When you reach level 70 go to the barracks and there will be a option called prestige mode basically you restart with nothing except your titles and emblems and you unlock new challenges and its rumoured that you dont need as much XP points to level when you are in prestige mode.
You unlock it by getting to 10th Prestige.
yup
2nd prestige
Probably not, but hay? Maybe.
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.
