if u wait more than a month it ends ur account
you play the game and once u reach level 80 and beat it you go to barracks and select prestige mode and enter it to prestige
Alright entering prestige mode in MW3 is pretty easy. You can only enter prestige by leveling up to 80. Once you reached level 80, go to the multiplayer menu, play online whether it be on the Playstation 3 or Xbox 360, go the icon where it says Barracks, once you go there Prestige mode should be ready for you.
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.
First you have to get to level 71! then you enter prestige mode which is located in the barracks option. -------------------------------- I don't think there is a level 71. You just need to get to level 70 and go to the barracks option.
to unlock prestige mode you have to get to level 65 in multi player mode
prestige mode is basically trading all your earned weapons and returning to level 1 for a different emblem. you can prestige 10 times.
Nothing will happen
quite simple really just reach level 70 which gives you the rank of commander. then go to barracks in the xbox360 live menu. it will say on a little meter xp bar "prestige". the simply press it and you are there! Except that you must be careful about deciding to enter prestige mode, because when you enter it you will lose all of your weapons, killstreaks, and perks. But you will keep all of you titles and emblems that you earned.
In MW2 you get a new emblem and an additional class to use.
yes
If you want to keep your stuff then dont prestige, but if you want to prestige you are going to lose your stuff every time you do it.
By old, do you mean the previous one you had? You can't, unless you quit going into prestige mode, Then you are stuck with the one you have.
