The Multiplayer Beta will run from Feb 1st until Feb 24th.

Ten years after the events of Chaos Rising and the fall of the Blood Raven’s Chapter Master to the forces of Chaos, Sub-Sector Aurelia remains in a constant state of warfare. The pirate Freebooter Orks have arrived to take advantage of this and loot the sector, the vile forces of Chaos continue to spread their blasphemy, the Eldar of Craftworld Alaitoc work to recover key artifacts from their past and the feral Tyranids remaining from the failed Hive fleet invasion have suddenly re-established contact with the Hive mind.
