Destiny‘s Rise of Iron expansion is almost here. If you want to play the second it unlocks, Bungie has now confirmed precisely when the game’s fourth add-on will arrive. In a statement on its website, Bungie revealed that Rise of Iron will come out tomorrow, September 20, at 2 AM PT / 5 AM ET.

GameSpot will run a livestream event overnight to show off the new Rise of Iron content. Check back soon for more details on the specifics about this event.

Rise of Iron is Destiny’s fourth expansion, following The Dark Below (December 2014), House of Wolves (May 2015), and The Taken King (September 2015). The expansion comes with a new snow-covered region called The Plaguelands, as well as new campaign and multiplayer content.

The expansion sells for $30 on its own. Also coming out tomorrow is Destiny: The Collection, a $60 bundle that comes with Destiny’s base game and all DLC, including Rise of Iron. Unlike the three previous expansions, Rise of Iron is only coming to PlayStation 4 and Xbox One.

Ahead of Rise of Iron’s arrival, Bungie today released a pair of updates that fix bugs and more.
