YouTube ghost locations, beat every mission/strike/raid, PvP, earn (x) amount of kills with (y) weapon, kill enemies of all kinds. Speaking of ghosts, don't forget to grab the ghost sitting near the railing in the Iron Banner plaza. EDIT: Misread. Took out the exotic weaponry part, just got home and can type and read much better on laptop over ios. Plus well, can't edit while driving. :/ *came back from coffeehouse.* On another note, this drink is pretty damn awesome and regret nothing.
