I just got Call of Duty for my compter and just actually finished Call of Duty2. I notice when I am playing Call of Duty 1 and go to do some objectives, they don't always work. For instance.....I was suppose to get in a car and went up to the car and couldn't get in it. I had to start the level over again and then it worked. Another thing is that my commander was suppose to give me explosives and he wouldn't and had to start the level over again and it worked. Did anyone else have this problem?
