If you liked dawn of war 2, you will love this
good stuff:
lots of content
you can import your saves from dawn of war 2 onto this, which is a great feature
great multiplayer (even though it can lag sometimes) as well as a new mode, last stand
the corruption/redemption thing was just a plain awesome idea
great graphics
lots of customization
The only bad thing that I can really think of is that the campaign mode, while it is great fun, is quite short. overall, this is a superb game, even if this is coming from a huge dawn of war fan.
As I've already said, if you liked dawn of war 2, you will love this and it is definitely a worthwhile buy if you like strategy games.
