Graphics-wise, Call of Duty 3 isn't as detailed and beautiful as its other next-gen versions (I've been watching Psibabe play the same game on the PS3 for a few weeks now ... and all I can say is Wow!), but it packs a punch. Most of the textures are a little choppy and slightly better than what you would expect to see on a GameCube, but atmospheric effects like smoke bombs are smooth and a joy to watch (if you have time in the middle of the war, of course). Even if the visuals aren't as powerful as the Xbox 360 or PS3 versions, Wii's Call of Duty 3 still conveys the jarring and hectic atmosphere that this series has done so well at portraying.
The game's audio is nothing to sneeze at either. Everything from the report of machine guns to the blast of mortars and tank fire just pulls you in and keeps you in 1940's France. Vocals are clean and clear, but some of the in-battle comments shouted out by your cohorts get repetitive real fast. I don't know how many times I would hear someone yell out "I got one" or "I'm out of ammo" or "Germans in the clear", but it was a lot and it started to get painful after a while.
Personally, I felt like one of the best aspects of this game's presentation, both visually and aurally, was when you find yourself too close to a mortar blast or a grenade. The camera shakes, the volume goes down and your ears start to ring. The overall effect is jarring and really un-nerves you.
