Destiny 2’s second expansion, Warmind, is almost upon us. Guardians are about to head (back) to Mars to explore the Red Planet’s thawing ice caps, and to deal with a previously frozen Hive army. The add-on will bring a second raid lair into Destiny 2, Spire of Stars, and a horde-style cooperative exercise called Escalation Protocol. In addition, Warmind comes with two new strikes on Windows PC and Xbox One, and three on PlayStation 4.

Bungie and co-developer Vicarious Visions are also bringing plenty of new features to all Destiny 2 players tomorrow, regardless of whether they buy Warmind, in updating the game to version 1.2.0. That set of features includes two new Crucible maps, although players must own Warmind if they want to use the new maps in private matches. In addition, the update will introduce Masterwork versions of exotic weapons, along with performance tweaks for a whole host of them.
