Just finished the Single Player portions of Call of Duty. I enjoyed the game, the mission variety was excellent. The first Tank level started to make me sick for some reason.. FPS never do that, but controlling that Tank was freaky. The 2nd level I didn't have any problems with it.
Most of it was fairly simple on the 2nd difficulty setting... except that shitty hold the bridge mission. At first you take the bridge over which is simple, but then holding it was hella tough.
