his jerkass face once and for all, his true motivations be damned for killing Cayde-6. Kind of unusual, right?
