At the end of the day, Call of Duty 3 is an "OK" game trying too hard to be a good game.
First the gameplay is OLD. It's hard to make a first person shooter seem new (Halo 3 has a lot of work to do) but this game doesn't even try. Firing and shooting almost any weapon is unsatisfying, and so is killing anyone in the game, as any and all enemies fall with just one of two shots, and die with a sort of "who cares" animation. The graphics are pretty good. The foliage and lighting and texture detail is great for the most part. There were many times, however, where I would be taking cover next to a fence, a wall, or something, and the textures would look extremely blurry. Not nit picky blurry, but actually blurry, and they look out of place next to other nicer textures.
The sound is great. There isn't much to say because all you hear the WHOLE game is the same 3 or 4 voice actors yelling back and forth about nothing much in particular. it begins to get annoying. But the music is excellent, which saves the day.
The online multiplayer is decent. It is a little boring, as the same lame gameplay hinders the online gameplay. People are constantly dieing left and right, leaving no sort of cohesivness to what is actually going on in the game. You spawn, run around for 20 seconds or more hopeing to catch someone off guard before they do the same to you and then shoot 2 or 3 shots and they die, and then you die ofcourse because someone just did the same to you....repeat until the match is over. All in all, I was expecting more from reviews and personal testimonies from people. But at the end of the day, Call of Duty 3 needs to either (A). Be put to rest for something newer and fresher, or (B.) Be reworked and revamped. Don't buy it, just rent it.
Also: No More World War II Games!!! After playing this game, I am realizing how discriminatory and rascist this game was to Black people living in America. (Yes I Know Black people living in America fought in the war, but do the history as to why...) This game is the same old story told over and over and over again....but maybe that is why the masses like it so much, along with other previously mentioned reasons...
