With Destiny 2's latest Faction Rally underway, the mysterious merchant Xur has reared his unsettling face once again on PC, PS4, and Xbox One. He has a selection of Exotic items for sale, as always, along with a special Engram and a way to boost your chances of securing additional Exotics. Here's exactly what Xur is selling this week and where to find him.

With this week's Flashpoint on Mercury, Xur has taken up residence on the Tower, where anyone (DLC owner or not) can find him, provided they've finished the campaign. He's in his usual spot on the right side of map, just behind where the Dead Orbit Faction is set up. A staircase just behind that area will lead you right up to Xur.

In terms of items, Xur as always offers the Fated Engram. Although pricey at 97 Legendary Shards, this is guaranteed to reward you with an Exotic you don't already own. The Three of Coins is another option and will boost the likelihood of obtaining an Exotic item drop for four hours. Each class gets one piece of (non-Curse of Osiris) Exotic armor, while the weapon up for grabs is the Tractor Cannon. This Exotic Shotgun, which resembles Portal's Portal Gun, is worth the price of admission alone for its ability to hilariously knock enemies back (and right off the level, if you're positioned correctly). Here's everything for sale:

Tractor Cannon (Exotic Shotgun) -- 29 Legendary Shards
Knucklehead Radar (Exotic Hunter Helmet) -- 23 Legendary Shards
Actium War Rig (Exotic Titan Chest) -- 23 Legendary Shards
Transversive Steps (Warlock Leg Armor) -- 23 Legendary Shards
Fated Engram -- 97 Legendary Shards
Three of Coins -- 31 Legendary Shards
Xur will have all of this for sale from now until the weekly reset on January 23. That's also when the current Faction Rally--the first of Season 2--runs until. Despite what players assumed, you can't actually obtain any of the new Faction weapons right now, prompting an apology from Bungie for not being clearer about how the event would work. There is, however, other new items to obtain; you can see all of the new Faction Rally gear in our gallery.
