Great Expansion with great new additions. Downside is it is a little Limited but this game still shines very well.
Firsts, first there is a new race added to the game. It is the Imperial Guard. Their primary soldiers are very weak in small numbers but in many can be deadly. Later on as new soldiers are available you will notice they are stronger and have a lot more endurance. Their vehicles are very strong especially the super tank the Baneblade, the Imperial Guard Version of the Land Raider. Sad thing is thier is only a limit of one so no easy victories.
The Campaign of Order goes that the Imperial Guard are after a super weapon known as the Titan to have to give to their Emperor. The Eldar though are trying to use the Titan to activate a weapon of their own named the Soulstone to destroy a deadly species known as the Necrons. The Campaign of Disorder is about the Orks and the Chaos trying to eliminate all species on the planet to claim it as their own. Their Campaign is a little more difficult especially with the Orks if you have low WAAAAGH!! resource.
In the game units are much cheaper so no more one man armies can now win a skirmish game. Also more units have been added to the different races to add a little spice. There are also some great maps on Skirmish Mode. Sadly a lot more could have been added to the game such as adding the Necrons to your skirmish available armies. More Vehicles and Unique Units could also have been made. But it isn't a bad game. It still sucks you in very well and is as bloody and gory as the last one.
In conclusion Winter Assault is still a great game and great expansion. More could have been added but that doesn't spoil the game at all. I do wish though that the story of the first game would have been continued in this one. Still Dawn Of War: Winter Assault is a great game that you will fall in love with and enjoy.
