Call of Duty 2 was really a big increase from the original Call of Duty. It's extremely fun, good graphics, and keeps you busy. One thing I really like is the open areas. It made it so you actually had to hide in places to get past the enemy. Grenades played too big of a part. When you couldn't pick off anybody with your gun, just toss a grenade in and watch their bodies fly. One tiny boring thing about this game is when you get to a part where you have to hold your position and keep the base clean of all enemies. You could be there for 20-30 minutes just watching and waiting to kill more people. There is also little variation in the way to fight, just go in get the same weapon you've been using the entire game, walk around walls and shoot all the enemies. But all that doesn't matter. Constant action, keeping you on your toes is all you need to realize anything but, YES! Like I said this is a must have for all PC owners. Get it ASAP.
