When I first played Call of Duty 2, I loved the sight, the sound, and the engine of it. I loved it most of the way through, until the gameplay got a little repetitive. Overall, Call of Duty 2 is a great game with a multiplayer that could match that of Halo 2, it never got boring. Although ther were some minute flawes in it, the gorilla tactics that the enemy used on you when you got a little too close to them, and the fact that there were barely any enemy snipers to shoot down.
This is a great game if you want a relentless barrage of gunsmoke at your left and right, and the multiplayer is one that you can spend a couple of days just playing that.
