If you preorder Total War: Warhammer 2 you will get an awesome Norsca faction to play with in your original game. I preordered the game and I must say that I've been having a tons of fun with Norsca faction. It can easily be my favorite Warhammer faction because of the new mechanics and very cool looking new units Norsca brings to the table. On a grand scale campaign Norsca starting location is in the north where you will have to fight other Norscan tribes or unite them all under the same banner. Who better to do that other than Wulfrik the Wanderer, crazy Viking looking dude with a ghost ship that can travel all over the world and hunt rare creatures in order to please the gods of chaos. There are not many resources in the north so you can get gold mostly by raiding and pillaging provinces.
You can also raze the cities and build totems for 4 chaos gods, each giving different bonuses depending on how much favor you have with them, for example sacrificing for the Eagle (Tzeench) you will get you your own Lord of Change (greater demon), but you have to chose only one god to follow for the strongest of buffs and gifts.
Another very cool new mechanic is monster hunting, those are special quests where you will have to track and kill the unique monsters in the old world. Those battles are very fun and actually hard to complete, but the bonuses after you win them are epic. For example you can hire unique Frost Wyrm in your army, or learn rare and devastating spells to use in battles. Unit roster of Norsca is very cool, you will have all sorts of wild men and beasts to control. My favorite units in the whole game are from Norsca faction, units like skinwolves, chaos mammoths, frost wyrms and ice trolls.
This preorder DLC is such a sweet package if you own TW: Warhammer and will hype you even more for Warhammer 2 that is coming out at the end of this month.
