We come to the end of our journey. The Vex are everywhere so take it slow and move forward only after you have cleared them out. When you enter the final area you will face 3 of the same mini boss gate lords from before as well as adds. Take out the 3 bosses using cover, grenades, bullets, and your infaliable fashion sense. Once defeated the weird black thing in the middle that no one has told you anytning about and we can only assume is The Darkness fades away. Congrats. You win!
