After the official release of the The King and the Warlord DLC on October 20th, Creative Assembly has uploaded a video to their youtube channel giving a detailed walkthrough of how one would go about the initial stages of leading one of the Dwarvish clans under King Belegar Ironhammer (depicted above in all his Dwarfish glory.) Assuming you haven't already beaten the campaign, the video offers some helpful tips and suggestions as to what you should be doing once the game loads and what you can expect.
Featuring King Belegar himself, the tutorial explains that you'll be starting far from your ultimate objective, Karak Eight Peaks and but close to your hated rival the Goblin Warlord Skarsnik, who stole your ancestral home from your family. You'll want to secure the rest of your starting region and wrestle the two provinces under the control of the Greenskin Broken Nose tribe. Rapid expansion might be the only legitimate path forward, as you'll be suffering a 50% unit upkeep cost, which is going to hurt you seriously. The campaign is rated HARD for a reason. The next thing on your to-do list before the long march back home would be to find allies, either in the human Border Princes or the local Dwarf Kings, all of whom will be dealing with their own Greenskin issues or squabbling among themselves as Skarsnik begins to build up his forces in the region.
The King and the Warlord is the second legendary lords DLC pack, the first featuring The Empire and the Vampire Counts. This one naturally focuses on the Dwarves and the Greenskins. The DLC also features new units for both factions, new battle maps, and quest lines. It should be noted that the video is focusing on King Belegar, but you do have the option to play as the Night Goblins. The goal for either faction is Karak Eight Peaks, one of the greatest Dwarf cities in the Worlds Edge Mountains and second only to the great Dwarf capital in wealth and splendor. Belegar must take it from the Goblins and Skarsnik must re-take it from the Goblins who have betrayed him and revolted, taking the ancient city for themselves.
The DLC can be found on Steam along with a complete list of all new units and changes to tech trees for both Dwarves and Greenskins and is available for $7.99
