Basically at launch, PS4 and PS3 owners will be on the receiving end of exclusive access to a unique co-op Strike located on Mars, in addition to an exclusive competitive map, alongside a whole bunch of exclusive guns, gear, and ships.
First of all, the Dust Palace Strike, being an exclusive three-player cooperative Strike is playable alongside friends or match made. You will be tracking a Cabal extraction team all the way through the husks of an ancient human skyscraper known as the Dust Palace (hence the name), all the while having to combat a new enemy known as the Psion Flayers.
As for the Exodus Blue Competitive Multiplayer Map, this mid-sized Crucible arena will pair up with Control and Skirmish game modes. The Exodus Blue is a long-dead vessel that will now be the venue where Guardians challenge each another.
Do expect a slew of new gear to boot, where the Warlock class will receive a Manifold Seeker armor that was specially constructed to assist Warlocks in surviving the secret realms of the Vex. The Titan class has not been left out, having received Vanir, a battle-tested armor set which was forged to protect Titans against the heavy firepower of the Cabal. As for the Hunter class, they will have a durable all-environment wire-weave known as Argus to help them scout the frontier. [Press Release]
