While you're giving thanks this weekend remember your old pal Xur, who pops up in Destiny 2 for PS4, Xbox One, and PC every week with brand new Exotic weapons and gear for you to pick up. Destiny 2's equivalent of an Amazon Prime Now deliveryman is hanging out on Io and, unlike the other locations he usually pops up in, this one can be tricky to get to.

While navigating to his general area is fairly simple if you open up the map and put a marker on him, once you're there, you'll need to keep an eye open for a very small, very dark cave entrance. It's up in the far left-hand side as you enter Giant's Scar. If you're having trouble finding it, check out our Xur location guide video above, or keep a close watch on other players and you'll see them going in and out.
