Xur, that shadowy Santa Claus from the cosmos with a Cthulu-ian face, has made his first appearance in Destiny 2. Here's an in-depth look at what he's selling.
Xur's appearance in Destiny 2 is much like the original game: the mysterious merchant is still selling four exotics: one weapon and three armor-based items each for a Titan, Warlock, and Hunter. Unlike the original Destiny, however, Xur is actually found in the open world this time around and not in a safe space like a town. Also he's not exactly hidden this time, but marked with a "IX" indicator on a planet's map.
For Week 1 users can find Xur on Nessus near the Watcher's Grave region to the northernmost section of the planet. If you can't find him right away be sure to look up--Xur is conspicuously tucked away on an autumnal tree branch next to the crumpled corpse of a Hezen Collective Vex.
