The weekend has arrived, meaning mysterious Destiny merchant Xur is back, as well. The vendor is the only one in the game to sell exotic weapons, and every week is different than the last.

Xur is always in a new location from one week to the next, and his stock differs every time. He appears on Friday and departs (usually early) on Sunday, offering one exotic armor item for each class, an exotic weapon, and an exotic engram to gamble on.
This week, Xur is located in the Hall of Guardians, where you find the Crucible and Vanguard vendors--down the main staircase in the center of the Tower. He's at the back and off to the right, a location he has been before, and he's brought a great selection this week.
A Guide To Exotic Gear In Destiny
The Suros Regime--the most powerful exotic Auto Rifle you can buy (bested only by Raid reward the Vex Mythoclast)--is the weapon on sale this week. Anyone who has saved up their Strange Coins will be very pleased, as it will cost 23 of them. The armor for each class is a chest piece this week, priced at 13 Strange Coins each. The Titan's is The Armamentarium, the Hunter's the Crest of Alpha Lupi, and the Warlock's the Voidfang Vestments.
The engram (23 coins, also) is for a random exotic gauntlet, but you may not get one for your class! The best way to come up with Strange Coins is the weekly strikes, which award three, six, and nine coins per difficulty level. You can only cash in once a week, though, so you'll need luck in finding Strange Coins from engrams and Crucible matches--happy hunting.
