Well I just beat the campaign of Call of Duty 3. It was a lot of fun and very intense at times. I think the best part of this game like and CoD is the atmosphere. They really make you feel like you are there. The SP is quit linear not as open as CoD2. I find it to be more of a Medal of Honor type game. It was a little to short for my liking and there was really no huge ending or anything. I fell like the last level could have been any of the levels, the intensity and difficulty never really changed. All in all though I would give the SP an 8 out of 10 which is an awesome score.
