The premium add-on pack called The Dreadnought, adds a new multiplayer mode called Dreadnought Assault where both teams battle to capture a central location on the map and the winners spawn a player controlled Dreadnought. The Dreadnought is armed with an Assault Cannon / Auto Cannon, a Meltagun and a Power Fist / Power Claw and must capture points across the map to score points for their team. Once the Dreadnought is destroyed a new spawn point will appear.
The Dreadnought DLC also includes three new multiplayer maps Desolation, Dome Mechanicus and Chem Refinery, as well as new achievements and trophies.
