This one's the only Call of Duty worth the money and the time, fast paced, funny, action everywhere, missions are nice and overall level design is very detailed, sometimes AI can be kind of dumb and cover themselves meters away from the action letting you do and recieve all the bullets, but for the most times AI works kinda good.
This is a great representation of the events during World War II, if you had to chose to buy just 1 of all those COD titles, don't hesitate and get this one, you will not regreat it, you will enjoy it.
