Even on lower settings, Dawn of War II is impressive. While power armor-clad space marines have become a bit blasé in the last year or two, there's something about Warhammer 40K's style that makes it stand out. Most of this has to do with the small touches. Environments look lived in and don't have the "game level" look; instead each looks like a functioning environment, thanks in large part to the smaller details, like undergrowth and the swaying of alien plant life.
These details carry through to the units, which have their own particular style. Armor has a gritty, metallic look and each weapon has it's own distinct effects. Troops are also customizable right down to the ability to paint their armor - allowing for a personal touch.
Unfortunately, the audio doesn't feature the same level of polish. The important sounds, namely explosions and weapon fire, are great but the voicework is a bit of a deal breaker. Mission chatter has a bit of a "meathead" feel, which adds a certain level of charm. However, mission briefings are forgettable. Mission details are offered by a high-ranking officer, though it isn't likely you'll continue listening to him past the second or third briefing. Instead, he'll sound like someone droning on while you equip and customize your troops.
