In MW2 you get a new emblem and an additional class to use.
prestige mode is basically trading all your earned weapons and returning to level 1 for a different emblem. you can prestige 10 times.
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
yes
to unlock prestige mode you have to get to level 65 in multi player mode
Nothing until you get enough points to go into prestige mode.
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.
it is when you reach a certain level and you are asked to do it all over again except you get higher prestige. When you reach level ***55*** you are asked do want to prestige.
10 prestige level 70 commander
From prestiging in modern warfare 2 u get an extra custom class and new emblems and titles.
To get to the first prestige in Call of Duty: Modern Warfare 2, you must reach level 70 on online multiplayer, then complete the XP for Level 70, then go to the Baracks in the lobby and there will be for choices that you will be able to select. Challenges, Accolades, Leaderboards and Prestige Mode. Select Prestige Mode and keep pressing to appropriate choice until you have prestige, you should have a new badge next to your name and should by Level 1 again. Hope this helped. :)
bragging rights. plus you get a funny little symbol next to your name, so everyone knows you're not a noob.
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.
