Unless there's a mod where guns use the same ammo, none
No they are not because Call of Duty World at War in set during World War II
Call of Duty isn't any good because it's the same thing just different guns and the same stats for the guns but the only thing that ever changes is: a) the campaign which is typically really bad. b) the names of the guns but they keep the same stats as guns in the last game. c) the kill streak rewards and d) the perks have their names changed. The online play for Call of Duty really sucks because all it is is he same thing from the last game with the guns looking different but have the same stats, some new kill streak rewards that are basically the same thing as they were last game. Also, everyone that plays Call of Duty is a moron.
As far as I know, yes. You can. There technically the same as normal guns. In a certain way.
No, all your guns are reset to the same as you were when you were level 1. The only thing you unlock when prestiging is emblems and titles.
Yes. Call of Duty 4 is the same as Call of Duty: Modern Warfare
The Previews of the game have the same armor and gun ammo I think they ran out of ideas so they are taking other people's ganes
The Call of Duty games are called the same in German.
No, it is a separate game
Call of duty world at war was created by Treyarch, the same team that made call of duty 3 and call of duty black ops.
