Okay, I did strikes on the strike playlist and killed enemies with both grenades, melee, supers and every weapon. It still says 0/600. What the freaking hell do I have to do to get progress on the chest armor for the Titan? You all need to be more specific instead of putting "Strike playlist (vague symbol) 0/600". Am I alone on this s*** or is this getting aggravating for other players? I even did a strike that involved fallen enemies, still 0/300. Same thing happened previous years and still broken.
