All of the original Destiny’s PlayStation-exclusive content is, at long last, available on Xbox, finally bringing people on Microsoft systems up to speed after multiple years of lagging behind their Sony counterparts.

Thanks to a marketing deal between Sony and Destiny publisher Activision, the game and all of its expansions — and now Destiny 2 — have featured content that is available first on PlayStation, not Xbox. The content includes items like powerful exotic-level weapons; lengthy cooperative missions called strikes; quest lines; maps for the Crucible, the game’s competitive multiplayer component; vehicles such as Sparrows, a Guardian’s personal hovercraft; and unique sets of armor.
