Destiny Walkthrough: Warmind Pt. 2 & Last Array Pt. 1

After grabbing the gold chest by the water, head into the parking garage to fight The Fallen in a dark zone. If you die here you respawn outside the zone. Kill the boss and get ready for one of the toughest fights in the game:The Last Array. 

These enemies will charge at you and hit you from range. Cover is vital here. Keep moving and use the entire level to your advantage. Enemies will be coming from outside so it is best to stay inside and move backwards while they advance to thin them out and buy yourself time. You will encounter some knights and wizards as well. Fight through this messsed up renaissance festival and watch that array open up like a beautiful flower!
