I actually preferred the base game over chaos rising, the Tyranids provide a real exciting and credible threat whereas the Chaos Space Marines come off as cartoonish and arrogant.

The overall length of the game was short and the character progression stops too soon, meaning that your main squads reach maximum level half way through the game!

The boss fights are basically bullet sponges with some annoying area of effect attacks.

Over all – stick to Dawn of War 2.
